An integral air conditioner device is provided. The device has an air conditioner body, a condenser and an anti-blow-by structure. The anti-blow-by structure is a box body with openings on two sides of the box body. The opening on one side of the box body is in communication with an air inlet of the air conditioner body. The opening on the other side of the box body faces the condenser. The periphery of the opening that faces the condenser and a frame of the condenser are arranged in a closed manner. In the integral air conditioner device, the anti-blow-by structure is provided between the air inlet and the condenser and one opening of the anti-blow-by structure faces the condenser, such that air fed in through the air inlet can only pass through the condenser and is subsequently exhausted by an air outlet of the air conditioner body.

A single-package air conditioning appliance includes a housing defining an outdoor portion and an indoor portion. An outdoor heat exchanger assembly is disposed in the outdoor portion. The outdoor heat exchanger assembly includes an outdoor heat exchanger and an outdoor fan. An indoor heat exchanger assembly is disposed in the indoor portion. The indoor heat exchanger assembly includes an indoor heat exchanger and an indoor fan. A compressor is in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant between the outdoor heat exchanger and the indoor heat exchanger. The single-package air conditioner unit also includes a make-up air module. The make-up air module extends between the outdoor portion of the housing and an outside of the housing. The make-up air module includes a plurality of make-up air fans.

An air conditioner unit is configured for automatically detecting a restricted duct and adjusting fan speed schedules in response. The air conditioner unit includes an indoor fan including a drive motor for selectively rotating the indoor fan to urge a flow of air through the indoor portion and a controller is configured for sending a control signal to the drive motor to rotate the indoor fan to an actual fan speed. Based on the actual fan speed and a unit voltage, the controller obtains a target control signal, e.g., via a lookup table, and determines that a restricted duct condition exists if the control signal is different than the target control signal. The controller adjusts the operation of the indoor fan in response to determining that the restricted duct condition exists.

A floor-type air-conditioning indoor unit and an air conditioner are provided. The indoor unit has a housing, a top air outlet frame and a fan assembly. The housing has an installation port where the top air outlet frame is installed. The top air outlet frame is movable in an up-down direction and has a lower port and a front port. The fan assembly blows airflow from the air inlet to the lower port and out from the front port of the top air outlet frame. One of the top air outlet frame and the housing is provided with a sliding plate extending in the up-down direction, and the other is provided with a sliding groove engaging the sliding plate. A length of the sliding plate is longer than or equal to a maximum trip of the top air outlet frame in the up-down direction.

An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a fresh air inlet and a fresh air door movable to control fresh airflow through the fresh air inlet. The inlet subassembly further includes a recirculation air inlet and a partition defining a first airflow channel and a second airflow channel extending from the recirculation air inlet. A recirculation air door is adjacent to the recirculation air inlet and is movable to a closed position restricting recirculated airflow into both the first airflow channel and the second airflow channel, an open position permitting recirculated airflow into both the first airflow channel and the second airflow channel, and a two-layer position in which the recirculation air door restricts recirculated airflow into the first airflow channel and permits recirculated airflow into the second airflow channel.

A mobile air conditioner includes a housing includes an air outlet, and an air exhaust pipe detachably connected to the housing. The air exhaust pipe having a communication state and a storage state. In the communication state, the air exhaust pipe is connected to the housing and the air outlet is in communication with an outdoor environment through the air exhaust pipe. In the storage state, the air exhaust pipe is attached to the housing in a suspension manner after being detached.
