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 4.1 for Methanol or Environol, 4.2 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
