Summary

THE PURPOSES OF THE STUDY ARE TO DISCLOSE THE MECHANISM OF THE ENERGY LOSS AND TO ESTABLISH THE OPTIMUM DESIGN METHODS OF AIR-DIFFUSION DEVICES AND THE CONTROL DEVICES IN THE SIMULTANEOUS HEATING AND COOLING SYSTEM. THE RESULTS ARE SUMMARIZED AS FOLLOWS: 1) THE TYPES OF INTERIOR OUTLETS INVESTIGATED ARE THE ANEMOSTAT DIFFUSER, RADIAL-FLOW OUTLET AND RECTANGULAR GRILL. THE GRILL MOUNTED ON THE HIGH SIDEWALL BROUGHT THE LARGEST AMOUNT OF ENERGY LOSS ; 2) IT WAS CONFIRMED THAT THE CONTROL-TEMPERATURE DIFFERENCE BETWEEN THE PERIMETER AND THE INTERIOR HAD THE GREATEST INFLUENCE ON ENERGY LOSS ; 3) THE HEAT STORAGE LOAD IN THE FLOOR SLAB HAD ALMOST NO EFFECT ON ENERGY LOSS, BUT IT HAS GREAT INFLUENCE ON THE THERMAL COMFORT OF OCCUPANTS ; 4) AMONG LOCATIONS OF THE PERIMETER THERMOSTAT, THE FRONT POSITION OF THE FAN-COIL UNIT BROUGHT THE MOST DESIRABLE EFFECTS AND THE INLET POSITION OF THE FAN-COIL UNIT BROUGHT THE MOST DISADVANTAGEOUS EFFECTS ON ENERGY LOSS RIBUTION.
