Definitions
- the present invention relates to a ceiling-mounted type air conditioner and a method for controlling the same, and more particularly to a ceiling-mounted type air conditioner, which is capable of calculating a comfort degree of each of plural areas within a room and controlling a supply of the conditioned air into the room according to the calculated comfort degrees, thereby uniformly conditioning air in the room, and a method for controlling the air conditioner.
- Air conditioners are apparatuses capable of processing air and supplying the processed air into an indoor room, thereby uniformly conditioning air in the room.
- ceiling-mounted type air conditioners are widely used in many places such as restaurants, classrooms, etc.
- the ceiling-mounted type air conditioners which are attached to a ceiling of a room, can more uniformly condition air in the room.
- Fig. 1 is a schematic view of a conventional ceiling-mounted type air conditioner 1.
- the conditioned air from the ceiling-mounted type air conditioner 1 is uniformly supplied into the room by properly regulating angles of vanes a, b of the ceiling-mounted type air conditioner 1, thereby keeping the room temperature more uniform than any other type of air conditioner, such as a wall-mounted type air conditioner, etc.
- the room installed with the ceiling-mounted type air conditioner 1 has a window 2 on its wall, as shown in Fig. 1, as compared with an aisle-sided area adjacent to an aisle 3 opposite to the window 2, the room temperature around a window-sided area adjacent to the window 2 is more easily changeable. Therefore, with this conventional ceiling-mounted type air conditioner 1, it is difficult to uniformly maintain the room temperature throughout the room.
- the conventional ceiling-mounted type air conditioner 1 measures the room temperature, and controls the supplied air direction and velocity according to the measured room temperature. That is, the conventional ceiling-mounted type air conditioner 1 does not measure a temperature of each of plural areas within the room, but measures a temperature of one area, in which the ceiling-mounted type air conditioner 1 is installed, and controls the supplied air direction and velocity according to the measured temperature of this area. Therefore, the conventional ceiling-mounted type air conditioner 1 cannot offset the temperature differences among plural areas within the room.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide a ceiling-mounted type air conditioner comprising a radiation temperature sensor, and a method for controlling the ceiling-mounted type air conditioner.

- the radiation temperature sensor (S) has a sensing range of at least 120 degrees so that the radiation temperatures of a window-sided area and an aisle-sided area in the room can be measured.
- Fig. 4 is a plan view of a ceiling-mounted type air conditioner, in which the radiation temperature sensor is installed on the wind vane, in accordance with another embodiment of the present invention.
- the radiation temperature sensor (S) of the present invention may be attached to one out plural wind vanes 30 of the ceiling-mounted type air conditioner.
- the radiation temperature sensor (S) need not have the sensing range of at least 120 degrees. Nevertheless, the radiation temperature sensor (S) can measure the radiation temperatures of plural areas in the room.
- the radiation temperature sensor (S) moves from side to side by the motion of the wind vane provided with the radiation temperature sensor (S), thereby measuring the radiation temperatures of plural areas in the room. Therefore, the radiation temperature sensor (S) can measure the radiation temperatures of the window-sided area and the aisle-sided area according to the movement of the wind vane.
- the microcomputer of the ceiling mounted-type air conditioner calculates a comfort degree of each area of the room according to the measured radiation temperatures.

- the microcomputer 56 averages the radiation temperature measured by the radiation temperature sensor (S) and the room temperature measured by the room temperature sensor 55, thereby calculating the comfort degree of each area in the room. That is, the comfort degree of the window-sided area is an average value of the radiation temperature of the window-sided area and the room temperature. Further, the comfort degree of the aisle-sided area is an average value of the radiation temperature of the aisle-sided area and the room temperature.
- the microcomputer 56 compares the comfort degree of the window-sided area with the comfort degree of the aisle-sided area, and controls the motor 40 for driving the wind vanes according to the compared result, thereby regulating the angles of the wind vanes 30.
- the microcomputer 56 controls the motor 40 so that the supplied air toward the window-sided area increases, thereby properly regulating the angle of the window-sided wind vane. Further, when the comfort degree of the aisle-sided area is lower than that of the window-sided area, the microcomputer 56 controls the motor 40 so that the supplied air toward the aisle-sided area increases, thereby properly regulating the angle of the aisle-sided wind vane.
- the radiation temperature sensor measures the radiation temperatures of plural areas within the room by the driving of the ceiling-mounted type air conditioner.
- the microcomputer of the ceiling-mounted type air conditioner calculates the comfort degrees of the window-sided area and the aisle-sided area using the measured radiation temperatures.
- the comfort degree of the window-sided area represents an average value of the radiation temperature of the window-sided area and the room temperature.
- the comfort degree of the aisle sided area represents an average value of the radiation temperature of the aisle-sided area and the room temperature.
- the microcomputer of the ceiling-mounted type air conditioner confirms whether the comfort degree of the window-sided area is higher than that of the aisle-sided area or not.
- the microcomputer If the comfort degree of the window-sided area is lower than that of the aisle-sided area, the microcomputer then increases the supplied air toward the window by regulating the angle of the window-sided wind vane. (S5)
