The reason for the abnormal overheating of the condenser tube of the high and low temperature damp heat test chamber is that when the high and low temperature damp heat test chamber is used, the condenser tube of the high and low temperature damp heat test chamber is often abnormally overheated but the cause is not known.

(1) Reason analysis
1. The placement of the high and low temperature damp heat test chamber is too close to the wall.
2. The air temperature in the room is too high.
3. The air in the room is not flowing smoothly.
4. There is too much dust and oil on the condenser.
5. There is oil blockage or dirty blockage in the condenser.
6. There is partial blockage in the drying filter or capillary. The presence of the above factors reduces the heat dissipation performance of the condenser.
The surface heat of the condenser cannot be discharged to the outside in time, causing the condensation temperature of the refrigerant and the heat on the pipe wall to rise.
(two) exclusion method
1. The placement position of the high and low temperature damp heat test chamber should be about 1500px from the wall;
2. The air temperature in the room should be maintained at 15 ~ 25 °C.
3. The air in the room should be circulated. For this reason, the high and low temperature damp heat test chamber should not be placed in the corner of the wall.
4, the dust on the condenser, can be removed with feather duster; for the accumulation of more oil dirt, you can use a soft rag, carefully wiped with carbon tetrachloride, do not use too much force when wiping,
In case the condensation tube or the welding plate (wire) is bent. Do not use sharps to remove dirt when spot welding or stamping.
