Multi-Split Air Conditioners

About

Cool and heat several rooms from a single outdoor unit with our range of Multi-Split Air Conditioners , built for homes and workplaces that need more than one zone of climate control without cluttering an exterior wall with multiple condensers. Please note: We are legally required to verify your F-Gas certification before supplying restricted refrigerants. Orders without valid certification will not be processed. Form can be found via F-Gas certification form link What is a multi-split system? A multi-split system connects one outdoor condensing unit to two or more indoor units, typically wall-mounted, though cassette, ducted and console indoor units can often be mixed on the same outdoor unit depending on manufacturer compatibility. Each indoor unit is controlled independently, so a bedroom can run at a different temperature and schedule to a living room or office, all from the same outdoor box. This differs from a single-split system , which pairs one indoor unit with one dedicated outdoor unit and suits a single room. It also differs from larger VRF/VRV systems , which serve many zones across commercial buildings and require a more complex design process than domestic multi-split. If you're cooling or heating just one room, our Split Air Conditioners collection covers single-split units. Most domestic multi-split systems are reverse-cycle air-to-air heat pumps, so they provide both cooling in summer and efficient supplementary heating in winter, alongside dehumidification for damp shoulder seasons. How multi-split systems are sized Getting the sizing right on a multi-split system is less straightforward than a single split, because one outdoor unit has to support several indoor units running simultaneously. Indoor units are sized to the room , the same way as single-split — floor area, ceiling height, glazing and orientation, and occupancy all matter, with south- and west-facing rooms typically needing more capacity. The outdoor unit is sized using diversity , no
