Influence of Excessive Exhaust Temperature of Industrial Chiller

The exhaust temperature of the industrial chiller is an important parameter in the operation of the equipment, and the user needs to strictly control it. If the discharge temperature is too high, it will cause overheating of the chiller compressor. Next, we describe the effect of high exhaust gas temperature on equipment during operation.

1. The high exhaust temperature of the compressor will directly reduce the gas transmission coefficient, increase the shaft power, and reduce the viscosity of the lubricating oil, which will cause abnormal wear on the bearings, cylinders and piston rings.

2. Once the exhaust temperature of the compressor is too high, it will directly lead to thermal decomposition of lubricating oil and refrigerant under the catalysis of metal, and generate acid substances, free carbon and moisture that are harmful to the compressor. Free carbon is deposited on the exhaust valve, which not only destroys its sealing performance, but also increases the flow resistance. If the exfoliated carbon residue is carried out, it will block the capillary and the dryer. Acids will corrode the components and electrical insulating materials of the chiller refrigeration system.

3. The operator should check the overheating of the compressor. If the overheating is serious, the piston will be over-expanded and stuck in the cylinder, and it will also cause the built-in motor of the hermetic compressor to burn out.

4. During the operation of the industrial chiller system, the pressure at the inlet is small and cannot meet the basic conditions of operation, and there will be a problem of inability to start.

5. According to the factory configuration manual, it can be understood that this problem is basically caused by the idling of the water pump and other reasons. As long as the air in each system is released, it can meet the operating environment suitable for the equipment.

After the failure of different degrees, the user needs to complete the maintenance of the equipment according to the actual needs. If the system still cannot operate normally, the user needs to contact the chiller manufacturer for replacement and maintenance in time.
