Variable Refrigerant Flow System Design

Also described is the vrf design process including load profile analysis unit sizing ventilation air strategy refrigerant piping design and system.

Variable refrigerant flow system design. 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. Variable refrigerant flow vrf systems are now becoming increasingly utilized across north america. Variable refrigerant flow vrf also known as variable refrigerant volume vrv is an hvac technology invented by daikin industries ltd. Variable refrigerant flow systems.

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. Trane has paired applications knowledge and expertise with its extensive equipment and controls offerings to provide variable refrigerant flow vrf systems solutions. Eventually vrf is the more common term for these types of systems and this is the term that will be. Identify the codes and standards that dictate the design and use of vrf systems.

In essence both are same. Plus york vrf system integration with building automation systems is best in class. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. 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.

Variable refrigerant flow systems deliver optimal comfort and are among the most efficient hvac systems. Regardless of the capacity energy efficiency functionality or performance monitoring. Variable refrigerant volume vrv system so other manufacturers use the term vrf variable refrigerant flow. All other companies use vrf variable refrigerant flow 2 for their similar hvac systems.

Explain the pros and cons of using vrf systems in a commercial building application. 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. Our full line of vrf system technology offers design flexibility and optimal performance.

The simplest explanation of vrf is to describe it as a large scale ductless hvac system that can perform at a high capacity. Summarize the different types of variable refrigerant flow vrf systems available. 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.

With a higher efficiency and increased controllability the vrf system can help achieve a sustainable design.
