Description

Air conditioning apparatus, vane control apparatus of air conditioning apparatus, and vane control method of air conditioning apparatus {air conditioning apparatus, vane controlling apparatus for the air conditioning apparatus, and vane controlling method for the air conditioning apparatus}

The present invention relates to an air conditioning apparatus. The present invention relates to a control apparatus and a control method for controlling the air discharged through the discharge port in an air conditioner having a plurality of discharge ports.

The air conditioner is a device for controlling the temperature and humidity of the air in the control space. In a narrow sense, the air conditioner refers to a device that sets the temperature of indoor air to a state desired by a user.

Recently, among the air conditioners, the ceiling type air conditioners installed and used in the ceiling are increasing in the indoor space. The ceiling type air conditioner is used more and more because it can be air-conditioned for the entire space of the room without occupying the indoor space.

The ceiling air conditioner is a general case in order to allow the indoor space to be air-conditioned as a whole, and has a plurality of discharge ports. In addition, the discharge angle and the reach distance of the air discharged through the plurality of discharge holes are controlled by controlling the vane angle placed inside the discharge hole. By doing so, the user can more conveniently hit the airflow of the air conditioning apparatus.

For example, in the auto mode, the air conditioner automatically moves the vane up and down so that the air intermittently reaches the position where the user is placed. However, when operated in this way, since the air flow to the user becomes intermittent, the user's convenience can be enhanced, but it is not preferable in terms of driving the air conditioner.

In detail, in the auto mode, the setting angle of the vanes placed at each discharge port is made to be equally matched to the plurality of discharge ports. In such a case, the flow resistance applied to the air passing through the discharge port is changed, and the flow rate of the air discharged as a whole is changed. Then, the flow rate of the air passing through the heat exchanger also changes, and the change in the flow rate passing through the heat exchanger leads to a change in the heat exchange capacity of the heat exchanger.

Such an operation not only causes a decrease in heat exchange efficiency, but also causes a problem in that efficiency of air conditioning for the indoor space is also reduced.

The present invention has been made to solve the above problem, and proposes an air conditioner, a vane control device of an air conditioner, and a vane control method of the air conditioner, in which the angle control of the vane becomes efficient.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the accompanying embodiments, and those skilled in the art who understand the spirit of the present invention can easily add, change, delete, add, etc. other components included in the scope of the same idea. It may be proposed, but this is also included in the spirit of the present invention.

1 is an exploded perspective view of an air conditioning apparatus according to an embodiment of the present invention. However, in Figure 1 is a view showing the installation state of the air conditioning unit upside down for convenience of understanding.

Referring to FIG. 1, the air conditioner of the present embodiment includes a case 1, a fan 2 accommodated inside the case 1, and a drain pan 3 placed in an open portion above the case 1. ), An orifice (5) provided at an inner portion of the drain pan (3), an orifice (5) provided at an inner opened portion of the suction guide (4) to smoothly introduce air, and A front panel 6 which forms the front surface of the device and separates the inside from the outside, and a suction grill 7 which covers some internal space of the front panel 6 and filters the air flowing in from the outside.

The suction grill 7 forms a suction end to which the outside air is sucked. Therefore, all the air flowing into the air conditioner passes through the suction grill 7.

The front panel 6 constitutes a front appearance of the air conditioning apparatus observed by the user, and constitutes a device for stably installing the suction grill 7, and further, guides the discharge of the discharged air. Discharge openings are provided at four corners of the front panel 6, and the discharge openings are provided with vanes 8, and the angle of the vanes 8 is controlled so that the position where the air discharged through the discharge openings is reached. Will be different.

The suction guide 4 and the orifice 5 is an article for stably introducing the outside air toward the fan 2 in a low noise state, both of which may be provided as a separate article as shown, Both may be provided in an integrated article.

The drain pan 3 serves to receive and store condensate generated in the heat exchanger and to discharge the condensate from the heat exchanger, and at four corners of the drain pan 3, a discharge port through which air discharged from the fan 2 passes is provided. It is prepared.

It will be understood that the fan 2 is connected to a motor to rotate the fan. In addition, it is natural that heat exchangers are disposed on four sides of the case 1 so that heat exchange is performed on the air and the refrigerant pipe.

The operation of the air conditioner will be briefly described with reference to the configuration as described.

When the fan 2 is rotated, a negative pressure atmosphere is formed in the inner space of the case 1. Then, the outside air is sucked through the suction grill 7, the orifice 5, the suction guide 4, and the fan 2 by the negative pressure inside the case 1. Then, the heat exchanged air passing through the heat exchanger is discharged to the outside through the discharge port of the drain pan (3), the front panel (6).

