Abstract

The authors present an evaluation, analysis and comparison of several specific power electronic (PE)-based and non-PE based air conditioner and heat pump technologies, and their potential impact for energy savings on the Florida Power and Light Company system. Data and a computer flow chart are provided. Four heat pump models are developed and compared in regard to Florida climates. These models are conventional single-speed, two-speed, variable-speed, and Oak Ridge National Lab variable-speed systems. Some of the results indicate that, generally, the major advantage of PE-based variable-speed variable-capacity heat pumps is due to the higher coefficients of performance and energy efficiency ratios resulting from oversized heat exchangers, and the decrease of cycling losses that result from on/off operation which must occur when capacity exceeds load. >
