1. Directly feel that the cooling effect of the air conditioner is not good, and the temperature of the air outlet cannot go down - this is generally a slight poor heat dissipation. 2. The pressure of the air conditioning system, especially the high-pressure part, may cause the air conditioning pipeline to burst. 3. As a result, the compressor load increases, the internal pressure of the compressor rises, and the piston cylinder body is difficult to compress. If it is more serious, the cylinder body load will be too heavy, causing the air conditioning belt to slip. 4. Poor extreme heat dissipation - this was tried when doing experiments in Xinjiang. Pressure rises too fast, piston cylinder
