Description

technical field

[0001] The invention relates to a vapor compression refrigeration / heat pump air conditioner unit, in particular to a high-efficiency air conditioner unit with multiple refrigerant circuits. Background technique

[0002] With the continuous improvement of living standards, the power consumption of air conditioners continues to rise rapidly, and currently accounts for more than 40% of building energy consumption. Air conditioning units based on the vapor compression cycle are the most widely used at present.

[0003] The main structure of the vapor compression air conditioning unit includes a compressor, a condenser, an evaporator, and a throttling device. Its working process is: the low-temperature and low-pressure liquid refrigerant first absorbs heat from the low-temperature heat source in the evaporator and is vaporized into low-pressure steam. Then the refrigerant gas is completely compressed into high temperature and high pressure vapor in the compresso...
