MIXTURES FOR THE ABSORPTION HEAT PUMP.

Author(s) : IEDEMA P. D.

Type of article: Article, IJR article

Summary

SOME EFFECTS OF KEY PROPERTIES OF THE MIXTURES DETERMINING THE HEAT PUMP PERFORMANCE ARE DESCRIBED, NOTABLY THE RATIO OF THE ENTHALPIES OF DILUTION AND EVAPORATION, AS WELL AS THEIR ABSOLUTE VALUES, THE DEVIATION FROM RAOULT'S LAW AND THE WORKING PRESSURE. A DESCRIPTION OF ONE-AND TWO-STAGE ABSORPTION HEAT PUMPS IS GIVEN AND A MODEL IS PRESENTED FROM WHICH HEAT RATIOS OF ONE-AND TWO-STAGE ABSORPTION HEAT PUMPS ARE CALCULATED FOR EIGHT MIXTURES. LOW PRESSURE MIXTURES APPEAR TO BE THE MOST FAVORABLE, SINCE THEY MAKE THE TWO-STAGE MACHINE FEASIBLE. FURTHER, BECAUSE OF ITS LOW FREEZING POINT, METHANOL IS PREFERABLE TO WATER AS A WORKING FLUID.
