Calculating chiller emissions and source energy use
- Bevilacqua-Knight, Inc., Oakland, CA (United States)
Various analyses have compared the emissions and over-all source energy use of different chillers. However, these analyses are typically based on national or regional electric power plant annual averages or rely on outdated emissions data that do not account for scrubbers and other pollution controls applied in response to the 1990 Clean Air Act Amendments (CAAA). Other analyses have used power generation data for a specific utility but require hourly generation profiles, which are difficult to obtain. Thus, many of the existing models are either too general to provide valuable information or too complex to be practical for the day-to-day applications engineers face. This paper introduces a simple yet reliable hand calculation method for estimating the combustion-related emissions and source energy use of gas and electric chillers. The user needs to supply only two inputs: annual chiller system energy use and the utility`s power generation mix during chiller operation. The analysis supplies electric power plant heat rates and emission factors. Referenced guidelines are documented for all calculation inputs.
