Bangkok RHVAC is held every two years by the Export Promotion Department of the Ministry of Commerce of Thailand. It is the only exhibition in the refrigeration and air conditioning industry in Thailand. In 2011, there were 172 enterprises with 516 stalls, covering an area of 10000 square meters, and 18030 professional visitors from all over the world (trade day: 6200, public day: 12000). The exhibitors are very satisfied with the exhibition effect. Although the exhibition is not large in scale, almost all well-known enterprises participate in it in different ways due to the radiation effect on Southeast Asia and the huge demand of Thailand's local market. The enterprises directly participating in the exhibition include: Daikin, LG, sharp, Fujitsu, Trane, Alfa Laval, Bitzer, Carel, Danfoss, Emerson, Sinko, etc.
