VRF technology: Cooling, heating, or both?
2 and 3-pipe systems
When it comes to VRF multi-room systems, you can choose between 2-pipe and 3-pipe systems for cooling and/or heating.
2-pipe system
This system can cool or heat according to the season and the users' requirements. It creates the ideal balance of temperature and humidity for low operating costs. The many possible combinations of indoor units as well as the uncomplicated pipework and wiring offer high levels of flexibility.
3-pipe system
This system allows simultaneous and independent cooling and heating. This technology is particularly efficient in buildings with extreme variations in the thermal load depending on the orientation of the building, or spaces that constantly produce waste heat. The thermal energy absorbed from one area of the building can be made available for heating other rooms with virtually no heat loss. This guarantees maximum cost-effectiveness.
1,200 m pipe length
A piping length of up to 1,200 m allows flexible design and installation.
110 m height difference
The height difference between outdoor unit and farthest indoor unit can be up to 110 m. This is equivalent to the height of a 30-story building.
Compact design
Compact dimensions ensure a small footprint.
Flexible refrigeration circuits
Several refrigeration circuits can be combined to form one large system, so that they can be controlled centrally.
