High-efficiency Variable Refrigerant Volume / Flow climate control delivering independent multi-zone heating and cooling for modern commercial offices, hotels, and luxury residences.
Precise Temperature Control
Up to 40% Energy Savings
VRV/VRF air-conditioning systems provide flexible and energy-efficient climate control for multiple zones. Sustainergic Tech designs customized VRV/VRF solutions that offer precise temperature control, reduced energy consumption, quiet operation, and easy scalability for modern buildings.
Continuously adjusting refrigerant flow rates to match exact instantaneous cooling and heating demands per room.
Transferring waste heat from cooled zones (e.g. server rooms) to heat other zones or hot water simultaneously.
Combining 4-way ceiling cassettes, slim ducted units, wall splits, and floor consoles on a single outdoor loop.
Integrating BACnet / Modbus BMS gateways, tenant power proportioning (PPD) billing, and remote app management.
Delivers either cooling or heating to all connected indoor units simultaneously. Ideal for buildings with uniform seasonal climate requirements such as residential apartments and retail stores.
Allows simultaneous cooling in sunny/perimeter zones and heating in shaded/interior zones. Recycles heat within the building envelope, achieving industry-leading integrated COP ratings.
Uses water or geothermal ground loops for heat exchange instead of air, while integrating an HTS Panel with VRF systems to achieve a COP of up to 6. The compact indoor installation also eliminates outdoor condenser clutter, making it ideal for high-rise buildings.
Connects VRF inverter outdoor units to central Air Handling Units (AHUs) or DOAS fresh air systems, providing 100% pre-conditioned outdoor air with inverter energy efficiency.
Variable speed DC inverter scroll compressors adjust motor speeds continuously, eliminating the high current spikes and energy waste of traditional ON/OFF compressors.
Every office, hotel room, or residential suite has its own independent digital thermostat, enabling personalized temperature setpoints without affecting adjacent zones.
Modular outdoor units fit into standard service elevators and small balcony spaces, reducing structural loads and eliminating massive roof duct shafts.
Aerodynamically engineered indoor fans and electronic expansion valves (EEVs) deliver ultra-quiet sound levels, ensuring serene working and sleeping environments.
Calculating room-by-room sensible and latent heat loads, diversity factors, and selecting appropriate indoor unit types (cassette/ducted).
Routing copper refrigerant lines, sizing Y-joints, calculating equivalent pipe lengths, vertical oil drops, and branch selectors using VRF selection software.
Wiring non-polar 2-core communication cables, central touch screen controllers, tenant kWh power meters (PPD), and BMS gateways.
Performing 24-hour 4.15 MPa nitrogen holding pressure tests, triple vacuum evacuation down to 500 microns, and precise R-410A / R-32 auto-charging.
Hydronic ceiling and floor thermal radiation delivering uniform temperature without draft.
Ultra-thin electric thermal heating cables for luxury residential and commercial comfort.
Certified sustainable building designs, net-zero consulting, and energy optimization.
