Although the intake module 100 is described as an example in the above-described embodiment, it is obvious that the exhaust module 400 can be replaced with an outlet panel (not shown) having the same configuration as the inlet panel 3A.

The assembling process of the intake module 100 is not limited to the assembling of the intake module 100 but the assembling process of the mixing module 200 and the heat exchange module 300 may be simplified, And the exhaust module 400 of the present invention.

In the air handling unit 1 according to the preferred embodiment of the present invention, the process of assembling in the module unit as described above is performed in a manufacturing factory where the air handling unit is installed and dried, , To a building where the actual air handling unit is installed and dried in a place assembled in module units using a short distance transportation means such as a forklift (M) or a long distance transportation means such as a vans or the like, And can be carried in module units from the outside of the building to the internal machine room of the building where the air handling unit is installed. As described above, in the preferred embodiment of the present invention, the intake module 100, the mixing module 200, the heat exchange module 300, and the exhaust module 400, which are provided to form one complete air conditioning cycle, (1) are assembled and transported in units of modules from the outside of a building to be installed and dried, it is possible to satisfy both the ease of transportation, the prevention of omission of parts and the convenience of assembly.

However, in a preferred embodiment of the present invention, the intake module 100, the mixing module 200, the heat exchange module 300, and the exhaust module 400 are not necessarily assembled in one module unit, It is natural that at least two modules among the modules 100-400 may be individually assembled in units of modules, and then the two modules may be transported in a combined state. At this time, it is natural that the two modules should be coupled between adjacent modules so that a flow path of the air conditioning air for forming the air conditioning cycle is formed naturally.

9A to 9C are an exploded perspective view and a partially enlarged perspective view showing the connection of the case panel to the middle frame of the module frame, FIG. 10 is a sectional view taken along line AA in FIG. 9A, Sectional view of an example of various sealing portions between the corner frame and the case panel in the middle frame.

7A to 7F is merely an illustrative example. Specifically, the assembly of a plurality of module frames 20 constituting a module and a plurality of case panels 30 is shown in Figs. 9A to 9C. The method as shown in FIG. 9C may be adopted.

More specifically, a pair of case panels 30 are provided on one side and the other side in the horizontal direction of the middle frame 20B across the middle portion of the lower cover 30A among the case panels 30 forming the bottom surface of the module, A pair of sliding ribs 21 'and 21' 'inserted into the sliding rail grooves 31 formed in the rim portion of the case panel 30 may be formed on one side and the other side of the middle frame 20B .

Here, the case of the lower cover 30A has been described, but it goes without saying that the same can be applied to the case where the middle frame 20B is provided in the side cover 30B or the upper cover 30C.

Another example of a method of assembling using the module frame 20, the case panel 30 and the connecting member 40 having the above-described structure will be briefly described below.

First, as shown in Figs. 9A to 9C, a plurality of module frames 20 and a connecting member 40 are assembled to form the framework of the rim of the lower cover 30A. Here, the plurality of module frames 20 can be assembled into a simple rectangular shape using only the corner frame 20A and the corner connector 40A, but in some cases, the middle frame 20B and the middle connector 40B So that the skeleton of the rectangular shape is divided into two parts. Particularly, in a preferred embodiment of the present invention, the overall rigidity can be compensated by dividing the relatively long corner frame 20A by two members using the middle frame 20B.

The plurality of module frame 20 skeleton described above is formed by sliding the sliding rails 31 formed on the rim of the lower cover 30A and the sliding ribs 21 ' 7A to 7F so that one of the corner frames 20A is not provided to be opened so that the lower cover 30A The sliding ribs 21 'and 21' 'may be inserted into the sliding rail grooves 31 to slide the sliding ribs 21' and 21 '' in the case panel 30, as shown in FIGS. 9A to 9C, It is natural that the sliding ribs 21 'and 21 "of the module frame 20 are slidingly coupled to the formed sliding rail grooves 31 so as to be inserted.

The air handling unit 1 according to the preferred embodiment of the present invention includes a combination of the above-described two types of sliding engagements, and it is possible to improve assembling performance according to the assembling environment of the assembling site and the tendency of the co- It provides a variety of assemblies to choose the best way to be.

Conventionally, in installing an air handling unit, which is a relatively large structure installed inside a building, it is necessary to fasten a number of screws between the frame and the case panel in order to firmly install the frame that forms the entire frame. Such screw tightening means an increase in the number of assemblies for the engagement of the individual screws, and the overall rigidity is lowered due to the clearance of the screw engagement portion according to the change in the air pressure inside the air handling unit during operation.

A preferred embodiment of the air handling unit 1 according to the present invention is characterized in that aside from the screw joining process for engagement between the plurality of module frames 20 and the connecting member 40, The sliding engagement between the frame 20 and the case panel 30 in which the screw joining process is completely eliminated can significantly reduce the number of individual screw assembling processes and solve the problem of weakening the rigidity of the screw fastening portion.

