A sealed system and a method of assembling the sealed system include installing an expansion device such as an electronic expansion valve (EEV) between an indoor heat exchanger and an outdoor heat exchanger. Before or after the expansion device is installed, a predetermined stop position of an adjustable valve is determined, e.g., based on the sealed system capacity. A removable motor assembly moves the adjustable valve to the predetermined stop position and the adjustable valve is permanently fixed within the expansion device, e.g., by removing the motor assembly and/or melting a locking member positioned within the expansion device.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

A packaged terminal air conditioner unit includes an inlet conduit coupled to a compressor at an accumulator of the compressor. An outlet conduit is coupled to the compressor at a discharge of the compressor. The discharge of the compressor is positioned at a top portion of the compressor. The outlet conduit extends upwardly along a vertical direction from the discharge of the compressor between a pair of angled segments of the inlet conduit. The pair of angled segments of the inlet conduit is positioned above the compressor along the vertical direction.

The present invention, high efficiency flipping window-bridge air conditioners and heat pumps, generally relates to air conditioners and beat pumps. It follows the same operating theory as that of ductless mini-split air conditioners and heat pumps currently on the market. The main advantages of the current invention are high efficiency and easy installation. What is invented is that an indoor unit and an outdoor unit are linked via a frame as one package before the package is mounted and installed in a window opening. The outdoor unit is flexibly connected to the frame by joints and bars; thereby, the outdoor unit is flipped from a horizontal position to a downward vertical position and vice versa, and remain secured in the downward vertical position. The indoor unit is slidably connected to the frame by sliding chutes.

An indoor unit for an air-conditioning unit that can prevent dew condensation on an air-flow-direction control plate in a vicinity of a heat exchanger, and includes a casing, an air inlet on the casing, an air outlet opening in a bottom surface of the casing, a heat exchanger in an air passage extending from the air inlet to the air outlet, a fan on a windward side of the heat exchanger in the air passage, and an air -flow-direction control plate in the air passage between the heat exchanger and the air outlet. The heat exchanger includes a plurality of heat exchanger blocks arranged in a front-and-rear direction of the casing, and includes a refrigerant inlet through which refrigerant flows into the heat exchanger, and a refrigerant outlet through which the refrigerant flows out of the heat exchanger. The air-flow-direction control plate is provided in the vicinity of one of the heat exchanger blocks, the refrigerant outlet is provided in a heat exchanger block other than the heat exchanger block provided in the vicinity of the air-flow-direction control plate, and the number of refrigerant outlets is larger than the number of refrigerant inlets.

Provided is an air conditioner having an ion generation device, the ion generation device including a main body including an electrode structure that includes a discharge electrode and a ground electrode, a coupling part disposed on at least one surface of the main body, the coupling part being coupled to the case, and an ion discharge part disposed on the main body to discharge the ions generated when a high voltage is applied to the electrode structure.

Air conditioner units and methods of operating the same are provided. A method of operating an air conditioner unit includes activating a makeup air system of the air conditioner unit. The makeup air system directs a flow of outside air from the makeup air system to an indoor portion of a housing of the air conditioner unit. The method also includes activating an indoor fan disposed in the indoor portion of the air conditioner unit at a fan speed at least equal to a minimum circulation threshold speed in response to the makeup air system being activated. Activating the indoor fan causes the flow of outside air from the makeup air system to be urged through the indoor portion of the housing. An air conditioner unit may include a controller, and the controller may be configured for performing the method.

A measuring system includes a temperature-variable container, an optical device and an air conditioner. The temperature-variable container includes a transparent plate. The optical device includes a first optical sensor unit and a second optical sensor unit. The air conditioner is disposed between the transparent plate and the optical device.

A fragrance delivery apparatus contains: a body, a fan, a power base, and a case. The body includes an accommodation chamber defined therein, a receiving groove formed above the accommodation chamber, an air vent arranged on a first side of the body and communicating between the accommodation chamber and the receiving groove, and multiple elongated orifices formed on a second side of the body opposite to the first side of the body and communicating with the accommodation chamber. The fan is accommodated in the accommodation chamber and draws external gas from the multiple elongated orifices. The power base is connected with the body and shields the accommodation chamber, and the power base is configured to supply power and is electrically connected with the fan. The case is removably connected outside the body and includes a spray nozzle which is in communication with the receiving groove.

A dehumidifier includes a cabinet, a compressor, an evaporator, a condenser, and a fan. The cabinet is configured to be installed between studs in a wall. The evaporator is installed within the cabinet above the compressor. The condenser is installed within the cabinet above the evaporator. The fan is installed between the evaporator and a back surface of the cabinet. The fan is configured to generate the airflow that flows into the cabinet through the evaporator and out of the cabinet through condenser. The airflow flows through the evaporator and condenser in order to provide dehumidification to the airflow.
