4. HEAT OF REJECTION (HR) / HEAT OF EXTRACTION (HE) CALCULATION

HR or HE = Flow Rate x Temperature Difference x Brine Factor*
d. (above) x g. (above) x 485 for Methanol or Environol, 500 for water*
Heat of Extraction (Heating Mode) =

kW/hr

Heat of Rejection (Cooling Mode) =

kW/hr

Compare results to Capacity Data Tables

Note: Steps 5 through 8 need only be completed if a problem is suspected
