ii. Cold Environment Temperatures Pumps Low Background Efficiency: To earn frigid weather Environment designation, heat heels must have shown lowest background show by conference next:
A main air conditioning equipment otherwise main air conditioning temperatures pump may include: A single-package product; an outdoor unit and something or maybe more indoor equipment; an inside product simply; or an outdoor tool no fits
- Policeman on 5 F ? step 1.75, measured relative to Appendix M15 H42 test.
- Per cent out-of Temperatures Capacity within 5F ? 70% of these at 47F, toward 5 F capability measured each Appendix M1 H42 ensure that you the fresh new 47F strength mentioned just like the moderate heating capability per Appendix M1 (i.elizabeth., on the Appendix M1 H1N try to own systems having an adjustable-rates compressor the spot where the compressor price are going to be the utmost speed your system control do jobs during the 47F, otherwise on Appendix M1 H12 shot)
- Do a regulation verification process (CVP) to ensure that the more than efficiency metrics counted from the Appendix M1 reasonable ambient sample point during the 5 F are achieved by the new indigenous control functioning while they manage within the a customer’s domestic.
Main Air conditioning equipment (CAC) otherwise Main Air conditioning Heat Push (HP) 1 : A product, aside from a packaged terminal ac unit otherwise packed terminal temperatures pump, that is run on single phase electric energy, air-cooled, rated lower than 65,000 Btu each hour, maybe not contains in the same closet while the a heater, the rated capability of which is actually a lot more than 225,000 Btu per hour, and is a hot-air push otherwise a cooling tool just.
