A pneumatic radiation air conditioner includes: a radiation unit configured to radiate air-conditioning air; and a fan configured to feed the air-conditioning air to the radiation unit. The radiation unit includes: a first chamber, through which the air-conditioning air flows; a second chamber configured to take in the air-conditioning air discharged from the first chamber and discharge the air-conditioning air and radiate heat of the air-conditioning air to a space to be air conditioned; and an air stream adjuster configured to adjust air velocity distribution and air volume distribution of the air-conditioning air that is discharged from the first chamber to the second chamber.

A window mounted air conditioning unit is disclosed. The A/C includes an indoor unit, an outdoor unit, and a bridge. The indoor unit and outdoor unit are operatively connected by a line set (electrical wiring, refrigerant piping, condensate drainage piping, communication wiring, etc.) that is flexible and extensible and that resides in the bridge. The bridge is extendable from a first position to a second position to accommodate window openings of varying thicknesses. The A/C appliance is mounted to a separate mounting bracket that is itself extendable for varying width openings. The outdoor unit is pivotally connected to the bridge so that the outdoor unit can assume a first orientation during installation through a window opening, and a second orientation after passing through the window opening.

An environmental control unit, such as an HVAC or heat pump unit, includes a housing which contains four main components: a blower which draws air into the housing via an air inlet and exhausts air from the housing via an air outlet; a first heat exchanger that exchanges heat through the air and is located between the air inlet and the blower; a second heat exchanger, which exchanges heat through water and is disposed in the second area of the housing; and a compressor. The environmental control unit having a predetermined set of parts can be arranged in multiple configurations to meet installation requirements, where configurations include air entering from the left side or, alternatively, from the right of the environmental control unit. The configurations utilize the same parts and provide front-facing access to fluid connections and the control board.

An air conditioner installable on a window frame and having a ventilation function. The air conditioner comprises a cabinet comprising a first inlet hole, a second inlet hole and a third inlet hole, a first heat exchanger provided inside the cabinet to allow indoor air, which is introduced through the first inlet hole, to exchange heat, a second heat exchanger provided inside the cabinet to allow outdoor air, which is introduced through the second inlet hole, to exchange heat, and a third heat exchanger provided inside the cabinet to be located between the first heat exchanger and the second heat exchanger in a height direction of the cabinet, and provided to allow outdoor air, which is introduced through the third inlet hole, and condensed water, which is generated in the first heat exchanger, to exchange heat with each other.

An integral air conditioner is provided. An electric control box of the air conditioner is split into at least a first box body and a second box body. The first box body is arranged between a first fan shell and a middle partition plate. The second box body is arranged below the middle partition plate. A first fan has a first fan wheel and the first fan shell. Since the first fan wheel rotates around a shaft, the first fan shell generally has an arc-shaped edge. A gap is presented between a surface of the first fan shell and the middle partition plate. The electric control box is split into multiple box bodies and constructed to match the shape of the first fan shell. The first box body of the multiple box bodies is arranged in the gap between the first fan shell and the middle partition plate.

The present invention discloses a base unit and a desktop cooling fan having the base unit, wherein the base unit comprises a base for detachably carrying a front panel unit, and/or a cooling unit, and/or an air supply unit mounting part, and/or a cover unit, and/or a refrigerant unit, and the base is formed with a lower liquid storage tank structure which can be closed. This freely disassembled and assembled structure provides flexible and convenient use performance. Meanwhile, the cooling device provided also effectively overcomes the problems of easy discoloration, aging, high noise, easy overflow of a refrigerant medium in use of the wet curtain of the existing apparatus.

A portable heating, ventilation, and air conditioning (HVAC) unit includes a housing, a plate, and a duct assembly. The housing defines a first airflow exit and a second airflow exit. The first airflow exit is separated from the second airflow exit by a portion of the housing. The plate is configured to cover the first airflow exit. The duct assembly is configured to cover the second airflow exit. The plate is configured to be disassembled from the housing and reassembled to cover the second airflow exit, and the duct assembly is configured to be disassembled from the housing and reassembled to cover the first airflow exit.
