摘要:
Provided is a ventilation device equipped with a housing, a heat exchanger installed in the middle of the inside of the housing, an indoor air exhaust port and an outdoor air suction port formed at one side of the housing based on the heat exchanger, an indoor air suction port and an outdoor air supply port formed at another side of the housing, an exhaust fan installed at one side of the interior of the housing for exhausting indoor air through the indoor air exhaust port to outside, a supply fan installed at another side of the interior of the housing for sucking outdoor air from outside and sending the outdoor air to the outdoor air supply port, and a brushless DC (BLDC) motor for driving the exhaust fan and the supply fan. The ventilation system includes a motorized damper installed at each of the indoor air exhaust port and the outdoor air suction port for adjusting the amount of indoor air exhausted by the exhaust fan and the amount of outdoor air sucked by the supply fan; an RPM sensor embedded in the BLDC motor to measure revolutions per minute (RPM); and a microprocessor configured to receive a signal regarding the RPM of the BLDC motor measured by the RPM sensor and adjust an opening ratio of the motorized damper.

An object of the present invention is to provide a control device for controlling the swing action of an air conditioning apparatus and improving the level of comfort within a room. A control device (4) is a control device (4) for controlling a swing action for causing flaps (22a-22d) of an air conditioning apparatus (1) to swing up and down, the control device (4) comprising an operation mode determining section (41a), a swing pattern storage area (42), and a control command generator (41 e). The operation mode determining section (41a) determines at least an air-cooling operation mode and an air-warming operation mode, which are operation modes of the air conditioning apparatus (1). The swing pattern storage area (42) stores a plurality of swing patterns which are varieties of information pertaining to the swing action. The control command generator (41 e) generates a control command of the air conditioning apparatus (1) on the basis of the swing pattern that corresponds to the result determined by the operation mode determining section (41a) from among the plurality of swing patterns.
摘要:
A system for controlling airflow in a plenum, that comprises a worm gear and planetary gear that are removably coupled to a worm shaft and planetary shaft, respectively. The planetary shaft controls the movement of a damper between an open position permitting maximum airflow through the plenum, and a closed position restricting airflow through the plenum. A motor or gear-motor is positioned at the plenum for driving the worm shaft. The motor is controlled by a remotely located controller that includes a power supply for operating the motor. The controller is connected to the motor through a cable with a detachable electrical connection between the cable and the controller. Alternatively, the movement of the damper is controlled by a drive shaft, which connects the motor or gear motor directly to the damper without intervening gearing. The motor is positioned in the airflow of the plenum. The cable may extend through the plenum to a diffuser or other opening in the plenum for connection to the controller, or may exit through a hole formed in the plenum.

An air conditioning unit includes a horizontal flap (10) ; a shaft formation member (14) including shaft portions (13) on both sides; a first shaft support portion (11L) that rotatably supports the horizontal flap (10); a second shaft support portion (11R) that rotatably supports the horizontal flap (10); and a support member (15) that is provided with a support shaft hole. One of the shaft portions (13) is inserted into the support shaft hole and supported at the appropriate location on the case between the first shaft portion (11L) and the flange portion (12), and the horizontal flap (10) is rotatably supported by inserting each of the shaft portions (13) into the first rotation shaft hole and the second rotation shaft hole respectively.

An air conditioner includes a main body portion in which an air outlet is formed and a main body side mounting hole is formed, a flap which is provided in the air outlet to change a direction of air blown from the air outlet, and a connecting member (21) which rotatably connects the flap with respect to the main body portion. The connecting member (21) includes a mounting hole insertion portion (25) which is inserted into the main body side mounting hole, a flap connecting portion (26) which is formed at one end portion of the mounting hole insertion portion (25) and is connected to the flap, and an elastic deformation portion (30) which at least partially swells radially outward from an outer circumferential surface of the mounting hole insertion portion (25) and is elastically deformable in the radial direction.

Provided is an air conditioner (1), including: at least one air inlet and at least one air outlet; a wall portion (11) ; an airflow direction flap; an air sending unit (17) ; and a heat exchanger (19) . The wall portion includes an inner air duct wall (41) and an outer air duct wall (43). The outer air duct wall is at a position more distant from the heat exchanger than the inner air duct wall. A distance between a center portion (43a) of the outer air duct wall in a longitudinal direction and a center portion (41a) of the inner air duct wall in the longitudinal direction is smaller than a distance between each side portion (43b) of the longitudinal center portion and each side portion (41b) of the longitudinal center portion of the inner air duct wall.
