The invention discloses a water source heat pump water heater collecting heat from solar energy and air energy. The water source heat pump water heater is composed of a water source heat pump unit, a heat collecting circulation pump, an air energy heat exchanger, a solar heat collecting panel, a heating circulation pump, a hot water tank and a bypass valve. An evaporator outlet of the water source heat pump unit is connected to the air energy heat exchanger through the heat collecting circulation pump, is connected to the solar heat collecting panel, and returns back to an evaporator inlet of the water source heat pump unit. The warm water with the heat collected from the solar energy and the air energy serve as a water source and is conveyed to an evaporator, and after being increased, the heat of the water source heat pump unit is conveyed to the hot water tank to prepare hot water through a condenser of the water source heat pump unit. The working time frame of the water source heat pump unit is the same as the solar energy heat absorbing time frame, the circulating water with the heat collected from the solar energy and the air energy serves as the water source, the absorption of the solar energy heat is not affected, the heat collecting efficiency of the solar energy absorption and the air energy absorption can be improved, and the total energy efficiency ratio is improved.
Description
technical field [0001] The invention relates to a solar water heater, in particular to a water source heat pump water heater with solar energy plus air energy heat collection. Background technique [0002] Conventional flat-panel solar water heaters, the solar collector plate is directly connected to the hot water tank through the circulation pump, and the water temperature in the hot water tank is gradually raised to the temperature for bathing through circulation heating. In order to ensure hot water supply when solar energy is insufficient, the water tank is also equipped with an auxiliary heat source. The most commonly used auxiliary heat source is the air energy heat pump unit, because it is more energy-saving. The auxiliary heat source is usually set to work when there is no sun in the afternoon, so as not to affect the absorption of solar energy. If the solar radiation is small, the water temperature in the hot water tank is low, and the water in the water tank cann...
