As is known, the WiFi wireless LAN standard is advantageous in that it is excellent in security, has low possibility of confusion, has a relatively high communication speed, and is advantageous in that the communication device is less expensive than other communication methods by using a general purpose communication device.

As shown in FIG. 1, the wireless access APs 600 may be connected to the wireless communication module 500 of the fan coil units 400 while communicating with each other in a plurality of configurations according to states in the setting area.

In addition, as shown in FIG. 3, the wireless access APs 600 may be connected to each other in a wired LAN when wireless communication between the wireless access APs 600 is impossible due to the obstacle (a).

The control panel 700 is installed in a setting area such as a floor or a room of a building and is configured to remotely control the controller 450 of the fan coil unit 400 through the wireless connection AP 600 and the wireless communication module 500 Element.

The control panel 700 includes a smart phone, a tablet computer, or a notebook computer connected to the wireless access AP 600 via a wireless network. The control panel 700 includes network addresses # 1 and # 2 corresponding to the respective fan coil units 400 , # 3 ..) are attached to the fan coil units 400, the fan coil units 400 may be individually or group-controlled.

Accordingly, the remote control system of the present invention can design various types of user input and output.

The central server 800 is a component that controls the operation of the fan coil units 400 while at the same time controlling the operation of the control panel 700 centrally.

The central server 800 may be installed in a control room of a building and connected to the wireless connection APs 600 through a network hub 750 as shown in FIG. 450) while controlling the room temperature in the setting area.

In addition, the central server 800 controls the operation of the control panel 700 by the user by controlling the control panel 700 in each setting area.

Accordingly, the central server 800 can remotely control the operation states of the fan coil units 400 in the control room of the building, and can prevent excessive cooling and heating by the user while controlling the operation of the control panel 700 .

Meanwhile, the remote control system of the fan coil unit using the wireless LAN of the present invention may further include the directional antenna 900 as shown in FIG.

The directional antenna 900 is a component for controlling the fan coil units 400 installed in another setting area through the central server 800. [

4, the directional antennas 900 are respectively installed in buildings having different setting areas, and are installed in the form of facing each other while being connected to the wireless access APs 600. Accordingly, And allows control through the central server 800 while connecting the access APs 600.

Accordingly, the central server 800 can control the fan coil units 400 of another building in the control room via the directional antenna 900. [

The heat exchanging member 430 constituting the fan coil unit 400 of the present invention may include a coil 431 and a radiating fin 432 as shown in FIG.

The coil 431 is formed of a plurality of tubes and cools or heats the air while flowing the fluid.

As shown in FIG. 5, the radiating fins 432 are stacked in a state of being separated by passing through the coil 431 to dissipate heat or cool air of the coil 431.

Meanwhile, the coil 431 may be formed as an elliptical cross-section as shown in FIG. 6, and may have an oblong coil having a long axis in the moving direction of the air.

The air contact coil 431 can expand the thermal contact area with the air to improve the cooling and heating efficiency of the air and prevent the air flow at the rear end of the coil from being vortexed, thereby preventing scattering of condensed water during cooling.

For example, the coil having a circular cross section has a narrow thermal contact area with the moving air. In particular, since the outer peripheral surface of the rear end, through which the air escapes toward the discharge port 412, has almost no contact with air, And the water droplets formed therein are scattered toward the discharge port 412 by the swirling phenomenon of air while flowing along the outer circumferential surface of the thermal contact coil 431.

On the other hand, since the thermal contact area of the elliptical type of the oblique coil 431 with respect to the moving air extends to the discharge port 412, the water generated in the outer circumferential surface is minimized in the form of water droplets, and even if water drops are formed, And flows downward.

The oval coil 431 of the present invention smoothly cools or heats the air by the blowing fan 420, and particularly reduces the scattering of moisture generated during cooling to the outlet 412.

As described above, when the heat exchange member 430 is composed of the oval coil 431 having an elliptical cross section having the major axis in the moving direction of the air, the scattering of the condensed water is prevented, (420) can be employed, so that a device of high efficiency and large capacity can be realized.

Here, the casing 410 is provided with a drain (not shown) for discharging the condensed water.

Meanwhile, the heat dissipation fins 432 may be stacked while being spaced apart from each other through the configuration of the spacer as shown in FIG.

For example, the spacer may be composed of the projecting pipe 433 as shown in Fig.

