Investigation Into The Performance Of A Desiccant Cooling System Combined With Chilled Ceiling

The heat generated within a closed space like office has increased drastically in recent years with the optimal use of the heat generated equipment such as computer, and other machines. As air conditioning is an inherently energy intensive process, so there is a need for devising more efficien...
