Problems solved by technology
[0005] The purpose of the present invention is: in order to solve the problem that the calling method of heat-melting through the reversing valve is easy to affect the indoor heating intensity, since the thickness of the outdoor frost is gradually increasing, after the frost layer is gradually thickened, it takes a lot of time to dissolve the frost. A long time will affect the heat supply efficiency, and the energy storage heat exchanger has a small space density, which cannot meet the needs of air flow and heat dissipation after frosting. An air source heat pump defrosting method and an air source heat pump are proposed. Hot and cold water unit

The invention discloses an air-source heat pump defrosting method and air-source heat pump water chiller-heater unit, relates to the technical field of air-source heat pumps, and belongs to an energy-saving heat exchange device. The water chiller-heater unit comprises an air compressor, and one side of the air compressor communicates with an internal heater unit; the other side of the air compressor is sequentially connected with a plurality of heat exchange mechanisms through pipelines; and heating mechanisms are arranged on one sides of the heat exchange mechanisms, and a driving mechanism is arranged on the top of the heating mechanisms. According to the water chiller-heater unit, after heating boxes are moved, the heating boxes are fit with a frosted heat exchange plate on one side through heat-conducting fins expanded thermally, and therefore fit heat exchange between the heating boxes and the heat exchange plate on one side can be achieved through the heat-conducting fins deformed by absorbing heat; heat exchange gaps between the heat exchange plates are prevented from being affected after the cooled heating boxes are reset; by the aid of the movable heating boxes, the heat exchange and ventilation capacity of the heat exchange plates is prevented from being affected while the fit defrosting capacity is improved, and meanwhile through synchronous heating of packages of the heating boxes arranged at intervals, defrosting is improved; and the heat supply influence on the internal heater unit is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of air energy heat pumps, belongs to an energy-saving heat exchange device, and in particular relates to an air source heat pump defrosting method and an air energy heat pump cold and hot water unit. Background technique [0002] Air energy heat pump is a hot water unit that realizes heat exchange by absorbing the temperature in the air. It uses the heat in the air to generate heat energy. It is an energy-saving heat exchange device. In order to ensure the heat dissipation of the air energy heat pump in the studio, it is necessary to set up a heat exchange unit outdoors to achieve heat exchange with the air, but in cold weather, after the external heat exchange unit and the outdoor heat exchanger are frosted, the frost The continuous thickening of the layer leads to the increase of thermal resistance and the increase of air flow resistance, which reduces the heating capacity and the COP of the unit, resultin...
