Abstract

The embodiment of the invention discloses a split type heat pump air conditioner which comprises a controller and an outdoor unit which is provided with a compressor and an outdoor heat exchanger. The outdoor heat exchanger is provided with a gas flow hole; the gas flow hole is communicated with an exhaust hole or a gas inlet of the compressor by a four-way valve; a bypass pipeline is also arranged between the exhaust hole of the compressor and the gas flow hole of the outdoor heat exchanger; a solenoid valve is arranged on the bypass pipeline; a gas pressure sensor is arranged on the gas flow hole and is used for sensing the air pressure of the gas flow hole; the controller receives a gas pressure value Ps detected by the gas pressure sensor under a heating mode and regulating the open degree of the solenoid valve according to the gas pressure value Ps detected by the gas pressure sensor so that the gas pressure of the gas flow hole is more than or equal to a set gas pressure value P0, so that the frosting of the outdoor unit can be effectively delayed; therefore, the problem of the solution to the frosting of the outdoor unit during heating of the split-type heat pump air condition can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a split heat pump air conditioner and a method for delaying its frosting. Background technique [0002] When the split heat pump air conditioning system is heating, when the outdoor ambient temperature is lower than freezing point, the water vapor in the air will condense on the surface of the heat exchanger, and as time changes, a frost layer will form on the surface of the heat exchanger. Frosting directly increases the heat transfer resistance between the surface of the heat exchanger and the flowing air, which reduces the air flow through the heat exchanger and reduces the heat exchange efficiency, resulting in a decrease in the heat transfer of the system and the heating condition of the system. deteriorating, and measures are required to defrost. [0003] In the prior art, measures are generally taken to remove the frost after the outdoor unit of the air condition...
