The indoor unit of a split system contains the space conditioning and air movement components, and the outdoor unit houses the heat-rejection devices. Īll components can be contained in one cabinet (e.g., rooftop unit as shown in Figure 1) or they can be housed in two cabinets (e.g., split systems as shown in Figure 2). Cooling is most often supplied by a direct expansion (DX) system, while heating can be provided by several system types, including gas (natural or propane), electric resistance, and heat pump (air-to-air). Unitary HVAC equipment can provide cooling or heating only, or both cooling and heating. Support organizations should budget and plan for regular maintenance to assure continuous operation. The purpose of this equipment O&M Best Practice is to provide an overview of unitary HVAC equipment, maintenance requirements, and best practices necessary to operate the systems safely and efficiently. Effective operations and maintenance (O&M) of these systems is necessary to maximize efficiency and production, provide occupancy comfort, and reduce failures. They are designed to be flexible so that the equipment can be installed indoors (in a mechanical room, attics, ceilings, etc.) or outdoors (on rooftops or on the ground). Unitary heating, ventilation, and air conditioning (HVAC) systems, which combine heating and cooling in one unit (packaged) or a few sections (split), are one of the most common technologies used for space conditioning in commercial buildings.
