The invention relates to a cooling device (1) two-door type having a chamber for fresh food and Luggage for frozen food products, equipped stores energy elements.

In the modern technical level there are many decisions related to cooling devices, which contain two separate and independent access cameras: one for fresh food and the other for frozen food. In particular, the market cooling devices there are two types of cooling devices, with offices freezers, available via special closing system, such as a door, and therefore the user does not need to open the camera for fresh food, to gain access to the Department containing the frozen foods. Therefore, in this sense camera for frozen food is independent from the camera for fresh food. Two such types of cooling devices are so-called "two-door" and "combined" cooling device.

Combined cooling devices typically differ in that they have a large branch of the freezer, in General having a volume greater than 70/80 litres.

Due to a number of technical and aesthetic FA is tori, including large Luggage for frozen food products such types of cooling devices is located at the bottom of the device and is made of plastic material. Therefore, in the combined cooling devices according to the prior art camera for frozen food consists of a casing made of plastic material, is inserted into the shaped chair supporting structure, which supports the camera for fresh food.

The plastic casing used in combined cooling device for a camera for frozen food products, is designed to provide the ability to insert a range of elements, including drawers, shelves and the device of the evaporator.

In cooling devices, known as "two-door" cooling, camera for frozen food is at the top of the device and has a reduced size while in the "combined" cooling device chamber volume for frozen food can be even 40-50% of the volume of the chamber for fresh food, "two-door" cooling device chamber volume for frozen food in most cases is less than 30% of the chamber volume to fresh the food; usually the camera for a frozen food has a volume less than 60 litres. In "two-door" cooling devices smaller chamber volume for frozen food provides the ability to make it from aluminium. Inside the chamber for frozen food has several shelves, which can be a metal mesh or solid shelves, made of plastic or glass material. As will become apparent later, aluminum construction has the advantage of making possible the passage of the evaporator around the whole structure, thus remaining within the walls of the chamber for frozen food.

All known solutions of the cooling devices food products are cooled in a known manner by means of the cooling system that contains the motor which drives the compressor, the task of which is to compress the gas, in General R134a or R600a, which reaches a high pressure, and hold it in a gaseous state and sent to the condenser where it condenses and becomes a high pressure fluid; through the coil located on the back wall of the cooling device, the fluid dissipates its heat and cools down. Subsequently, the liquid refrigerant of high pressure passes through the EXT is satisfactory device.

The expansion device is a node that is installed between the condenser and evaporator of the cooling device, and has the function to ensure a rapid pressure drop.

Therefore, the expansion device acts as a differential pressure. The presence of differential pressure in the cooling cycle is very important because it causes a change in the boiling point of the gas. Without this pressure fluctuations of the liquid refrigerant does not significantly reduce its temperature, reaching several tens of degrees below zero, and therefore, the cooling will not occur; the system would be only a simple container of a cooling element, for example, R134a or R600a.

The refrigerant exiting the expansion device, generally consisting of a small tube, called a "capillary", then fed into the coil, called the evaporator, which takes place inside the walls of the cooling unit to absorb heat from the interior of the chamber to be cooled. Having absorbed the heat of the liquid refrigerant evaporates and is returned to a gaseous state. This provides the opportunity to receive the cooling process inside the cooling unit.

After that, the gas is fed into the compressor and the cycle begins again.

Depending on the type of cooling unit evaporator can be the careless two different and complementary ways.

In "two-door" cooling devices according to the modern technical level, the evaporator is made of two parts, one of which is connected with camera for frozen food and the other is connected with the chamber for fresh food, and is installed between the outer part of the cooling unit and cameras; then between the two walls placed insulation foam. In particular, the evaporator completely surrounds the camera for frozen food.

In the "combined" cooling devices, in which the camera for frozen food products is very large, and the design of the camera is made of plastic material, the cooling system contains a device evaporator: the evaporator, which is in the "door" of the cooling chambers is a coil located outside the chamber to be cooled, in the "combined" cooling devices provided through its own continuous tubular structure located in the form of shelves inside the chamber. Solution devices evaporators are known from the patents GB 2133518 and GB 2133519.

Increasing requirements for energy efficiency of cooling devices has led to the definition of the classes of energy consumption (denoted by letter of the alphabet from A++ to F, in order of increasing consumption), which are useful the mi as a guarantee for the buyer, and at the same time has led to the fact that manufacturers pay more attention to the aspect of energy consumption.

