The locking claian (K) K) is installed in front of the additional AND, which is equipped with an end-arsenal chamber 11 at the outlet. As a result of connecting additional AND 7 to the chamber 11, the liquid refrigerant enters the gaseous phase in both the freezing chamber and AND 8 the refrigerating chamber enters only the gaseous refrigerant, which leads to a slow warming of the cooling chamber. When And 8 warms up to the t-ry, which provides full defrost of the snow coat, the thermostat closes K 10. When the refrigeration unit is operating in continuous mode, the thermostat opens K 10 when And 8 reaches the set temperature, which leads to complete boiling of the refrigerant in basically and fill in, And in the chamber 11.

Description

one

The invention relates to refrigeration engineering, in particular, to the design of refrigeration units for two-chamber refrigerators.

The purpose of the invention is to reduce consumption

energy.

The drawing schematically depicts the proposed cooling unit for a two-compartment refrigerator.

The refrigeration unit contains compressor I, condenser 2 filter booster 3, cannel tube 4, main freezer freezer consisting of .5 and 6 sections, refill; 1 evaporator 7 connected in parallel with section 6, isch.ch 8 refrigerating chamber and otsasy-vayun1, iy pipe 9. Before the additional evaporator 7, valve 10 is installed, and after the additional evaporator - chamber 11 before the evaporator (docker). The thermostat 12 serves to control the operation of the compressor depending on the temperature in the frost; | the main chamber, and the thermostat 13 to control the operation of the boiler 10 depending on the temperature in the refrigerating chamber. Switch 14 is used to set the compressor to operate in the freezing mode.

The refrigeration unit works in the following manner.

When operating in cyclical mode (storage mode); 1 volt | t from compressor 1 enters condenser 2. where it condenses. Then the liquid refrigerant passes through the filter eupstell 3 and is throttled through the capillary tube 4 in the isnarite; the first frost; the first 1 of the chamber, the state of sections 5 and 6, where it boils, has a good effect. Then the vapor-liquid mixture of the HoCa hell gate mixture enters the psiaryte. Gaseous refrigerant through suction pipe 9 of nostunat to compressor I. Upon reaching isnarite, 1 of 8 of ho.

the chamber starts to drop sharply due to the increased working surface of the freezer evaporator. When the evaporator m of the freezer (air of the freezing chamber) reaches a certain thermal profile, the thermostat 12 turns off the space heater 1. The unit does not work until the freezing evaporator reaches the required thermal temperature. Then the thermostat 12- turns on the compressor 1 and the unit operates cyclically, maintaining the set temperature in the freezer. Meanwhile, the evaporator 8 of the refrigerating chamber is heated to a temperature that ensures full defrosting of the snow bar, and the thermostat 13 closes the valve 10. The evaporator 8 begins to receive a liquid refrigerant, cooling the cooling chamber. Further, the unit operates periodically with shutdown of compressor 1 of thermore1 and ultor 12, gradually cooling the refrigerating chamber. When the evaporator 8 reaches the cooling chamber of the temperature of operation of the thermostat 13, the valve 10 is opened and the cycle of operation of the unit is repeated.

During the operation of the hot-duty unit in uninterrupted 1st mode (freezing mode), switch 14 turns on compressor I in continuous operation. The thermostat 13 opens the valve 10 upon reaching the evaporator 8 of the cooling chamber at a given temperature, which leads to a complete removal of the refrigerant in the evaporators of the freezing chamber (5, 6, 7) and the chamber 1 1. At the same time, the temperature of the evaporator 8 is gradually increased, and the noc / ie thawing the thermostat 13 closes the clan 10. The liquid refrigerant again starts to drop into the evaporator 8 X 0.1 one and the other.
