This report describes a laboratory evaluation to optimize the performance and efficiency of a packaged air-conditioning and heating roof top unit (RTU) with a variable speed electrically communicated motor (ECM) controlling the blower speed and a retrofitted variable speed drive controlling the compressor speed. This technology is being considered as a method to save energy associated with air conditioning at part load conditions. It also may have potential to reduce peak electricity demand in buildings with over-sized equipment or when combined with condenser-air evaporative pre-cooling technology.
