Heat stress associated with elevated temperatures and relative humidity (rh) has been shown to reduce the production levels of different swine facilities. Traditional cooling methods including evaporative pad cooling and misting have been used to lower temperature, but are not as effective in lowering relative humidity. Also, electric air-conditioning (AC) has been shown to be effective, but generally not as feasible an option due to more demanding cost and operational considerations. This study represents a first analysis of a space conditioning system that uses desiccants to control relative humidity and to enhance different cooling methods including evaporative pads. Desiccants have proved effective in human comfort applications when used in conjunction with traditional AC units. Results from this study suggest these systems could be used to effectively eliminate stress conditions in a swine facility or modified to enhance current cooling methods.
