A split system air conditioner consists primarily of two main components: the indoor evaporator unit and the outdoor condenser unit. This system is designed to separate the components that cool the air from those that release the heat outside.

The indoor unit is responsible for absorbing heat from the indoor air, cooling it down, and then circulating the cooled air back into the space. It also houses the evaporator coil, which is essential for the cooling process.

The outdoor unit contains the condenser coil and the compressor. The compressor compresses the refrigerant, which then travels to the condenser coil where it releases the heat absorbed from the indoor air and condenses back into liquid form.

This separation into two distinct units allows for more efficient operation and is a key feature of split systems, making them popular in residential and commercial applications. The other choices focus on individual components or systems that do not encompass the primary structure of a split system.