In this context, and being the best solution for the already well-entrenched system of cooling of the schema that contains the compressor, condenser, expansion device and evaporator), attention has shifted to the search for solutions that provide better insulation and more efficient compressors driven by a motor. However, such decisions involve large costs of research, and achieved improvements are often not very noticeable and do not have adequate payback.

The present invention is to resolve the problems associated with known cooling devices, by providing the cooling device, known as a device "two-door" type, which provides the ability to store electrical energy and superior performance.

An additional object of the present invention is to provide a solution to the problems of the prior art, and the solution is both cost-effective and efficient.

The task is achieved through the cooling unit two-door type, containing

- cooling system,

camera (3) for frozen food,

moreover, the cooling system includes at least two evaporator(5, 14, 31, 32), the evaporator, a cooling chamber for frozen food, covers the specified camera for frozen food products, characterized in that at least one section (5) of the evaporator (14, 31), the cooling chamber (3) for frozen food, is held inside the chamber (3) for frozen food.

Preferably the camera for a frozen food has a volume less than 60 litres and has a volume of less than 30% (thirty percent) of the volume of the chamber for fresh food has such a size that provides the ability to insert a dividing shelf for placement of food, and has such a size that provides the ability to insert only one dividing shelf.

In addition, preferably the height of the spaces defined by a dividing shelf inside the chamber for frozen food, is to provide the opportunity to place food products, in particular, not less than 10 cm

The shelf is preferably formed only section of the evaporator, passing inside the cell for frozen food products, and has a bearing surface for food on the bottom side of which is located the evaporator section, passing inside the chamber for frozen food.

Preferably the bearing surface for food products made from plastics material or glass.

Means for cooling preferably comprises an electromagnetic valve and two capillary related to the two chambers of the cooling device.

The solenoid valve is preferably controlled by an electronic thermostat and provides hydraulic switching between the two capillaries.

Additional objectives and advantages of the present invention will become apparent from the subsequent detailed description and the attached drawings, given as non-limiting example.

Figure 2 shows a transparent view of the cooling system options exercise of the cooling device in accordance with the invention.

Figure 3 shows a cooling system in accordance with the second embodiment of the cooling device according to the invention.

Figure 1 shows the "two-door" cooling device, indicated in General SS is Nochnoi position 1. The cooling device has two cameras (the camera (2) for fresh food and the camera (3) for frozen foods)that have access independently from each other through the relevant system (6, 7) closing.

Figure 1 system (6, 7) closing, such as the door shown in the open position to show the interior of the chamber (2) for fresh food and the camera (3) for frozen food.

For simplicity, not shown in figure 1 cooling system cooling unit completely. The system shown in figure 2 and 3 and additionally described below, contains the above-described known elements, i.e. the compressor, condenser, expansion device (in particular, one or more capillary tube) and one or more evaporator.

As has been described in detail in the beginning of the present description, "two-door" cooling device which is the subject of the invention contains a camera (3) for frozen food products, located in the upper part of the cooling device and having a smaller size; in particular, the size is such to be able to insert only one dividing shelf (4). It is assumed that in the preferred embodiment, the space (12, 13)defined by the shelf (4) inside the chamber (3) for frozen food products are up to the ciently large, to place food. Although they can vary from device to device depending on the technical and aesthetic requirements, usually space have a height of not less than 10 cm

As you can see, looking at these three drawing, camera (3) for frozen food contains additional section (5, 14) of the evaporator, i.e. the element of the system of internal cooling, in which the liquid refrigerant (e.g., R134a, R600a, freon).

According to the invention additional section (5, 14) evaporator passes outside of the camera for frozen food in and out of at least one of the walls, thus passing inside the chamber (3) for frozen food.

Therefore, according to the invention the cooling device (1) has an evaporator section, below referred to as "external evaporator" (14) and figures 1 and 2 indicated by the dotted line, which, as in the prior art, passes around the camera (3) for frozen foods and the camera (2) for fresh food, as well as another section of the evaporator, below referred to as "internal evaporator" (5) and indicated in figure 1 and 2 by the solid line, which runs inside the chamber (3) for frozen food.

In more detail, figure 2 shows a preferred implementation of the system ohlord is of the cooling device according to the invention: compressor (15) compresses the refrigerant (for example, freon or R134a or R600a), which is in a gaseous state in the condenser (16), where it condenses and cools.

When the refrigerant is in a liquid state, it passes through the filter (17), which traps any impurities present in the schema, and then passes through the capillary tube (20) before entering the evaporator.

The refrigerant passes into the evaporator, consisting of a system of tubes situated mainly in the form of a coil, passing mainly inside wall of the refrigeration device, and then returns to the compressor (15). This path from the capillary to the compressor cooling element in a liquid state absorbs heat and evaporates, thereby cooling the inner part of the cooling unit.

