Triple-generation system based on energy-saving solar air source heat pump

Abstract

The invention relates to a triple-generation system based on an energy-saving solar air source heat pump. The triple-generation system comprises an air compression unit, a solar heating unit and a refrigerant circulating unit, wherein the air compression unit comprises a first compressor and a gas-liquid separator; the solar heating unit comprises a hot water heat exchanger, a first hot water tank, a solar heat collector, a solar pump and a hot water pump; and the refrigerant circulating unit communicates with a heat exchanger of an air conditioner, a circulating pipeline and an air-cooled heat exchanger. The triple-generation system disclosed by the invention has functions of conditioning air and supplying domestic hot water; meanwhile, solar energy is utilized to the maximum extent to supplement heat required by the system; the utilization rates of solar energy and electric energy are high; renewable energy sources are fully utilized, and energy conservation and environmental protection are realized; the triple-generation system has the advantages of simple structure, reliable operation, greenness and low carbon; the triple-generation system can be used for continuously providing the domestic hot water, refrigerating in summer and warming in winter; more electric energy is saved; and by reasonable control, multiple modes of separately refrigerating, separately supplying heat, separately producing hot water, simultaneously refrigerating and producing hot water, simultaneously heating and producing hot water and the like can be realized.

Description

technical field [0001] The invention relates to the technical field of air source heat pump systems, in particular to an energy-saving solar air source heat pump triple supply system. Background technique [0002] Air source heat pump air conditioners and air source heat pump water heaters are the most common air source heat pump devices in our daily life. Both air source heat pump air conditioners and air source heat pump water heaters have the advantages of energy saving and environmental protection, but there are also many problems: air conditioners (refrigeration, heating ) and hot water are two systems respectively, and the annual equipment utilization rate is low; when the air conditioner is in cooling operation in summer, a large amount of condensation heat is discharged into the atmosphere and is wasted, and this part of the available energy is lost while generating the heat island effect . In addition, the low utilization rate of the refrigerant is also an urgent p...
