Preset temperature threshold then opens the heat exchanging pipe of the air conditioner so that the liquid refrigerants of low-temp low-pressure is by the heat exchanging pipe
The step of absorbing vaporization after the temperature of the compressor include:
If the indoor environment temperature is less than preset indoor temperature threshold value, the first control valve of the air conditioner is opened, is closed
Second control valve of the air conditioner, so that the liquid refrigerants of low-temp low-pressure absorbs the air conditioner by the heat exchanging pipe
It is vaporized after the temperature of compressor.
9. the control method of air conditioner as claimed in claim 4, which is characterized in that described to judge whether the environment temperature is small
After in the corresponding preset temperature threshold the step of, further includes:
If the environment temperature is greater than or equal to the preset temperature threshold, closes the first control valve of the air conditioner and open
Open the second control valve of the air conditioner.
10. a kind of storage medium, which is characterized in that the storage medium is stored with the control program of air conditioner, the air conditioner
