Kanaoka, the Place Where VRV Comes from - A visit to Daikin Kanaoka Factory in Sakai City

摘要

In 1982, Daikin launched its first VRV (Variable Refrigerant Volume) system, Daikin's registered trademark for VRF building type multi air conditioning systems. Although only 174 systems were sold in that year, VRV has since become a star product, with more than one million systems now having been sold in over 70 countries around the world. During its 26-year history, VRV's range of application has been expanded significantly from its initial target of small- and medium-sized office buildings. The system can now be found in large-size office buildings of more than 100,000 m2 as well as 60-story skyscrapers. Recently, there have also been an increasing number of installations in luxury residences, mainly in high-rise condominiums. The growing international concern regarding environmental issues that started in the early 1990s and the sudden jumps in energy costs in the last few years are steadily increasing needs for greater energy saving. Because VRV's No.1 feature is energy saving, it has become the standard name used for this type of system in the international market. In order to learn more behind the VRV system, JARN visited the Daikin Kanaoka Factory at the Sakai Plant, the home of VRV, on December 12, 2008.
