Room Air Conditioners

Regulatory Language for State Equipment Standards

Room air conditioners means consumer products, other than packaged terminal air conditioners (as described in section 506.4(d)(1)), which are powered by a single phase electric current and which are an encased assembly designed as a unit for mounting in a window or through a wall for the purpose of providing delivery of conditioned air to an enclosed space. They include a prime source of refrigeration and may include a means for ventilating and heating.

The minimum energy efficiency standards for room air conditioners shall be the levels set forth in the table below determined in accordance with the test procedures set forth in 10 Code of Federal Regulations (CFR) Part 430, Subpart B, Appendix F [(last amended June 29, 1979)] (see section 506.6 of this Part). [PDF] The minimum efficiency standards set forth in Table 5.5 shall apply solely to room air conditioners without reverse cycles, but with louvers.

*Energy Efficiency Ratio means the ratio of net cooling capacity in BTUs per hour to the total rate of electric input in watts, under designated operating conditions.
