Abstract
Abstract An environmental control system controlling an air cooling means, a heat reclaiming means, fresh air supply, auxiliary heaters when necessary, and temperature and humidity sensors, all of which are coordinated by an environmental control panel. The panel would in addition to providing temperature regulation also control the humidity by overcooling the air by the A.C. reducing humidity and then using the reclaimed heat and/or auxiliary heat to heat the air to a desired level and would utilize individual-temperature calibrated-sensors to achieve exact control of steps signaled from control panel to heating and cooling equipment.
