Variable Refrigerant Flow System Design

Summarize the different types of variable refrigerant flow vrf systems available.

Variable refrigerant flow system design.

With a higher efficiency and increased controllability the vrf system can help achieve a sustainable design. Variable refrigerant flow vrf also known as variable refrigerant volume vrv is an hvac technology that was invented in japan in the 1980s. 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. 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.

The specific design of a vrf system varies based on application. The simplest explanation of vrf is to describe it as a large scale ductless hvac system that can perform at a high capacity. Variable refrigerant volume vrv system so other manufacturers use the term vrf variable refrigerant flow. 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.

Vrf systems are characterized by their superior energy efficiency and their flexible output according to load. Plus york vrf system integration with building automation systems is best in class. Explain the pros and cons of using vrf systems in a commercial building application. Regardless of the capacity energy efficiency functionality or performance monitoring.

Complexity is the name of the game when describing the technical nature of how variable refrigerant flow technology works. Unfortunately the design of vrf systems is more complicated and. This fully integrated high performing hvac system solution is designed to deliver customized comfort throughout any commercial space. Identify the codes and standards that dictate the design and use of vrf systems.

Trane has paired applications knowledge and expertise with its extensive equipment and controls offerings to provide variable refrigerant flow vrf systems solutions. Our full line of vrf system technology offers design flexibility and optimal performance. All other companies use vrf variable refrigerant flow 2 for their similar hvac systems. Variable refrigerant flow vrf systems are now becoming increasingly utilized across north america.

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 flow systems deliver optimal comfort and are among the most efficient hvac systems. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. In essence both are same.
