The technical field to which the invention relates.

The present invention relates to a device for processing service, provided by a heat pump, and the way to manage them and, more particularly, to a device and method for determining the operating status of the heat pump system of the device for processing service and support steady state.

Background of the invention

Basically, the device for processing service, which has the function of drying, such as a washing machine or a drying machine for clothes, is used for drying clothes, fully washed and dehydrated through a load of Laundry in the dryer, the hot air flow into the drum and then evaporation of moisture from the clothes.

Below, a device for processing service will be explained on the example of the drying machine for clothes. Drying machine for clothes includes a drum mounted for rotation in the housing and accommodation linen, drive motor, is arranged to actuate the drum, the discharge fan configured to supply air into the drum, and means of heating performed by the heating of the air lodged in the drum. The heating means may use a high-temperature electric resistance heat generated by electrical resistance, good discharge performance is observed or the heat of combustion generated in the combustion gas.

The air is released from the drum, has a high temperature and high humidity due to moisture of the Laundry in the drum. In accordance with the processing method of air with an average temperature and high humidity drying machine for clothes can be divided into a condensing type (circulation type) and outlet type. Drying machine for clothes condensation type made with the possibility of condensation of moisture contained in the air with an average temperature and high humidity, by circulating and cooling to a temperature below the dew point through the condenser without venting to the outside. Drying machine for clothes prom type is configured to direct exhaust with average temperatures and high humidity which has passed through the drum to the outer side.

In the case of a drying machine for clothes condensation type air must be cooled to a temperature below the dew point to condense the air out of the drum. The air must be heated by means of heating before re-submission to the drum. Here, the air can lose its thermal energy by cooling. For heating air to a temperature high enough for the process of drying required will augment the capacity of the heater, etc.

In the case of a drying machine for clothes outlet type also must be vented with average temperatures and high humidity on the outside for fresh air with high temperature and heat of outdoor air to a predetermined temperature by means of heating. In particular, high-temperature air is released to the outside, includes thermal energy transferred by means of heat. However, heat energy is released to the outside, resulting in lower thermal efficiency.

To resolve these problems, a device for processing service, increase energy efficiency through energy storage needed to generate a hot air flow, and energy released to the outside without using. In one example of the device for processing the service has recently been proposed a device for processing service with the heat pump system. Heat pump system includes two heat exchanger, a compressor and an expansion device and increasing energy efficiency due to the accumulation of energy produced by the hot air flow and re-use of energy for heating air supplied into the drum.

More specifically, the heat pump system contains the evaporator on the output side and the condenser side suction is near the drum. Heat pump system transfers the heat energy of the cooling agent through the evaporator and transfers thermal energy to the refrigerant to the air supplied into the drum through the capacitor, thereby generating a hot air stream using a waste of energy. Here, the heat pump system may further include a heater made with the possibility of re-heating the air heated while passing through the condenser.

Technical problem

This heat pump system must maintain a steady state during the drying process to improve energy efficiency. Accordingly, the condition of the heat pump system should be checked constantly, and each element must be regulated on the basis of proven state of the heat pump system to maintain steady-state mode.

Solution

Therefore, the present invention is a device for processing a service that checks the status of the heat pump system and supports the steady-state mode.

Another objective of the present invention is to provide a process control device for processing service that checks the status of the heat pump system and supports the steady-state mode.

To achieve these and other advantages and in accordance with the present invention, as embodied and broadly described herein, the described method of controlling the device for processing the service, contains the drum, is arranged to accommodate the object to be dried, means of suction air, made with the possibility of formation of flow of air supplied into the drum, means exhaust made with the possibility of the formation of flow of air discharged from the drum, a condenser located to heat air sucked into the drum through the means of suction air, the evaporator located for cooling air discharged from the drum through the medium of the discharge of the air compressor configured to compress refrigerant, filed from evaporator, and an adjustable expansion device configured to expand refrigerant submitted from the condenser, and having an adjustable degree of opening, and the method includes measuring the temperature (Tei) of the cooling agent, filed in the evaporator, and temperature (Tci) of the cooling agent, filed with the compressor, check the opening degree of the adjustable expansion device, when the difference (Tci-Tei) of temperatures between the two measured temperatures is less than a preset first value, and decreasing the opening degree of the adjustable expansion devices is in accordance with the value of the opening degree of the adjustable expansion device, moreover, at the stage of reducing the opening degree of the adjustable expansion device width decrease the degree of opening when the opening is small, already widths decrease the degree of opening when the opening is large.

