1、Slow speed of the external fan
Repair method: air conditioning fan because of rust or stuck and so on to make the wind speed speed slow. The air conditioning fan bearing foreign matter clean up, at the same time will be in the fan shaft drops on some lubricant, so that the fan to restore speed. Also air in the system can cause.
2、The outside unit is covered by something
Air conditioning outside the machine around the placement of debris or covered by something, so that the air conditioning outside the machine can not be normal heat dissipation.
Repair method: do not place sundries around the air conditioning unit, and do not cover the unit with something.
3、Too much refrigerant
Too much refrigerant will also make the air conditioner internal pressure is too large, resulting in air conditioning high-pressure protection.
Repair method: just drain the excess refrigerant can be solved.
4, the outside environment temperature is too high
When the outside environment reaches a high temperature of 43 degrees, the air conditioning heating will be difficult to dissipate the phenomenon, then the air conditioning will appear high-pressure protection, when the outdoor higher than 43 degrees when the air conditioning is very difficult to work, can only temporarily do not open the air conditioning.
5, control circuit abnormalities
When the control circuit inside the air conditioning failure, the air conditioning internal can not work properly, resulting in internal pressure, this time there will be protection. Check the control circuit where the problem, replace the corresponding parts to solve the problem.
6, other reasons
The external unit is installed in the environment of poor heat dissipation, such as narrow stairwells, behind billboards, inside the grille. In the summer equipment has been running at high temperatures, in fact, the manufacturer's laboratory to do experiments, the maximum outdoor ambient temperature of 50 ℃ within the equipment can operate normally, the equipment once the high temperature continues to run, it can not operate normally, until the real high-pressure protection;
R410A refrigerant high pressure protection value reference: 4.2MP (43kgf/cm²);
The high pressure protection protection value for R22 refrigerant is 2.65MP (26.5kgf/cm²).
Outdoor unit of the return air space, in a narrow air conditioning space inside, only the external fan cooling air area is far from enough, in order to meet the equipment of the return air (air intake) space, how big the condenser, there should be how big the return air area, if the return air part of the grille blocking, please also remove, in order to ensure that the equipment is well ventilated and air exchange.
