Abstract:
The purpose of this report is to establish the method for determining the cooling performance ratings of air-source unitary split system air conditioners and heat pumps consisting of an outdoor section and an indoor section that were not tested together as a complete system. The quantities calculated in this document are the cooling capacity at the A Test conditions and the SEER as prescribed by the U.S. Department of Energy in Appendix M to Subpart B of Part 430 within Title 10 of the Code of Federal Regulations (CFR 2006a and CFR 2006b) and by ARI Standard 210/240 (ARI 2006).
Keywords: Unitary Air Conditioners and Heat Pumps, Mixed Systems, Matched Systems, Linear Cooling Capacity, Linear Power, SEER, Capacity Correction.
