Patent granted for a single-package air conditioner unit
A recently granted patent (Publication Number: US11774133B2) describes a single-package air conditioner unit with several innovative features. The unit includes a housing with an outdoor portion and an indoor portion, as well as an outdoor heat exchanger assembly and an indoor heat exchanger assembly. A compressor circulates refrigerant between the outdoor and indoor heat exchangers.
One notable feature is the inclusion of a plenum attached to the housing, which can be placed within a wall channel. The plenum has a primary air channel that allows air to flow between the outdoor and indoor portions. It also includes a make-up air (MUA) inlet that permits air to enter the indoor portion. An angled inlet plate within the plenum helps direct the air flow.
The unit also includes an intake conduit downstream from the MUA inlet, which defines an intake passage upstream from the indoor heat exchanger assembly. The intake conduit has a primary inlet and a secondary inlet, both of which allow air to enter separately.
Additionally, the plenum has an equalizing air (EA) exhaust that receives air downstream from the indoor portion. An angled exhaust plate within the plenum helps control the air flow in this area.
Another feature of the unit is the inclusion of an outdoor inlet and an outdoor outlet in the housing. These help facilitate the flow of air through the unit.
Overall, this single-package air conditioner unit offers several innovative features that improve air flow and efficiency. The inclusion of the plenum, angled inlet plate, and intake conduit with separate inlets allows for better control of air flow. The unit's design also helps facilitate the circulation of refrigerant and the overall cooling process.
