We can connect up to 60 indoor units of different sizes and capacity with a single outdoor unit .Two types of compressor are used in VRF units

  1. Digital scroll compressor
  2. Inverter Scroll compressor

Refrigerant used in these compressor are 410A and 407C.We can connect the indoor unit with the outdoor unit by piping up to 150 meter. For Split AC this is 15 meter. Up to 30% to 40 % power saving can achieved by using this type of system rather than split ac system in the building where a lot of indoor units are required.
