In summer, air conditioning is frequently used, which inevitably leads to some small problems. I don't know what the meaning of some problems is. Today, I'd like to talk about the defrosting problem of Gree air conditioning. Let's have a look together with interested friends.
What does Gree air conditioning defrost mean
The defrosting of air conditioner can only operate when heating. When the air conditioner is heating, the air conditioner absorbs heat from the outside, which causes the surface temperature of the outdoor unit to decrease. When the outdoor temperature is also very low, the temperature of the external unit can be lower than a few degrees. At this time, the surface of the air conditioner will be covered with a thick layer of frost, which will affect the heat absorption of the air conditioner and reduce the heating effect of the air conditioner, so the air conditioner will every 4 0 minutes to 1 hour will automatically defrost and melt the frost of the external machine.
Gree air conditioning defrosting air conditioning stopped
When the air conditioner defrosts, the internal and external units will not work, only the compressor is working. When the air conditioner is heating, freon absorbs heat on the evaporator of the external unit and turns into high-temperature and high-pressure gas to enter the internal unit for heat release. When the air conditioner needs defrosting, the system immediately stops the operation of the internal and external units. At this time, there will be stored high-temperature and high-pressure gas between the internal and external units. When defrosting, these gas will be collected and then stored in the reverse direction to the external unit, and other high-temperature and high-pressure gases will be discharged into the external unit Liquid, while melting the air conditioning outside the frost. Therefore, when defrosting, the internal machine will not produce hot air. It needs to wait until the external machine of the air conditioner works and the incoming air reaches a certain temperature to produce air.
What does Gree air conditioning defrost mean? Many people don't quite understand why air conditioning defrosts sometimes. What's the use of defrosting? Let's understand the meaning of defrosting.
How is frequent defrosting of Gree air conditioner
When the air conditioner is heating in winter, defrost once every 40 minutes to 1 hour, which is a normal phenomenon. If the defrosting frequency of Gree air conditioner is more than this, it should be caused by the performance degradation or failure of the defrosting temperature sensing probe on the heat exchanger of outdoor unit. It is recommended to replace the defrosting temperature sensing probe.
What are the common troubles of defrosting in air conditioning
1. The lack of refrigerant in the air conditioner will reduce the defrosting capacity of the air conditioner or the defrosting time of the air conditioner will be long.
2. The failure of defrosting sensor of air conditioner results in no defrosting of air conditioner, and the heating effect is greatly reduced.
3. The control panel has failed, causing the air conditioner not to defrost.