In the present invention heat pump system can be adjusted to sustain a steady state by regulating the flow rate of the cooling agent by changing the opening degree of the adjustable expansion device. In the case of devices for processing the service, which has the function of drying, the heat transferred in the heat pump system, the evaporator may vary considerably in accordance with the amount of Laundry placed in the drum, and humidity linen. Consequently, the adjustable expansion device, you may need to adjust according to speed the process of drying.

More specifically, the refrigerant can be fed to the compressor through the evaporator in the gas state, not in the liquid state from the point of view of working conditions and service life. A sufficient amount of heat can be transmitted to the evaporator. However, if a sufficient amount of heat cannot be transmitted to the evaporator, the flow rate of refrigerant passing through the IP is Ariel, can be reduced, so that the refrigerant evaporates enough.

Heat transferred to cooling agent from the evaporator can be obtained from air discharged from the drum. However, the amount of heat transferred to the evaporator output air may vary in accordance with the speed of the drying process. More specifically, during the initial drying process produced the air can absorb large amounts of moisture from the sheets and, thus, have high humidity and low temperature. Consequently, much of the heat energy produced air can exist in the form of latent heat, and only part of it can exist in the form of sensible heat. This may be the reason that the amount of heat that can be obtained by the evaporator, is relatively small. Therefore, verify that the refrigerant has not been sufficiently vaporized during the initial drying process, the flow rate of refrigerant passing through the evaporator must be quickly reduced.

More specifically, during the initial drying process, the sensitivity to the evaporation of the cooling agent about the change in the opening degree of the adjustable expansion device may be low. Accordingly, preferably sufficiently increased the ü width changes the degree of opening.

On the other hand, if the drying process is carried out to some extent, the amount of moisture contained in the Laundry, can be small. Because the energy produced air exists in the form of sensible heat, the heat transferred refrigerating agent through the evaporator may become relatively large. In this case, unlike the initial drying process, the sensitivity to the evaporation of the cooling agent about the change in the opening degree of the adjustable expansion device can be high. Accordingly, it may be preferable to reduce the width changes the opening degree of energy efficiency devices for processing the service.

In the present invention, the evaporation of the cooling agent can be checked by changing each parameter of the state of the refrigerant supplied to the compressor, and the refrigerant supplied to the evaporator. For example, the evaporation of the cooling agent may be determined using the temperature difference. If the refrigerating agent was sufficiently evaporated (received enough heat), the refrigerant supplied to the compressor may have a high temperature. Therefore, the evaporation of the cooling agent can be indirectly tested on the basis of the temperature difference, measured in advance when theplease the nye the system is in steady state.

The speed of the drying process can be directly checked using the opening degree of the adjustable expansion device. When you start the drying process adjustable expansion device can be adjusted for maximum opening, so that a sufficient amount of heat is transferred to the intake air through the condenser. With further implementation of the drying process, the degree of opening of the adjustable expansion device may be gradually reduced. Therefore, the speed of the drying process can be verified by checking the degree of opening of the adjustable expansion device. Alternatively, the speed of the drying process can be checked by determining the humidity of the output air. More specifically, the speed of the drying process can be checked on the basis of the fact that our air has a high humidity during the initial drying process, but has low humidity in the further implementation of the drying process.

