Description

one

The invention relates to refrigeration, and the design refers to the design of refrigerators, primarily for domestic use.

Coolant fridge, which includes a cooled chamber with an evaporator, a low-temperature compartment formed by the evaporator, a non-rotary tube connecting the evaporators, and a compression system of the refrigeration system with a canneline tube.

Odiaco, in a known refrigerator, there is an insignificant temperature difference between the inventors, which leads to a loss of cold when the cooling chamber is cooled and the power consumption is excessive.

The purpose of the invention is to accelerate the thawing of the evaporator of the cooled chamber during the non-working period of the cycle, to increase the efficiency of the refrigerator and heat exchange.

For this purpose, in the refrigerator, a capillary tube is located along the overflow tube in close proximity to it with the formation of a regenerative heat exchanger, and it is advisable to place the capillary tube inside a non-return tube.

In addition, the regenerative heat exchanger can take the form of a siphon with a hydraulic lock and be installed above the evaporator of the chamber to be cooled, and the upper part of the latter is made like;

FIG. 1 shows schematically the proposed refrigerator, a cross-section; on

FIG. 2 - the same, rear view; in fig. 3 is a schematic diagram of the supply of refrigerants to the evaporators; in fig. 4 shows a second variant of the isioliepi node I in FIG. 3. The refrigerator contains a cooled chamber 1 with an evaporator 2 and low blood;

investment 3 formed by evaporator 4 and

separated from the chamber 1 insulating

partition 5 and the same door 6.

Refrigerated temperature

It is provided by a compression refrigeration system including a compressor 7, a condenser 8, a zeolite cartridge 9 and a regenerative heat exchange 10 formed by a suction tube 11 and a capillary tube

12.

The evaporators 2 and 4 are connected by an overflow pipe 14, this capillary tube 12 is located along the deadly tube 14 in close proximity to it, forming

a second regenerative heat exchanger 15, naming a siphon with a water seal 16. In addition, in the evaporator 2, the upper part is inclined to increase its efficiency by increasing the wetting surface with boiling refrigerant

and ora.voyai in this part of the zone of the 1Up temperature, in which the tank 17 is installed for the short-term storage of fresh / KCii fish or common meat. The refrigerator operates as follows.

The Kompressor 7 injects the popular refrigerant into the condenser 8. The liquefied refrigerant from the condenser 8 through the zeolite natron 9 enters the charger 4.

Since there is little Tenla required for a complete isnary liquid refrigerant, a liquid-liquid mixture with a significant content of liquid enters the overflow tube 14, which is sent through the regenerative heat exchanger 15 to the evaporator 2, where the total evaporation of the refrigerant occurs. From the charger 2, the refrigerant returns to the compressor 7 through the regenerative heat exchanger 10. The regenerative heat exchanger 15 formed by the capillary tube 12 and the overflow tube 14, placed, for example, in the type of pipe in the pipe, is used to heat the steam mixture of the evaporator 4, which overflows the evaporator 4 to the evaporator 2 , due to the tenla of the liquid refrigerant entering through the capillary tube 12 from the condenser 8 to the safety terminal 4.

Due to this, evaporator 2 in otlnchy from the evaporator 4 doesn’t seem to have a liquid-liquid mixture with a low liquid content, and since the tenant load of the evaporator 2 is greater than the thermal load of the evaporator 4, the steam mixture does not only turn into steam, but also overheat. Consequently, the temperature of the evaporator 2 is significantly higher than the temperature of the evaporator 4, and therefore, during the non-working period of the cycle, significantly less heat and time is required for its thawing.

The hydraulic shutter 16 of the regenerative heat exchanger 15 helps to maintain the low temperature on the evaporator 4 during the off-peak period, when the heater 2 thaws.

In addition, the liquid refrigerant supplied through the capillary tube 12 to the evaporator 4,

5 is subjected to sub-cooling parozhidkostpoy boiling mixture in the regenerative heat exchanger 15 and the liquid refrigerant in the water seal 16. As regeneratnvnom tenloobmenni0 ke 15 capillary tube 12 is in heat exchange relationship with the boiling liquid but not neregretym Harom as in regenerative tenloobmeiiike 10, the efficiency of tenlobmena higher.
