Energy Conservation Program: Test Procedures for Portable Air
Conditioners; Correction
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Final rule; correcting amendments.
-----------------------------------------------------------------------
SUMMARY: On June 1, 2016, the U.S. Department of Energy (``DOE'')
published a final rule adopting test procedures for portable air
conditioners (``June 2016 final rule''). A correction rule was
subsequently published on October 14, 2016 (``October 2016 correction
rule''), to correct typographical errors in the June 2016 final rule
that were included in the regulatory text. This document corrects
typographical errors introduced in the October 2016 correction rule,
including missing parentheses and incorrect variable names. Neither the
errors nor the corrections in this document affect the substance of the
rulemaking or any of the conclusions reached in support of the final
rule.
DATES: Effective April 20, 2020.

SUPPLEMENTARY INFORMATION:

I. Background
DOE published a final rule in the Federal Register on June 1, 2016,
establishing test procedures for portable air conditioners in appendix
CC to subpart B of Title 10 of the Code of Federal Regulations (CFR)
part 430 (``appendix CC''). 81 FR 35242. On October 14, 2016, DOE
published a correction rule that revised appendix CC to correct
typographical errors identified following the publication of the June
2016 final rule. 81 FR 70923. An additional correction rule was
published on February 21, 2019, to republish amendments that could not
be incorporated the Code of Federal Regulations due to inaccurate
amendatory instructions provided in the June 2016 final rule. 84 FR
5346. DOE subsequently identified typographical errors in appendix CC
that were introduced in the October 2016 correction rule. This
correction rule revises appendix CC to correct these typographical
errors.
Specifically, in section 4.1.2 of appendix CC, DOE is correcting
the following errors: Missing parentheses in the Qs_95 and
Qs_83 equations; extended underscore and capitalization in
the subscript for the variable cp_wv and missing underscore
for the variable [omega]ia_95 in the Qs_95
equation; and missing subscripts for the Ql_83 variable in
the Qinfiltration_83 equation. DOE is also clarifying in the
variable list for the Ql_95 and Ql_83 equations
that the ``60'' value represents the conversion factor from minutes to
hours.
II. Need for Correction
As published, the regulatory text in the June 2016 final rule as
corrected by the October 2016 and February 2019 correction rules may
result in confusion due to typographical errors in section 4.1.2 of
appendix CC. Because this final rule would simply correct errors in the
text without making substantive changes in the June 2016 final rule,
the changes addressed in this document are technical in nature.
III. Procedural Issues and Regulatory Review
DOE has concluded that the determinations made pursuant to the
various procedural requirements applicable to the June 2016 final rule
remain unchanged for this final rule technical correction. These
determinations are set forth in the June 2016 final rule. 81 FR 35242,
35260.
Pursuant to the Administrative Procedure Act, 5 U.S.C. 553(b), DOE
has determined there is good cause to find that notice and prior
opportunity for comment on this rule are unnecessary and contrary to
the public interest. Neither the errors nor the corrections in this
document affect the substance of the June 2016 final rule or any of the
conclusions reached in support of the final rule. Providing prior
notice and an opportunity for public comment on correcting objective,
typographical errors that do not change the substance of the test
procedure serves no useful purpose. Further, this rule correcting
typographical errors makes non-substantive changes to the test
procedure. As such, this rule is not subject to the 30-day delay in
effective date requirement of 5 U.S.C. 553(d) otherwise applicable to
rules that make substantive changes.

