ANALYSIS OF GAS FIRED ENGINE DRIVEN HEAT PUMP SYSTEMS.

Author(s) : PATANI A., BONNE U.

Summary

THE HEAT PUMP MODEL DEVELOPED PREVIOUSLY WAS EXPANDED FOR COOLING MODE ANALYSIS. INCORPORATED INTO THE MODEL WERE THE INFLUENCES OF CYCLING AND INFILTRATION ON SENSIBLE AND LATENT CAPACITY AND INDOOR RELATIVE HUMIDITY. ELECTRIC FAN CONSUMPTION APPEARS TO BE A MAJOR FACTOR DETERMINING SEASONAL SYSTEM OPERATING COSTS. HUMIDITY CONTROL BY SPEED MODULATED SYSTEMS WAS FOUND TO BE POORER, ESPECIALLY AT LOW LOADS, BECAUSE OF MODULATED MASS-FLOWS AND CONSEQUENT HIGHER EVAPORATING TEMPERATURES. THE ANNUAL PERFORMANCE WAS ALSO ANALYZED, AND THE OPTIMUM ENGINE-COMPRESSOR SPEED FOR THE SYSTEM STUDIED WAS FOUND TO BE DIFFERENT FOR HEATING AND COOLING MODES.
