Carrier Aquazone 50PCH007 Installation, Start-Up And Service Instructions Manual page 59

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.
