Daikin 3-pipe technology needs less energy to
recover heat, meaning significantly higher efficiency Condensing 55 °C
during heat recovery mode. Our system can recover
heat at a low condensing temperature because it has Condensing 45 °C SKY AIR
dedicated gas, liquid and discharge pipes.

In a 2-pipe system, gas and liquid travel as a mixture Power input Daikin
so the condensing temperature needs to be higher in
order to separate the mixed gas and liquid refriger- Power input 2-pipe system
ant. The higher condensing temperature means more VRV
energy is used to recover heat resulting in lower Enthalpy
efficiency.
