AIR CONDITIONING IN OFFICE BUILDING WITHOUT A REFRIGERATION UNIT.

Author(s) : HUTTER E., VILLAIN J., DUCROTOY H.

Summary

RESEARCH IS BEING CONDUCTED INTO DOUBLE-FLOW AIR COOLING SYSTEMS WITHOUT A REFRIGERATION UNIT. THE OPERATING PRINCIPLE IS AS FOLLOWS: THE BUILDING IS VENTILATED AT NIGHT SO THAT COOL OUTSIDE AIR MAY LOWER THE TEMPERATURE OF THE STRUCTURE AND REDUCE THE HEAT ACCUMULATED DURING THE DAY. AT THE SAME TIME, COLD AIR IS PRODUCED BY ADIABATIC HUMIDIFICATION OF THE RETURN AIR AND EXCHANGE WITH OUTSIDE AIR. THE STUDY INVOLVES CHARACTERIZATION OF THE EFFICIENCY OF SUCH SYSTEMS AND THEIR CONTROLS, BY NUMERICAL SIMULATION. IT INVOLVES THE DETERMINATION OF A COMFORT CRITERION TO CLASSIFY THE DIFFERENT TECHNICAL SOLUTIONS. THE COMPATIBILITY OF REQUIREMENTS FOR WINTER AND SUMMER, THE BEHAVIOUR OF AIR DIFFUSERS, CONTROL SYSTEMS,THE COMFORT OF THE OCCUPANTS (AIR VELOCITY, GRADIENT) AND NOISE LEVELS ARE EXAMINED.