4.1.2. Infiltration Air Heat Transfer. Measure the heat
contribution from infiltration air for single-duct portable air
conditioners and dual-duct portable air conditioners that draw at
least part of the condenser air from the conditioned space.
Calculate the heat contribution from infiltration air for single-
duct and dual-duct portable air conditioners for both cooling mode
outdoor test conditions, as described in this section. Calculate the
dry air mass flow rate of infiltration air according to the
following equations:

single-duct portable air conditioners, in pounds per minute (lb/m).
m95 and m83 = dry air mass flow rate of
infiltration air for dual-duct portable air conditioners, as
calculated based on testing according to the test conditions in
Table 1 of this appendix, in lb/m.
Vco_SD, Vco_95, and Vco_83 =
average volumetric flow rate of the condenser outlet air during
cooling mode testing for single-duct portable air conditioners; and

conditioners, and at the 95 [deg]F and 83 [deg]F dry-bulb outdoor
conditions for dual-duct portable air conditioners, respectively, in
pounds mass per cubic foot (lbm/ft\3\).

conditioners, and at the 95 [deg]F and 83 [deg]F dry-bulb outdoor
conditions for dual-duct portable air conditioners, respectively, in
pounds mass of water vapor per pounds mass of dry air
(lbw/lbda).

humidity ratio of condenser inlet air during cooling mode testing at
the 95 [deg]F and 83 [deg]F dry-bulb outdoor conditions for dual-
duct portable air conditioners, respectively, in lbw/
lbda.
For single-duct and dual-duct portable air conditioners,
calculate the sensible component of infiltration air heat
contribution according to:
Qs_95 = m x 60 x [(cp_da x (Tia_95-
Tindoor)) + (cp_wv x ([omega]ia_95
x Tia_95-[omega]indoor x Tindoor))]
Qs_83 = m x 60 x [(cp_da x (Tia_83-
Tindoor)) + (cp_wv x ([omega]ia_83
x Tia_83-[omega]indoor x Tindoor))]
Where:
Qs_95 and Qs_83 = sensible heat added to the
room by infiltration air, calculated at the 95 [deg]F and 83 [deg]F
dry-bulb outdoor conditions in Table 1 of this appendix, in Btu/h.
m = dry air mass flow rate of infiltration air, mSD or
m95 when calculating Qs_95 and mSD
or m83 when calculating Qs_83, in lb/m.
cp_da = specific heat of dry air, 0.24 Btu/
lbm-[deg]F.
cp_wv = specific heat of water vapor, 0.444 Btu/
lbm-[deg]F.

Tia_95 and Tia_83 = infiltration air dry-bulb
temperatures for the two test conditions in Table 1 of this
appendix, 95 [deg]F and 83 [deg]F, respectively.
[omega]ia_95 and [omega]ia_83 = humidity
ratios of the 95 [deg]F and 83 [deg]F dry-bulb infiltration air,
0.0141 and 0.01086 lbw/lbda, respectively.
[omega]indoor = humidity ratio of the indoor chamber air,
0.0112 lbw/lbda.
60 = conversion factor from minutes to hours.
Calculate the latent heat contribution of the infiltration air
according to:
Ql_95 = m x 60 x Hfg x
([omega]ia_95-[omega]indoor)
Ql_83 = m x 60 x Hfg x
([omega]ia_83-[omega]indoor)
Where:
Ql_95 and Ql_83 = latent heat added to the
room by infiltration air, calculated at the 95 [deg]F and 83 [deg]F
dry-bulb outdoor conditions in Table 1 of this appendix, in Btu/h.
m = mass flow rate of infiltration air, mSD or
m95 when calculating Ql_95 and mSD
or m83 when calculating Ql_83, in lb/m.
Hfg = latent heat of vaporization for water vapor, 1061
Btu/lbm.

[omega]indoor = humidity ratio of the indoor chamber air,
0.0112 lbw/lbda.

The total heat contribution of the infiltration air is the sum
of the sensible and latent heat:
Qinfiltration_95 = Qs_95 +
Ql_95
Qinfiltration_83 = Qs_83 +
Ql_83
Where:
Qinfiltration_95 and Qinfiltration_83 = total
infiltration air heat in cooling mode, calculated at the 95 [deg]F
and 83 [deg]F dry-bulb outdoor conditions in Table 1 of this
appendix, in Btu/h.
