A system component, typically installed on a vertical surface, circulates conditioned air throughout a designated space. This component houses a blower, heating and cooling elements, air filters, and dampers. An example would be a compact unit affixed to a hallway wall within a multi-unit dwelling, providing individual climate control.
Its utilization optimizes floor space and simplifies maintenance access. Historically, such components were large and floor-mounted, demanding dedicated utility rooms. Modern advancements have enabled more compact designs, leading to increased adoption in residential and commercial building designs. This configuration can lower installation costs and offers a less intrusive approach to indoor climate control.
