Study on performance evaluation of heat pump cycles: analysis of ideal Rankine cycles for multistage systems.

[In Japanese. / En japonais.]

Type of article: Article

Summary

Three ideal heat pump cycles of two-stage compression with two-stage expansion, three-stage compression with single-stage expansion and three-stage condensation systems, all of which are considered as performance improvement methods, were analyzed by introducing the evaluation formula of COP, and the physical property of working fluids. Temperature lift, condensation temperature, COP, working fluids and cycle name were taken as the analysis parameters. No losses for compressors, evaporator and condenser were assumed for ideal cycles. Analytical results were processed for graphical presentation and data bases were set up for the performance comparison and evaluation of multistage systems.
