Summary

A MULTI-STAGE REFRIGERATION-HEAT PUMP SYSTEM TO PRODUCE BOTH COOLING AND HEATING FOR INDUSTRIAL APPLICATIONS IS AN INTERESTING POSSIBILITY. SUCH REFRIGERATION-HEAT PUMP SYSTEMS ON WORKING FLUIDS R12, R22 AND R717 HAVE BEEN OPTIMIZED NUMERICALLY. OPTIMUM INTER-STAGE TEMPERATURES, COP, COMPRESSION RATIOS, HEATING AND COOLING EFFECTS AND REFRIGERANT MASS HANDLED BY HIGH PRESSURE COMPRESSOR HAVE BEEN PRESENTED FOR CONDENSING TEMPERATURES OF 293, 313 AND 333 K (20, 40 AND 60 DEG C) AND EVAPORATING TEMPERATURES OF 278 TO 228 K (5 TO -45 DEG C) IN 5 K INCREMENTS.
