With the increased popularity of Variable Refrigerant Flow systems, it is easy to often overlook the complex nature and nuances of this unique equipment, which may lead to difficulties after acceptance of the systems and equipment. This presentation reviews the best practices of engineers whose involvement spans the full project scope from design through continuous system operation. Lessons learned from various stages of different projects will be discussed to prepare professionals for future work with these systems.

1. Best Practices and Quality Control Considerations for VRF Projects
Bill Artis, Member, Daikin, New York, NY
While the design and installation of Variable Refrigerant Flow systems is not inherently difficult, there are nuances and details specific to these systems that if overlooked can lead to costly repairs, poor comfort control and improper system operation. This seminar discusses methods of mitigating potential issues before they occur and reviews best practices and considerations for equipment design and selection, contract documents, functional testing and installation quality control.

2. Lessons Learned through Commissioning
Thomas Conn, Horizon Engineering Associates, New York, NY
This seminar reviews lessons learned from projects utilizing VRF systems from the perspective of the commissioning agent. The importance of properly commissioning these sophisticated systems, means of identifying and addressing common oversights found in various project stages and developing realistic plans for incorporating commissioning into a projects scope are discussed. Additionally, examples and lessons learned from projects the speaker has personally been involved with are reviewed to further improve the confidence among industry professionals responsible with commissioning these systems.
