Summary

FOR THE COOLING AND HEATING OF A LARGE AIR SPACE, THE REGION SUBJECTED TO AIR CONDITIONING SHOULD BE RESTRICTED WITHIN THE OCCUPIED ZONE FROM THE VIEWPOINT OF ENERGY CONSERVATION. THE MAIN CONCLUSIONS OBTAINED BY MODEL EXPERIMENTS ARE AS FOLLOWS: 1) THE COLD AIR PROJECTED VERTICALLY FROM THE FLOOR LEVEL STAGNATES WITHIN THE MIDDLE HEIGHT OF AIR SPACE. THE AIR DISTRIBUTION IS UNIFORM WITHIN THIS REGION. 2) THE HEAT GAIN THROUGH WALLS IS REDUCED TO LESS THAN 80% COMPARED WITH THAT OF UNIFORM COOLING IN THE WHOLE AIR SPACE. 3) DEPRESSION OF HOT AIR CURRENT CAN BE SUCCESSFULLY DONE BY THE AIR CURTAINS PROJECTED HORIZONTALLY LOCATED AT THE UPPER PART OF THE OCCUPIED ZONE. THE MAXIMUM EFFECT OF AIR CURTAINS IS ATTAINED WHEN OUTLET VELOCITY IS ABOUT 7 M/S.
