For cooling load calculations, while taking into consideration Electric Motor Load, ASHRAE Handbook Chapter 30.7 for Non residential cooling and heating load calculations, gives maximum load while driven equipment is in the conditioned space. e.g for for 7.5hp motor it gives in btu/hr 1. Motor in driven equipment in 22700, 2. motor out driven equipment in 19100,3. Motor in driven equipment out 3640. What I fail to understand, does driven equipment generate more heat that motor itself, which is consuming energy, producing IR losses (Heat Losses). If motor only is in conditioned space, according to book, it generates least amount of heat. Please let me know where I am wrong. I know hand book can not be wrong.
Thanks and best regards
