Legend and Notes Abbreviations and Definitions ELT = entering load fluid temperature to heat pump = leaving load fluid temperature from heat pump LPM = load flow in gallons per minute LWPD = load heat exchanger water pressure drop EST = entering source fluid temperature to heat pump LST = leaving source fluid temperature from heat pump SPM = source flow in gallons per minute SWPD = source heat exchanger water pressure drop EE = cooling energy effciency (T/KW) PSI = pressure drop in pounds per square inch FT HD = pressure drop in feet of head KW = kilowatt H = heat rejected in MBTUH T = total cooling capacity in MBTUH OP = coefficient of performance (H/KW x 3.413) H = heating capacity in MBTUH HE = heat of extraction in MBTUH Notes to Performance Data Tables The following notes apply to all performance data tables: Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water systems with a minimum of 50 EST. The middle flow rate shown is the minimum geothermal closed loop flow rate. The highest flow rate shown is optimum for geothermal closed loop systems and the suggested flow rate for boiler/ tower applications. Entering water temperatures below 40 assumes 15% antifreeze solution. Interpolation between ELT, EST, and PM data is permissible. Operation in the gray areas is not recommended.