When determining that the temperature difference is less than the reference value, means that the evaporation of the refrigerant is insufficient. Therefore, the flow rate of refrigerant can be reduced by reducing the degree of opening is adjustable is about the expansion device. Here, the width reduction of the degree of opening can be set differently in accordance with a proven degree of opening of the adjustable expansion device. For example, the width reduction of the degree of opening can be set in proportion to the degree of opening. This can increase energy efficiency and sustainable to maintain heat pump system.

Alternatively, the range between the maximum degree of opening and the minimum degree of opening of the adjustable expansion devices can be divided at least into two parts and the range of decrease the degree of opening can be set in accordance with each part. Here, the range of decrease the degree of opening corresponding to the portion having a greater degree of opening can be set already range decrease the degree of opening corresponding to the part having a small degree of opening.

As the adjustable expansion device can usually use the linear expansion valve (LEV). The degree of opening of the adjustable expansion device can be adjusted in proportion to the number of pulse signal. Therefore, the stage of reducing the opening degree of the adjustable expansion device made in the form of linear expansion valve (LEV), can switch the diamonds in the reduction of the number of pulses of the signal served on the adjustable expansion device.

The method may further include decreasing the opening degree of the adjustable expansion device at half or less than when you begin the drying process to actuate the compressor. This can prevent the passage of a large quantity of liquid refrigerant remaining in the evaporator or compressor after completing the drying process, in the compressor. Here, the degree of opening of the adjustable expansion device can be reduced to the minimum value.

The method may further include changing the opening degree of the adjustable expansion device to the maximum value after actuation of the compressor during a specified time in the state in which the degree of opening has been reduced. It can provide maximum actuation heat pump systems and, thus, to maximize the amount of heat recovered from the produced air. Here, the preset time during which the compressor is powered in a state in which the degree of opening has been reduced, can be defined as the time taken for the occurrence of heat pump systems in the established mode after actuation, dostat is offered, in order not to remain liquid refrigerating agent.

In some cases, the difference (Tci-Tei) of temperatures between the two measured temperatures may exceed the second value. More specifically, when an excessive amount of heat was transferred to the refrigerating agent produced by air through the evaporator, the refrigerant may overheat and reduce system performance and shorten the service life of the compressor. Accordingly, the method may further include increasing the opening degree of the adjustable expansion device, so that the temperature of the refrigerant is returned to the normal range. On the stage of increasing the opening degree of the adjustable expansion device width increases the degree of opening may be variable in accordance with the degree of opening of the adjustable expansion device. The width increase of the degree of opening when the opening is small, it may be installed already widths increase the degree of opening when the opening is large.

The range between the maximum degree of opening and the minimum degree of opening of the adjustable expansion devices can be divided into at least two parts and the width increase of the degree of opening can be set in accordance with each part. Here, the widths of which increase the degree of opening, corresponding to the part having a small degree of opening, may be already installed width to increase the degree of opening corresponding to the part having a greater degree of opening.

On the stage of reducing the opening degree of the adjustable expansion device in the case when the width of reducing the degree of opening is determined in accordance with the humidity of the output air, width less open when a certain humidity is low, can be installed already widths decrease the degree of opening when the humidity is high. The range between the maximum and humidity minimum humidity of output air can be divided at least into two parts and width decrease the degree of opening can be set in accordance with each part. Here, the width reduction of the degree of opening corresponding to the part having a low humidity, may be installed already widths decrease the degree of opening corresponding to the part having a high humidity.

To achieve these and other advantages and in accordance with the present invention, as embodied and broadly described in this document also describes a device for processing the service, contains the drum, is arranged to accommodate the object to be dried, means the aircraft is syvania air, made with the possibility of the formation of the flow channel for the air supplied to the drum, a means of venting made with the possibility of the formation of the flow channel for the air discharged from the drum, a condenser located to heat air sucked into the drum through the means of suction air, the evaporator located for cooling air discharged from the drum through the medium of the discharge of the air compressor configured to compress refrigerant supplied from the evaporator, and an adjustable expansion device configured to expand refrigerant supplied from the condenser, and having an adjustable degree of opening.

