![]() ![]() It should read significantly higher that the suction pressure gauge. ![]() If the compressor comes on, allow it to pump down the residual refrigerant left in the chiller before energizing the liquid line solenoid. If in addition the indicator in the liquid line sight glass shows.Īssure that the water in the tank is circulating through the chiller only (on bypass valves left open) and that the condenser pump is running raw seawater through the condenser. If the suction gauge reads zero, even though there is pressure reading on the discharge gauge, there might be a leak in the chiller. If they all read zero, the system refrigerant charge has leaked out. Some residual refrigerant pressure should read on the gauges. If oil is not visible in the compressor sight glass, dont start the compressor until you can add more.Īlso check pressure gauges, paying particular attention to the suction pressure gauge. Keep in mind that refrigeration oil is highly refined and under normal operation conditions is very pale yellow. If you cant see a level it is sometimes difficult to tell if the crankcase oil level is low or is overfilled. If the unit has been off for an extended period, energizing the heater overnight is good practice. On some units the heater is energized when the control power circuit breaker is made. Condenser shell cooler evaporator shell warmer (Centrifugal Chiller) at low condensing temperatures, refrigerant migrates to evaporator 20.ĭecreasing condenser water flow, which decreases the heat exchange capacity of the condenser, increases the compressor discharge pressure. ![]()
