Full Description

The objective of this paper is to present the results of a review of several emissions testing standards that could potentially be used to standardize emissions measurements from unitary combustion engine-driven heat pumps (UCEDHPs) (Chapman and Gorder 1997). Existing emissions standards generally characterize emissions from stand-alone engines and do not apply to complete appliances. Consequently, portions of standards were selected as add-ons to the existing UCEDHP performance standard, ANSI Z21.40.4, Performance Testing and Rating of Gas-Fired, Air-Conditioning and Heat Pumping Appliances (ANSI 1994) to develop the emission testing procedure (ETP). The ETP was developed to minimize the economic impact on the UCEDHP industry while still meeting possible forthcoming requirements of the regulatory agencies.
