Part is realized, can also be realized by modes such as voice and gestures, not limited herein.Preset rotation speed can be air conditioner lowest gear
Rotating speed be alternatively the rotating speed that user pre-sets, or the preset rotation speed is the carry out refrigerant recovering that developer is specially set
Rotating speed, the rotating speed is relatively low rotating speed.
Step S20, when blower fan runs preset duration with preset rotation speed indoors, obtain the temperature that temperature sensor detects
As initial indoor heat exchanger temperature and/or initial outdoor sensor temperature, and close throttling control assembly；
Step S30, the temperature that timing acquisition temperature sensor detects, and calculate the temperature rising value of indoor heat exchanger

Step S40, when heat exchange temperature rising value is more than the first preset temperature value indoors, and/or in outdoor heat exchanger
When temperature drop-out value is more than the second preset temperature value, the first magnetic valve is closed.
Because during refrigerant recovering, refrigerant recovering is into compressor in indoor set pipeline, then in indoor heat exchanger
Refrigerant is recycled in compressor so that the temperature of indoor heat exchanger constantly raises, you can by the temperature of indoor heat exchanger
Appreciate to determine whether to complete refrigerant recovering；And the refrigerant in outdoor unit pipeline is flowed into outdoor heat exchanger, simultaneously because outdoor
The refrigerant of heat exchanger no longer exchanges heat, then outdoor heat exchange refrigerant therein can constantly reduce temperature, the i.e. temperature in outdoor heat exchanger

It is worth and/or whether is less than the 4th preset temperature value in the difference of outdoor heat exchanger temperature and outdoor temperature；
The difference of heat exchange temperature and indoor temperature is less than the 3rd preset temperature value and/or in outdoor heat exchanger temperature indoors
When degree and the difference of outdoor temperature are less than four preset temperature values, step S40 is performed, that is, closes the first magnetic valve.
Because indoor heat exchanger and outdoor heat exchanger will not be exchanged heat again during refrigerant recovering, then interior is changed
The temperature of hot device and outdoor heat exchanger can be close to indoor temperature, then the difference of heat exchange temperature and indoor temperature is small indoors
In the 3rd preset temperature value and/or when the difference of outdoor heat exchanger temperature and outdoor temperature is less than four preset temperature values, sentence
Determine air-conditioner coolant recovery to complete.
Further, when heat exchange temperature rising value is more than the first preset temperature value indoors, and/or in outdoor heat exchanger

The difference of heat exchange temperature and indoor temperature is less than the 3rd preset temperature value and/or in outdoor heat exchanger temperature and outdoor temperature
When difference is less than four preset temperature values, judge that air-conditioner coolant recovery is completed, the accurate of judgement is completed to improve refrigerant recovering
Rate.
It is understood that to reduce the detection number of indoor heat exchanger temperature and/or outdoor heat exchanger temperature to reduce
System energy consumption, the temperature that temperature sensor detects can be obtained, and calculate indoor heat exchanger after air conditioner runs preset duration
Temperature rising value and/or outdoor heat exchanger at a temperature of depreciation, to carry out the judgement of refrigerant recovering completion.
The temperature of depreciation and/or outdoor heat exchanger at a temperature of technical scheme is by indoor heat exchanger disclosed in the present embodiment
Rising value determines whether refrigerant is completed so that air conditioner can complete refrigerant recovering in time, avoid the waste of the energy.
