Common faults and treatment methods of Gree air conditioning

Gree air conditioner has been used for a long time, and the failure to clean the filter screen in time leads to the blockage of internal air circulation, which will affect the heating effect of the air conditioner to a certain extent. Excessive dirt on evaporator and condenser will also reduce the heat transfer effect, resulting in a decrease in heating capacity and an increase in power consumption; The heating temperature is set too low. Air-conditioned room door, hole is not blocked, or often open the door, resulting in indoor heat loss. , it will inadvertently cause air conditioning heating weakness.

1. Insufficient refrigerant: a simple self-check can be conducted to determine whether there is fluorine leakage.

2. Four-way valve cross air: the heat pump air conditioner switches the cooling and heating states through the four-way valve. Some refrigerants that should participate in heat exchange directly flow back to the air return pipe from the compressor outlet pipe at the four-way valve, which leads to the decrease of refrigerants participating in heat exchange and the decrease of heat exchange efficiency, thus resulting in insufficient heating capacity.

3. Leakage of one-way valve (also known as check valve): the pressure difference between high and low pressure in refrigeration system decreases, the temperature of outdoor heat exchanger increases, and the heat obtained from the outside decreases, resulting in insufficient heating capacity. When testing the system pressure, it will be found that the low pressure side pressure rises and the pressure difference between high and low pressure drops.
