Vrv Vrf Air Conditioning Systems

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.

Vrv vrf air conditioning systems.

All other companies use vrf variable refrigerant flow 2 for their similar hvac systems. Vrf refers to the same basic technology used in those systems manufactured by other companies fujitsu for one makes some great variable refrigerant flow systems. This company was the industry leader at the time so they trademarked the vrv name to describe the system. In reality these two systems use the same exact technology.

This sophisticated new vrf hvac technology is capable of providing not only cooling but also heat and even both simultaneously to different areas within the space. The term variable refrigerant flow or vrf refers to the system s ability to control the amount of refrigerant flowing to each of these small air handlers. Vrf systems unlike conventional chiller based systems allow for varying degrees of cooling in only certain areas reducing energy consumption. To start off vrv and vrf air conditioning systems are technically the same.

Like ductless minisplits vrfs use refrigerant as the cooling and heating medium. The daikin vrv system is a multi split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building. Vrv multi split type air conditioners. When daikin launched the vrv air conditioning system in 1982 it introduced the world s first use of variable refrigerant volume control.

This refrigerant is conditioned by a single or multiple condensing units and is circulated within the building to multiple indoor units. Variable refrigerant flow also known as variable refrigerant volume is an hvac technology invented by daikin industries ltd. Eventually vrf is the more common term for these types of systems and this is the term that will be used for the rest of the article. The vrv and vrf mitsubishi aircon system is equivalent to the commercial grade air conditioning system.

However daikin has copyrighted the term vrv while other aircon brands use vrf to refer to their own hvac systems. Also referred to as a vrf system variable refrigerant flow is a technology that circulates only the minimum amount of refrigerant needed during a single heating or cooling period. Originally created in the early 1980s vrv systems were designed by daikin. Some people mistakenly believe that vrv and vrf air conditioning systems are two independent hvac systems.

This is able to meet your air conditioning needs for various projects from offices to commercial building. Vrv is term copyrighted by daikin one of the true industry leaders in hvac equipment and technology. Daikin s vrv variable refrigerant volume systems first emerged in the 1980s pioneering one of the first hvac systems. Vrv vrf systems can be as simple or complex as you would like them to be.
