Problems solved by technology

[0002] Traditionally, a set of air-conditioning systems, a set of boiler heating systems, and independent water heaters are separately set up in the commercial and civil areas for refrigeration, heating, and hot water to meet user needs. Due to the large initial investment, large equipment footprint, and system maintenance Issues such as complexity, high energy consumption, large resource consumption, and unfavorable environmental protection have fallen behind the needs of the development of the times
[0003] At present, solar energy is mostly used for hot water supply due to its low heat density, and due to the instability of solar energy, it still needs to be supplemented by other energy sources; due to the limitation of working conditions, the heating of refrigeration and air-conditioning systems in winter is insufficient, so it is difficult to solve the problem in the northern region. Heating problem; a set of independent heating system has a lot of idle waste due to its short service life, and the maintenance cost is high
[0004] The combination of solar energy and heat pump refrigeration system is of great significance in the composite energy system. Solar energy is clean energy and can be supplied free of charge for a long time. The heat pump refrigeration system is an energy-efficient utilization system. Unit energy consumption can obtain multiple energy sources. Heat pumps can solve the problem of insufficient solar energy heating. Solar energy can improve the operating efficiency of heat pumps, but both solar energy and heat pumps have the problem of lower operating efficiency as the outdoor temperature drops, that is, the combination of solar energy and heat pumps can meet the cooling, heating and hot water needs of the family in most of the time , but in colder areas in winter, it is still unable to meet the needs of family heating
[0005] Auxiliary composite energy such as solar energy and electric heating or gas can solve the problem of hot water and heating, but it cannot solve the problem of cooling. The energy is used once, and the utilization efficiency is low. The unit energy consumption can only obtain double the energy at most.
