(f) Room air conditioners and portable air conditioners. The capacity for room air conditioners shall be the cooling capacity in Btu per hour, as determined according to appendix F to 10 CFR part 430, subpart B, but rounded to the nearest value ending in hundreds that will satisfy the relationship that the energy efficiency value used in representations equals the rounded value of capacity divided by the value of input power in watts. If a value ending in hundreds will not satisfy this relationship, the capacity may be rounded to the nearest value ending in 50 that will. The capacity for portable air conditioners shall be determined according to appendix CC to 10 CFR part 430, subpart B, with rounding determined in accordance with 10 CFR part 430.
