• ### Heat Gain from Electric Motors HVAC/R engineering EngTips

Jun 17, 2003 · There is no useful conversion of energy between the air in the room and the motor. You only need to determine what the normal motor surface temperature is for full load amps and then calculate the heat released to the atmosphere via radiation and conduction. It will not be anything near the complete energy conversion of 2545 BTU/Hp for the motor.
