Embodiment Construction

[0011] see figure 1 , the present embodiment consists of a compressor 1, a condenser 2, a filter 3, a capillary tube 4 and an evaporator 5 to form a refrigerant circulation system, and on the pipeline from the condenser 2 to the capillary tube 4, a flow regulating mechanism 6 is set. The mechanism 6 is started and closed synchronously with the start and stop of the compressor 1, and is used to prevent the refrigerant in the high-pressure side condenser 2 from flowing to the low-pressure side where the evaporator 5 is located when the compressor 1 is stopped. The flow regulating mechanism 6 may be a solenoid valve or the like.

[0012] In the case of maintaining the pressure on the condenser 2, in order to ensure that the compressor 1 can be started normally, a pressure relief branch can be set for the compressor 1 so as to balance the pressure at the discharge port and the suction port of the compressor. The specific way is as figure 2 As shown, the pressure relief capillar...

Abstract

The present invention relates to a condenser pressure-retaining energy-saving refrigerator refrigeration system. It uses compressor, condenser, filter, capillar and evaporator to form refrigerant circulation system. A flow regulating mechanism is set on the pipeline leading to the capillary from condenser, said flow regulating mechanism is started or stopped synchronously with starting or stopping of the comprssor. The flow regulating mechanism can make the high-prssure refrigerant being in the condenser do not be fed into evaporator by means of capillary after the compressor is stopped or only small portion of refrigerant can be continuously flowed into evaporator so as to retain the potential energy possessed by high-pressure refrigerant in condenser.

Description

Technical field: [0001] The invention relates to a refrigerator refrigeration system. More specifically, it is a refrigeration system for a refrigerator in which a refrigerant circulation system is formed by a compressor, a condenser, a filter, a capillary tube and an evaporator. Background technique: [0002] At present, the commonly used refrigerators are composed of compressors, condensers, filters, capillary tubes and evaporators to form a refrigerant circulation system. Pressing to the condenser, the pressure of the condenser increases and the pressure of the evaporator decreases. The refrigerant dissipates heat in the condenser and changes from a gas phase to a liquid phase. The gas is sucked into the compressor, and this cycle realizes refrigeration; when the temperature in the box is lower than the set value, the compressor stops working. However, in the actual working process, whenever the compressor stops, the high-pressure refrigerant in the condenser continues ...
