What Problems Can Be Caused By Low Pressure Failure of Chillers?
1. Increased energy consumption If the compressor is running at low pressure, the motor load will become smaller, and a chiller with a low-pressure failure will waste electricity under the same cooling conditions. 2. Smaller cooling capacity If the chiller suction pressure is low and the return air volume is reduced, the cooling capacity will not reach the target. What are the causes of low chiller pressure? How to solve? 1. Insufficient refrigerant or leakage Insufficient refrigerant will lead to system pressure failure, resulting in lower suction pressure. The chiller will issue a low pressure alarm and the unit will stop. Solution: The refrigerant leakage part can be diagnosed from the piping connection of compressor, condenser, filter, expansion valve, evaporator and other accessories. After troubleshooting, charging the right amount of refrigerant can solve the problem. Water Cooled Screw Chiller 2. Low ambient temperature When the outside temperature is low, the tempera
