§ 429.15 Room air conditioners. ( a ) *Sampling plan for selection of units for testing.* ( 1 ) The requirements of § 429.11 are applicable to room air conditioners; and
( 2 ) For each basic model of room air conditioners, a sample of sufficient size shall be randomly selected and tested to ensure that— ( i ) Any represented value of estimated annual operating cost, energy consumption or other measure of energy consumption of a basic model for which consumers would favor lower values shall be greater than or equal to the higher of: ( A ) The mean of the sample, where: or,
( B ) The upper 971 ⁄ 2 percent confidence limit (UCL) of the true mean divided by 1.05, where: and
( ii ) Any represented value of the combined energy efficiency ratio (CEER) (determined in § 430.23(f)(3) for each unit in the sample) or other measure of energy consumption of a basic model for which consumers would favor higher values shall be less than or equal to the lower of: ( A ) The mean of the sample, where: or,
( B ) The lower 971 ⁄ 2 percent confidence limit (LCL) of the true mean divided by 0.95, where:
( 3 ) The cooling capacity of a basic model is the mean of the measured cooling capacities for each tested unit of the basic model, as determined in § 430.23(f)(1) of this chapter. Round the cooling capacity value to the nearest hundred.
( 4 ) The electrical power input of a basic model is the mean of the measured electrical power inputs for each tested unit of the basic model, as determined in § 430.23(f)(2) of this chapter. Round the electrical power input to the nearest ten.
( 5 ) Round the value of CEER for a basic model to one decimal place.
( b ) *Certification reports.* ( 1 ) The requirements of § 429.12 are applicable to room air conditioners; and
( 2 ) Pursuant to § 429.12(b)(13), a certification report shall include the following public product-specific information: The combined energy efficiency ratio in British thermal units per Watt-hour (Btu/Wh)), cooling capacity in British thermal units per hour (Btu/h), and the electrical power input in watts (W).
( 3 ) Pursuant to § 429.12(b)(13), a certification report for a variable-speed room air conditioner basic model must include supplemental information and instructions in PDF format that include— ( i ) The mean measured cooling capacity for the units tested at each additional test condition (*i.e.,* respectively, the mean of Capacity2, Capacity3, and Capacity4, each expressed in Btu/h and rounded to the nearest 100 Btu/h, as determined in accordance with section 4.1.2 of appendix F of subpart B of part 430 of this chapter);
( ii ) The mean electrical power input at each additional test condition (respectively, the mean of Power2, Power3, and Power4, each expressed in W and rounded to the nearest 10 W, as determined in accordance with section 4.1.2 of appendix F of subpart B of part 430 of this chapter); and
( iii ) All additional testing and testing set up instructions (*e.g.,* specific operational or control codes or settings) necessary to operate the basic model under the required conditions specified by the relevant test procedure.
