Abstract：
Theoretically analyses variety patterns of the main performance parameters with the seasonal fluctuation, and discusses the influencing factors and their effects during actual operation. States that the patent of the multifunction unit modified from the existing air conditioner makes it more energy efficient than the conventional heat pump water heater and is simpler in structure and more reliable in operation.
