Problems solved by technology

At present, there are a large number of large, medium and small capacity heat pump / air conditioning and refrigeration equipment in China, such as household air conditioners, large, medium and small capacity refrigeration devices, and air-cooled and water-cooled heat pump devices. , an evaporator, and a liquid receiver. Inside the four-way valve, there is a pneumatic control tube used to control the reversing of the four-way valve spool. The inlet of the pneumatic control tube is connected to the inlet of the four-way valve and then connected to the outlet of the compressor. Most of the condensers of air-conditioning devices are cooled by air, and the cooling method is single, and when cooling in this way, a large amount of heat is directly discharged into the atmosphere, which not only pollutes the environment (heat pollution), but also wastes energy, and cannot be released into the air. Condensation heat recovery in

Similar products at home and abroad have disadvantages such as complex refrigeration process transformation, frequent replacement of original components, which is not conducive to production and processing

At the same time, due to the addition of a new heat exchanger, the phenomenon of early evaporation occurs in the process of condensation heat recovery, which affects the cooling effect on the evaporation side and reduces the working capacity of the evaporator.
