Chiller low pressure alarm

1. The low pressure of the chiller is very low, and the high pressure is very high, but there is no air leakage. At this time, check whether the temperature at both ends of the expansion valve and the filter dryer is consistent, or see whether the base of the expansion valve is frosty. Determine which part is blocked; Replace corresponding parts.

2. The high and low pressure of the chiller is lower than the normal value, and the leakage can be judged; Stop first, observe whether the water in the tank has bubbles, you can determine whether the evaporator is leaking.