As shown in FIG. 5, the protruding pipe 433 protrudes in a tubular shape at the penetrating portion of the oval coil 431 and is caught by another heat radiating fin 432, which is the same body as the radiating fin 432.

That is, the radiating fins 432 are inserted in the stacking state in the oval coil 431 through the protruding pipes 433, and are spaced apart from the protruding pipes 433 by the protruding pipes 433 of the other radiating fins 432 And the air is heated or cooled while the air is passed through the space.

In addition, the heat exchange member 430 may further include a moisture scattering prevention guide 480 as shown in FIG.

The moisture scattering prevention guide 480 interferes with the condensed water on the surface of the heat exchanging member 430 which moves together with the air due to the excess wind speed of the air blowing fan 420 during cooling and splashes water to the outlet 412 .

For example, the moisture scattering prevention guide 480 may include a pair of shield plates 481 installed on the heat radiating fins 431 in an adjacent state to the oval coil 431 and the protruding pipe 433 as shown in FIG. 7 .

As shown in FIG. 7, the pair of shield plates 481 are symmetrically disposed about the long axis of the oval coil 430 having an elliptical cross section, Thereby forming an inclined surface.

That is, the shield plate 481 forms an inclined surface on the side of the discharge port 412 of the oval coil 430, so that moisture is discharged to the discharge port 412 due to the excess wind speed while interfering with the air contacted with the outer peripheral surface of the oval coil 430. .

As shown in FIG. 7, the shield plate 481 includes an inlet portion 481a having a shape in which the mutual intervals of the inclined planes are narrowed, and a discharge portion 481b having a wide interval between the inclined planes. The flow rate of the air is varied to smoothly discharge the air.

That is, the air having passed through the oval coil 430 flows into the inflow portion 481a along with the moisture. As the distance between the inclined surfaces becomes narrower, the flow velocity increases, and the discharge portion 481b, So that the cross-sectional area is expanded to be smoothly discharged to the discharge port 412.

Meanwhile, the fan coil unit 400 of the present invention may further include a warming member 440 as shown in FIG.

The warming member 440 may be installed in the communication space 413 adjacent to the heat exchanging member 430 and the outlet 412 as shown in Figure 2 and may be connected to the central server 800 or the control panel 700, Is a component for further heating or cooling the air heat exchanged by the heat exchange member 430 while being operated by the heat exchange member 430. [

For example, the heating member 440 is composed of a thermoelectric element 441 and a thermally radiating fin 442, as shown in Fig. 8, which further heats or cools the air while generating heat or absorbing heat.

The thermoelectric element 441 utilizes the Peltier effect as it is known, and it generates heat or endothers depending on the direction of the current and provides heat or cold.

As shown in FIG. 8, the thermally conductive heat dissipation fins 442 are fixed to the thermoelectric elements 441 in plural, and are in thermal contact with the air to transfer heat or cool air to the air.

Accordingly, the air cooled / heated by the heat exchange member 430 can be discharged to the set temperature while being further cooled or heated by the heating member 440. [

Therefore, the fan coil unit 400 of the present invention can perform additional individual cooling / heating by the heating member 440 against the central cooling / heating by the heat exchange member 430.

In addition, the photocatalytic lamp 470 may be installed in the communication space 413 of the casing 410 as shown in FIG.

The photocatalyst lamp 470 is a member for providing an antibacterial and deodorizing effect through a photochemical reaction and is remotely controlled by a central server 800 or a control panel 700 to purify and discharge air.

The photocatalyst lamp 470 may include a base member 710, an ultraviolet lamp 720, a photocatalyst grill 730, and a photocatalyst guide 740, as shown in FIG.

The base member 710 is fixed to the communication space 413b while being fixed to the casing 410. [ The base member 710 may be provided with members for interrupting and controlling the power of the ultraviolet lamp 720, such as a ballast not shown.

The ultraviolet lamp 720 emits ultraviolet rays while being emitted from the base member 710.

Ultraviolet rays have germicidal power as it is known. Particularly, those having a wavelength of around 250 nm have a large sterilizing power, and 99% of Escherichia coli, Diphtheria, and Heterogeneous bacteria are sterilized by irradiating ultraviolet ray having a intensity of 100 μW per 1 cm 2 for 1 minute.

The type and detailed configuration of the ultraviolet lamp 720 are well known in the art to which the present invention pertains, and therefore, a detailed description thereof will be omitted.

The photocatalyst grill 730 is a member for decomposing harmful substances while reacting with the light of the ultraviolet lamp 720 by receiving the ultraviolet lamp 720 in a state in which the photocatalyst is coated.