On the other hand, in the air handling unit, it is very important to prevent leakage between the inside and the outside where the air conditioning air flows. This is because, when the air-conditioning air is leaked, the pressure inside the air handling decreases, resulting in a pressure loss, resulting in deterioration of the overall air-conditioning performance.

Conventionally, a plurality of frames are combined through a screw (S) connection and a welding connection method to form an entire skeleton, and a case panel is fitted to an opening corresponding to a shape of a plurality of case panels, There was an inconvenience that the sealing work had to be separately performed. More specifically, conventionally, for the primary sealing, a case panel is wrapped around the rim of the case panel using an insulating tape before the connection to the opening of the case panel, and for the secondary sealing, A separate sealing material such as silicone was applied.

The sealing pads 47 are brought into close contact with each other when the module frames 20 and the corner connectors 40A are engaged with each other to block the gap between the module frames 20 and the corner connectors 40A, .

The ceiling pad 47 is formed with an end through hole 48A through which the insertion ends 41A, 42A and 43A of the corner connector 40A penetrate, so that the insertion ends 41A, 42A and 43A A through hole 48 having the same shape as the hollow portion 23 formed at the end of the module frame 20 is formed so as to be able to completely shield between the module frame 20 and the corner connector 40A It is also possible that the end of the module frame 20 and the corner connector 40A are not directly contacted with each other.

When the module frame 20 and the corner connector 40A are made of a metal having high thermal conductivity, the sealing pad 47 also functions to prevent energy leakage by lowering the high thermal conductivity between the metal and the metal.

The sealing pads 47 can be interposed between the middle connector 40B and the middle frame 20B or between the middle connector 40B and the corner frame 20A as well as the corner connector 40A.

The fan box 60 includes a plurality of box frames 120 disposed inside the centrifugal chamber C2 and spaced apart from one side of the partition wall 107 to form an outer skeleton and a plurality of box frames 120 To protect the rotation of the centrifugal fan 140 while forming an outer surface.

Here, the partition wall 107 and the fan box 60 may be connected such that air sucked through the communication port 107A flows to the centrifugal fan 140. [ That is, the fan box 60 is configured such that the air in the suction chamber C1 passes entirely through the centrifugal fan 140 provided in the fan box 60 of the centrifugal chamber C2, 107A. A detailed description thereof will be given later.

In the fan box 60, an external skeleton of a predetermined shape is formed by a box frame connector 125 connecting two or more box frames 120 at corner portions. More preferably, the fan box 60 is formed in a rectangular parallelepiped shape having a predetermined installation space such that a centrifugal fan 140 and a fan motor are installed therein. The box frame connector 125 has rectangular parallelepiped- So that the three box frames 120 can be vertically connected to each other.

The connection ring 131 may be formed by bending a part of the plurality of iron wires roundly, or may be manufactured as a separate member and attached to the rim of the safety net 130.

The connection ring 131 mediates installation of the safety net 130 on the box frame 120 by fastening the screw S to the screw hole 123 of the box frame 120.

After the safety net 130 is installed in the box frame 120, a corner-shaped support member 180 for supporting the corner portion of the fan box 60 can be engaged.

As shown in Fig. 17, the fan modules 101 and 401 having the above-described configuration are provided with a lower cover 30A arranged on the upper side of the base 10 and a lower cover 30A arranged parallel to the upper side of the lower cover 30A, And is installed on the upper side of the coupled pair of fan module brackets 110.

 The fan module bracket 110 is provided to prevent the fan modules 101 and 401 from being installed directly on the upper side of the lower cover 30A. And is installed through the vibration absorbing block 105 interposed between the fan box connection end 128 of the corresponding box frame connector 125 and the fan module bracket 110 to operate the centrifugal fan 140 of the fan modules 101, Can be prevented from being directly transmitted to the lower cover 30A.

FIG. 24 is a perspective view showing a centrifugal fan in the configuration of the fan module, and FIG. 25 is a cross-sectional view showing a vertical section of the blade in the configuration of the centrifugal fan in FIG.

Generally, the centrifugal fan 140 is a kind of fan that accelerates the air introduced in the axial direction through the fan shroud 1120 to form a centrifugal force in the radial direction between the blades 1130 to discharge the centrifugal fan. The performance of the centrifugal fan 140 is affected by various shape factors as well as friction loss, impact loss, and the like.

In a preferred embodiment of the air handling unit 1 according to the present invention, the centrifugal fan 140 constituting the fan modules 101 and 401 has a concave section on the upper side of the blade 1130, And a convex section in a direction away from the rotation axis O is formed in the lower part to enhance the flow in the lower part of the blade 1130 as well as to reduce the noise by uniformizing the flow between the upper and lower parts of the blade 1130, , And a centrifugal fan (140) having a greatly improved performance of the fan in the same size or volume as the conventional one.

