DEVELOPMENT AND USE OF A MATHEMATICAL MODEL OF AN ENGINE-DRIVEN HEAT PUMP.

Author(s) : RUSK R. P.

Summary

A MODEL OF AN ENGINE-DRIVEN HEAT PUMP HAS BEEN DEVELOPED, CONSISTING OF 2 PARTS, AN ENGINE MODEL AND A HEAT PUMP MODEL. THE MODEL WAS USED TO CALCULATE THE SEASONAL COP DURING AN AVERAGE HEATING SEASON FOR A TYPICAL ENGINE-DRIVEN HEAT PUMP LOCATED IN 2 DIFFERENT CLIMATES (DES MOINES, IOWA, AND DALLAS, TEXAS). THE EFFECTS OF ENGINE SIZE AND ENGINE-TO-COMPRESSOR SPEED RATIO ON SEASONAL COP WERE CALCULATED. THE ENERGY COSTS OF OPERATING AN ENGINE-DRIVEN HEAT PUMP AND AN ELECTRIC-MOTOR-DRIVEN HEAT PUMP WERE COMPARED. USING TYPICAL RESIDENTIAL GAS AND ELECTRIC RATES, IT WAS FOUND THAT VARIABLE-SPEED OPERATION IS MORE ECONOMICAL FOR ELECTRIC HEAT PUMPS BUT CONSTANT-SPEED OPERATION COULD BE MORE ECONOMICAL FOR GAS-ENGINE-DRIVEN HEAT PUMPS.
