This study investigated the feasibility of using an evaporative cooling system to improve silkworm rearing house conditions. The inside air temperature was 3 °C lower than the open-air temperature in the silkworm rearing house obtained using a mist cooling system. When using a portable pad-and-fan cooling system, the half-room temperature was 2.5 °C lower. By contrast, when using the two portable pad-and-fan cooling system, the whole-room temperature was 4 °C lower. However, the temperature at a distance from a portable pad-and-fan cooling system was 1 °C higher than it was near the system. The relative humidity increased to 80% under these evaporative cooling systems in the silkworm rearing house, with no harmful effect observed on silkworm rearing. Therefore, these evaporative cooling systems indicate the possibility of preventing high-temperature injury during silkworm rearing.
