In the matter of: The**Tra~e** Co:

= the test procedure regulations by adding ,430.27 on September 26. 1980. creating the waiver process. 45 FR 64108. DOE further amended the Department's appliance te8t procedure waiver process to allow the Assistant Secretary for Conservation and Renewable Energy to grant an interim waiver from test procedure requirements to manufacturers that have petitioned DOE for a waiver of such prescribed product test procedures. 51 FR 42823, November 26. 1986. The waiver process allows the

.Assistant Secretary for Conservation and Renewable Energy to waive temporarily test procedures for a particular basic model when a petitioner shows that the basic model contains one or more design characteristics which prevent testing of the basic model according to the prescribed test procedures or when the prescribed test procedures·may evaluate the basic model in a manner so unrepresentative of its true energy consumption

. characteristics as to provide materially inadequate comparative data.

The Trane Company (Tr.ane) filed a "Petition for Waiver" dated March 10. 1987, in accordance with ,430.27 of 10 

### CFR Part 430. DOE published in the Federal Register Trane's petition and solicited comments, data. and infonnation respecting the petition. 52 FR 1'7315, May 7.1987. Trane subsequently filed an "Application for Interim Wai1{er" under' 430.27(g) and DOE wanted the Trane Company an interim waiver to central air «<onditioner test procedures. (Case No. CAC-003I). 52 FR 17198. May 12. 1987.

-

No comments were received concerning either the "Petition for Waiver" or the "Interim Waiver." DOE notified Trane by letter dated June 15. 1987; that no rebuttal was required. DOE GOUulted

### Assertions andDeterminations

Trane', petition Beeks a waiver from the DOE test provislonl thet require testing at a Bingle compressor lpeed. Trane was granted a waiver from the DOE test provisions that require testing 1ts TWS variable-speed model series heat pump in the cooling mode at 8 .ingle compressor speed on April1S, 1987. 57 FR 11855. (Hereafter referred to as the April Decision end Order.) Trane requests allowance to use DOE's proposed variable-speed test procedure. 51 FR 35736, October 7, 1986. including parts of Appendix B of the Air Conditioning and Refrigeration Institute (ARl) Standard 210/240-84 with certain modifications to determine the 

# unir. HSPF. Trane's petition requests that steady-state test points be at maximum, minimum. and "nominal capacity" speeds In order to accurately reflect the system's HSPF rating. One of the changes requested by Trane is that the frost/ defrost test run for HSPF. be run at the intermediate speed specified in the April Decision and Order for the cooling test with a tolerance of 

### ± 6-percent. Trane further requests to use DOE's proposed procedure for cyclic testing with both capacity and fan power integrated to the time determined by the units automatic controls. Trane also requests to use theARI Standard 2101 240-84 method of determining the heating part load factor instead of the DOE proposed procedure.

.

Trane identified its TWS variablespeed modeheries heat pump as using variable-speed motors to drive the compressor. indoor blower, and outdoor fan. The compressor is controlled over a wide range of speeds. Modulation of all three motors allows the system to meet specific building load requirements. The

.

. system operates at variable-speed using



### a microprocessor in conjunction with a special thennostat. 

### It was established in previous waiver evaluations concerning variabIe-speed heat pumps that the existing test and calculation method of Appendix M to Supart B of 10 

### CFR Part 430 were inappropriate. 

### The waiver granted to Carrier specified a test procedure that was based on Appendix B of ARl Standard 210/240-84. (Case
