HEAT OF EXTRACTION (ABSORPTION) OR HEAT OF REJECTION =
FLOW RATE (gpm) x TEMP. DIFF. (DEG. F) x FLUID FACTOR* =
(Btu/hr)
SUPERHEAT = SUCTION TEMPERATURE – SATURATED SUCTION TEMPERATURE
=
(DEG F)
SUBCOOLING = SATURATED CONDENSING TEMPERATURE – LIQUID LINE TEMPERATURE
=
(DEG F)
*Use 500 for water, 485 for antifreeze.
