Abstract

The invention relates to a solar-energy auxiliary multifunctional heat pump system, which comprises connected air-conditioning module and composite water heater module. Wherein, the air-conditioning module is formed by serially connected compressor, four-way valve, indoor heat exchanger, first throat element, coil tube heat exchanger, second throat element and outdoor heat exchanger; the composite water heater module is between the first and second throat elements, which comprises a closed support thermal-insulated water bank, a solar-energy collector, a coil tube heat exchanger and the second electromagnetic valve. Said composite water heater module has the functions of heat pump water heater storage pot, and the function of auxiliary steamer. The invention can realize multifunction of air conditioner and water heater to supply the hot water in 50-90Deg. C and confirm the stability of system in winter.

Description

technical field [0001] The invention belongs to the fields of air source heat pump air conditioners, heat pump water heaters and solar energy utilization, and in particular relates to a solar energy assisted multifunctional heat pump system. Background technique [0002] The oil crisis and the greenhouse effect have posed serious challenges to the world in energy and environmental issues. Whether it is power shortage or global warming, the root cause lies in the irrational use of energy. People often directly burn high-grade fuels such as oil, natural gas and coal for low-grade heating needs, which not only makes the actual utilization rate of energy low, but also produces a large amount of CO 2 And other greenhouse gases, these are the culprits of the greenhouse effect. Therefore, the key to solving energy and environmental problems lies in the rational use of energy and the improvement of energy utilization. [0003] Through thermodynamic analysis, it can be known that ...
