Efficient and novel low-cost air source heat pump combined cooling, heating and power system

Abstract

The invention relates to the air source heat pump combined cooling, heating and power system technology. Compared with the existing combined cooling, heating and power technology, an air source heat pump combined cooling, heating and power system is simpler in structure, low in cost and higher in efficiency. According to the scheme, a common air conditioning system operation system is reserved, only one four-way reversing valve is adopted, but the defects of the single four-way reversing valve technology of an initial combined cooling, heating and power technology are overcome. According to the specific technical scheme of the system, after the output end of a compressor system 1 is connected with a port a of the four-way reversing valve F0, a port e is used for being connected with one end of the working medium side of a total-heat recoverer 4 and an electromagnetic valve F1 through a tee joint, the other end of the working medium side of the total-heat recoverer is connected with an electromagnetic valve F2, and after convergence through a tee joint, the electromagnetic valve F2 and the electromagnetic valve F1 are connected with an expansion valve P1 and an electromagnetic valve F3 correspondingly through a tee joint and then connected with an air conditioning side heat exchanger 3 after convergence through a tee joint; and after being connected with an expansion valve P2 and an electromagnetic valve F4 through a tee joint, the other end of the air conditioning side heat exchanger is connected with a heat source side heat exchanger 2 through tee joint convergence, and after being connected with a port c of the four-way reversing valve, the other end of the heat source side heat exchanger is connected with the input end of the compressor system through a port s.

Description

technical field [0001] The invention relates to the technical field of an air source heat pump triple supply system. Background technique [0002] In order to overcome the shortcomings of the existing air source heat pump air conditioner units that cannot recover heat and cannot provide domestic hot water in transitional seasons, an air source heat pump triple supply air conditioner unit has emerged as the times require. Provide domestic hot water. After several years of development, this type of air-source heat pump triple supply and air-conditioning unit has basically solved the problem that the original basic scheme was difficult to operate in practice by increasing the complexity of the system. From the current point of view, the units that can be used in actual production and life generally use two four-way reversing valves and Other technical solutions for multiple auxiliary valves. Contents of the invention [0003] The purpose of the present invention is to prov...
