This will induce fresh new, outside air to be provided into the program. When the skin air is cooler when compared to the demanded great air, this will permit the demand from customers to get achieved without having utilizing the mechanical source of cooling (commonly chilled h2o or even a direct growth "DX" unit), As a result conserving energy.
