Review of Passive Downdraught Evaporative Cooling Technique and its Application

Abstract:

Article Preview

Direct evaporative cooling has long been demonstrated as an energy efficient ,cost effective and no CFCs emission means for space cooling in hot dry regions .With the aggravating of the global climate warming and energy crisis, using passive cooling technique will be a good solution . In this paper, the theory of passive downdraught evaporative cooling techniques is analyzed. It is an environmental friendly technique in that it can provide more fresh air than the conventional air-conditionings, and also low cost on operation and no CFCs emission compared with conventional air-conditionings. In this paper, some cases will be introduced .The successful PDEC cases in hot dry areas show weather condition is the key factor for the feasibility using PDEC technique. From the analysis on the weather data in Turpan, which presents a typical climatic character in North-west China , predicts a great feasibility of using PDEC technique in public architectures.
