An active grille shutter arrangement having an assembled modular frame with a plurality of primary frame pieces formed by extrusion. Each one of the plurality of primary frame pieces has a first end, a second end and at least one key slot extending between the first end and the second end. Each of the plurality of frame pieces also includes a hollow bore extending through the each one of the plurality of primary frame pieces forming an aperture at the first end and an aperture at the second end. When the modular frame is assembled there is an upper frame portion and lower frame portion, both formed from one of the plurality of primary frame pieces. The arrangement also includes a number of alternate frame and vane pieces that allow several different active grille shapes and configurations to be formed.

The presently disclosed subject matter is directed to a vent register for use with an HVAC system. The register is defined by a housing comprising top and bottom plates that are permanently joined to create an interior compartment. The interior compartment imparts an insulative quality to the register by providing resistance to an increase or decrease in temperature, such as when cooled air is flowing through the system. The interior compartment can be hollow and filled with air, foam, or any insulative material. In use, the register prevents or reduces the incidence of condensation forming on the face of the register during use.

An air-conditioning indoor unit and an air conditioner are provided. The indoor unit has a surface frame, a breezeless member, an outer deflector, a heat exchanger, and a fan. The surface frame has a first air outlet defined on a front lower part of the surface frame. The first air outlet penetrates a front part and a bottom of the surface frame. The breezeless member is disposed at a front side of the surface frame. The outer deflector is capable of opening and closing a bottom side of the first air outlet. The breezeless member is configured to open a front side of the first air outlet when located at a first position, and to close the front side of the first air outlet when located at a second position.

Disclosed is an air conditioner, and more particularly, to an air conditioner having an airflow guide to make the flow of discharged air uniform. An air conditioner comprising a housing having a suction port and a discharge port, a heat exchanger arranged inside the housing, a blower fan configured to suck in air through the suction port, force the air to be subject to heat exchange with the heat exchanger, and discharge the heat-exchanged air through the discharge port, a first blade pivotally arranged to open or close the discharge port and having a first face and a second face opposite of the first face, a first flow path formed between the discharge port and the first face, a second flow path formed between the discharge port and the second face, a second blade movably installed inside the housing and a third blade formed to protrude from the second blade to guide air to the first flow path and the second flow path.

An environmental control system for a building, the system including a vent. The vent includes one or more louvers configured to change position between an open position and a closed position to permit air from the air duct to enter a zone of the building or stop the air from entering the zone and a vent circuit configured to operate the one or more louvers based on one or more control commands. The system includes a controller device including a processing circuit configured to receive a selection of an operating profile from a plurality of predefined operating profiles for the vent, each of the plurality of predefined operating profiles indicating an intended use of the zone, determine, based on the operating profile, the one or more control commands, and cause the vent circuit to operate the one or more louvers based on the one or more control commands.

Disclosed are an air conditioner indoor unit and an air conditioner. The air conditioner indoor unit includes a housing, a volute assembly, an air deflector and a louver assembly. The housing is provided with an air outlet and the volute assembly is disposed in the housing. The volute assembly includes an upper volute and a lower volute forming an air outlet duct communicating with the air outlet therebetween. The air deflector is rotatably mounted at the air outlet to open or close the air outlet, and a middle portion of at least one end of the air deflector in a length direction is rotatably connected to the housing through a rotation shaft, to make the air deflector have an upward-opening state in which the air deflector is rotated around the rotation shaft to bring a lower side of the air deflector to come close to the upper volute and a downward-opening state in which the air deflector is rotated around the rotation shaft to bring an upper side of the air deflector to come close to the lower volute. The louver assembly is connected to a windward surface of the air deflector.
