AMELIORATION OF THERMAL COMFORT IN DRY TR OPICAL CLIMATE BY USE OF ANECONOMIC-PROCESS - DIRECT EVAPORATIVE COOLING

The characteristics of a dry tropical climate are given; the needs of economic equipment for air cooling are outlined from climatic data and local financial possibilities. It is shown that in this climatic zone , an acceptable thermal comfort can be obtained all year round by dire ct evaporative cooling of outside air. Experimental results obtained b y testing a direct evaporative cooler built locally at a cost compatib le with local incomes are given. However,for best thermal comfort, the use of both a direct evaporative cooler and some techniques of passiv e cooling must be done.