Here, the kind of the photocatalyst is not limited, and any structure known in the art to which the present invention belongs can be adopted, for example, a titanium dioxide photocatalyst.

The titanium dioxide photocatalyst is an n-type semiconductor. When ultraviolet rays (400 nm) are received, an electron and an electron hole are formed to produce hydroxyalcic acid (-OH) and superoxide having strong oxidizing power. Hydroxy radicals and superoxide decompose organic compounds into water and carbon dioxide.

In this way, pollutants in the air are oxidized and decomposed into harmless water and carbon dioxide, and the organic compounds, which are contaminants in the water, are decomposed into water and carbon dioxide. Since bacteria are also organic compounds, they are oxidized and decomposed by the strong oxidizing action of the photocatalyst and sterilized.

The photocatalyst grille 730 is formed in a tubular shape as shown in FIGS. 9 and 19, and the photocatalyst is coated on the inner circumferential surface and the outer circumferential surface of the photocatalytic grill 730. The photocatalyst grill 730 is detachably coupled to the base member 710, And a plurality of through holes 731 are formed to transmit the light of the ultraviolet lamp 720 to the outside.

Here, the photocatalyst grille 730 may be screwed to the base member 710, or may be detachably coupled through a fixing protrusion (not shown) or a separate fixing member such as a fixing bolt.

The photocatalyst guide 740 is a component for increasing the contact time between the air introduced into the photocatalyst grille 730 and the photocatalyst.

The photocatalyst guide 740 may be constituted by a stone plate 741 as shown in Figs. 9 and 10, for example.

As shown in the figure, the stone plate 741 protrudes in an arc shape on the inner circumferential surface of the photocatalyst grille 730 and alternately protrudes along the longitudinal direction of the photocatalyst grille 730 in a symmetrical state, thereby bypassing the air.

That is, as the air introduced into the photocatalyst grille 730 moves in a zigzag manner by the alternate state stone plate 741, the contact time with the photocatalyst agent is increased, so that the harmful substances can be purified smoothly.

Alternatively, the photocatalyst guide 740 may be a screw guide plate projecting in the form of a screw along the inner circumferential surface of the photocatalyst grille 730 to guide the air in a rotated state.

In addition, the photocatalyst lamp 470 of the present invention may further include a reflection plate 750 as shown in FIG.

The reflector 750 reflects the light of the ultraviolet lamp 720 transmitted through the transmission hole 731 of the photocatalyst grille 730 and thereby generates a component for guiding the reaction of the photocatalyst coated on the outer circumferential surface of the photocatalyst grille 730 to be.

Here, since the ultraviolet lamp 720 is accommodated in the photocatalyst grille 730, the ultraviolet lamp 720 directly irradiates light only to the inner circumferential surface of the photocatalytic grille 730, and it is impossible to directly irradiate light to the outer circumferential surface.

10, the reflection plate 750 reflects the light of the ultraviolet lamp 720 from one side of the photocatalyst grille 730 and directly irradiates the outer surface of the photocatalyst grille 730 to the photocatalyst grille 730, The photocatalyst coated on the outer circumferential surface can decompose harmful substances in the air while reacting smoothly with the light of the ultraviolet lamp 720 reflected by the reflection plate 750.

The reflection plate 650 may be made of, for example, a metal mirror having durability, and may be fixed to the base member 710 or attached to the casing 410 as shown in Fig. 13, Or on both sides.

As described above, according to the remote control system of the fan coil unit using the wireless LAN of the present invention, the fan coil units 400 are controlled by the central server 800 or the control panel 700 through the wireless connection AP 600, As a result, it is possible to construct a system without any damage to aesthetics as well as reduction of construction costs and time, and remote control is performed based on a universal wireless network protocol, so that low-cost commercial devices can be utilized.

Since the central server 800 directly controls the fan coil units 400 and controls the operation of the control panel 700, it is possible to control the fan coil units 400 of the entire building at the center, Such as room temperature limit, by allowing or inhibiting the operation of the controller 700. < RTI ID = 0.0 >

In addition, since the radio access APs 600 in the separated areas are connected by the directional antenna 900, the fan coils 400 installed in another building can be controlled through a single central server 800 have.

Since the damper 415 provided at the first inlet 411a and the second inlet 411b of the fan coil unit 400 is opened and closed by the control panel 700 and the central server 800 and uses outdoor air, And the energy due to heating can be saved.
