IEER INTEGRATED ENERGY EFFICIENCY RATIO Part load performance of commercial HVAC systems was represented as Integrated Part Load Performance (IPLV) which was used until January 1, 2010. Then a new methodology was adopted and defined as Integrated Energy Efficiency Ratio (IEER). IEER is intended to be used as a representation of part load performance for energy comparisons of similar systems. For Variable Refrigerant Flow (VRF) Multi Split systems AHRI Standard 1230 defines the process to calculate IEER. In its most simplistic form IEER is calculated by operating the system at 4 different capacities and applying a formula. The basic calculation is as follows: IEER = (0.02 * A) + (0.617 * B) + (0.238 * C) + (0.125 * D) Where as: A = EER at 100% net capacity at AHRI standard condition (95°F) B = EER at 75% net capacity and reduced ambient (81.5°F) C = EER at 50% net capacity and reduced ambient (68°F) D = EER at 25% net capacity and reduced ambient (65°F) Example: A = 11.0 EER B = 16.0 EER C = 19.0 EER D = 23.0 EER IEER = (0.02 * 11) + (0.617 * 16) + (0.238 * 19) + (0.125 * 23) IEER = 0.2 + 9.8 + 4.5 + 2.9 = 17.4 IEER Some points to recognize from this calculation: 1. Full load EER (100% capacity) represents only 2% of the overall IEER rating because the system would rarely operate at this condition. 2. As overall capacity is reduced the system EER increases significantly. 3. An ECOi system operating at 50% part load could result in an efficiency increase of more than 70% over the rated full load EER value. 4. Your actual efficiency could exceed the IEER rating depending upon equipment sizing, environment and use of the system.
