# §429.62. Portable air conditioners.

- (a) **Sampling plan for selection of units for testing.**
  - (1) The requirements of [§ 429.11](/cfr/10/429.11.md) are applicable to portable air conditioners; and
  - (2) For each basic model of portable air conditioner, a sample of sufficient size must be randomly selected and tested to ensure that—
    - (i) Any represented value of energy consumption or other measure of energy consumption of a basic model for which consumers would favor lower values is greater than or equal to the higher of:
      - (A) **The mean of the sample—** Or,
      - (B) The upper 95 percent confidence limit (UCL) of the true mean divided by 1.10:

        And,

    - (ii) Any represented value of the combined energy efficiency ratio or other measure of energy consumption of a basic model for which consumers would favor higher values is less than or equal to the lower of:
      - (A) **The mean of the sample—** Or,
      - (B) The lower 95 percent confidence limit (LCL) of the true mean divided by 0.90:

        And,

  - (3) When testing in accordance with appendix CC of [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter, the represented value of cooling capacity for a single-speed portable AC shall be seasonally adjusted cooling capacity (“SACC”) and the represented value of cooling capacity for a variable-speed portable AC shall be full-load seasonally adjusted cooling capacity (“SACCFull”), as determined in appendix CC to [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter. When testing in accordance with appendix CC1 to [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter, the represented value of cooling capacity for both single-speed and variable-speed portable ACs shall be SACC, as determined in appendix CC1 to [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter.
  - (4) Where SACC is used for representation, the represented value of SACC of a basic model must be the mean of the SACC for each tested unit of the basic model. Likewise, where SACCFull is used for representation, the represented value of SACCFull of a basic model must be the mean of the SACCFull for each tested unit of the basic model. When using appendix CC to [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter, round the mean SACC or SACCFull value to the nearest 50, 100, 200, or 500 Btu/h, depending on the magnitude of the calculated SACC or SACCFull, as applicable, in accordance with Table 1 of ANSI/AHAM PAC-1-2015, (incorporated by reference, see [§ 429.4](/cfr/10/429.4.md)), “Multiples for reporting Dual Duct Cooling Capacity, Single Duct Cooling Capacity, Spot Cooling Capacity, Water Cooled Condenser Capacity and Power Input Ratings”. When using appendix CC1 to [subpart B of part 430](/cfr/10/part430-subpartB.md) of this chapter, round SACC to the nearest 50, 100, 200, or 500 Btu/h, depending on the magnitude of the calculated SACC, in accordance with Table 1 of AHAM PAC-1-2022, (incorporated by reference, see [§ 429.4](/cfr/10/429.4.md)), “Multiples for reporting Dual Duct Cooling Capacity, Single Duct Cooling Capacity, Spot Cooling Capacity, Water Cooled Condenser Capacity and Power Input Ratings”.
  - (5) The represented value of combined energy efficiency ratio or annualized energy efficiency ratio of a basic model must be rounded to the nearest 0.1 Btu/Wh.
  - (6) Single-duct and dual-duct portable air conditioners distributed in commerce by the manufacturer with multiple duct configuration options that meet DOE's definitions for single-duct portable AC and dual-duct portable AC, must be rated and certified under both applicable duct configurations.
- (b) **Certification reports.**
  - (1) The requirements of [§ 429.12](/cfr/10/429.12.md) are applicable to single-duct and dual-duct portable air conditioners; and
  - (2) Pursuant to [§ 429.12(b)(13)](/cfr/10/429.12.md?p=b-13), a certification report shall include the following public product-specific information: The combined energy efficiency ratio (CEER in British thermal units per Watt-hour (Btu/Wh), the seasonally adjusted cooling capacity in British thermal units per hour (Btu/h), the duct configuration (single-duct, dual-duct, or ability to operate in both duct configurations), presence of heating function, and primary condensate removal feature (auto-evaporation, gravity drain, removable internal collection bucket, or condensate pump).
