  • However, the evaporator fan itself generates its own heat through the operation. Recently, electronically communicated (EC) motors have been used for the evaporator fan motor, which reduced its own heat. The problem is that even though the EC motors generate less heat, if the they operate for a long time in uncontrolled manner, the energy consumption cannot be allowable, either. Therefore, it could not be a perfect solution for the problems.
