Author(s) : HOLLAND F. A., WATSON F. A.

Type of article: Article

Summary

EQUATIONS ARE PRESENTED WHICH RELATE THE PAYBACK PERIOD OF A HEAT PUMP SYSTEM TO THE FIXED CAPITAL COST, THE ANNUAL USAGE FACTOR, THE UNIT COST OF INPUT ENERGY AND THE ACTUAL COP. THE LATTER IS RELATED TO THE THEORETICAL RANKINE COEFFICIENT OF PERFORMANCE BY A FACTOR WHICH DEPENDS UPON THE DESIGN OF THE PARTICULAR HEAT PUMP SYSTEM. FOR A GIVEN CONDENSING TEMPERATURE OF THE WORKING FLUID AND COMPRESSION RATIO, THE GROSS TEMPERATURE LIFT AND THE THEORETICAL RANKINE COP ARE FIXED FOR A PARTICULAR WORKING FLUID. THE SENSITIVITY OF THE RELATION-SHIP BETWEEN PAYBACK PERIOD AND ACTUAL COP TO FIXED CAPITAL COST AND INPUT ENERGY COST IS ILLUSTRATED GRAPHICALLY.
