Air-source heat pumps, also known as "air-source heat pump water heaters," operate on a principle very similar to air conditioners. They use a small amount of electricity to power the compressor, which then compresses the liquid working substance. After passing through an expansion valve, the substance evaporates into a gas state in the evaporator, absorbing a large amount of heat from the air. The gaseous substance is compressed by the compressor into a high-temperature, high-pressure liquid, which then enters the condenser to release heat and heat the water.... This continuous循环加热 process can raise the water temperature to 50°C~65°C.
