Abstract:This document summarizes the evolution of the design of a 10 kW split system residential heat pump, to operate with R744 on the transcritical cycle. It is the first such prototype to be designed, and will be used for experimental purposes. The final design was influenced several factors, and tradeoffs were quantified by using our system simulation model, which was developed and validated using extensive experimental data from both residential and mobile ac systems. Several constraints prevented optimization of this particular design, including tube and fin dimensions and overall heat exchanger package dimensions. The numbers of serpentine passes were optimized by considering the total pressure drop and manufacturing processes.
