VRF CONCEALED DUCT AIR CONDITIONING

Xpower VRF is designed to control the flow of refrigerant to each indoor unit via independent PMV control


  • Liquid refrigerant pipe
  • Gas refrigerant pipe
  • Pulse Motor Valve
  • Sensor signal
  • Sensor of temperature difference

Calculation Of The Optimal Refrigerant Flow

For every indoor unit the system detect the difference between the two temperature sensors and regulate the refrigerant flow to reach and maintain the desired level of comfort. This feature is available in cooling mode


Every single blade is designed with a unique profile, a solution that guarantees a smoother air flow without turbulences.


Reduce air resistance of the following wings and made possible for much more quiet sound power level


With the refrigerant control, the CDU is able to select the most efficient heat exchanger size based on the detected capacity load. Increased reliability
