TECHNICAL FOR CONTROLLING BLOWOFF DIRECTION OF AIR-CONDITIONER USED BOTH COOLER AND HEATER}

The present invention relates to a control method for controlling the air direction of a combined air-conditioning and air conditioner, and more specifically, a plurality of temperature sensors are installed in a space where an air conditioner is installed, and the temperature of each point input from the temperature sensor is determined to be intensively blown to a weak point. The present invention relates to a control method of wind direction control of a combined air-conditioning and heating system to achieve balanced air-conditioning at all points by adjusting vertical and horizontal wings.

In general, the air conditioner uses the phenomenon of absorbing the surrounding heat when the liquid evaporates, and performs cooling as well as dehumidification. By the way, in the case of air-conditioning combined air-conditioning and cooling and heating, the circulation path of the refrigerant is reversed so that the heat is absorbed and released into the room during the heating operation, and the heat is absorbed and released into the outdoor during the cooling operation. .

As the frost is formed on the outdoor heat exchanger coil during the evaporation process of absorbing the surrounding heat in the outdoor heat exchanger during the heating operation of the combined air-conditioning and air conditioning, the defrosting operation is performed to remove the frost.

1 is a refrigerant circulation diagram of a general air-conditioning combined air conditioner.

As shown here, the outdoor unit 20 includes a compressor 210 for compressing a refrigerant, and four sides 240 for changing a circulation path of the refrigerant at an output end of the compressor 210. In addition, an outdoor heat exchanger 40 having one side connected to the four sides 240 to heat exchange outdoors, and an indoor heat exchanger 30 having one side connected to the four sides 240 performing heat exchange indoors, and indoor heat exchange The pressure reducing device 50 is provided between the other side of the device 30 and the other side of the outdoor heat exchanger 40.

In addition, the indoor heat exchanger (30) is provided with an indoor temperature sensor (110) for measuring the indoor temperature, and an indoor heat exchanger coil temperature sensor (120) for measuring the coil temperature of the indoor heat exchanger (30). 40, an outdoor temperature sensor 260 for measuring an outdoor temperature and an outdoor heat exchanger coil temperature sensor 270 for measuring a coil temperature of the outdoor heat exchanger 40 are installed.

Looking at the coolant net environmental path of the air-conditioning combined air conditioning as described above are as follows.

First, during the cooling operation, that is, the refrigerant compressed by the compressor as shown by the solid arrow is flowed into the outdoor heat exchanger 40 as the path is set to flow from the four sides 240 to the outdoor heat exchanger 40. After dissipating the heat is sent to the decompression device 50, and again to the indoor heat exchanger (30) is evaporated in a gaseous state in the liquid state is made of heat exchange to absorb the surrounding heat is made through the compressor again through the four sides (240) Sent to 210 to cycle.

At this time, since the indoor heat exchanger 30 installed in the room absorbs the surrounding heat, the room is cooled.

Next, during the heating operation, the refrigerant compressed by the compressor 210 flows to the indoor heat exchanger 30 as the refrigerant flows from the four sides 240 to the indoor heat exchanger 30 as shown by the dotted arrow. After the heat is released to the decompression device 50 is sent to the outdoor heat exchanger 40 again evaporated in the gaseous state in the liquid state is made of heat exchange to absorb the surrounding heat is made through the four sides (240) It is sent back to the compressor 210 to circulate.

At this time, since the heat contained in the refrigerant is released from the indoor heat exchanger 30 installed in the room, the room is heated.

Such an air conditioner is provided with a discharge grill for discharging air cooled and heated. The discharge grill has a plurality of horizontal wings operated by an induction motor so as to control the wind direction of cold and warm air from the inside of the indoor unit in the vertical direction as a wind direction control device. Are rotatably mounted, and a plurality of vertical wings operated by an induction motor are rotatably mounted to control the direction of cold and warm air in left and right directions.

Therefore, the plurality of horizontal blades and vertical blades mounted in this way guide the discharge direction of the cold air. The switch is fixed at a predetermined angle according to the user's selection, or is repeatedly rotated over a preset angle (typically ± 80 °). I'm driving.

However, if the wind direction control device for guiding the cold and warm air as described above is randomly swinging or fixed at a constant angle range, the entire indoor space is not uniformly heated and heated, but only a certain part is cooled and heated. There is a problem that the heating and cooling is not achieved.

The present invention has been made to solve the above problems, the object of the present invention is to install a plurality of temperature sensors in the space in which the indoor unit is placed and to determine the temperature of each point input from the temperature sensor to focus on the weak point The present invention provides a control method for controlling the air direction of a combined air-conditioning and air conditioner to achieve balanced air-conditioning at all points by adjusting the vertical wing and the horizontal wing to be blown.

Figure 2 is a block diagram showing the indoor unit wind direction control device of a combined air conditioning and air conditioner according to the present invention.

As shown here, the vertical wing drive unit 340 for rotating the vertical wing 345 for adjusting the discharge direction of the cold air heater in the left and right directions, and the horizontal wing 355 for adjusting the discharge direction of the cold air heater in the vertical direction. A horizontal wing drive unit 350 for rotating), a plurality of temperature sensors 300 installed in a space where an air conditioner is installed, a receiver 320 for receiving indoor temperatures measured by the plurality of temperature sensors 300, and a user arbitrarily. To control the vertical wing driver 340 and the horizontal wing driver 350 according to the input signal input unit 310, the receiving unit 320 and the signal input unit 310 to adjust the discharge direction of the cold and warmer. It consists of a control unit 330 for.

At this time, the plurality of temperature sensors 300 is composed of at least three or more installed in various places where the indoor unit is installed, the measured temperature value is wirelessly transmitted to the receiver 320.

Referring to the flow chart shown in Figure 3 the control method of the wind direction control device for a combined air conditioning and air conditioner according to the present invention made as follows.

It is determined whether the wind direction controller is set to the automatic mode or the manual mode (S10).

At this time, when the manual mode is set, the vertical blade driver 340 and the horizontal blade driver (340) in the control unit 330 according to the angle of the vertical blade 345 and the horizontal blade 355 input by the user through the signal input unit 310 ( 350 to control the discharge direction of the cold and hot air.

However, if the automatic mode is set, it is determined whether the cooling operation or the heating operation is performed (S30). Therefore, the area vulnerable in the case of heating operation is a region lower than the set temperature or the lowest region in the temperature value input from the plurality of temperature sensors 300. In addition, the area vulnerable in the case of the cooling operation is a region higher than the set temperature or the highest region in the temperature value input from the plurality of temperature sensors 300.
