The technical field to which the invention relates.

The present invention relates to a method of regulating the temperature of hot water in the hot water for low water consumption, which allows you to apply hot water to the required temperature, even if the flow rate of consumption of hot water in the hot water supply is negligible.

The level of technology

Typically, hot water supply system (hereinafter "water heater provides hot water to the user and adjusts its temperature at the desired temperature due to the fact that after flow detection and flow measurement of the incoming water is included a heating device (hereinafter referred to as "burner"), after which the heat exchanger is transferred from the burner to the water arriving at the water heater. However, the known heaters don't allow you to adjust the temperature of the hot water in cases where the amount of hot water is low enough that the detection of flow and water metering is difficult, or when the flow rate of consumption of hot water is small so it is difficult to ensure the ignition of the burner, even if you can measure flow.

In particular, water heaters traditional design burner ignition and temperature control of hot water at the required temperature is tours (hereinafter referred to as "set temperature") is only when the flow rate of consumption of hot water is approximately 2-3 l/min or more. In such heaters flow sensor that measures the amount of hot water, designed for a range of commonly used values of consumption. As a result, the specified accuracy of the sensor is degraded when the flow rate is very small and amounts to 2-3 l/min or less. Moreover, even if the temperature of the hot water regulate due to minimal thermal power of the burner in accordance with the capacity of the water heater, hot water can be served at a temperature above the set temperature, when the temperature of incoming water is slightly increased, and the amount of hot water is very small.

Thus, manufacturers of water heaters set the minimum rate at which it is possible to regulate the temperature of hot water. For example, by a flow sensor to measure the amount of hot water, and when the specified number is equal to 2.5 l/min or more, carry out the regulation of thermal power of the burner due to the operation of the water heater. Usually this value is called the "operational expenditure", and it should indicate for each heater. Thus, these heaters do not work when the number of the adolescent is my hot water is less maintenance. For example, when the flow rate of consumption of hot water is less than 2.5 l/min, the heater does not work and does not provide temperature control of hot water.

In the heater, known from the prior art and shown in figure 1, when water enters the heater through the inlet 1, sensor 2 flow measures the flow of water consumed, and the sensor 3 temperature determines the temperature of the incoming water. Comparing the measured temperature with the set, carry out the ignition of the burner for supplying hot water user defined temperature. The hot water temperature regulate by heat transfer from the burner to the heat exchanger 4.

Despite the fact that the values of the operational flow of water heaters different from different manufacturers, they are approximately 2-3 l/min

Disclosure of inventions

The disadvantages of the known solutions

As described above, when the amount of water being less operating costs, the value measured by sensor 2 flow is less than the value of operating costs, and the burner is not included.

When the user takes a shower, the water flow may be different depending on user habits, but, as a rule, it is roughly 8 to 10 l/min using a single valve for hot water. At low d is the water pressure at the inlet or in too small quantity of water consumed, for example, when the user is shaving, consumption, consumption of hot water is lower operating costs, as a result, the heater does not work and does not provide hot water.

Tasks inventions

In view of the foregoing, the present invention is to provide a method of regulating the temperature of hot water at a low flow rate of consumption of hot water, which allows you to adjust the temperature of the hot water, due to the actuation of the heater even in low water pressure at the inlet of the water heater, or when the flow of hot water used by the user is less than the operational flow of the water heater.

Technical result provided by the invention

According to the present invention, when the measured hot water consumption is below the operational flow of the water heater include using the controller, the circulation regime with preheating at which water under the action of the pump circulates in the heater circuit, resulting in possible to control the temperature of hot water even at low inlet water pressure, or when the flow of hot water used by the user is less than the operating costs of traditional water heaters.

Option of carrying out the invention

Following is a detailed description of what the design and principle of operation of preferred embodiments of the present invention with reference to the accompanying drawings. It should be noted that the same elements in different drawings are denoted by essentially the same numbers of items.

Figure 2 presents the diagram of a water heater according to the first embodiment of the present invention. Figure 3 presents a diagram of the heater in accordance with a second embodiment of the present invention. Figure 4 shows the circuit of the water in the water heater according to the first embodiment of the present invention, in the mode preheating. Figure 5 shows the circuit of the water in the water heater according to the first embodiment of the present invention, in the process of consumption of hot water.

