The cooling effect of the Midea KFR-23GWHY air conditioner is poor.
Beijing Midea Air Conditioning Maintenance Telephone provides analytical data.
Analysis and inspection: After the air conditioner has been running for a while, frost forms on the indoor evaporator. The low-pressure pressure was measured at 0.35 MPa, which is lower than normal. After adding refrigerant, the pressure remained unchanged. After the air conditioner continued to run for some time, frost appeared on the return pipe of the outdoor unit, leading to suspicion of an ice blockage. During the refrigerant recovery process, when the wrench was used to unscrew the cap of the three-way shutoff valve, it was found that the three-way shutoff valve was not fully opened, causing the circuit to be obstructed. This resulted in frosting. After fully opening the three-way shutoff valve and adjusting the pressure to the normal value, the air conditioner operated normally.
