York Digital Scroll [YDS]
Why Why DaikinDaikin promotes inverter technology promotes inverter technology
1982 : Daikin started Launching of VRV first in the world AND have used inverter technology since early days and have used inverter technology since early days and has gained much trust. has gained much trust.
2009 : Daikin still use Inverter for new model
