When defrosting control instruction is received, the 4th control valve 102 is controlled to be all turned on；
The step S40, further includes：
When receive heat control instruction when, control it is described 4th control valve 102 close.
Under defrost pattern, the 4th control standard-sized sheet of valve 102 makes the pipeline of the setting storage heater 70 keep unimpeded,
It is beneficial to refrigerant to transmit to the compressor 10.
During normal heating mode, the 4th control valve 102 is closed, and is conducive to further strengthening setting the storage heater 70
Pipeline to the cut-out effect of refrigerant, prevent refrigerant from flowing through the storage heater 70 and influence produced on the heating effect of heat pump air conditioner.
It should be noted that in the control method of above-mentioned each heat pump air conditioner, describedization can be entered using various methods
White pattern.For example, when the frost thickness on the outdoor heat exchanger 50 is detected more than preset value, can be empty to the heat pump
The control module of tune sends defrosting control instruction, wherein, frost thickness detection can be realized by modes such as ultrasound examinations, when
When detecting frost thickness less than preset value, sent to the control module of the heat pump air conditioner and heat control instruction.
And for example, lasting detection or timing detects the environment temperature of the outdoor heat exchanger 50, when the environment temperature is low
When preset temperature, defrosting control can be sent to the control module of the heat pump air conditioner and instructed, it is low when environment temperature is detected
When preset temperature, sent to the control module of the heat pump air conditioner and heat control instruction.
Optionally, the wall surface temperature of outdoor heat exchanger 50 described in Jiang Ce, when avoiding temperature from being less than preset value, to the heat
The control module of pump air-conditioning send defrosting control instruction, when detect avoid temperature be less than preset value when, to the heat pump air conditioner
Control module send and heat control instruction.
Can also be when the environment temperature of the outdoor heat exchanger 50 be less than preset value, time opening defrost pattern, and
After continuing Preset Time, stop defrost, into heating mode.
Control valve specifically described herein can be motor-driven valve.
