increasing refrigerant pressure in the coil increasing chilled water flow through the cooler sub-cooling the refrigerant in the condenser superheating the refrigerant in the compressor
Proper refrigerant charge Faulty expansion valve Insufficient refrigerant Solenoid valve stuck open
too much refrigerant in the system oil entrained in the refrigerant less than a full charge of refrigerant in the system ice crystals forming in the refrigerant
higher boiling temperature for a given pressure than does a pure refrigerant lower boiling temperature for a given pressure than does a pure refrigerant boiling pressure equal to that of a pure refrigerant at a given pressure boiling point will not be affected by entrained oil

At the designed operating temperature, the liquid refrigerant charge has changed toa vapor The liquid refrigerant tends to collect at the bellows or diaphragm and reduces thevalve sensitivity The sensing bulb is empty of liquid refrigerant charge at the designed operatingtemperature The sensing bulb is never emptied of liquid refrigerant under normal operatingconditions
reclaims water purges air without losing refrigerant purges air with some loss of refrigerant purges lube oil from the refrigerant
