Technical Field

The utility model relates to the technical field of refrigeration, specifically a high-efficient heat transfer type fluorine refrigerating system based on force supplies liquid.

Background

Refrigeration is achieved by circulating a refrigerant in a closed system, changing state continuously, and obtaining low temperature. Taking a refrigerator as an example, a compressor sucks low-temperature low-pressure freon gas from an evaporator, compresses the low-temperature low-pressure freon gas into high-temperature high-pressure freon gas, then flows through a thermostatic expansion valve (capillary tube), is throttled into low-temperature low-pressure freon gas-liquid two-phase objects, then the low-temperature low-pressure freon liquid absorbs heat from indoor air in the evaporator to become the low-temperature low-pressure freon gas, and the low-temperature low-pressure freon gas is sucked by the compressor. After the indoor air passes through the evaporator, heat is released, and the temperature of the air is reduced. The refrigerant continuously takes away the heat of the indoor air through repeated cycles of compression, condensation, throttling and evaporation, thereby reducing the temperature of the room.

The structure in the prior art mainly adopts a high-pressure direct liquid supply mode, and has lower energy consumption.
