Two-pipe systems
All indoor units operate in the same mode—cooling or heating. Suitable for most standard buildings.
Planas multi-zone air conditioning
VRF systems for buildings with individually controlled climate in every zone
Multi-zone VRF systems allow one or more outdoor units to serve multiple indoor units in different rooms. Each user can set the temperature independently, while inverter compressors smoothly adjust their capacity to match the current load. This is a flexible, energy-efficient solution for offices, hotels, shopping centers, and residential complexes.
- Flexible configurationFrom compact mini VRF systems to modular systems for large buildings.
- Personalized comfortA comfortable temperature is maintained in every room.
- Energy efficiencyInverter control helps save electricity.
What is a VRF system and how does it work?
VRF is a multi-zone air-conditioning system with variable refrigerant flow. One or more outdoor units are connected to indoor units by copper pipes, while the control system regulates the amount of refrigerant supplied to each zone according to its current needs. Unlike conventional split systems, VRF can serve many rooms simultaneously. Inverter compressors allow the equipment to adjust smoothly to the load, maintaining a stable indoor climate while reducing electricity consumption.
Design and operating principle
What a VRF system consists of
The main components are outdoor units with inverter compressors, various types of indoor units, electronic expansion valves, and a control system. Refrigerant circulates through a closed loop: the compressor compresses it, then it flows to the indoor units, where heat is exchanged with the air, before returning to the outdoor unit. In three-pipe systems with heat recovery, the system can cool some zones and heat others at the same time.
Where VRF systems are used
VRF systems are suitable for buildings with many rooms and varying indoor climate requirements.

System options
How to choose a VRF system configuration
Different types of multi-zone systems are available to suit your building and required operating modes.
Three-pipe systems with heat recovery
Allow some zones to be cooled while others are heated at the same time by redistributing heat.
Mini VRF
A compact solution for smaller buildings with a limited number of indoor units.
Modular VRF systems
A scalable configuration with multiple outdoor units for large buildings.
How a VRF system works
The system operates in a closed loop, automatically regulating refrigerant flow to each indoor unit.
- 01Refrigerant compression
The compressor in the outdoor unit increases the refrigerant pressure and temperature.
- 02Distribution to zones
Refrigerant is directed to the indoor units in the required state.
- 03Heat exchange with the air
Indoor units transfer heat to or remove heat from the room air.
- 04Automatic adjustment
Electronic valves precisely adjust refrigerant flow for each zone.
- 05Return to the outdoor unit
The refrigerant returns to the outdoor unit, and the cycle repeats.
