Problems solved by technology

The heat energy of this defrosting method mainly comes from the power consumption of the compressor, so the defrosting speed is relatively slow, but if the defrosting time is too long, the indoor temperature will still drop by about 10°C
In summary, the current defrosting methods all have great drawbacks.

Abstract

The invention discloses an air source heat pump anti-frosting system combined with a photovoltaic system. The air source heat pump anti-frosting system comprises a condenser (1), an evaporator (3), a water pump (6), a water tank (5), an expansion valve (7) and a compressor (8), wherein a heat exchange coiled tube (41) is arranged in a photovoltaic system generation device (4); an outlet end of the heat exchange coiled tube (41) communicates with a connecting pipeline between a condensing channel and the expansion valve (7); an inlet end of the heat exchange coiled tube (41) is connected with one end of a heating pipeline (42) in the evaporator (3); the other end of the heating pipeline (42) is connected with one end of a switch valve (2); and the other end of the switch valve (2) communicates with a connecting pipeline between the condensing channel and the compressor (8). The air source heat pump anti-frosting system combined with photovoltaic system disclosed by the invention can increase the temperature of air around the heat pump evaporator, prevents frosting, and can improve power generation efficiency of the photovoltaic system.

Description

technical field [0001] The invention relates to an air source heat pump anti-frost system combined with photovoltaics, which belongs to the field of heat pump equipment. Background technique [0002] As a heat transfer device, the air source heat pump uses the thermodynamic cycle of the refrigerant to absorb heat from the air and realize the transfer of heat. It is widely used as an energy-saving and environmentally friendly cooling and heating device, especially in the northern " Coal-to-electricity heating has been promoted. However, when the air source heat pump operates in a low-temperature environment in winter, the refrigerant in the evaporator needs to absorb heat from the environment, so the evaporation temperature must be lower than the outdoor ambient temperature. When the surface temperature of the finned tube is lower than the air dew point temperature, the air will The water vapor in the air will condense into ice crystals and accumulate on the surface of the f...