2 is a plan view of the air conditioning apparatus according to the present embodiment, in which a front panel of the air conditioning apparatus is shown.

Referring to FIG. 2, discharge holes 82 are formed at four corners of the front panel 6. And a vane 8 which adjusts to the flow direction of the air discharged through the discharge port 82 is provided in the opening part of the discharge port 82. FIG. The setting angle of the vanes is adjusted by a drive motor 81 installed on one side of the vanes 8.

In this case, the front panel 6 is provided in a quadrangular shape, and the discharge ports 82, the vanes 8, and the driving motors 81 are separately installed at respective portions of the rectangular corners. Therefore, the flow direction of the air discharged through each discharge port 82 can be adjusted individually.

3 is a cross-sectional view of the discharge port side of the front panel according to the present embodiment, the operation of the vane will be easily understood by FIG.

Referring to FIG. 3, a vane 8 is provided at the discharge end of the discharge port 82 formed in the front panel 6, and the vane may be rotated within a range of an angle. The change in the air conditioning environment according to the vane setting angle will be described.

First, when the vane 8 is set to 30 degrees, the flow direction of the air discharged through the discharge port 82 is bent in a large amount to flow along the ceiling. Then, while passing through the vane 8, the air receives a large flow resistance, and the flow resistance of the air passing through the discharge port 82 is also reduced by the flow resistance. In addition, the air discharged through the discharge port 82 is mainly guided along the wall surface of the ceiling, and then, after a predetermined distance, the air velocity decreases, and then gradually moves downward of the indoor space. As a result, the air volume felt directly by the user is reduced, but air conditioning can be performed in a comfortable environment.

On the contrary, when the vane 8 is set at 70 degrees, the flow direction of the air discharged through the discharge port 82 is discharged almost without bending. Then, there is little flow resistance of the air which air receives while passing through the vane 8, and there is almost no decrease in the flow rate. In addition, the user in the indoor space can directly feel the wind due to the strong wind speed. Then, the user can quickly feel the wind he wants.

Of course, the setting angle of the vane is not only 30 degrees and 70 degrees as described, but also various setting angles as the angle therebetween. In such a case, it can be operated with the advantages and disadvantages of each operation state mixed with each other.

In the present embodiment, the setting angle of each vane 8 corresponding to each discharge port 82 may be controlled differently. This is proposed in consideration of the fact that the flow resistance of the air discharged through the vane changes according to the set angle of the vane 8 and the amount of air discharged changes.

In more detail, four said vanes 8 are provided, and the operation | movement which rotates at the same angle up and down is performed. Then, while each vane 8 is rotating, the flow resistance applied to the air flow at the current vane angle is changed over time. However, according to the present embodiment, the sum of the flow resistances applied to the air discharged through the entire discharge port in which the vanes 8 are provided as a whole is equal.

In other words, although the flow resistance of the air discharged through any one discharge port 82 is different, the vane corresponding to each discharge port 82 is the same so that the sum of the flow resistances of the air discharged through the entire discharge port 82 is the same. The change of angle in (8) is controlled. By operating in this way, the amount of air passing through the heat exchanger of the air conditioner will be the same as a whole, and the amount of heat exchange by the heat exchanger may be the same even if the time changes. Then, the heat exchange efficiency in the heat exchanger can be set to the highest efficiency.

Thus, the state in which the highest efficiency is implemented in the heat exchanger will be described in more detail. For example, if the amount of heat exchanged in a heat exchanger changes over time, this means that the state of the refrigerant changes time-dependently. Thus, if the state of the refrigerant varies from time to time at each point of the air conditioning system, This, in turn, leads to an increase in irreversibility inside the air conditioning system. Naturally, the irreversible increase leads to a decrease in the efficiency of the heat exchange system.

In view of this problem due to such irreversibility, in this embodiment, although the set angle of the vanes varies with time, the flow resistance in the air applied by all the vanes at a specific time is the same. In this way, the amount of air passing through the heat exchanger can be constant in time, and the irreversibility of the heat exchanger can be reduced. In addition, it may be expected that the flow resistance is the same, for example, that the vanes are always constant when summing the open angles, but the present invention is not limited thereto, and this depends on various characteristics of the air conditioner. Will be.

In another aspect, even inside the space in which the air conditioner is installed, the maximum heat exchange effect that can be exchanged in the heat exchanger can be obtained. Therefore, maximum efficiency can be obtained even in an environment where air conditioning is required. Furthermore, in the case of a refrigeration system that compresses the refrigerant, the compressor can be operated at a constant speed, and thus, the advantage of operating more efficiently can be expected.

