Summary

The calculation algorithm for a multistage vapour-compression HPS, consisting of several calculation units, based on the compression stage, was developed. The calculation analysis was made for one, two, three and four stages of compression with consideration of limitations for the temperature of reverse water in the heat supply system. The effect of alteration of intermediate temperatures (pressures) of condensation at an intermediate stage was estimated. The technical-economic analysis included: determination of additional investments into the system of multistage compression; calculation of operation costs; determination of technical-economic characteristics for all closed heat power circuits and intermediate compression stage, where independent thermodynamic cycles occur; comparative analysis of efficiency for the systems with multistage compression.