24, the centrifugal fan 140 includes a pair of main plates 1110 rotated around the rotation axis O and a fan 1110 having a suction hole 1121 through which air is sucked A plurality of blades arranged along the circumferential direction between the shroud 1120 and the pair of main plates 1110 and the fan shroud 1120 and air sucked through the suction holes 1121 flow from the front end to the rear end 1130).

Here, as shown in FIG. 25, the blades 1130 are arranged in the order of the first end face S (L1), the second end face S (L1), and the second end face 1120 in this order from the fan shroud 1120 side to the main plate 1110 side on the layers The front end of the first end face S (L1) is defined as the fourth end face S (L1) when the end face S (L2), the third end face S (L3) and the fourth end face S The rear end of the first end face S (L1) is closer to the rotation axis O than the rear end of the fourth end face S (L4), and the rear end of each end face The rear end of the second end face S (L2) may be farthest from the rotation axis O and the rear end of the third end face S (L3) may be formed closest to the rotation axis O.

Such blades 1130 may have a 3D shape, as shown in Fig. Here, the 3D-shaped blade 1130 refers to a blade 1130 in which the cross-sections of the blade 1130 on predetermined layers having predetermined planes orthogonal to the rotation axis O are formed in a predetermined projection plane , It is defined that two or more of the lines connecting the front end (FE) and the rear end (RE) of each cross section on the projection plane are not located on the line.

According to the above-described 3D-shaped blades 1130, it has been confirmed through experiments that the static pressure is increased and the efficiency is improved as compared with the conventional centrifugal fan 140, assuming the same air volume. Particularly, the efficiency of the centrifugal fan 140 reaches approximately 82%, which is remarkably improved compared with the conventional one, which is approximately 70%. Such improvement of the fan performance enables low-speed driving to generate the same air volume, The fact that the drive is possible means that the drive of the fan motor 150 with a small load at the same high-speed drive can sufficiently drive a preferred embodiment of the air handling unit 1 according to the present invention.

In a preferred embodiment of the air handling unit 1 according to the present invention, the fan modules 101 and 401 can be installed in the centrifugal chamber C2 in a single step, and correspond to the target demand load of the continuously variable air- A plurality of fan modules 101 and 401 may be arranged in parallel or stacked in the centrifugal chamber C2. This is because the volume of the fan motor 150 is reduced and the volume of the 3D-shaped centrifugal fan 140 is reduced, so that there is no need to construct a fan module 101, 401 of a large size inconvenient for installation and transportation.

In consideration of the unique 3D shape of the centrifugal fan 140 having only one preferred embodiment of the air handling unit 1 according to the present invention, the assembly of the unique modularized fan modules 101 and 401 The structure will be described in detail below.

18 and 19, the fan modules 101 and 401 suck air in the suction chamber C1 into a pair of the main plates 1110 arranged vertically and spaced apart in the direction of the rotation axis, A centrifugal fan 140 for radially discharging the centrifugal chamber C2 to the centrifugal chamber C2 through a plurality of blades 1130 connecting the main plates 1110 to the centrifugal fan 140, A fan box 60 having an installation space in which a centrifugal fan 140 and a fan motor 150 are installed and a fan motor 60 disposed inside the fan box 60, And a guide unit 190 that forms an inflow path through which the air of the suction chamber C1 flows into the pair of the main plates 1110 of the fan 140. [

Here, the centrifugal fan 140 employs the above-described 3D centrifugal fan 140, which requires a relatively small size or a small volume to generate the same air volume. The centrifugal fan 140 is rotatably driven in the fan box 60 constituting the fan modules 101 and 401 to suck air from the suction chamber C1 into the centrifugal chamber C2, Thereby forming a fluid force.

The fan modules 101 and 401 are installed in the fan box 60 so that the fan motor 150 having a vertical height smaller than the vertical height of the centrifugal fan 140 is installed in the fan box 60, 140 may include a motor bracket 170 that mediates installation inside the fan box 60 such that the rotation center of the fan bracket 140 is coaxial with a straight line in the horizontal direction.

19, a pair of the motor brackets 170 are arranged so as to be spaced apart from each other inside the fan box 60. The fan modules 101 and 401 are connected to the pair of motor brackets 170 at both ends thereof, And a support plate 160 connected to the fan motor 150 to support the fan motor 150 from below.

The motor bracket 170 is horizontally long and coplanar with the air on both sides adjacent to the surface where air is sucked into the fan box 60 and the support plate 160 is mounted on the upper surface of the pair of motor brackets 170 So that the lower surfaces of both the left and right ends are supported.

