The present disclosure relates to an air cleaner. The air cleaner according to an embodiment of the present disclosure includes: a case having a discharge port which is formed on an upper side thereof and is vertically open; a blower fan disposed inside the case, and causing air inside the case to flow to the discharge port; a discharge guider disposed on the upper side of the case where the discharge port is formed, rotating about a rotation axis formed in an up-down direction, and changing a wind direction of air discharged through the discharge port; and a motor rotating the discharge guider, wherein the discharge guider includes a plurality of grills which are bent in a first direction perpendicular to the up-down direction, and are spaced apart from each other in the first direction.

An air cleaner includes a blower, a circulator disposed over the blower, and a mover coupled to the circulator and configured to change an arrangement of the circulator. The circulator includes a lower cover, an upper cover disposed over the lower cover, a blower fan rotatably disposed between the lower cover and the upper cover, a motor disposed on an upper side of the lower cover and rotating the blower fan, an inner cover disposed over the lower cover and receiving a lower portion of the blower fan, and a bell mouth protruding upwardly from an inner circumferential end of an inner plate of the inner cover and spaced apart outwardly from a circumferential surface of a suction guider of the blower fan, so as to guide air, drawn in through an inlet of the lower cover, toward an inlet of the blower fan.

An air cleaner includes: a blower having an outlet formed on an upper side thereof; a circulator disposed over the blower and configured to control a wind direction of air flowing upwardly through the outlet; and a mover coupled to the circulator and configured to change an arrangement of the circulator, wherein the circulator includes: a lower cover having a lower plate coupled to the mover, and having an inlet formed around the lower plate; an upper cover disposed over the lower cover and having an outlet; a blower fan rotatably disposed between the lower cover and the upper cover, and having a circular inlet formed on a lower side and an annular outlet formed on an upper side; and a motor disposed on an upper side of the lower plate, and rotating the blower fan.

An air cleaner includes a first blowing device having a first inlet and a first outlet, a second blowing device disposed above the first blowing device and having a second inlet, and a partition plate disposed between the first outlet and the second blowing device. The first blowing device includes a case forming the first inlet and opened in an upper side, a discharge guide device disposed in the opened upper side of the case and forming the first outlet, a first fan disposed inside the case and forming an air flow from the first inlet to the first outlet, and a splitter disposed between the partition plate and a discharge guide device and extending upward from the discharge guide device in a radial direction of the discharge guide device to separate an air flow discharged from the first outlet and guide the air flow in the radially outward direction.

An air circulator includes a housing having a first inlet and a first outlet, an oblique-flow fan disposed in the housing, and a motor rotating the oblique-flow fan. An outer wall of the housing includes a first outer wall extending in a front-rear direction and a second outer wall having the first inlet and extending from an edge of the first inlet towards the first outer wall to be enlarged in a radially outward direction. An outer surface of the second outer wall comprises a first surface that extends towards the first outer wall to be rounded outwards, and forms a surface continuous with an outer surface of the first outer wall, thus guiding air flowing along an outside of the first inlet so that the air flows forwards along the outer surface of the first outer wall.

Methods and related systems are disclosed for retrieving personality data for a first unit a climate control system. In an embodiment, the method includes querying a second unit controller that has replaced the first unit controller. In addition, the method includes determining that the second unit controller lacks personality data that is unique to the first unit. Further, the method includes transferring the personality data to the second unit controller from a memory of the climate control system that is separate from the second unit controller.

The present invention provides a practical method for treating atopic dermatitis. By subjecting patients suffering from atopic dermatitis to filtered temperature controlled laminer air flow disease symptoms have been significantly reduced and even removed. The velocity of the laminar air flow is balanced such that body convections are braked without the generation of draught..

Portable body cooling apparatus, particularly wearable on subjects, the apparatus comprises a channeled assembly including a coupled pair of channels longitudinally extending adjacent to each other, and wearable along outer contour of a subject's body part. The apparatus also comprises a forced air flow assembly connected to channeled assembly, for generating and driving forced flow of air into and through channeled assembly and facilitate indirect evaporation of liquid inside the channeled assembly, so as to produce forced flow of cool air exiting from channeled assembly and directed onto the subject, thereby cooling the subject. Also disclosed is a corresponding method of cooling a subject.

A control system for controlling a heating ventilation and air conditioning (HVAC) system, uses a thermal comfort model (TCM), an airflow dynamics model (ADM) and an HVAC model connecting thermal states at air vents with states of actuators of the HVAC system, for determining a target thermal state at the air vents connecting the HVAC system to an environment, such that the target thermal state at the air vents results in a thermal state at the location of an occupant according to the ADM connecting uneven distribution of thermal states at different locations in the environment. Further, the control system determines and submits control commands to one or multiple actuators of the HVAC system producing the target thermal state at the air vents.
