Air pollution in metal fabricating shops and other small industrial customers' shops, is a problem. This pollution may be present as non-toxic fumes or mist. Sources of these fumes and mist may be welding processes or metal machining. Unions and various government agencies may exert pressures to remove? this air pollution.

The historical method that has been used to remove these pollutants has been to exhaust air from the shop. The amount of exhaust air is normally very large so that mist and fumes can be diluted quickly. As the sources or amounts of air pollution increase so will the amounts of exhaust air. In many shops this exhaust air is not only heated but cooled also. With increasing energy costs, this method of air pollution control may not be the best solution.

As an alternate solution, the concept of cleaning the heated and cooled air should be investigated, This cleaning of in-plant air will be done with electrostatic air cleaners suspended in space. The method of this investigation will be to run two energy studies on a typical shop building. The base case will be the conventional ventilating system where clean heated and cooled make-up air is supplied to the building and polluted air exhausted. The alternate case will be to reduce the amount of outside air by using electrostatic air cleaners. The annual amounts of energy (heating and cooling) can then be compared for these two cases.

Once the energy input to the buildings is known, it can be priced to give annual operating costs. Also there will be a reduction in installed heating and cooling equipment capacity.
