Abstract:
An air conditioning system of multiple air conditioners for achieving a desired temperature and maintaining it within a specified variation, in an air stream passing through a confined painting space, each of said multiple air conditioners supportive of a cooling coil set placed within the air stream, and comprising:a heater; a first of the multiple air conditioners, responsive to a first sensor that is situated in the air stream proximate the air stream's introduction to a ceiling plenum that services the booth, said first sensor adapted to sense a first temperature; another of the multiple air conditioners, responsive to another sensor that is situated in the air stream distal the first sensor and adapted to sense a second temperature, thereby establishing a temperature differential with respect to the first temperature; and at least one control means for electrically switching and sequencing the heater and the multiple air conditioners and for assuring that one or more air conditioners runs constantly throughout a demand cooling phase, thereby attaining said desired temperature and concomitantly using the temperature differential to effect said specified variation in booth temperature.
