<p>A system 10 for conditioning exterior air for use in a spray booth (14, fig 1) comprises a cooling coil 28, a pre-heater 26, a humidifier 30, a re-heater 32 and a controller (16, fig 2) that controls the cooling coil 28, pre-heater 26, humidifier 30 and re-heater 32 to adjust a dry bulb temperature and relative humidity of the exterior air to a variable set point based upon sensed atmospheric conditions (20, 22). The set point of the dry bulb temperature and relative humidity is selected to reduce an amount of energy required to condition the exterior air. The set point selection may be based upon future predicted weather conditions that are determined with a mathematical profile of previous weather conditions and weather trends in a localized domain. The localized domain may be a geographic area surrounding a manufacturing plant that includes the spray booth. The spray booth may be used for spray painting vehicles, paint other appliances or children's toys or used as a coating booth for applying coatings.</p> |
