Features of CO2 air source heat pumpsCarbon dioxide heat pump is a
kind of refrigeration device with carbon dioxide (R744) as
refrigerant. It captures low grade heat source from natural air,
water and other media through refrigeration cycle, and transfers it
to high quality heat energy which can be produced and used by
people. Different from conventional heat pump, carbon dioxide heat
pump can produce 65-90°C high temperature hot water, which has
unparalleled advantages such as energy saving and environmental
protectionThe compressor inhales low temperature and low pressure
gas carbon dioxide refrigerant from the evaporator, compresses the
carbon dioxide refrigerant into high temperature and high pressure
supercritical fluid by doing work, and the high temperature and
high pressure supercritical fluid enters the gas cooler to exchange
heat with water. After the high pressure fluid is reduced by the
throttle of the expansion valve, the heat in the surrounding air is
absorbed by the fan in the evaporator and evaporated into a low
pressure gas, which is compressed by the suction compressor, so
that the hot water is produced by repeated circulation. Some
