Abstract

The invention provides an uninterrupted heating-defrosting heat-pump type air conditioner, which comprises a compressor, a four-way valve, an outdoor heat exchanger, an indoor heat exchanger, an electric refrigerant heater and a gas-liquid separator, wherein the four-way valve is communicated with one end of the outdoor heat exchanger; an outdoor electronic expansion valve is arranged between theother end of the outdoor heat exchanger and one end of the indoor heat exchanger; a first check valve, a capillary tube and a first electromagnetic valve, which are in sequential serial connection, form a first circuit branch; one end of the first circuit branch is communicated with a pipeline between the other end of the outdoor heat exchanger and the outdoor electronic expansion valve; the other end of the first circuit branch is communicated with the pipeline between the other end of the indoor heat exchanger and a fourth interface of the four-way valve; a second electromagnetic valve and a second check valve in serial connection form a second circuit branch; one end of the second circuit branch is communicated with the pipeline between the outdoor electronic expansion valve and one end of the indoor heat exchanger; and the other end of the second circuit branch is communicated with the pipeline between a third interface of the four-way valve and one end of the gas-liquid separator. The air conditioner has the characteristics of stable indoor heating effects and thorough defrosting.

Description

technical field [0001] The invention relates to a heat pump air conditioner, in particular to a heat pump air conditioner with continuous heating and defrosting. Background technique [0002] When the air conditioner performs low-temperature heating in winter, because its evaporation temperature is lower than zero, the surface of the heat exchanger of the outdoor unit will be frosted or frozen, which will affect the heating effect of the air conditioner. At present, it is generally adopted to switch to cooling operation to melt the frost layer or ice layer on the outdoor heat exchanger. However, this method will cause the indoor unit to be unable to provide heat during defrosting operation, which will inevitably affect the corresponding indoor temperature and cannot meet the requirements. The user's heating requirements in winter, and frequent start-up and shutdown and positive and negative flow of refrigerant will also have a greater impact on the system. In response to th...