As shown in figure 2, the heater 100 according to one variant of the present invention includes a flow sensor 11 that is designed to measure the flow of incoming water, the sensor 12, the temperature of the incoming water, designed to measure the temperature of the water received through the inlet 10, the heat exchanger 13, the transmitting burner heat incoming water to heat to the set temperature, the temperature sensor 14 facing the water, designed to measure the temperature of the water passing through the heat exchanger, the tank 15 to the water in which stored water, passed through heat exchanger 13, the controller 16 of consumption, which is designed to adjust the flow of hot water, pump 17, mounted on the tube 24, the connection is managing the first point 21 branches, available on the pipe on the output side 20, with the second branch point 22, the pipe from the inlet 10, the check valve 18 prevents the backflow, and the controller 30, is equipped with a device 31 input intended for the user to enter the desired parameters.

As a rule, in the process using hot water, the controller 30 via the flow sensor 11 detects the amount of hot water and by means of the temperature sensor 12 measures the temperature of the incoming water. Further, by comparing the measured water temperature with the set, calculate thermal capacity of the burner required to heat the incoming water heater to the set temperature depending on the amount of hot water used at the current time. And, thus, carry out the temperature control of hot water. The temperature of the water passing through the heat exchanger 13, is measured by a sensor 14, the temperature of the outgoing water. When the measured leaving water temperature differs from the set temperature control of hot water is carried out by adjustment of thermal capacity of the burner. Hot water, passed through heat exchanger 13, is stored in the tank 15 to the water, and then served to the user via the output 20.

Despite the fact that the heater agreement is but the above-described variant of the invention the tank 15 for water is located behind the heat exchanger 13, it can also be placed and before the heat exchanger 13 as in the second embodiment of the invention, is shown in figure 3

The greater the volume of the tank 15 to the water, the easier it is to respond to the increase/decrease of the number used by the user of hot water. However, increasing the volume of the tank 15 for water leads to an increase in the total volume of the heater, thus, there are restrictions on the volume of the water tank. Generally, the volume of water tanks ranging from 2 to 3 liters

When the user ceases to use the hot water or when the flow rate of consumption of hot water is very low, for example, when the flow of hot water measured by the flow sensor 11 is less than 2.5 l/min, this indicates that the user has stopped using hot water, resulting in the burner shuts off. The yield of 20 closes and turns on the circulation with preheating at which hot water is pumped by pump 17, circulates in the internal contour connecting the first point 21 of the branch, the second branch point 22 and the heat exchanger 13. The specified path is indicated in figure 4 with a solid line.

In circulation mode with pre-heating controller 30 via the sensor 14 leaving water temperature determines the temperature of the circulating water, ensure the ignition of the burner, when the measured temperature is and will be 5C below the set user preheating temperature hot water (hereinafter referred to as "temperature mode pre-heating hot water"), turns off the burner when the temperature measured by sensor 14 leaving water temperature 5C higher than the temperature of the preliminary heating of hot water (hereinafter referred to as "temperature mode pre-heating hot water"). Then, the controller 30 includes a pump 17 for a predetermined period of time (for example, 10 seconds) and disables it.

Then, at exactly the lowering of the temperature measured by sensor 14 leaving water temperature, relative to the set temperature, you must turn on the burner and at exactly the temperature you want to disable the burner, namely, what is the temperature mode pre-heating of hot water and temperature mode pre-heating of hot water depends on the design of the system.

In the above method, the heater is always circulates hot water having a temperature close to the set, even with low water pressure at the inlet or at a very low consumption consumption of hot water, not exceeding the operational flow of the water heater, for example, when shaving, as a result, this allows you to always give the user the hot water necessary temperature. In addition, you can provide quick delivery of hot water set temperature is even, if after this, the user will again begin to use hot water. Moreover, due to the constant circulation of hot water in the circulation with preheating don't freeze and break the pipes of the heater when the temperature of outside air in the winter time, which is an additional advantage of the present invention.

The user can arbitrarily through the input device 31 to set the run time mode of circulation with preheating. For example, the user can set the time so that the circulation with the preliminary heating is carried out continuously for 24 hours. Or the user can set the execution mode of circulation with preheating, for example, from 6.00 to 24.00, except for the time of sleep.

