Rating procedure for mixed air-source unitary air conditioners and heat pumps operating in the cooling mode - revision 1

Published

Author(s)

Piotr A. Domanski

Abstract

A procedure is presented for determining the cooling performance ratings of air-source unitary air conditioners and heat pumps consisting of a condensing unit and an indoor section which were not tested together as a system. The procedure allows calculation of capacity at the 95°F rating point and seasonal energy efficiency ratio, SEER, using as a reference point performance ratings of the condensing unit tested under current DoE procedures in conjunction with a different indoor section. This procedure has been prepared for the Department of Energy for consideration in the rule making process. It is a revised version of the original version of the procedure published in 1986.
