Causes and elimination methods of the condenser temperature of the high and low temperature test chamber being too high

1) Reason analysis 1.
The location of the high and low temperature test box is too close to the wall
.

2.
The air temperature in the room is too high
.

3.
The air flow in the room is not smooth
.

4.
There is too much dust and oil on the condenser
.

5.
There is an oil block or dirty block in the condenser
.

6.
Partial blockage in filter drier or capillary
.

The existence of the above points reduces the heat dissipation performance of the condenser, so that the surface heat of the condenser cannot be discharged in time, resulting in an increase in the condensation temperature of the refrigerant and the heat on the tube wall
.

(2) Elimination method 1.
The location of the high and low temperature test box 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 box should not be placed in the corner
.

4.
The dust on the condenser can be removed with a feather duster; for the accumulated oil and dirt, a soft rag can be used to wipe it carefully.
