New Carrier White Paper Highlights Importance of Fan Selection in Commercial Applications

The indoor fan serves as a vital component in every forced-air, space-conditioning system. Not only is the fan the principal means for delivering conditioned air to a space, it has a direct impact on system efficiency, perceived comfort levels and air quality within that space. In Carrier’s latest white paper, “Application of Fans in Commercial HVAC Equipment,” readers can explore different types of fans and their applications in air handlers and rooftop units. Carrier, the world’s leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE: UTX).

The paper, available free at, examines how equipment designers determine what type of fan arrangement will be optimal in a specific application by understanding the operating characteristics and application strengths of different types of fans and drives. The paper also describes various types of fans used in HVAC applications and how factors such as sound and cost analysis can affect the selection of a particular fan in a commercial product.

“The proper selection of the fan arrangement is critical to the efficiency of a commercial HVAC system,” said Greg Alcorn, vice president, commercial sales and marketing, Carrier. “This white paper examines different fan options available in the commercial space, along with the factors that go into the evaluation of which are applicable in a given situation.

“Carrier white papers build on our legacy of innovation and training by examining the issues that are shaping the industry. This white paper is a prime example of how Carrier leads the way in education and training as it provides a comprehensive look into the selection process Carrier engineers use when designing commercial solutions,” Alcorn said.
