HEATING CYCLE ANALYSIS
COOLING CYCLE ANALYSIS
HEAT OF EXTRACTION (ABSORPTION) OR HEAT OF REJECTION =
FLOW RATE (GPM) x
TEMP. DIFF. (DEG. F) x
FLUID FACTOR* =
(Btu/hr)
SUPERHEAT = SUCTION TEMPERATURE – SUCTION SATURATION TEMPERATURE
=
(DEG F)
SUBCOOLING = DISCHARGE SATURATION TEMPERATURE – LIQUID LINE TEMPERATURE
=
(DEG F)
*Use 500 for water, 485 for antifreeze.
