Multi-split systems are air conditioners with a single outdoor unit connected to two or more indoor units. The most common variant is the dual-split system (one outdoor unit combined with two indoor units), but there are also triple-split (1:3), quadruple-split (1:4), and quintuple-split (1:5) models.

This product line thus allows for a reduction in the space required for installation outside the room to be air-conditioned, without compromising comfort indoors.