The rotation axis 150C of the fan motor 150 may be firmly coupled to the upper portion of the support plate 160 so as to be coaxial with the rotation center of the centrifugal fan 140 in a straight line. The support plate 160 should be designed to support not only the fan motor 150 but also the load including the weight of the centrifugal fan 140 coaxially connected to the fan motor 150. [

In the safety net 130 adjacent to the fan motor 150, a motor inserting hole 135 is formed to penetrate the fan motor 150 so that the fan motor 150 can be installed easily. . This is to provide a convenience of repairing the fan motor 150 when the fan motor 150 is to be repaired or replaced, without having to disconnect the safety net 130. However, it should be noted that the motor-inserting hole 135 is not necessarily formed in the safety net 130.

The guide unit 190 includes a bell mouth 193 connected to the fan shroud 1120 formed on the suction side of the centrifugal fan 140 and guiding air into the pair of the main plates 1110, And a fan shield 191 connected to the edge of the fan box 60 and having a mouth hole 191A communicating with the bell mouth 193.

The fan shroud 1120 is integrally formed with the centrifugal fan 140 and has a circular suction hole 1121 formed on the outer side of the main plate 1110 of the pair of the main plates 1110, And may be formed to protrude toward the suction portion.

The bell mouth 193 is not directly connected to the end of the fan shroud 1120 protruding toward the suction side for rotation of the centrifugal fan 140 but the air in the suction chamber C1 is directed toward the centrifugal fan 140 side It plays a role of inducing naturally. The bell mouth 193 is fixed to the above-described fan shield 191, and can be fixed so as to communicate with the mouse hole 191A.

The fan shield 191 is installed in the outer surface of the fan box 60 in place of the safety net 130 on the side where the safety net 130 is not provided to protect the centrifugal fan 140, And also serves to prevent the intake air from leaking from the suction chamber C1 to the space of the centrifugal chamber C2 other than the fan box 60. [

The guide unit 190 may include an air guide tunnel unit for connecting the communication hole 107A of the partition wall 107 and the fan box 60. [ The air guide tunnel portion is configured such that the spaced space between the partition wall 107 and the fan modules 101 and 401 (particularly, the fan shield 191) is connected to the centrifugal fan 140 (not shown) through the communication port 107A of the partition wall 107 And is configured to simultaneously absorb vibrations transmitted from the centrifugal fan 140 to the partition wall 107. In addition,

According to the preferred embodiment of the air handling unit 1 according to the present invention configured as described above, the target load condition of the space to be air-conditioned in the building in which the air handling unit 1 is installed may differ from building to building, 23, the number of the fan modules 101, 401 disposed in the intake module 100 and the exhaust module 400 may be determined based on the target load amount condition and the air conditioning design conditions required by the air conditioner designer, Fan modules I, II, III, IV may be provided. 23 shows an embodiment in which a plurality of fan boxes 60 are stacked or arranged side by side by the fan box connection end 128. However, the present invention is not limited to this, and a larger number of fan boxes 60 60 of the module frame 20 can be stacked or arranged side by side and the fan box 60 can not be provided according to the target load condition by the limited space of the centrifugal chamber C2, 20B) to increase the volume of the entire module.

Conventionally, a large-capacity centrifugal fan and a relatively large fan motor for driving the centrifugal fan are provided. Since the fan motor has a large weight, a stable fan motor is installed and a power transmission system for stably providing rotational power from the fan motor Belt and pulley drive system. In order to compensate for the power loss caused by adopting such belt and pulley drive system, the air volume generated from the centrifugal fan through the fan housing surrounding the centrifugal fan is concentratedly discharged through the predetermined discharge port The airflow induction method was adopted. Such a conventional centrifugal fan and fan motor installation and driving method is based on the problem that the overall fan efficiency such as the weight and size of the unit centrifugal fan can not be ensured. In contrast to the motor rotation-axis direct drive type centrifugal fan and fan motor A fan housing is required because a constant static pressure due to the centrifugal fan can not be secured and a fan housing is required. In the fan housing, a bidirectional suction and a unidirectional suction can be applied according to the suction structure of the air. The internal design of the fan housing is complicated, and in the case of the bidirectional suction type, the airflow loss due to the coupling portion of the belt and the pulley is expected, and the fan efficiency is greatly reduced.

In the preferred embodiment of the air handling unit 1 according to the present invention, by adopting the 3D-shaped centrifugal fan 140, the fan motor 150 having a large weight required for driving the conventional large-capacity centrifugal fan 140 It is possible to reduce the size of the fan modules 101 and 401 and reduce the size of the entire fan modules 101 and 401 so as to reduce the size of the fan modules 101 and 401. [ According to the target load condition, if necessary, a plurality of the fan modules 101 and 401 can be installed and operated variably, thereby creating an advantage that a more comfortable air conditioning environment can be created.
