| Abstract | An alternate type of cooling, which does not use CFCs and consumes much less energy is highly desirable. The evaporative cooling can be employed with low energy consumption. These systems only suffer from a drawback of being less effective in humid climates. Some places like Delhi (India) where ambient conditions remain hot and dry in April and May but hot and humid in the months of June. For such a location direct or indirect evaporative coolers are effective in April and May but not effective in June. This paper examines the usefulness of a multistage evaporative cooling system for summer months. A room coupled with such a cooling system has been simulated to obtain diurnal hourly values of room air dry bulb temperature and relative humidity for summer months of April to June for Delhi. The results of simulation indicate that the proposed system can be operated in direct mode to provide thermal comfort in the month of April and May. Indirect - direct evaporative cooling system can be used to provide relief cooling in the month of June which is hot and humid. Keywords: Thermal comfort, multistage evaporative cooling |
