Air energy machine 2 is a prior art, which includes an evaporator, a compressor, a condenser and an expansion valve, etc. The evaporator is responsible for absorbing heat energy from the surrounding air. The compressor compresses low-temperature and low-pressure gas into high-temperature and high-pressure gas. The condenser releases heat to heat the water in the water storage tank 3. The expansion valve adjusts the flow and pressure of the refrigerant.
