Solar energy and air-source heat pump heating and water heating complementary system and method

Abstract

The invention discloses a solar energy and air-source heat pump heating and water heating complementary system and method. The system comprises an air-source heat pump, wherein an indoor unit of the air-source heat pump and an insulation water tank form a closed water path, the indoor unit of the air-source heat pump and a floor heating system form a closed water path, and a solar heat collector is used for supplying heat to the insulation water tank through a heat exchange pipeline II and supplying heat to a heat exchanger and a water receiving tray of an outdoor unit of the air-source heat pump through a heat exchange pipeline I, so as to defrost; a central controller is used for controlling the opening / closing of various electromagnetic valves and setting various temperatures. According to the solar energy and air-source heat pump heating and water heating complementary system and method, disclosed by the invention, the problem that the volume of hot water for living supplied by solar energy in winter and rainy days is insufficient can be solved by an air-source heat pump system, and the heat supply amount and heat efficiency are greatly increased; in addition, heat supplied by the solar energy is used for removing the icing of the heat exchanger and the water receiving tray of the outdoor unit of the air-source heat pump, so that the stable operation of the air-source heat pump is guaranteed.

Description

technical field [0001] The invention relates to a heating and hot water supply system and method, in particular to a solar energy and air source heat pump heating and hot water complementary system and method. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the human demand for energy continues to expand, and the use of renewable energy and clean energy is increasingly widely used in various fields. Solar collectors rely on heat collecting tubes to absorb solar radiation to heat water, and then transport hot water to water tanks for storage through pipelines, and then transport them to users. The air source heat pump uses electric energy to drive the heat pump system to absorb heat from the air and release the heat to heat water. The air source heat pump has the characteristics of high efficiency, energy saving, green environmental protection, etc., but when the outdoor temperature is too low in winte...
