Abstract

This study was conducted to assess performances of the developed environmental control systems under various seasons of Korea. In all trials for the environmental control systems, the manure pit ventilation system in the windowless pig-housing with partly slatted floor was used. Consequently, under all seasons of Korea, the complex environmental control systems could comfortably maintain the indoor temperature (14.8~27.2$^{\circ}C$) , concentrations of noxious gases (CO2 gas : 631~1,874ppm, NH3 gas : 0.3~3.2ppm), air velocity (0.11~0.23m/s), air movement, and so on. Therefore, the performances of the complex environmental control systems were evaluated as proper as the intended.
