Summary

The input power of process equipment driven by electric motor is the heat diffused by the electrical equipment and the average input power of the electrical equipment in a work shift is equivalent to the heat diffused by the equipment. The heat diffused by the equipment can be determined after obtaining by calculation the input power or average input power of the equipment. Thus, the cooling load resulting from the heat can be determined. The method that the cooling load resulting from the equipment is determined by means of calculating electric load is clear in concept and correct in result. The load obtained by the method is much smaller than that by the conventional method. Hence, the capacity of an air-conditioning system and distribution transformer can be decreased. The initial investment and the operation cost can be saved.
