Background

The heat pump technology is a novel energy-saving refrigeration and heat supply technology and is mainly applied to the field of heating and air conditioning of buildings for a long time. Because of the good performance of heat pump heating in the aspects of energy saving, consumption reduction and environmental protection, the sanitary hot water supply system also increasingly adopts heat pump equipment as a heat source. The air source heat pump taking outdoor air as a heat source has the advantages of simple structure, no need of a special machine room, convenience in installation and use and irreplaceable advantages in the aspect of sanitary hot water supply. However, one of the main disadvantages of the air source heat pump is that the heating capacity and the heating performance coefficient are reduced along with the reduction of the outdoor air temperature, so that the use of the air source heat pump is limited by the ambient temperature, and the air source heat pump is generally applicable to areas with the lowest temperature of more than-10 ℃. The heat pump technology and solar energy are combined to supply domestic hot water, and many researches in the aspect are carried out at home and abroad, wherein one mode is a solar heat pump system which directly uses an air source heat pump as an auxiliary heating device of a solar system, and the other mode is a solar heat pump system which uses solar hot water as a low-temperature heat source or uses a solar heat collector as an evaporator of the heat pump. The former mainly uses solar energy direct heating and uses an air source heat pump as an auxiliary to solve the continuity problem of solar energy heat supply, but still cannot get rid of the influence of the environmental temperature on the heating performance of the heat pump, and the latter completely uses solar energy as a heat pump heat source to greatly improve the utilization efficiency of the solar energy, but when the solar energy resource is insufficient, other auxiliary heat sources still need to be added, and the heat supply capacity of the heat pump is limited by the solar energy collection amount, and the scale is generally smaller.
