Compared to the p R22 system, the R717 system has lower mass flow rate, lower work, higher cooling effect and higher coefficients of performance. 9b 3 Multistage Vapour Compression Heat Pumps for Drying The multistage vapour compression heat pump system has more components, but has the benefit of superior performance in a wider pressure range and temperature lift than single-stage vapour compression. A particular difference is that the multistage heat pump has two or more compressors and throttling devices operating at three or more temperature and pressure levels.

Then, the fluid enters the condensers and change phase to saturated liquid at point 3. From this point, the saturated liquid is throttled to a liquid and vapour mixture at point 4. After evaporation, the mixture becomes saturated vapour at point 1 to be compressed again. The processes in this cycle are as follows: 1–2: Isentropic compression of the saturated vapour to superheated vapour 2–3: Isobaric condensation of the superheated vapour to saturated liquid 3–4: Adiabatic expansion of the saturated liquid to vapour–liquid mixture 4–1: Isothermal–isobaric evaporation of the mixture to saturated vapour.

5 shows the main parameters to compare characteristics and performances of the basic vapour compression heat pump with dry-expansion evaporator ­operating with R717 and R22. 58 The basic vapour compression heat pump with dry-expansion evaporator has high c­ oefficients of performance for evaporating and condensing temperatures of 5°C and 40°C. The system with R717 has the benefits of lower mass flow rate, higher cooling effect and slightly higher coefficients of performance compared to the R22 system.
