INTELLIGENT AIR CONDITIONING SYSTEM FOR A PAINT BOOTH
First Claim
1. A method for conditioning exterior air for a spray booth, comprising the steps of:
- sensing dry-bulb temperature of the exterior air;
sensing relative humidity of the exterior air;
selecting a set point that has a particular dry-bulb temperature and particular relative humidity, wherein selecting said set point is based upon minimizing an amount of energy required to condition the exterior air; and
conditioning the exterior air to the set point.

Abstract
A conditioning system that conditions exterior air for use in a spray booth. The exterior air is conditioned and subsequently used to carry away coating mist, dust, and contaminants from a spray area. The conditioning system heats, cools, humidifies, and dehumidifies the exterior air to a variable set point. The variable set point, while bounded by dry-bulb temperature and relative humidity constraints, is selected based upon cost and/or energy minimization. Additionally, 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, where the localized domain is a geographic area surrounding a manufacturing plant that includes a spray booth.

19. A system for conditioning exterior air for use in a spray booth, comprising:
-
a cooling coil that is adapted to cool the exterior air before the exterior air is communicated to the spray booth; a preheater that is adapted to heat the exterior air before the exterior air is communicated to the spray booth; a humidifier that is adapted to humidify the exterior air before the exterior air is communicated to the spray booth; a reheater that is adapted to heat the exterior air before the exterior air is communicated to the spray booth; and a controller that controls operation of the cooling coil, the preheater, the humidifier, and the reheater to adjust a dry-bulb temperature and a relative humidity of the exterior air to a set point temperature and a set point humidity, respectively, wherein the set point temperature and set point humidity are variable based upon sensed atmospheric conditions and are selected so as to reduce an amount of energy required to condition the exterior air to an acceptable condition for use in the spray booth. - View Dependent Claims (20, 21, 22, 23, 24)
