This presentation covers the very basics of VRF – What is it? Why use it? When to use it? And maybe most importantly, when NOT to use it. The presentation will hit key highlights from VRF Chapter of the ASHRAE Handbook. In addition, this presentation cover the most important design considerations for VRF systems, including some best practices and lessons learned from real-life applications.

A combined VRF and DOAS building system offers many advantages, such as energy efficiency, enhanced occupant comfort, and reduced mechanical system space requirements. To realize these benefits and meet the requirements of the space (sensible temperature, humidity ratio, and ventilation requirements), the designer must pay close attention to system design and application. This presentation will cover basic system design concepts for a VRF + DOAS system, advantages and disadvantages of various system designs, and key considerations for meeting code and space requirements.
