This research was to study the changes of temperature and humidity in silk worm rearing house by using an evaporative cooling system in combination with a vapor compression air conditioning system. This study was tested in greenhouse with configuration of 10 x 21 x 3 m. For evaporative cooling system, six sections of evaporative cooling of 1.5 x 1.8 x 0.15 m each were installed on the south wall of the house and six exhaust fans with diameter of 30 inches were installed on the north wall of the house. For the vapor compression cooling system, four air conditioners of 30,000 Btu/hr were used. The experimental results from the house with evaporative cooling for worm periods 1, 2 and 3 found that the average differences of suitable temperature for those worms were 0.4oC, 1.0oC and 1.9oC, respectively. For the relative humidity, the average differences were 6.09%, 0.61% and 3.29%, respectively. The experimental results from the house with the vapor compression cooling system for worm periods 4 and 5 found that the average differences of appropriate temperature and humidity were 2.2oC, 0.33% for worm period 4 and 3.1oC ,4.86% for worm period 5.
