Use fog spray system inside the wall to cool down the temperature, and add proper Pyroligneous acid into spray system to eliminate the ammonia. This method mainly uses the space inside the wall of the house to improve the environmental operation. The improvement process does not change environment factors such as temperature, humidity and wind speed rapidly, thus maintains better thermal environment managements to provide a cooler and stinkless livestock house environment The effects of cooling ability of spray pressure, operating time and rest time were discussed and the improvement effect is determined by THI(temperature-humidity index); addition to get rid of ammonia, discuss spray pressure, operating time and Pyroligneous acid dilution effect on the ammonia removal effects. Combine of these two strategies and then propose the best spray strategy. The best spray strategy of this facilities is spray pressure 50 kg/cm2, operating time of 25 seconds, rest time of 30 seconds and Pyroligneous acid dilution 100 times. This strategy can cool down the indoor temperature and remove ammonia. Meanwhile, we can provide a more comfortable livestock environment by using THI value as on /off condition.3966800 bytesapplication/pdfen-US豬舍複層牆噴霧去除氨氣溫濕度指數。swine barndouble-layer wallfog sprayingammonia removingtemperature-humidity indexthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/248536/1/ntu-99-R97622029-1.pdf
