[0002] At present, in the use of heat pump air conditioners, a heat pump water heater is set to replace the low-energy heating of hot water using electricity and gas, but the heat pump cannot be used as an air conditioner. At present, an evaporating coil and a heat dissipation element are installed in the water tank to replace the fan and the finned heat exchanger in the air-cooled condenser, so as to solve the problem that the heat pump air conditioning system can produce hot water and be used as an air conditioner. At present, a low-boiling-point medium is poured into the heat dissipation element, and the end inserted into the water tank is the hot end, and the end passing through the brick wall is the cold end. When the hot end of the heat dissipation element is heated by hot water exceeding the upper limit of the condensation temperature, the low-boiling-point medium inside boils and evaporates, and the evaporated gas enters the cold end of the heat dissipation element installed with a certain upward inclination angle and condenses. The condensed liquid returns to the hot end of the heat dissipation element by its own weight. The heat dissipation element operates over and over again, transferring the excess heat on the condenser side to the environment to meet the normal operation of the air conditioner.
