Energy modeling Chiller at AHRI conditions LEEDuser

Mar 10, 2020 It comes down that the provider has sent us the chiller specs, and the chiller efficiency was tested at no AHRI conditions (COP and NPLV). Now appendix G specifies that proposed and baseline chillers should be modeled at AHRI conditions. So what I did was to recalculate the standard COP for the proposed chiller with the Kadj procedure (ASHRAE ...
