Summary

A NUMERICAL COMPUTER MODELLING BASED ON THE SOLUTION OF SIMULTANEOUS HEAT AND MASS BALANCE EQUATIONS FOR VARIOUS COMPONENTS OF THE SYSTEM HAS BEEN CARRIED OUT. THE INFLUENCES OF COMPONENT TEMPERATURES AND HEAT EXCHANGER EFFECTIVENESS ON THE HEATING COP AND HEAT TRANSFER RATES HAVE BEEN INVESTIGATED TO OBTAIN OPTIMUM OPERATING CONDITIONS FOR THE PROPOSED HEAT PUMP SYSTEM. FURTHER, THE ABSORPTION CYCLES ARE COMPARED WITH AN IDEAL REVERSIBLE CYCLE OPERATING OVER THE SAME RANGE OF TEMPERATURES. THE PERFORMANCE OF THE ABSORPTION CYCLE DOES NOT CONTINUE TO IMPROVE AS THE INPUT TEMPERATURE INCREASES AND ADDITIONAL COMPONENTS WILL BE REQUIRED TO ALLOW THE MACHINE TO TAKE ADVANTAGE OF THE HIGHER TEMPERATURES AVAILABLE FROM MODERN COLLECTORS.
