Thepatentedsmartvaporinjectiondefrosting technologyofTICA canincrease therefrigerantcirculation flowduringdefrosting, which will shorten the defrosting time,reduce the cold air felt by customers during defrosting,improve the defrosting efficiency, and cut down the power consumption.

Oil Return On Heating Operation Without Shutdown

Traditional units have to be turned off to achieve oil return,while TICA scroll heating series of household VRF units can implement heatingwithoutswitching thedirectionof therefrigerantflow.This seriesadopt themodes of on-demandoil returnand high/low frequency switchover oil return to prevent wild fluctuation of indoor temperature,and provide user with more comfortable experience.
