Energy Efficiency Ratio (EER) of a federally regulated consumer product

means the ratio of the average rate of space cooling delivered to the average rate of electrical energy consumed by the central air conditioner or heat pump. These rate quantities must be determined from a single test or, if derived via interpolation, must be determined at a single set of operating conditions. EER is expressed in units of Btu/watt-hour, as 10 C.F.R. section 430.23(m) (Appendix M to subpart B of part 430). When determined for a ducted coil-only central system, EER must include the section 3.3 and 3.5.1 default values for the heat output and power input of a fan motor found in 10 C.F.R. section 430.23(m) (Appendix M to subpart B of part 430)..