With reference to figure 2 it should be noted that, in addition to passing inside the walls of the cooling unit, the evaporator according to the invention also extends from point (18) of the walls of the chamber (3) for frozen food and takes place inside a chamber volume for frozen food. This open section of the evaporator (5), called "internal evaporator", comes back into the wall of the refrigeration device at the point (19) of the chamber (3) for frozen food. From this point the "internal evaporator" (5) again becomes "external evaporator" (14) and resumes its journey, hidden from HL is C, inside the walls of the cooling device (1) until the compressor (15). Unexpectedly, this technical solution has enabled the production of the cooling device, in which when the same volume of cooling food in the chamber (3) for frozen food occurs with conservation of energy: increase the cooling area actually allows the cooling system to absorb more calories from the camera for frozen food products, without the need to increase operating cycles of the system (i.e., periods of time during which the compressor is enabled), and therefore reduces the energy consumption without increasing the capacity of the compressor or improvement of elements of the isolate. In addition, the location of the internal evaporator" (5) so, in order to improve the cooling chamber (3) for frozen food cooling evaporative surface was moved inside the camera for frozen food.

So it was easier to understand, you should refer to the rules of thermodynamics: the cooling device (1) is a machine that takes the heat from the heat source (food inside the camera) and gives it to another heat source (cooling element)and in the external environment benefit is are work running the machine that takes energy from the electrical network. The quantity of heat (Q)that is exchanged between the two sources, in proportion to the area (S) of evaporation and the temperature difference between the two sources (Q=kS(T2-T1)). In the ideal case, according to the first law of thermodynamics the amount of heat (Q) must be equal to the energy (E)consumed from the electrical network, but in fact due to the different scattering between these two physical quantities have only proportionality.

From the above description it is clear that inside the cooling unit can be absorbed the same amount of heat (Q), if increases the area (S) of evaporation and decreases the temperature difference (T2-T1between the two heat sources; in other words, those calories can be absorbed from the inside of the camera for frozen food, if area increases evaporation and at the same time decreases the difference between the temperature T1the evaporator and the temperature T2food storage. Under ideal machine relative efficiency of the Carnot cycle, set n=(1-T1/T2), the closer the T1to T2the less energy is E=n*Q, which machine should consume from the electrical network. Therefore, it is clear that by increasing the area of ispar the deposits can reduce the consumption of the cooling device (1).

In accordance with the invention increase the evaporation area is possible due to "internal evaporator" (5), i.e. sections of the evaporator, which, in addition to embracing fully the chamber (3) for frozen food products while maintaining between the walls of the cooling unit and the external walls of the cells for fresh food (2) and/or frozen food (3), is also held inside the chamber (3) for frozen food.

Figure 3 shows the cooling system, i.e. a schematic diagram of the cooling system, the second variant implementation of the cooling unit two-door type according to the invention. The cooling unit is a two-door type has two cameras, namely the camera (3) for frozen foods and the camera (2) for fresh food placed through the respective evaporators 31 and 32.

The cooling system includes a compressor (15), upstream from which are consistently located the condenser (16), hot tube (33), the filter (17) and the three-way solenoid valve (34), which is controlled by the electronic relay (40) temperature; cooling system is divided into two schemes presented two capillaries, namely the capillary (35) a cooling chamber and a capillary tube (36) of the freezing chamber, connected to the electromagnetic valve (34), to the which can perform hydraulic switching between the two capillaries (35) and (36) so, so that they can alternately be powered from a compressor (15), depending on whether you want only the cooling chamber (3) for frozen food or and the camera (2) for fresh food, and the camera (3) for frozen food.

Both capillary (35) and (36) reverse cross tube (39) in the first heat exchanger (37), from which they emerge, following separate paths.

Capillary (35) a cooling chamber passes through the second heat exchanger (38) and then moves circulating inside the liquid refrigerant in the upper part of the evaporator (32) camera (2) for fresh food.

After going through the entire evaporator (32) camera (2) for fresh food liquid comes back and passes through the second heat exchanger (38), thus absorbing heat from the capillary (35) a cooling chamber, and then enters the evaporator chamber (31) for frozen food. In two-door cooling unit coil evaporator chamber (31) for frozen food products covers the entire outer surface (the section called "external evaporator") camera (3) for frozen food products and in accordance with the invention before the end of the path in the opposite tube (39) and returning to the compressor (15) also takes place inside the chamber (3) for frozen food section called "GNC is Rennie evaporator" (5)), as shown with reference to figure 2.

