Computer simulation analysis was made for theoretical thermal characteristics of two stage compression two stage condensation cycle, which is one of the basic cycles of multistage heat pump systems, and steady state solution of convergence was obtained, component characteristics being replaced by simplified experimental models. Also experiments were performed by cycle simulation system using R22 as a working fluid and the steady results of measurements were obtained. Useful information for the design and estimation of multistage heat pump systems were obtained, by the consideration of the effect of the change for the performance parameters of condensation temperature, working fluids, condensation pressure ratio on the cycle characteristics.
