VRT mode is efficiency focused while Basic mode is capacity focused.
Selecting VRT enables operation to be optimised for either energy efficiency or rapid cooling.
Ambient VRV IV S
The Daikin Swing Compressor
›› Daikin VRV IV S-series is built with the highly reliable Daikin swing compressor
›› Daikin’s swing compressor technology integrates all the moving parts into one component
›› The integration minimizes abrasion between moving parts and refrigerant leakage through gaps from
high to low pressure zones
›› Daikin’s swing compressors deliver higher compressor efficiencies than a standard rotary compressor
