(1) Reason analysis
1. Place the high and low temperature test chambers 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 above factors all cause the heat dissipation performance of the condenser to be lowered, so that 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. The following is provided by Shanghai Jianhu Instrument Equipment Co., Ltd. to provide you with solutions.
1. The placement of high and low temperature test chambers should be about 60cm away 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 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, to prevent the condensation tube or The welding plate (wire) is bent. Do not use sharps to remove dirt when spot welding or stamping.
