ABSTRACT:
An energy management apparatus is disclosed for providing temperature responsive ventilation in an animal enclosure (A). An outside temperature sensor 15 cooperates with a cycle timer 21 to operate an output device such as a ventilation fan (10) for a variable percentage of time during consecutive given time intervals. A controller (12) cooperates with the temperature sensor (15) and the cycle timer (21) to automatically vary the percentage of fan (10) operation time during each given time interval in response to temperature changes in the outside air whereby constant minimum ventilation efficiency is maintained within enclosure (A). An indoor temperature sensor (16) can be optionally provided to override the outdoor sensor (15) to ensure that the temperature within the enclosure (A) remains within desired limits.
