We are often asked; "Can more than one indoor unit be connected to just the one outdoor unit?"
In a word - YES! This type of system is called a multi-split system and differs slightly from a split system, which is a system which has one outdoor unit connected to one indoor unit.
A multi-split system is a design of a/c system that shares similarities with a split system but allows for multiple indoor units to be connected to a single outdoor unit.
In a multi-split system, each indoor unit serves a separate zone or room within the building, providing individualized climate control. These indoor units can vary in type and capacity, such as wall-mounted units, ceiling cassettes, or ducted units, depending on the specific requirements of each space.
The outdoor unit of a multi-split system contains the compressor, condenser coil, and fan, which is similar to a traditional split system. However, it is designed to accommodate multiple refrigerant lines connected to the various indoor units and this is the primary difference between the to systems
Multi-split systems offer several advantages:
Overall, multi-split systems provide efficient and customizable cooling and heating solutions for buildings with multiple rooms or zones, offering comfort, space savings, flexibility, and energy savings.
