2.OPERATION PRINCIPLES

The compressor absorbs from the evaporator the low-temperature and low-pressure gas refrigerant,
compress the refrigerant into high-temperature and high-pressure gas, and the gas will enter the
condenser to exchange energy with water, during which, the gas is condensed in the condenser into
low-temperature liquid to discharge a lot of heat, which is absorbed by water to increase its temperature.
Then, when the high-pressure and low-temperature liquid throttles and reduces its pressure in expansion
valve, due to the fan in the evaporator, it absorbs energy from the surrounding air to evaporate into
low-pressure gas and then is pumped into the compressor to be compressed, thus entering another cycle
to produce hot water.
