This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The name VRV * derives from this technology that we call “variable refrigerant volume.”

Variable Refrigerant Volume What Do VRF and VRV Stand For? VRV stands for "Variable Refrigerant Volume," while VRF stands for "Variable Refrigerant Flow".

In 1958, Daikin introduced Japan's first window type air conditioner with rotary compressor was Daikin. In 1982, Daikin invented the world's first revolutionary VRV® system. This breakthrough made its way through the world over the years to become the world's most efficient DX system.

A typical system consists of an outdoor unit (comprising one or multiple compressors), several indoor units (often mistakenly called "fan coils"), refrigerant piping running from the outdoor to the indoors, using Refnet Joints (copper distributors in pipes) and communication wiring.

Three Types of VRV Systems There are three different types of VRV systems: cooling-only, heat pump, and heat recovery. Cooling-only systems provide only cooling and dehumidification. Heat pump systems are the most popular type. They provide both heating and cooling.

VRV is short for “Variable Refrigerant Volume,” and VRF is “Variable Refrigerant Flow.” And they both refer to how an HVAC system uses refrigerant. In 1980, VRV was originally designed and copyrighted by Daikin, the industry leader at that time.

For years, Crunchyroll has run VRV as an alternative to its main platform for fans who want more content outside of just anime. It has hosted shows from some big names in nerdy entertainment spheres, like Geek & Sundry, Cartoon Hangover, Rooster Teeth, Nerdist, and Shudder.

An AHU designed for outdoor use, typically on roofs, is also known as a rooftop unit (RTU) along with VRV System. Variable refrigerant Volume (VRV) systems vary the flow of refrigerant to AHU units. Variable refrigerant Volume (VRV) systems vary the flow of refrigerant to AHU units based on demand.

What is the difference between air cooled chiller and water cooled chiller? Chillers cool the water then pump the cooled water through the building to the fan coils. A VRV/VRF system cools the refrigerant then pumps that through the building to all the air handlers.

Structure of VRV or VRF System Basically, it consists of a large outdoor unit (comprising one or multiple compressors) which is connected to several indoor units with refrigerant piping that passes air from outdoor to indoor units utilizing the refnet joints and communication wiring.

Ellation History. Ellation, owners of Crunchyroll, formally announced the launch of VRV on June 14, 2016. Its initial partners included Rooster Teeth, Seeso, Nerdist, Geek & Sundry, and Frederator's Cartoon Hangover.