The controller may divide the range between the maximum degree of opening and the minimum degree of opening of the adjustable expansion device at least two parts. Here, the width changes the degree of opening corresponding to the portion having a greater degree of opening can be set wider than the width of reducing the degree of opening corresponding to the part having a small degree of opening.

The preferred embodiment of the invention

Details will be made reference to the preferred embodiments of the present invention, examples of which are depicted in the accompanying drawings. In addition, specialists in the art will understand that various modifications and changes in the present invention without departing from the spirits or scope of the present invention. Thus, it is understood that the present invention includes modifications and changes of the present invention provided that they are included in the scope of the attached claims and their equivalents.

Will be given a detailed description of the discharge device and the cooling device containing a discharge device, in accordance with the embodiment with reference to the accompanying drawings.

Below the device for processing the service, contains the heat pump, and the way to manage them in accordance with the present invention will be explained in more detail with Silkina accompanying drawings.

Figure 1 is a perspective view schematically illustrating the inner construction of the device for processing service in accordance with one embodiment of the present invention, and figure 2 is a top view of the device for processing service figure 1. Referring to figures 1 and 2, figure 1 depicts a drying machine for clothes as a device for the processing service. However, the present invention is not limited to the device for processing service and can be applied to any device for processing service for drying clothes by blowing hot air into the drum, for example, a washing machine having a drying function, etc. of a Device for processing service in accordance with the present invention includes a housing 100, which forms the appearance of a drying machine for clothes, and the drum 110, mounted rotatably in the housing. The drum is supported rotatably by a support (not shown) on the front and back sides.

Air suction channel 120, which forms part of the air inlet of the flow channel towards the inner part of the drum 110, is installed on the lower surface of the drum 110, and the end of the air suction channel 120 is connected to the rear end of the channel 122. Back channel 122 passes in the direction of up-down housing 100 between the air suction channel 120 and Baraba the MD 110, thus, applying the air passed through the air intake duct 120, the drum 110. Accordingly, the formed air suction flow channel through which air is supplied into the drum 110, by means of an air suction channel 120 and the rear channel 122.

The air fed through the air suction flow channel passes into the housing through the opening for suction of air (not shown)formed on the back surface or the lower surface of the body, and then moves in the air intake duct 120. For a given air flow to the air suction fan 185 is mounted on the end of the air suction channel 120. That is, the air inside the enclosure is served in the air intake duct 120 due to the rotation of the air suction fan 185. It can lower the pressure inside the enclosure, thus, causing the outside air to pass into the housing through the opening for suction of air.

The capacitor 130 is installed on the front side of the air suction fan (on the upstream side in the air flow channel). The capacitor 130 forms a heat pump in combination with the evaporator 135, the compressor 150 and the expansion device 160, which will be described below. One pipeline 134 refrigerant is in a zigzag form, and the plate is s 132 radiation mounted on the surface of the pipe 134 refrigerant. Since the air suction fan 185 is located on the downstream side from the condenser 130, the air intake air intake fan 185, performs heat exchange with the refrigerating agent through contact with the radiation plates of the capacitor 130. Then, air is supplied into the drum, having a fever. As the adjustable expansion device 160 uses linear expansion valve (LEV), the degree of opening of which is controlled by an electric signal.

The heater 170 is installed in the rear channel 122 for additional heating of the air, not heated by the condenser 103. The heater 170 may be installed on the air suction channel 120. This air is heated while passing through the condenser 130 and the heater is supplied to the drum in the form of hot air and then used for drying object to be dried and placed in the drum.

Then, the hot air produced in the air outlet channel 140 of the exhaust air fan 180, located under the drum 110, and then carries out heat exchange with the low temperature cooling agent passing through the interior of the evaporator 135 located at the end of the air exhaust channel 140. Then, the air is produced on the outer side of the housing 100. Due to these processes Teploobmen is and the air is produced on the outer side of the housing 100, having a lowered temperature and humidity. Part of the heat energy produced air is transferred to the cooling agent through the evaporator 135 and resubmitted the intake air through the condenser. That is, the heat energy produced air is accumulated for re-use to generate hot air. This can reduce the amount of energy consumption.