In contrast, the capillary tube (36) freezer goes right to the top of the evaporator chamber (31) for frozen food products, and therefore, without passing through the second heat exchanger (38).

The electronic control system of the refrigeration device in accordance with the shown in figure 3 of the embodiment is composed of the first temperature sensor (42)located in the chamber (2) for fresh food, which provides information about the temperature of the air in the chamber (2) for fresh food for electronic relays (40) temperature; similarly, the second temperature sensor (43) sends information about the temperature of the air in the chamber (3) for frozen foods in the same electronic relay (40) temperature.

Thus, the logic control electronic relay (40) temperature can, depending on the value read by the temperature sensors (42, 43), to solve from time to time, be cool if both cameras (2, 3) cascade or only the camera (3) for frozen food, sending a corresponding signal to the solenoid valve (34)which, in turn, switches the liquid refrigerant or capillary (35) of the refrigeration apparatus, or in the capillary tube (36) freezer.

Figure 3 also shows a third senses the positive element (41), located on the evaporator (32) camera (2) for fresh food and used for controlling the defrosting of the evaporator.

Two example case for cooling devices two-door type according to the invention provide for the conservation of energy because of higher evaporation area, obtained through the sections of the evaporator, passing inside the chamber for frozen food.

In a preferred embodiment, the section of the evaporator, passing and visible inside the chamber for frozen food ("internal evaporator" (5)), made in the form of a coil, straight sections which have long, almost corresponding to the depth of the chamber (3) for frozen food, and the loops of the coil are close enough to be used as a bearing surface for food. Therefore, the solution of this type can be used as a shelf inside the chamber for frozen food. According to a preferred variant implementation, shown in figures 1 and 2, the evaporator passes around the lateral walls (9), top wall (11) and bottom wall (10) of the camera for frozen food, considering that it comes from the rear wall (8) (i.e., the person who stands before a cooling device (1) and open the covers corresponding door (6) camera (3) for frozen food). After passing inside the chamber (3) for frozen food evaporator is again in the rear wall (8), passing inside the other walls of the chamber for frozen food and returning, as described in the compressor. However, for the present invention it does not matter, does "internal evaporator" (5) from rear wall (8) or from any other wall (9, 10, 11). However, positive that its shape allows it to be used as a shelf.

It is also clear that those skilled in the art, it is possible to perform other modifications of the present invention; for example, to get the best result from the point of view of aesthetics, easy to use plastic or glass shelf, having inner evaporator" (5) on the bottom shelf. Thus, it is possible to retain the advantage of conservation of energy, offer a larger area of evaporation relative to the prior art, but bearing surface can be improved, and from an aesthetic and technical point of view: in fact, the food will not be based directly on the evaporator, and easy-to-clean shelf.

FIELD: transmission of thermal energy to vacuum dehydration and drying machines, vacuum driers, evaporation machines and low-temperature dehydration of materials; reworking and utilization of wastes of poultry farms and pig-breeding farms; food-processing, medical and microbiological industries.

SUBSTANCE: proposed method includes loading the staring material, evacuation of chamber to pressure below atmospheric, mixing the starting material, collection, drainage and removal of condensate, conductive supply of heat to starting material at simultaneous heating it within temperature range whose low level is limited by water evaporation temperature at working pressure in technological space and upper level is limited by conditions ensuring avoidance of losses of useful properties of starting material and destruction of living cells which is necessary for retaining proper properties of final product. The process is completed by discharge of dehydrated product. Thermal energy of water steam released in the course of dehydration of starting material in vacuum chamber is returned to heating system of starting material due to compression of steam to pressure not below atmospheric, after which compressed steam is delivered to hermetic cavities of technological heat exchanger-evaporator unit where starting material is kept. Superheated steam is condensed inside unit and thermal energy released at this is transferred to material being dehydrated which moves over surface of unit. Condensate is continuously drained from hermetic cavities of heat exchanger-evaporator via pipe line connected to heat exchanger which is used for delivery of cold starting material to vacuum chamber. Thermal energy of condensate is transmitted to cold starting material. Device proposed for realization of this method includes vacuum chamber where technological heat exchanger-evaporator unit is mounted , loading/unloading system, starting material heating system, chamber evacuation system, condensate receiver; it is additionally provided with compressor connected with collector through which used hot water-and-steam mixture is discharged into technological heat exchanger-evaporator unit and then to heat exchanger used for heating the starting material for delivery of it to loading system.

EFFECT: reduction of heat losses.
