Abstract: This write-up contains air temperature data and preliminary analysis of cooling requirement for greenhouse at Bhujodi. Examination of the temperature data showed that night time temperatures remain high enough most of the time. Heating of the greenhouse perhaps will not be required. Day time temperatures on the other hand, remains high enough most of the time to require cooling. Forced ventilation does seem effective, but only for part of day. Evaporation cooling and misting appears necessary. Design of fan-pad system was carried out. It consists of two fans (size 24 inch and 1/3 HP) and cross fluted pad (area 5m2). Water loss is estimated to be about 1000 lit/day in the cooling system, which works out to about 10 lit/m2 of floor are per day.