If enough heat is not received from the evaporator 135, part of the refrigerant released from the evaporator is fed to the compressor 150 in the liquid state. When the supply of liquid refrigerant to the compressor 150, the compressor may be damaged or may have decreased energy efficiency. Accordingly, the temperature difference between the refrigerant passing through the evaporator 135, is defined for indirect validation of the dry condition of the refrigerating agent. In a preferred embodiment, the first sensor 136 temperature is located on the inlet side of the evaporator 135 and the second sensor 137 temperature is located on the intake side of the compressor (see figure 2).

If the refrigerating agent receives enough heat from the evaporator 135, the temperature difference between the refrigerant between the front and rear sides of the evaporator 135, i.e. T2-T1 (when it is assumed that the temperature on the inlet side of the evaporator is T1 and the temp is the temperature on the intake side of the compressor 150 is T2), has a value greater than the specified value (the first value). The first value is defined as the minimum value, when the heat pump system is working properly.

On the other hand, if the refrigerating agent receives an excessive amount of heat from the evaporator 135, the temperature difference (T2-T1) is not in the normal range. In this case, the value (T2-T1) exceeds the second value, defined as the maximum value, when the heat pump system is working properly.

When the value of (T2-T1) is not in the normal range between the first value and the second value, the degree of opening of the adjustable expansion device 160 is adjusted for changes in the flow rate of the cooling agent and change the value (T2-T1).

Figure 3 - block diagram schematically showing the configuration of the controller device 200 for processing service figure 1. Referring to figure 3, the controller 200 that is located in any position of the body 100 is electrically connected to two sensors 136 and 137 determining the temperature and receives the signal definitions, thus testing whether normal heat pump system based on the value (T2-T1). If it is determined that the heat pump system is not functioning normally, the degree of opening of the adjustable expansion device 160 is adjusted to bring the heat pump system is we have to set the mode.

The reference position 138 denotes a humidity sensor installed in the exhaust air channel through which air discharged from the drum. Operation of the sensor 138 humidity will be described below.

With reference to figure 4 will be described the processes regulating the opening degree of the adjustable expansion device 160 by the controller. Referring to figure 4, at the start of the drying process, the controller 200 includes an adjustable expansion device 160 and then sets the pulse signal applied to the adjustable expansion device 160 that is equal to a. Here, the value a denotes the value corresponding to half or less than the number of pulses filed for an adjustable expansion device when the adjustable expansion device 160 as open, which is set to 80 in the preferred embodiment. The reason why the degree of opening of the adjustable expansion device 160 is first reduced, is to prevent the flow of a large quantity of liquid refrigerant remaining in the condenser or the evaporator during the previous drying process, the compressor 150.

Then, it is checked, working or not, the compressor 150. If it is determined that the compressor 150 is idle, the valve is adjustable expansion device is adopted in a state, in which it is located. On the other hand, if it is determined that the compressor is in operating condition, the degree of opening of the adjustable expansion device maximum increases. For this purpose the maximum number of pulses of the signal applied to the adjustable expansion device, is set equal to 460. Here, the maximum number of pulses is only indicative and may vary according to the type and characteristics of the expansion device.

After setting the maximum number of pulses T1 and T2 are determined by the two temperature sensors. Then T2-T1 is calculated based on a specific T1 and T2. If the value of (T2-T1) is between the predetermined first value and a specified second value, the controller determines that the heat pump system is in steady state. Then, the controller again determines the values of T1 and T2.

If the temperature difference is less than the first value, this means that a sufficient amount of heat is not given from the evaporator, and thus, refrigerant is supplied to the compressor in a liquid state. Accordingly, the degree of opening of the adjustable expansion device is reduced to reduce the flow rate of the cooling agent. Here, the controller checks the number of pulses of the signal podano is on the adjustable expansion device, and otherwise sets the width of reducing the opening degree of the adjustable expansion device in accordance with an established number of pulses.

