A performance testing method of air conditioner, adapted to simultaneously test performance of indoor units and outdoor units on a production line for concurrently assembling the indoor units and outdoor units, the method comprising the steps of: firstly testing operability of indoor unit and leakage of outdoor units; connecting a communication line between the indoor unit and the outdoor unit; connecting a pipe between the outdoor unit and a dummy indoor unit; secondly testing a communicative operation between the indoor unit and the outdoor unit and operability of the outdoor unit; and comprehensively discriminating performances of the indoor unit and outdoor unit according to test data disclosed from the first and second testing procedures.

Performance testing method of air conditioner

An air conditioner includes an air inlet and an air outlet, an electric dust collector for removing dust from the air, a refrigerant-conducting heat exchanger for changing a temperature of the air, a fan for circulating air through the air conditioner, and an electrical heater which is energized when the fan and the electrical dust collector are energized, for heating the cleaned air. The electric dust collector communicates with only a lower portion of the air inlet. A closure mechanism for opening and closing the air inlet is operable to open only the lower portion of the inlet to insure that all of the air entering the air conditioner passes through the electrical dust collector during an air cleaning operation.

Methods and apparatus for controlling an air inlet closure of an air

An adaptable receiving frequency selection apparatus for a remote controller, and a method therefor, the apparatus including a remote controller receiving module for receiving the remote control signals transmitted from the transmitting unit and passing only signals falling within a predetermined frequency range, a control unit for searching for external electromagnetic wave components existing within a carrier frequency range of the remote control signal received through the remote controller receiving module, and for selecting another frequency range exclusive of the external electromagnetic wave components as a receiving frequency range, a D/A output unit for changing the frequency range over which the remote controller receiving module can receive the remote controller signals under the control of the control unit, and a display unit for displaying the frequency range selected from the control unit.

Apparatus and method for adaptable receiving frequency selection in a

An air conditioner includes a manual control panel for enabling a user to select from among a number of operating modes, including respective areas of a room to receive discharged air from the air conditioner. In accordance with the selected mode, there occurs an automatic adjustment of the orientation of air-directing vanes and the speed of an air discharge fan. The vanes can be adjusted to stationary positions, or can be oscillated.

Discharged air current control apparatus of air conditioner and method

A discharge current control apparatus of an air conditioner and method thereof having a plurality of suction inlets for sucking an indoor air, a heat exchanger for heat-exchanging the indoor air sucked through the suction inlets, a discharge outlet for discharging the air heat-exchanged by the heat exchanger, a plurality of wind direction blades for controlling a wind direction of the air discharged through the discharge outlet, and an indoor fan for controlling a wind amount of the air discharged through the discharge outlet, the apparatus comprising a distance detecting unit for sensing a human body nearness distance by detecting infrared generated from a human body, a position detecting unit for sensing a human body left and right position by detecting infrared generated from a human body, a control unit for controlling a wind direction, a wind amount, and a predetermined temperature of the discharged air, so that the discharged air can be supplied to an area where the human body exits according to the human body nearness distance sensed by the distance detecting unit and the human body left and right position sensed by the position detecting unit, a wind direction control unit for controlling a wind direction of the discharged air according to the control of the control unit, and a wind amount control unit for controlling a wind amount of the discharged air according to the control of the control unit.

Discharge current control apparatus of air conditioner and method thereof

An air conditioner discharges air through an air outlet and into a room. The direction of the discharged air is controlled by adjusting horizontal and/or vertical blades extending across the air outlet. The air flow rate can be controlled by adjusting a variable speed fan. Infrared sensors detect human bodies in the room and determine a distance and direction of the bodies with respect to the air conditioner for controlling the blades and fan in order to supply air to a region(s) of the room in which a human body is detected.

Methods and apparatus for controlling the direction and flow rate of air

A room air conditioner includes an air inlet, an air outlet, a heat exchanger disposed between the inlet and outlet, and an air circulation fan. The inlet is opened and closed by motor-driven inlet vanes. The outlet is opened and closed by a vertically slidable motor-driven door. Air direction control vanes extend across the outlet for varying the direction of discharged air. Before the door is either opened or closed, the air control vanes are automatically swung upwardly to a clearance position to avoid interfering with movement of the door. When the inlet and outlet are to be closed, the inlet vane motor is actuated prior the door motor to ensure that the inlet and outlet are fully closed simultaneously, even though it takes longer for the inlet vanes to travel to their fully closed state. A sensor determines when the door reaches an almost-closed state, and the door motor continues to operate for a set period thereafter to ensure that the door becomes fully closed.

Room air conditioner having inlet and outlet closures and methods for

An air conditioner includes an air inlet, an air outlet, and a heat exchanger. The air outlet has adjustable air direction control blades extending thereacross enabling a direction of discharged air to be set by a user. The blades are adjusted by a motor. When the air conditioner is shut-off, a controller memory stores the position of the blades and then moves the blades to a closed state. Upon re-starting the air conditioner, the controller drives the motor to return the blades to their previous (memorized) position.
