DESIGNING SYSTEMS TO USE SIMPLER EXPANSION DEVICES

摘要：

This paper describes the fundamental physics underlying the operation of fixed and variable expansion devices, and summarizes results of the analyses performed to compare them. Almost all the design options failed to match TXV system performance but for a few, the COP shortfall was less than 3％ at outdoor ambient temperatures ＞27℃. However at lower ambient temperatures the only configuration capable of matching TXV system performance employed a short tube orifice with low side receiver and internal heat exchanger.