More specifically, the controller divides the range between the maximum value (460) and minimum value (40) the number of pulses of an adjustable expansion device into the following 4 parts:

First part: 300 ~ 460,

Second part: 200 ~ 300,

Third part: 100 ~ 200,

Fourth part: 400 ~ 100.

Produced by the air released from the drum, contains a large amount of moisture during the initial stage of the drying process. Accordingly, thermal energy in the form of latent heat above thermal energy in the form of sensible heat. This can cause difculty in the implementation of heat exchange. When it is determined that the value (T2-T1) is less than the first value during the initial stage of the drying process, the adjustable expansion device must have a large width reducing the degree of opening, so that the status parameter of the cooling agent can be adjusted to an appropriate level. On the other hand, when the process of drying, the amount of moisture contained in the produced air becomes small. As a result, the amount of energy in the form of sensible heat increases. In this case, the width of the less open the I adjustable expansion device relative to the narrowed for the regulation of the status parameter of the cooling agent to a sufficient level.

From the point of view changes the state parameter of the cooling agent is mainly to increase the width of reducing the degree of opening. However, if the flow rate of refrigerant is reduced, it is not preferable from the viewpoint of energy efficiency, since the amount of heat recovered by the evaporator, is also reduced. Accordingly, to quickly change the status parameter of the cooling agent in the state in which the width reduction and energy efficiency is minimized, the width of the reduction in the flow rate of the cooling agent should be determined on the basis of proven speed of implementation (implementation rate) of the drying process.

5 is a curve changes the opening degree of the adjustable expansion device in accordance with the speed of the drying process. As shown in figure 5, the first part of the four parts correspond to the initial stage of the drying process and the fourth part corresponds to the final stage of the drying process. Therefore, in the first part of the width reduction of the pulse signal applied to the adjustable expansion device is set to 30, a relatively large value. However, when the process of drying the width reduction of the pulse is reduced and set to 2.

After less open the Oia adjustable expansion device controller repeatedly determines the values of T1 and T2.

When the value of (T2-T1) exceeds the second value, the number of pulses of the signal applied to the adjustable expansion device is increased, as shown in figure 5.

When the value of (T2-T1) is not in the normal range, despite the regulation of the degree of opening of the adjustable expansion device determined that problems arose in the device. Accordingly, an abnormal condition of the device is reported to the user via the display 210, located on the control panel (not shown).

Alternatively, the heater pan to heat the oil may be located on the compressor. The heater tray heater means for heating the oil contained in the compressor, and performed to obtain a viscosity suitable for operation of the compressor due to the heating of the oil during the initial stage of the compressor. To control the operation of the heater pallet third temperature sensor can be installed on the discharge side of the compressor to determine the temperature of the cooling agent, coming out of the compressor. On the basis of a certain temperature, the operation of the heater pan can be controlled.

The operating condition of the heater pan can influence external conditions of premises, equipped with a device for processing service. For the NGOs, temperature measurement can be carried out taking into account external conditions. This can be additionally equipped with an additional temperature sensor for measuring the outside temperature, and the values measured by the first to third temperature sensors, can be properly processed and used to control the device.

The drying process may be determined on the basis of the humidity of the output air that is released from the drum, not on the basis of the opening degree of the adjustable expansion device. The sensor 138 humidity is used for measuring the humidity of the air released from the drum, thus testing the speed of the drying process. Range humidity of the output air during the drying process can be divided into 4 parts, and each part can be set with different width reduction of the pulse.

Or the sensors 136 and 137 temperature, or a sensor 138 humidity can be set, or both of them can be installed. In the latter case, the temperature sensors can be used to check the speed of carrying out the drying process, the moisture sensor can be used only when the temperature sensor is not working properly. Alternatively, a temperature sensor and a humidity sensor as a whole can be used to check the speed of implementation is tvline drying process, respectively. After comparing the results obtained with the appropriate use of two sensors, each with a different degree of opening of the adjustable expansion device can be adjusted on the basis of the comparison result.
