The system also includes a controller that receives information about the environmental variables and a desired set point for the environmental variable in the space. The controller determines a target airflow to achieve the desired set point and transmits information about the target airflow. The register receives information about the target airflow and controls the register adjusting mechanism to achieve the target airflow. | 05-14-2015 |
20160084516 | Control Method for Air Deflectors of Air Conditioner - Disclosed is a control method for air deflectors of an air conditioner. The air deflectors are arranged at an air outlet of the air conditioner to adjust directions of discharged air. The control method comprises: during the air conditioner is operating in a refrigeration mode, judging whether a motion instruction for swinging air is input or not; when the motion instruction for swinging air is not input, acquiring a set air volume level, set temperature T1 and indoor ambient temperature T2; according to the set air volume level, the set temperature T1 and the indoor ambient temperature T2, judging the amount of a refrigeration demand of a user; and according to the amount of the refrigeration demand of the user, controlling an air guide angle of the air deflectors. | 03-24-2016 |
20160123621 | Fully Close Vent Device for Heating and Air Conditioning System - A vent device includes a vent frame and a fin arrangement. The vent frame includes a ventilating opening and a peripheral frame portion adapted for mounting at an air outlet of a heating and air conditioning system. The fin arrangement includes a plurality of vent fins longitudinally and rotatably supported at the ventilating opening, wherein each of the vent fins has first and second longitudinal sealing edges. When the vent fins are concurrently moved in an opened position, the vent fins are rotated to parallel with each other for allowing air passing through. When the vent fins are concurrently moved in a closed position, the first longitudinal sealing edge of each of the vent fins is overlappedly engaged with the second longitudinal sealing edge of the adjacent vent fin to completely seal the ventilating opening of the vent frame in an air sealing manner. | 05-05-2016 |
