A Peer Reviewer Said It. The Fluid Flow Proves It.

An independent review concluded the Diamond-Shaped Actuator has real potential to help mitigate climate change. This video shows exactly why — walking through the fluid flow at each stage of operation, so you can see how it works, not just take someone’s word for it.

Mixed air in HVAC systems is the blend of return air from the building and outdoor air. Conventional control strategies waste significant energy by continuously maintaining the mixed air at a temperature cold enough to satisfy the building’s maximum cooling requirement. During most operating conditions this results in unnecessary overcooling, forcing the heating system to reheat the air to maintain comfort—a costly cycle of simultaneous cooling and heating.
