Mini VRF units are slimmer and more compact, resulting in significant savings in installation space. In some large residential spaces or some light commercial space, such as villa, restaurant, usually it need more than one indoor unit, so outside the building are also full of outdoor units. Now Carrier can provide an effective solution-Carrier MINI VRF DC Inverter system. Since now the beauty of the building will be back.

MINI VRF DC INVERTER High Reliability
Smooth Control During Start-UpBy using inverter-driven compressors, Carrier is able to significantly reduce the electrical and mechanical stresses that are placed on fixed-speed compressors during start-up. Current absorption on an inverter-driven compressor is smoothed out at start-up thus reducing the wear on the electrical and mechanical components and increasing reliability.

Indoor Unit Quantity Monitoring
The quantity of indoor units should be exactly set on the outdoor main board, once some indoor units miscommunication with outdoor units during system running, the outdoor units will stop and display the fault code “H7”. This can prevent compressor from liquid hammer caused by dropped indoor units with EXV unclosed.

Auto-Restart Function
Forced Cooling
Even if an extended power failure occurs, the Mini VRF system automatically restarts with the same settings.
A power failure will not cause any settings to be lost, thus eliminating the need for re-programming.
Forced cooling button makes outdoor unit run in cooling mode at any condition, so it is very easy for installer to charge refrigerant to the system when it need to be done.
The self-diagnosis function detects malfunctions in major locations in the system and displays the type of malfunction and location. This allows service and maintenance to be performed more efficiently.

More convenient piping connector
Easier and safer installation thanks to a branch box that simplifies piping work and the adoption of screw connection.
Both left and right pipe flare connecting from outdoor unit to branch box is reserved, simplified the field installation.
Two sets of pipe size converter are packed with branch box to transfer the pipe size from Φ6.35 to Φ9.53 and from Φ12.7 to 15.9.
Low Sound The branch pipe is linear expansion design which regulates flow of refrigerant and reduces the noise. By locating the branch box in the ceiling or outside ,noise generated by the branch can be kept clear of living spaces, thus maintaining the noise to a minimum.
Brazing-Free Quick Installation All the piping leading to and from the branch box is connected using screw joints, which are easy to use and enable piping installation to be completed quickly.
Indoor Units Installation The branch box can be installed in the ceiling rather than outside. Furthermore , servicing can be complete easily through access to inner components such as the circuit board by simply removing the side and bottom covers.
Universal Indoor Units The same indoor units as R410A DC inverter MINI VRF system.
