35Pumped Refrigerant System Operation and Maintenance
Path: Main > Cooling Modules > Select CM > Status > Overview
Temperature. The temperature at each of the sensors in the selected CM.
• Rack Inlet: The temperature of the air entering the rack at the remote temperature sensor.
• Supply Air: The average temperature of the air entering the CM as measured by the supply air
temperature sensors.
• Return Air: The average temperature of the air leaving the CM as measured by the return air
temperature sensors.
• Liquid In: The temperature of the pumped refrigerant entering the CM as measured by the liquid
refrigerant temperature sensor.
• Vapor Out: The temperature of the pumped refrigerant leaving the CM as measured by the vapor
refrigerant temperature sensor.
• Evaporator: The evaporation temperature of the refrigerant as it leaves the evaporator.
Pressures. The pressure sensor readings:
• Liquid In: The pressure of the pumped refrigerant entering the CM as measured by the liquid
refrigerant pressure transducer.
• Vapor Out: The pressure of the pumped refrigerant leaving the CM as measured by the vapor
refrigerant pressure transducer.
Valve Positions. The positions of the EEV and EPRV as expressed in a percentage of a full open
condition.
• EEV Pos: The current position of the Electronic Expansion Valve.
• EPRV Pos: The current position of the Electronic Pressure Regulator Valve.
