Potential of Evaporative Cooling Systems for Buildings in India
MetadataShow full item record
Evaporative cooling potential for building in various climatic zones in India is investigated. Maintainable indoor conditions are obtained from the load - capacity analysis for the prevailing ambient conditions. For the assumed activity level, clothing and air velocity, the predicted mean vote (PMV), predicted percentage dissatisfied (PPD), and cumulative dissatisfaction levels for each month are estimated. Time - air condition contours of ambient, supply air and indoor air are plotted on a psychrometric chart for different cities in India like Ahmadabad, Jodhpur, Nagpur and New Delhi representing different climatic conditions of India. While satisfactorily comfort can be achieved at cool and dry weather conditions by evaporative cooling system throughout the year, some discomfort prevailed for few months around July at hot and dry/humid weather conditions. The results are also quantified in terms of PMV, PPD and their cumulative factors; PMV-hour and PPD-hour.
