Abstract

The invention discloses a double-channel flow regulating cold insulation energy saving system which is characterized by comprising a compressor, a condenser, a refrigerating evaporator, a freezing evaporator, a first throttling element and a second throttling element. An exhaust port of the compressor is connected with the condenser by an upstream pipeline, a three-way regulating valve is arranged on a downstream pipeline of the condenser, an outflow port of the three-way regulating valve is connected with the freezing evaporator by the first throttling element, another outflow port of the three-way regulating valve is connected with the refrigerating evaporator by the second throttling element, the freezing evaporator is connected with the refrigerating evaporator by a pipeline, and the refrigerating evaporator is connected with a gas suction port of the compressor by a return gas pipeline. The double-channel flow regulating cold insulation energy saving system has the advantages that the double-channel flow regulating cold insulation energy saving system is simple in structure and low in increased cost, loss can be reduced when pressure of the refrigerating system is built up, the stop time of the system can be prolonged, and accordingly purposes of cold insulation and energy preservation can be achieved.

Description

technical field [0001] The invention relates to a refrigerating system used in refrigerating equipment such as a refrigerator and a freezer, in particular to a dual-channel flow-regulating cold-preservation and energy-saving system. Background technique [0002] The refrigerating system used in the existing mechanical temperature-controlled refrigerators mostly adopts the structural mode of upper refrigerating and lower freezing. It includes a compressor, a condenser, a refrigeration evaporator, a refrigeration evaporator and a throttling element. The exhaust port of the compressor is connected to the condenser through a pipeline, and the condenser is connected to the refrigeration evaporator through a throttling element. Connect the refrigerated evaporator, and the refrigerated evaporator is connected to the suction port of the compressor through a pipeline. During the operation of the refrigeration system, the throttled refrigerant first enters the refrigeration evaporato...
