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