Time: 12:00 noon - 1:30 pm

Location: Barrio Brewery

Active and Passive Beams
Active beam systems are gaining popularity in the North American market. When used correctly, they can reduce HVAC system energy consumption for cooling and heating when compared to all air systems. Active and passive beams are especially effective in renovation projects where cooling capacity of the system needs to be increased without increasing duct sizes. This presentation will describe beam operation principles, and focus on special considerations during HVAC system design and commissioning. Application cases for beams operating in constant and variable air volume systems will be described. This presentation will also describe efficient ways of integrating active beams with Dedicated Outdoor Air Systems. Specifics and limitations of using beams in heating mode will also be discussed.
