Variable Refrigerant Flow System Design
Identify the codes and standards that dictate the design and use of vrf systems.
Variable refrigerant flow system design. Variable refrigerant flow vrf also known as variable refrigerant volume vrv is an hvac technology invented by daikin industries ltd. Our full line of vrf system technology offers design flexibility and optimal performance. This course provides an overview of variable refrigerant flow vrf technology including equipment and system types heating cooling operation heat recovery and the benefits of vrf systems. Variable refrigerant volume vrv system so other manufacturers use the term vrf variable refrigerant flow.
Variable refrigerant flow vrf systems are now becoming increasingly utilized across north america. Also described is the vrf design process including load profile analysis unit sizing ventilation air strategy refrigerant piping design and system. Variable refrigerant flow vrf also known as variable refrigerant volume vrv is an hvac technology that was invented in japan in the 1980s. The simplest explanation of vrf is to describe it as a large scale ductless hvac system that can perform at a high capacity.
All other companies use vrf variable refrigerant flow 2 for their similar hvac systems. Regardless of the capacity energy efficiency functionality or performance monitoring. This refrigerant is conditioned by a single or multiple condensing units which may be outdoors or indoors water or air cooled and is circulated within the. Complexity is the name of the game when describing the technical nature of how variable refrigerant flow technology works.
Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. This fully integrated high performing hvac system solution is designed to deliver customized comfort throughout any commercial space. This course provides nonmanufacturer specific concepts of the unique operational characteristics of vrf systems and how to apply vrf systems to a wide range of building types. The specific design of a vrf system varies based on application.
Variable refrigerant flow systems. Explain the pros and cons of using vrf systems in a commercial building application. Summarize the different types of variable refrigerant flow vrf systems available. Trane has paired applications knowledge and expertise with its extensive equipment and controls offerings to provide variable refrigerant flow vrf systems solutions.
Vrf systems are characterized by their superior energy efficiency and their flexible output according to load. Eventually vrf is the more common term for these types of systems and this is the term that will be. With a higher efficiency and increased controllability the vrf system can help achieve a sustainable design. In essence both are same.
As a technology leader in the hvac industry daikin had registered the vrv term which stands for variable refrigerant volume 1 as an official trademark.
