Performance Standard (AI/ISO/ASAE 13256-2) The performance standard AI/ASAE/ISO 13256-2 became effective January 1, 2000. This new standard has three major categories: Water Loop, Ground Water, and Ground Loop. Unit of Measure: The Cooling COP The cooling efficiency is measured in EER (US version measured in Btuh per Watt. The Metric version is measured in a cooling COP (Watt per Watt) similar to the traditional COP measurement. Pump Correction Calculation Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following formula. This additional power is added onto the existing power consumption. Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300 Where gpm is waterflow in gpm and Press Drop is the pressure drop through the unit heat exchanger at rated water flow in feet of head. ISO Capacity and Efficiency Calculations The following equations illustrate cooling calculations: ISO Cooling Capacity = Cooling Capacity (Btuh) x 3.412 ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) x 3.412 / [ Input (Watts) + Pump Correction (Watt)] The following equations illustrate heating calculations: ISO Heating Capacity = Heating Capacity (Btuh) x 3.412 ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [ Input (Watts) + Pump Correction (Watt)] Test Conditions Conversions Water Flow (lps) = GPM x 0.0631 Press Drop (Pascals) = Press Drop (ft hd) x 2990 SD1900WW 11/13 4 Page of

The lowest flow rate shown is used for geothermal open loop/well water systems with a minimum of 50 F 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 F assumes 15% antifreeze solution. Interpolation between ELT, EST, and GPM data is permissible. Operation in the gray areas is not recommended.
