Abstract

The invention discloses a solar energy and air source heat pump dual energy complementary domestic hot water supply system. According to the solar energy and air source heat pump dual energy complementary domestic hot water supply system, all-glass evacuated solar collector tubes, a thermal collection header and a collector support form a solar thermal collector unit, and a solar thermal collectorand a solar thermal collection water tank are connected through a pipeline to form a solar water heating system. Under the sunshine condition, the solar energy serves as a hot source to heat water inthe water tank, and when the solar irradiation amount cannot meet the requirement or in continuous overcast and rainy weather, an air source heat pump is started to carry out heating. The air sourceheat pump is connected with the constant-temperature water tank, an automatic temperature control state is set, and the air source heat pump is automatically started or stopped according to the temperature of the constant-temperature water supply water tank. By means of the solar energy and air source heat pump dual energy complementary domestic hot water supply system, energy is saved, and safetyand reliability are achieved.

Description

technical field [0001] The invention relates to the field of high-efficiency utilization of renewable energy, in particular to a supply system for domestic hot water combined with solar energy and an air source heat pump. Background technique [0002] At present, all universities and enterprises provide domestic hot water for students and employees, and most of them use solar collectors and electric boilers as heat sources. The water storage tank is cyclically heated by the solar collector installed on the roof. When the solar irradiance is not enough or the weather is cloudy and rainy, it is necessary to start the auxiliary heat source of the electric boiler installed in the equipment room for heating to ensure that there is enough hot water to meet the requirements. need. Electric boilers are also called electric heating boilers and electric heating boilers. As the name suggests, it uses electricity as energy and converts it into heat energy, and outputs steam, high-tempe...
