Low Temp Air

Low temperature primary air systems provide 42°F to 48°F supply air for comfort cooling. The principal advantages of this air delivery option over conventional systems include lower first cost, lower electrical demand and reduced operating costs.

The smaller fans and ductwork diameters required for low temperature air systems not only reduce equipment costs, but also offer the potential for architectural savings, since less floor-to-floor height is needed. And because the fans and pumps used require less horsepower, the system consumes less energy than many traditional types of air delivery.

Low temperature supply air also improves comfort levels by reducing the relative humidity in the occupied space. This reduction in humidity often results in a perceived improvement in indoor air quality. In addition, occupants tend to desire warmer space temperatures which can lead to additional energy savings. Typical room conditions for a low temperature primary air system are 78°F with a relative humidity of 35 to 45 percent.
