COOLING CYCLE ANALYSIS -
Heat of Extraction (Absorption) or Heat of Rejection =
________ flow rate (
= Suction temperature - suction saturation temp.
Superheat
=
Subcooling Discharge saturation temp. - liquid line temp.
†
Use 500 for water, 485 for antifreeze.
Note: Never connect refrigerant gauges during startup procedures. Conduct water-side analysis
using P/T ports to determine water flow and temperature difference. If water-side analysis shows
poor performance, refrigerant troubleshooting may be required. Connect refrigerant gauges as a
last resort.
