Excessive exhaust temperature of industrial chillers is the key to the impact.

1. Excessive exhaust temperature of industrial chiller compressor will directly reduce the air transmission coefficient and increase the shaft power. In addition, the decrease in lubricating oil viscosity will cause abnormal wear of bearings, cylinders, and piston rings, and even cause accidents such as burning bushes and cylinders.

2. The operator of the industrial chiller should check the overheating of the compressor. If the overheating is severe, it will cause the piston to expand excessively and become stuck in the cylinder, and it will also cause the built-in motor of the hermetic compressor to burn out.

3. Once the exhaust temperature of the industrial chiller compressor is too high, it will directly cause the lubricating oil and refrigerant to thermally decompose under the catalysis of the metal, and generate acids, free carbon, and moisture that are harmful to the compressor. Free carbon accumulates on the exhaust valve, which not only destroys its tightness, but also increases the flow resistance. If the peeled carbon residue is taken out of the compressor, it will block the capillary tube and the dryer. The acid substances will corrode the components of the chiller refrigeration system and electrical insulation materials. Moisture will block the capillary.

4. Excessive exhaust temperature of the compressor will directly affect its service life, because the chemical reaction speed increases with the increase of temperature. In general, if the temperature of an electrical insulating material rises by 10°C, its life span is reduced by half. This is particularly important for hermetic compressors, and we need to deeply analyze and summarize. We must limit the discharge temperature of the special refrigeration compressor for chillers, so as to better promote the development of the industry.
