Summary

IN AN AIR CONDITIONED ROOM WHERE PERIMETER HEATING AND INTERIOR COOLING ARE APPLIED SIMULTANEOUSLY, HEAT LOSS (MIXING ENERGY LOSS) OFTEN OCCURS MAINLY BECAUSE OF THE MIXING OF HEATED AND COOLED AIR JETS. THE PURPOSE OF THE PRESENT STUDY IS TO CLARIFY THE QUALITATIVE AND QUANTITATIVE MECHANISM OF SUCH LOSSES. EXPERIMENTS WERE PERFORMED WITH ACTUAL SIZE EQUIPMENT. THE MAIN RESULTS OBTAINED ARE: THE CONTROL TEMPERATURE DIFFERENCE BETWEEN THE PERIMETER AND THE INTERIOR HAS THE GREATEST INFLUENCE. THE LOWER IS THE CONTROL TEMPERATURE OF THE FORMER, THE LESS IS THE MIXING LOSS ; INORDER TO DIMINISH ENERGY LOSS, IT IS EFFECTIVE TO USE PANEL-HEATING TOGETHER WITH AN AIR OR WATER SYSTEM IN THE PERIMETER.
