DEVap air conditioning solves the most vexing problem for air condition engineers by efficiently separating latent (dehumidification) from sensible (temperature) loads. Unlike a conventional system that must cool to dehumidify, DEVap air conditioning can do one or the other, or both. In other words, dehumidify without cooling and cool without dehumidifying, allowing you to set individual thresholds for latent and sensible loads without compromising efficiency for comfort. In some climates, such as Seattle, building owners could benefit from combining dehumidification with heating, explains Jason Woods, a lead researcher on DEVap air conditioning with NREL.
