Type of article: Article

Summary

THE HOURLY HEATING AND COOLING LOADS FOR 365 DAYS OF YEAR WERE CALCULATED BY SHASE. AS TO VAV SYSTEMS THE AA. STUDIED: ONE SYSTEM WAS THAT WHICH HANDLED TRANSMISSION LOADS WITH CAV (CONSTANT AIR VOLUME) AND SOLAR AND INTERIOR SPACE LOADS WITH VAV, AND THE OTHER WAS THAT WHICH HANDLED HEATING TRANSMISSION LOADS WITH RADIATORS UNDER THE WINDOWS AND OTHER LOADS WITH VAV. AS THE MINIMUM FLOW OF OUTLET AIR OF VAV SYSTEMS, TWO VALUES WERE SET AND COMPUTED RESPECTIVELY, THAT IS, 50% OF THE MAXIMUM FLOW RATE, AND THE GREATER ONE OF 25% OF THE MAXIMUM AND THE MINIMUM OUTSIDE VENTILATION AIR. AS THE BASIC AIR CONDITIONING ENERGY CONSUMPTION, THE AA. ADOPTED THE MEAN ENERGY CONSUMPTION OF 4-PIPE INDUCTION UNIT SYSTEM WHICH WAS CONSTANTLY INTAKING THE MINIMUM OUT DOOR AIR WITHOUT AIR TO AIR HEAT EXCHANGER DURING A WHOLE YEAR AS A RESULT, IN CASE OF USING AIR TO AIR HEAT EXCHANGER AND ADOPTING FREE AIR COOLING, VAV SYSTEM WITH RADIATORS OBTAINED THE MOST ONTROLLED BY SPEED FAN CONTROL AND SET BY THE ABOVE-MENTIONED LESS VALUE OF THE MINIMUM FLOW OF OUTLET AIR BECAUSE OF THE MINIMUM ENERGY CONSUMPTION THROUGH CARRIER POWERS.
