The design of the air conditioning systems for an industrial electrical equipment room is normally performed in parallel with the facility electrical system design. This means that the cooling equipment is sized based on estimated heat rejection values. Because the heat from the electrical equipment is often a significant percentage of the total cooling load, accuracy is important to a successful air conditioning system design. In a room with a significant source of equipment generated heat, nearly all the heat has to be removed. This is because, for a well-insulated envelope, the indoor temperature must become dramatically higher than the outdoor temperature for heat transfer from the inside to the outside.

The objective of this research project is to obtain a body of relevant and accurate data on the heat gain from electrical and control equipment for application of air conditioning and ventilating systems.
