A Variable Refrigerant Flow Heat Pump System
Case Study
& Pointers for Future Designs
by Duane Lewellen
Seattle Public Library, Central Library
1000 4th Avenue (between 4th and 5th Avenues)
Fourth Floor, Room 2
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.
Mr. Lewellen is Vice President of RICE Group, Inc., a Mechanical and Energy Engineering consulting engineering firm located in Lynnwood, Washington. Mr. Lewellen has been with the RICE Group since 1992 and has 30+ years experience in commercial building energy management. Mr. Lewellen is a member of the International Code Council, the Association of Energy Engineers, the Building Commissioning Association, and the US Green Building Council. Mr. Lewellen’s credentials include Certified Energy Manager, Association of Energy Engineers, LEED Accredited Professional, USGBC, and Energy/Mechanical Plans Examiner, International Code Council. Mr. Lewellen is Lead Instructor for the Building Operator Certification program administered by the Northwest Energy Efficiency Council and is a part-time Instructor at Edmonds Community College.
