EFFECT OF SATURATION EFFICIENCY OF DIRECT EVAPORATIVE COOLER ON INDOOR CONDITIONS AND THERMAL COMFORT IN A SMALL OFFICE ROOM OF A BUILDING

摘要

Thermal comfort of occupants and indoor air relative humidity (RH) in an office have been assessed through simulation study. In order to maintain room relative humidity below 65%, the requirement of cooler saturation efficiency and air change rate have been determined for some practical situations. It is observed that, it is not always desirable to have cooler with higher saturation efficiency for applications where low indoor air relative humidity is of primary concern. For such applications, an ordinary evaporative cooler having lower saturation efficiency (60%) may be used by allowing slightly higher air change rate inside the occupied space.
