Heat pump system

Abstract

The invention provides a heat pump system which comprises a solar power hot water subsystem, an air-conditioner heat-exchange working medium circulation subsystem and an absorption type circulation subsystem. The absorption type circulation subsystem comprises a solution generator, a first condenser, a first throttle valve, a first evaporator and an absorber; the solution generator and the absorber are connected through two pipelines and form a refrigeration working medium circulation circuit; and the solution generator, the first condenser, the first throttle valve, the first evaporator and the absorber are sequentially connected. The air-conditioner heat-exchange working medium circulation subsystem comprises a four-way valve, a compressor and a subcooler, an outlet pipeline of the compressor is connected with a first valve port of the four-way valve, a pipeline of the solar power hot water subsystem and the outlet pipeline of the compressor both penetrate through the solution generator, and the subcooler is coupled to the first evaporator. According to the heat pump system, the solar power, wind energy and electric energy are utilized efficiently fully and complementally to drive an air conditioner to conduct refrigerating and heating, and electricity network pressure in the peak time of electricity using is effectively alleviated.

Description

technical field [0001] The invention relates to a heat pump system, in particular to a heat pump system that can utilize renewable energy. Background technique [0002] At present, the world's energy structure is dominated by fossil energy such as oil, natural gas, and coal, accounting for 85% of the total energy consumption. The fossil energy will eventually be exhausted, and it will also bring serious environmental problems. At present, the energy consumption of my country's construction industry accounts for about 30% of the total energy consumption in the country. With the acceleration of urbanization and the improvement of people's living quality, the proportion of energy consumption in buildings will eventually rise to about 35%. Weaknesses of development. Among them, the power consumption of air conditioners accounts for more than half of the energy consumption of buildings, and the time of power consumption of air conditioners is concentrated, which directly leads to...