If the user often uses hot water at low flow rate, which depends on the conditions of use hot water or from the habits of the user, the temperature mode pre-heating and temperature mode pre-heating of hot water can be adjusted, for example, within 2C from the set temperature due to the mode of low consumption of water through the device 31 input connected to the controller 30.

That is, after the user is tel through the input device 31 has set the mode of low consumption of hot water, the pump 17 of the heater 100 pumps the water inside the water heater. And when the temperature recorded by the sensor 14 of the leaving water temperature will be 2C lower than the set, the burner will be ignited to raise the temperature of the water in the water heater, and when the temperature measured by the temperature sensor 14 facing the water at 2C exceeds the set temperature, the burner will shut down. Then the pump 17 will work within a predefined period of time and then turns off. Further, when the temperature of the hot water outlet as a result of its continuous consumption at a low flow rate is gradually reduced, and will be 2C below the set temperature, the burner will again ignite, and by operation of the pump, the outlet temperature will be maintained within 2C from the set temperature. The user through the device 31 is input simultaneously with low hot water consumption can also set the temperature mode pre-heating and temperature mode pre-heating of hot water. Thus, to provide hot water even when the consumption of hot water is at low flow.

In case of resumption of use of hot water by the user (the path of movement of water in this case is provided with a bold line on figure 5) water, received inside through the inlet 10, is heated in heat exchanger 13 and passing through the tank 15 for water, is delivered to the user via the output 20.

When the user opens the valve at the outlet 20, to use hot water, the water reached the first point 21 branches, under the action of the pressure difference can be completely drained through the outlet 20, as a result of internal circulation, shown in figure 4, is terminated. The flow sensor 11 is installed on the pipe connecting the inlet 10 with a heat exchanger 13, as a result, when the specified sensor detects the flow of water beyond the operational flow of the water heater, the detected signal is sent to the controller 30, which includes a burner for regulating the temperature in the heat exchanger 13.

Figure 6 presents a flowchart illustrating a method of regulating the temperature of hot water in the proposed water heater with a low consumption power consumption of hot water.

First, using the controller 30 determines, not less than if measured by the sensor 11 of the consumption amount of the user's hot water maintenance water heater, for example, values of 2.5 l/min (S10).

If the amount of hot water below 2.5 l/min, then the burner shuts off and turns on the pump 17 (S20). If the amount of hot water is greater than 2.5 l/min, t is the temperature of the hot water regulate by adjusting thermal power of the burner in accordance with the known method (S21).

Then determine whether the user had selected the mode of low consumption of hot water (S30).

If the mode of low consumption of hot water is installed, using the controller, set the temperature mode pre-heating of hot water at 2C above the set temperature and the temperature mode pre-heating of hot water by 2C below the set temperature (S40).

If the mode of low consumption of hot water is not installed, using the controller, for example, set the temperature mode pre-heating of hot water for 5C above the set temperature and the temperature mode pre-heating of hot water by 5C below the set temperature (S41).

After that determine is equal to or lower than the hot water temperature is measured by a sensor 14, the temperature leaving water temperature mode pre-heating of hot water (S50). If the measured temperature is equal to or lower than the temperature mode pre-heating of hot water, for regulating the amount of heat to ignite the burner and includes a pump (S60). If the measured temperature is above the temperature mode pre-heating of hot water, then returns to step S50, and the leaving water temperature is measured SN the VA.

Next, determine equal or higher than the hot water temperature is measured by a sensor 14, the temperature leaving water temperature mode pre-heating of hot water (S70). If the measured temperature is equal to or higher than the temperature mode pre-heating of hot water is off of the burner and the inclusion of the timer pump (S80). If the measured temperature is below the temperature mode pre-heating of hot water, then returns to the step S70.

Then determine to expire or 10 seconds on the timer pump (S90). After 10 seconds, set the timer, pump off (S100). Then return to the step S50.

In the case of the proposed method with the consumption of hot water at low flow rates, it is possible to eliminate the shortcomings of heaters known in the art and is not providing hot water due to the failure. Due to the fact that the water heater according to the above-described version of the present invention provides a hot water set temperature at very low flow, to regulate the temperature of the hot water heater on the temperature level set by the user, regardless of the settings of the water heater or p is of epicac user.
