Space conditioning indoor air typically involves more than just cooling. Occupant comfort requires moisture removal and air exchange with the outdoor air for improved indoor air quality (IAQ). Each of these aspects requires additional air conditioning capacity, resulting in drained condensate water and exhausted indoor air. What if there was a way to reclaim this capacity to improve the efficiency of the mechanical cooling system?
That is the basic idea behind technology from Global Energy Group (GEG) of Odessa, FL. The company calls this patented concept EER+, and it is incorporated in the Inventor Series 1400 packaged unit, to be introduced in September, 2002. The Inventor Series 1400 carries an EER rating of 13.5; and, according to the company, these packaged units have the highest EER ratings as certified by ARI 340/360.
