VRF system in Batumi: design, installation and service
We build a VRF system in Batumi to a design: we calculate each room's heat gain, choose outdoor and indoor units, draw the pipe network with factory branch joints, braze under nitrogen, pressure test and evacuate. We fit central control and, where needed, heat recovery for simultaneous heating and cooling. Turnkey VRF from 275 ₾ per m² of area.
from 275 ₾/m²outdoor unit, indoor units, refrigerant pipework and controls, per m² of area. The final price is confirmed once agreed.

VRF system in Batumi: what it is and who needs it
VRF is an air conditioning system in which one or several outdoor units serve many indoor units: wall-mounted, ducted, cassette, floor-standing. Refrigerant runs through a shared pipe network, and each indoor unit takes as much as its room needs. A VRF system in Batumi is installed in villas, aparthotels, boutique hotels and offices, where there are many rooms and no space for a dozen outdoor units on the facade.
VRF, multi-split or ducted units
| System | Number of rooms | What to consider |
|---|---|---|
| Multi-split | 2–5 | Short pipe runs, a limit on the number of units |
| Ducted air conditioners | One zone per system | Each zone needs its own outdoor unit |
| VRF | From 5 to dozens | Long pipe runs, design, central control |
For a small house splits or a multi-split are usually enough, see the air conditioning page.
Design
VRF is never installed without a design. We calculate each room's heat gain, choose the indoor units and an outdoor unit, allowing for the fact that not all rooms run at maximum at once. We draw the pipe network: lengths, the height difference between outdoor and indoor units, the position of branch joints. The outdoor unit usually goes on the roof or a plant balcony, with service access and protection from spray. For hotels and villas where some rooms need heating and others cooling at the same time, we choose a heat recovery system.
Installation
- refrigeration-grade copper pipe, brazed with a nitrogen purge;
- factory branch joints, not home-made tees;
- pressure testing with nitrogen and holding under pressure;
- deep evacuation of the whole system;
- additional refrigerant charge to the actual pipe length;
- a drain from each unit with a fall or a pump.
Installation mistakes in VRF are costly: scale from brazing without nitrogen and moisture in the pipework destroy the compressor, the most expensive part of the system. So we record each stage in a test report.
Control
Each room has its own remote, and a central controller or app shows the whole system: what is on where, any faults, how long each unit has run. For an aparthotel guests' temperature range can be limited and the air conditioner switched off in a room when the key card is removed. VRF integrates with a smart home and building management systems.
Service
Indoor unit filters are cleaned on a schedule, and once a season a service engineer checks the system: pressures, the fault log, the condition of the outdoor unit. By the sea the outdoor unit heat exchanger is rinsed with fresh water. For hotels it is convenient to arrange service under a contract so that the technician comes on schedule rather than after a guest's complaint. The hotels we build are described on the aparthotels page.
How much a VRF system costs
A turnkey VRF system costs from 275 ₾ per m² of served area: outdoor unit, indoor units, refrigerant pipework, controls. A VRF indoor unit installed and connected from 4 020 ₾. For comparison, a ducted air conditioner with ductwork from 8 400 ₾, a multi-split for 2–3 rooms from 8 100 ₾. Laying a pipe run during construction from 480 ₾ per unit, a system service visit from 780 ₾. The final cost is set after the design and an agreed estimate.

Local specifics in Batumi
In Batumi's hotels and villas the air conditioning load peaks in summer: every room is occupied and everyone wants to be cool at once. We size the outdoor unit to cope with real heat and humidity, not just on paper. Rooms on the sunny side get units with spare capacity, those on the shady side standard ones.
VRF outdoor units stand on the roof or a plant balcony, where salty wind and spray reach them. We choose models with a protective heat exchanger coating, mount them on frames with anti-vibration supports and include regular rinsing in the service contract. Noise from large units is taken into account so that it does not disturb neighbours and guests on terraces.

Questions and answers
How much does a VRF system in Batumi cost?
A turnkey VRF system costs from 275 ₾ per m² of served area: outdoor unit, indoor units, pipework and controls. A single indoor unit installed from 4 020 ₾. The price depends on unit types, pipe lengths and controls. The final cost is set after the design and an agreed estimate.
Why is VRF better than several splits?
One outdoor unit instead of a dozen on the facade, long pipe runs, any type of indoor unit and central control. The system holds the temperature in each room more precisely and is more economical at part load. For a house with 3–4 rooms splits are cheaper and simpler.
Can some rooms be heated while others are cooled?
Yes, with a heat recovery VRF. It takes heat from the rooms it cools and gives it to those it heats. This suits hotels and large villas, where the sunny and shady sides live in different modes.
Why can VRF not be installed without a design?
The system has limits on pipe length, height difference and total unit capacity. If they are exceeded, some rooms will not get cooling and the compressor will wear itself out. The design sets pipe diameters, branch joints and the amount of refrigerant.
How is a VRF system maintained?
Indoor unit filters are cleaned on a schedule, and once a season a service engineer checks pressures, the fault log and the outdoor unit. By the sea the heat exchanger is rinsed with fresh water. For hotels a service contract is better, so that checks follow a schedule rather than a guest's complaint at the height of the season.
