Abstract:
An indoor unit of an air-conditioning apparatus includes an indoor imaging device that captures an image of inside a room, a thermal image detection device that acquires a thermal image of inside the room, an arithmetic operation device that acquires an air flow inside the room and that generates an air-conditioning status image obtained by superimposing the air flow obtained by the arithmetic operation and the thermal image acquired by the thermal image detection device on a visible image captured by the indoor imaging device, and a storage device that stores therein air-conditioning status images in accordance with the lapse of time. When a visualization button on a remote control is pressed, air-conditioning status images are transmitted to the remote control and are displayed as time-reduced moving images on a display unit of the remote control.
Abstract:
Air conditioner which can adjust a direction of an air-flow being discharged into a room. The air conditioner has blades for controlling the air flow direction and a connecting bar for connecting the blades such that the blades rotate together. The blades and the connecting bar can be reassembled. The air conditioner can adjust the flow direction of the air discharged from the air conditioner, thereby uniformly conditioning the inside of a room. In addition, even if hinge bars which connect the blades and the connecting bar are damaged, the blades and the connecting bar can be reassembled.
Abstract:
A room air conditioner is operable to perform heating or cooling operations in a room. Furthermore, it is possible to direct warm or cool air to selected regions of the room. For example, it is possible to carry out a distant mode of operation wherein warm or cool air is supplied to a distant region of the room, or a wide mode wherein the warm or cool air is directed across the entire width of the room. When either the distant mode or the wide mode is selected, a control mechanism of the air conditioner automatically resets the set temperature by either raising or lowering a fixed reference temperature (pre-programmed into the air conditioner controller). If a heating operation has been selected, the reference temperature is automatically increased by a predetermined amount, and during a cooling operation, the reference temperature is automatically reduced by a predetermined amount.
Abstract:
A temperature controlling apparatus adopting a fuzzy adaptation model and a method using the same are provided, in which temperatures of a plurality of positions of a refrigeration compartment are estimated in order to rapidly reach temperature equilibrium of the refrigeration compartment, by considering the operation states of a compressor and a cooling fan which directly affect the temperature of the refrigeration compartment. The temperature controlling apparatus adopting the fuzzy inference includes: a cool air discharge direction controller for controlling the rotation angle of a cool air discharge control blade; and a fuzzy inference unit for inferring peripheral temperatures of temperature sensors by taking the operational states of the cooling fan and the compressor as inputs, in order to provide the cool air discharge direction controller with information with respect to the static angle of the blades of the cool air discharge control blade.
Abstract:
An air conditioner has a flow directing vent comprised of slanted vanes. The vent is driven by a drive mechanism which oscillates the vent about an axis. The drive mechanism includes a motor driven shaft which rotates continuously in one direction, and a mechanism for converting such continuous rotation into oscillation of the vent. The drive connection between the vent and drive mechanism can be manually disconnected by axial displacement of the vent, to enable the rotational position of the vent to be adjusted relative to the drive mechanism.
Abstract:
A pneumatic fan containing a revolving wheel, which has a circumference, first and second stepped fillets at both axial ends thereof, and a rotary main shaft extending from the stepped fillets. The circumference is provided with a plurality of axially extending slots. The pneumatic fan further contains a plurality of impellers which are slidably received by the axially extending slots, each of the axially extending slots having a depth greater than the height of the impellers. Two shaft bearing seats are provided to receive the rotary main shaft at two axial ends thereof. The revolving wheel including the impellers are enclosed in a cylindrical motor seat having an entrance port for receiving air and an exit port for exiting air. The revolving wheel is disposed eccentrically relative to the motor seat, and the motor seat and the rotary main shaft have a point of contact, such that the entrance port and the exit port are disposed equidistantly from, and at opposite sides of, the point of contact. Two ring-shaped collars are provided to fit over the first and second stepped fillets, respectively. The first and second fillets are structured such that the collars are disposed eccentrically relative to the revolving wheel, and both collars are dimensioned such that the sum of its outside radius and the height of the impeller equal the radius of the motor seat.
Abstract:
A rotational speed of a fan is maintained at a preset one when an angle of a flap is at a maximum air-flow angle, increased by a specified value when the angle of the flap has been changed by a specified angle in the direction away from the position of the maximum air-flow angle, and decreased by a specified value when the angle of the flap has been changed by a specified angle in the direction toward the position of the maximum air-flow angle. It is possible to prevent any occurrence of condensation and air-flow pulsating noise without needing any complex control such as load response control and yet without requiring any complicate construction in the flap.
Abstract:
A thermally powered change over diffuser for controlling the flow orientation of air discharged from a ceiling mounted duct outlet includes a pair of vanes pivotably mounted on a platform for scissor-wise movement between an open and a closed position, and a thermally responsive actuator. Discharge of cooled air from the duct causes the actuator to move the vanes together into the closed position, blocking the center of the flow path, and forcing the discharge air to exit in a substantially horizontal orientation. Discharge of heated air causes the actuator to move the vanes apart, into the open position, allowing warm air to flow vertically downwardly into a building space.
Abstract:
There is disclosed an air-conditioner is provided with an indoor unit including a blower fan for a warm or cold wind to the interior of a room, a louver for adjusting the direction of blowing of warm or cold wind from the fan in a range from the ceiling to the floor, a controller for controlling a volume of wind blowing off from the fan, a temperature of a conditioned air, and an angular adjustment of the louver, respectively, and a console panel permitting switching between cooling and heating modes, setting of a temperature, and setting of various modes. A controller provided in this air-conditioner comprises a temperature shifter for setting a raised temperature higher than a set temperature by a predetermined value when a user present in a room and subject to delivery of a conditioned air sets a sleep mode for comfortable sleep during heating, and a louver controller for adjusting an angle of the louver so as to blow warm air having a raised temperature, in the ceiling direction of the room in the sleep mode during heating. With such a configuration, even when a user is going to sleep or is going to wake up, there is no possibility that warm air directly blows him or her. A comfortable air-conditioned environment, particularly when a user is lying close to the floor can be provided.
Abstract:
In an air conditioning apparatus of the separate-type, an indoor unit is mounted on a wall of a room. The indoor unit is provided with an infrared ray detection unit which has an infrared ray sensor for sensing infrared rays, a temperature sensor for sensing a temperature in the detection unit, and a slit window for restricting a field of view of the detection unit. The detection unit is horizontally swung with a discharge opening of the indoor unit, from which warm or cold air is discharged, so that the room is swept by the field of view and the air. The room temperature distribution is obtained from the output signal from the detection unit and, the amount of the discharged air directed to the respective areas of the room is adjusted in accordance with the room temperature distribution.
