Seasonal Average Cooling COP (IPLV.SI)

Can be converted to Seasonal Average EER by conversion factor 3.412. For example, a COP of 6.207 (w/w) = EER 21.18 (btu/w).

Capacity, IPLV and NPLV certified in accordance with the AHRI Air-Cooled Water-Chilling Packages Certification Program, which is based on AHRI Standard 550/590 (SI) Certified in accordance with the AHRI Air-Cooled Water-Chilling Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). Full speed cooling performance map is derived from AHRI certified data, reformatted to include IP values. Heating COP and SCOP is certified by TUV under EN14825 inclusive of EN14511-2, EN14511-3, EN50564. Certain kW/kW values (Si, COP) are converted to EER values (IP, BTUh/W) using the standard conversion factor of 3.412 for convenience.
