A Variable Refrigerant Flow Heat Pump System

Case Study
& Pointers for Future Designs

by Duane Lewellen

January 17, 2012
Noon to 1:00

901 5th Avenue, Seattle
5th Floor Conference Room

As part of a major renovation of a medium sized office building in Chehalis, Washington, split-system constant-volume air-to-air heat-pumps were replaced with VRF ductless, heat recovery heat pumps.  The existing air distribution system became a dedicated outside air system with heat recovery. 

Energy performance comparisons are now available from computer models of the existing and proposed systems, as well as submetering performed as part of an EPRI national study.  Five months of data are currently available.   This talk will offer the audience specific insights derived from the Chehalis project, as well as general guidelines designers will want to follow to avoid any common pitfalls in VRF retrofits.
