Air source heat pump heating system

Abstract

The invention belongs to the technical field of energy and power engineering, and relates to an air source heat pump heating system. A four-way reversing valve is connected with an outlet of an oil-gas separator, a working medium inlet of a water cooling condenser, an inlet of a gas-liquid separator and an outlet of an air cooling evaporator; a working medium outlet of the water cooling condenseris connected with an inlet of a separation liquid storer through a balance pipe; a liquid-phase outlet of the separation liquid storer is connected with a first inlet of an evaporation condenser through a first throttling module; a gas phase outlet of the separation liquid storer is connected with a second inlet of the evaporation condenser; a first outlet of the evaporation condenser is connectedwith an inlet of a compressor; a second outlet of the evaporation condenser is connected with an inlet of the air cooling evaporator through a second throttling module; a hot water outlet of the water cooling condenser is connected with a water tank; the water tank is connected with a water pump; the water pump is connected with an auxiliary power supply; and the system adopts a mixed working medium consisting of R124 and R32. The system is high in energy-efficiency ratio, energy-saved, environment-friendly and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of energy and power engineering, and in particular relates to a heat pump heating system, in particular to an air source heat pump heating system. Background technique [0002] 1. Current status of heating in residential quarters [0003] The existing winter heating of residential quarters is generally divided into: centralized heating of urban heating network, independent heating of residential quarters and independent heating of owners. According to the type of energy used, it is further divided into: coal-fired heating, gas heating, electric heating and Water source heat pump heating, etc. The use of air source heat pumps for heating has only just begun in recent years. In recent years, due to environmental protection considerations, some areas have gradually restricted heating methods such as coal and gas, and switched to cleaner electric heating and heat pump heating. [0004] 2. Disadvantages of cur...

Problems solved by technology

Although this patent can solve the problem of the mismatch between the amount of hot water required by users and the heating capacity of the unit in time, because it uses two compressors, there is still a problem that the input electric power needs to be greatly increased when the heating capacity decreases significantly as the ambient temperature drops. The problem is that the COP value of the thermal economy index is still not ideal
