Abstract
The invention relates to an energy-saving control method formed by combining a heat pump and a solar water heater. The method is characterized by comprising the steps that water using peak time t1, a water temperature upper limit temperature T3 and a water temperature lower limit temperature T4 are input and set by a user via an input module; the temperature of an outdoor environment temperature sensor T1 and the temperature of a water tank temperature sensor T2 are collected through a temperature collector; a microprocessor calculates total heat needed for heating and the like according to the water using upper limit temperature T3 and the current water tank temperature T2; when time reaches the optimum staring time t2 of a heat pump system, the microprocessor outputs an operating signal of the heat pump system, and the heat pump system begins to operate; when the water tank temperature T2 reaches a water tank middle temperature T5, the heat pump system stops operating; after the heat pump system stops operating, due to sudden changes of weather or due to the fact that the water tank temperature T2 is reduced to the temperature lower limit temperature T4 set for the water tank caused by a small amount of water before the water suing peak time t1 is set, the heat pump system is automatically started a period of time earlier before the water using peak time t1 until the heat pump system reaches the temperature upper limit temperature T3 set for the water tank. The heat pump system can operate during a period time with the highest energy efficiency all day long, so energy-saving effects are better.