4 is a block diagram of the vane control device of the air conditioning apparatus according to the present embodiment.

Referring to FIG. 4, the air conditioner according to the present embodiment includes a controller 21 for controlling the air conditioner as a whole, a remote controller 22 for inputting user instructions to the controller 21, and the controller 21. The memory 23 stores and reads out various kinds of information necessary for the operation of the air conditioning apparatus, the vane motor 24 operated under the control of the controller 21, and the vane motor 24. A vane 25 for performing the rotational movement is included.

Of course, the air conditioner as a whole is not shown in FIG. 4, and other components may be additionally installed. For example, it is natural that the control state of various controllers such as a compressor, a motor, and the like can be controlled by the controller 21. However, other parts that are not described in this embodiment are to be applied to other methods widely known in the art, and only the components required for the implementation of the present embodiment will be described in detail.

The remote controller 22 is any item manipulated by a user and may be connected to the controller 21 by wire or wirelessly.

By the above-described configuration, the following operation can be performed.

First, the user operates the remote controller 22 to select the highest efficiency mode. Here, the highest efficiency mode is a mode in which the sum of induction resistances of the air passing through all the discharge ports does not change with time when the vanes rotate. Since the operation of increasing the operating efficiency of the air conditioning system in the highest efficiency mode has already been described, reference may be made to this.

Upon receiving the input of the highest efficiency mode from the remote controller 22, the controller retrieves the control data controlled by the vanes from the memory 23. There may be various types of control data recorded in the controller 23. Therefore, the user can retrieve a set of control data he wants from the control data, and operate the vanes accordingly.

For example, Fig. 5 shows an example of the control data of a preferred vane.

Referring to FIG. 5, when four discharge ports and vanes are provided, two vanes facing each other are always at the same set angle. In addition to this, as time passes, the vane angles change, and the vane angles may be set to alternate with each other. For example, when the pair of vanes 1 and 3 that are opposite to each other is 75 degrees, the pairs of vanes 2 and 4 that face each other in different directions may be set to 30 degrees. After the passage of time, the vanes 1 and 3 may be set to 30 degrees, and the vanes 2 and 4 may be set to 75 degrees. Of course, although the intermediate change state is not described in FIG. 5, the sum of the flow resistance of the air generated by the current vane angle can be set equally during the change.

As such, when the angle of the vanes is controlled, since the flow resistance may be the same in a symmetrical direction, vibration and noise that may occur due to asymmetry of the flow resistance may be eliminated.

6 illustrates another control data of the vane.

Referring to Figure 6, the angle of each vane is different. Therefore, vane 1 may be set at 75 degrees, vane 2 at 60 degrees, vane 3 at 45 degrees, and vane 4 at 30 degrees. After a certain time has elapsed, the vane angle is shifted so that vane 1 can be set to 30 degrees, vane 2 to 75 degrees, vane 3 to 60 degrees, and vane 4 to 45 degrees. Even in this case, the sum of the flow resistance of the air generated by the current vane angle can be set equally. As such, it will be readily appreciated that the highest efficiency mode can be implemented in the air conditioning system.

5 and 6 illustrate the vane angle control data while showing only the setting state of the vane angle as an example. However, not only the setting angle but also various data may be stored in the control data of the vane angle. For example, it may include a period in which the vane setting angle changes, and a limit range of the vane angle in which each vane is rotated. The data of FIGS. 5 and 6 may be stored together and may vary according to the user's selection and the air conditioner's own selection.

Referring back to FIG. 4, the control unit 21 drives the vane motor 24 with reference to control data read from the memory 23, and the vane motor 24 is connected to the vane 25. ) To change the flow direction of the air discharged through the discharge port 82.

The spirit of the present invention is not limited to the above-described preferred embodiments, and may further include the following embodiments.

First, although four discharge ports are described as being provided, the present invention is not limited thereto, and two or three discharge ports may be provided, such as two or three discharge ports and vanes.

In addition, in the above-described preferred embodiment, the case of the ceiling type air conditioner has been described as an example. However, the present invention is not limited thereto, and even if the air conditioner of another type is provided with a plurality of discharge ports, the idea of the present invention is applied as it is. It can be said.

According to the present invention, since the flow resistance of the air discharged through each discharge port does not change in the air conditioner provided with the plurality of discharge ports, it is possible to maximize the operating efficiency of the air conditioner. In addition, the air conditioning environment can be created in a desired state quickly inside the air conditioning area on which the air conditioning apparatus is placed.
