Free Webinar: Variable Refrigerant Flow/Volume (VRF/VRV) for Commercial Buildings, June 24, 9-11 am, PT
Event Description
Variable Refrigerant Flow/Volume (VRF/VRV) are building heating and cooling air conditioning systems that utilize refrigerant as the medium of heat transfer and are currently the standard for residential and commercial systems in Asia and Europe. They continue to gain market share in the United States as the reliable, modular, and highly efficient alternative to traditional residential fixed-speed compressor systems, commercial air-to-air and central plant HVAC systems. Attendees will be provided with an overview of VRF heat pumps and heat recovery systems, including a descriptive overview of indoor fan coils and outdoor condensers, specialty options, system optimization, and basic design considerations for upcoming A2L-R32 refrigerants for applications in the commercial vertical market. Attendees will be able to understand applications for VRF systems in the commercial market as well as recognize opportunities for optimized design of VRF systems, equipment, and specialty options.
The objective of this course is for participants will be able to:
- Demonstrate how to recognize purpose, equipment, and features of VRF/VRF systems for basic application, selection, and design of VRF heat recovery and heat pump systems, to include:
Heat pump vs. heat recovery: applications of these systems in the commercial market
Outdoor units: features and typical applications
Indoor unit: features and typical applications
Branch selector boxes: single-port vs. multi-port and optimizing heat recovery design
System accessories: options available to enhance the system application
A2L refrigerant: considerations for the design of VRF/VRV R32 systems
Design optimization: considerations for the proper design of heat pumps and heat recovery systems
