Track: Standards, Guidelines and Codes
Sponsor: 8.7 Variable Refrigerant Flow (VRF)
Chair: Madison Schultz, P.E., Member, Guernsey Engineers/Architects/Consultants, Oklahoma City, OK

Standards, guidelines and codes committees are regularly releasing new revisions. Some of these have specific provisions for VRF systems and some leave things…open to interpretation. This session covers the need-to-knows on how the requirements of IECC 2015, ASHRAE 90.1-2016 and ASHRAE 15/34-2016 apply to the design of VRF systems. The presentations also cover ventilation options for VRF for compliance with ASHRAE 62.1, and specific requirements to comply with the City of Chicago mechanical code.

1. Ammonia/Carbon Dioxide Secondary Systems
Arthur Sutherland, Member, Accent Refrigeration Systems, Victoria, BC, Canada
Over 20 recreational ice facilities in Europe and Asia have adopted indirect refrigeration systems utilizing ammonia as the primary refrigerant and Carbon Dioxide (CO2) as the secondary coolant. Ammonia, well known for its high efficiency, when combined with CO2 as a secondary coolant creates a Hybrid system that enjoys tremendous efficiencies on both sides of the indirect system. Learn why the University of Alaska’s, Wells Fargo Arena was the ideal candidate for an energy saving Ammonia / CO2 system and how they reclaimed to 100% of their available low grade heat during the process.

2. Designing VRF Systems for Compliance with ASHRAE Standard 15 and ASHRAE Standard 34-2016
Keith Hammelman, P.E., Member, Cannon Design, Chicago, IL
This presentation discusses the important compliance requirements for ASHRAE 15/34-2016 as it relates to VRF systems.

3. Ventilation Options When Designing VRF Systems
Bill Artis, Member, Daikin, New York, NY
