Summary

STATES THAT FOR THE DESIGN OF DISPLACEMENT VENTILATION THE AMOUNT OF AIR TRANSPORTED IN THE CONVECTIVE AIR FLOWS NEEDS TO BE KNOWN, AS THEY ARE RESPONSIBLE FOR THE TRANSPORT OF AIR IN THE ROOM. FORMULAS GIVEN SO FAR ARE BASED ON RESULTS OBTAINED IN ROOMS WITHOUT TEMPERATURE GRADIENTS, BUT THE BASIS FOR DISPLACEMENT VENTILATION IS A TEMPERATURE GRADIENT. PRESENTS A SIMPLE METHOD FOR CALCULATING THE TEMPERATURE RELATIONS IN ROOMS WITH DISPLACEMENT VENTILATION. STATES THE CONVECTIVE AIR FLOW FROM COMMON HEAT SOURCES IN OFFICES HAS BEEN MEASURED FOR DIFFERENT GRADIENTS. STATES THE RESULTS SHOW THAT THE CONVECTIVE AIR FLOWS ARE INFLUENCED NOT ONLY BY THE GRADIENT BUT ALSO BY THE VENTILATION AIR FLOW.
