A Variable Refrigerant Flow Heat Pump System - Case Study, and Pointers for Future Designs

Where	5th floor conference room 901 5th Avenue Seattle, WA 98124

In Chehalis, Washington, split-system constant-volume air-to-air heat-pumps were replaced with VRF ductless, heat recovery heat pumps in a medium sized office building. 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 may want to follow to avoid any common pitfalls in VRF retrofits.
