Adaptable HVAC unit base

摘要

An adaptable base of the HVAC unit can allow an HVAC unit to align and seal with multiple duct opening configurations. Such opening configurations may be different footprints in different HVAC systems, such as may be employed for example in different roof curbs of rooftop HVAC units. The adaptable base includes a base plate, a supply air duct opening, a return air duct opening, where there is at least one additional opening for one or both of the supply air opening and the return air duct opening. Each opening has a seal around its perimeter. A seal is also arranged and located on the base plate about a perimeter around the supply air duct opening(s) and the return air duct opening(s). A cover can be connected to close one or more openings that are not being used with the unit.
