Why were split systems developed in HVAC systems?

Split systems in HVAC were developed to allow flexibility in component placement. This design separates the indoor and outdoor units, enabling installers to position the system components in a way that best suits the building's layout and the occupants' needs. The indoor unit can be placed in a more convenient location inside the building, while the outdoor unit can be positioned outside in a less obtrusive area, such as on a rooftop or a back patio.

This flexibility not only enhances installation options but also addresses performance issues, as positioning the outdoor unit in a shaded area can improve efficiency by reducing the load on the system. Additionally, this separation can lead to more efficient airflow and temperature control, as well as a reduction in noise levels within the living spaces.

In contrast, the other options do not fundamentally address the primary rationale behind the development of split systems. While reducing energy consumption can be a secondary benefit, it is not the main reason for their design. Keeping all components organized in one location is not feasible for split systems, as their inherent design is to split components between two locations. Enhancing aesthetic appeal may be a consideration, but it is not a driving factor in the functionality and efficiency that split systems aim to provide.
