A large-capacity explosion-proof air conditioning system for extreme cold according to a preferred embodiment of the present invention is composed of a housing 100, a louver 200, a preheater 300, a damper 400, and an intake fan 500, as shown in FIG. , Each configuration has technical characteristics and will be described below.

First, the housing 100 is examined.

The housing 100 may serve to support the entire configuration to be provided therein, or may serve to protect other components from external impacts.

In general, the housing 100 is formed of a hollow structure, and may be collectively referred to as providing a space into which the structure is inserted.

The housing 100 of the present invention may be a passage through which air introduced from the outside is supplied to the inside by being installed such that one side is located outside and the other side is located inside.

An outside air inlet 110 may be provided on one side of the housing 100 located outside, and the outside air inlet 110 may be configured in a shape such as a nozzle, or may be configured in a form in which the housing 100 is opened.

In general, the cross-sectional area of the outdoor air inlet 110 may be configured to have the same cross-sectional area as the cross-sectional area of the housing 100 to facilitate the inflow of outside air.

An outside air outlet 130 may be provided on the other side where the housing 100 is located. Like the outside air inlet 110, the outside air outlet 130 may be configured in various forms, but the cross-sectional area of the housing 100 It may be desirable to be configured in the same form as.

Due to the above-described morphological features of the outside air inlet 110 and the outside air outlet 130, the housing 100 may be formed as a cylindrical or box-shaped structure in which both sides are open when viewed as a whole, but ease of installation and transportation Considering it may be desirable to be configured in a box-like form.

The housing 100 may be made of any material, but it may be made of a metal material that is generally used in ships or plants. It can be configured as a sealed type so that it does not leak.

Additionally, it may be formed as a set of detachable unit structures to facilitate access to the interior of the housing 100 during maintenance, and a handle may be attached for easy separation and coupling operation.

In addition, it may have a strength that is not destroyed even by an explosion pressure that may occur during an explosion, and it may be desirable to form a multilayer structure in which a plurality of metal plates are overlapped.

Next, look at the louver 200.

A plurality of louvers 200 may be installed on the side of the outside air inlet 110 of the housing 100 to prevent moisture or foreign substances contained in the outside air from entering through a physical barrier wall.

In general, a louver is a general term for preventing light or water from being moved from one side to the other, and may be generally composed of a flat blade.

The blade of the louver 200 of the present invention may have a characteristic structure in order to effectively collect moisture or foreign matter from the outside air.

The blade of the louver 200 may be composed of a main body 210 and a screen 230.

The main body 210 is a structure that maintains the structural strength of the entire blend of the louver 200 and may be configured in a bent shape.

The main body 210 may be formed to be bent to have an angle, or may be formed in an arc shape, but it may be desirable to be formed to have an angle in consideration of convenience in manufacturing and ease of installation.

The main body 210 allows the inflow path of the outside air flowing into the outside air inlet 110 to be bypassed, so that the outside air comes into contact with the main body 210 so that moisture or foreign substances of the outside air are collected in the main body 210. .

In detail, the blades of the louver 200 are bent and installed so that the protruding surface is in contact with the inflow path of the outside air, so that the inflow path is bypassed by colliding with the bent surface of the outside air.

The main body 210 may be provided with a plurality of screens 230 through which moisture or foreign matter colliding with the main body 210 is collected.

The screen 230 may have one end attached to the outer surface of the main body 210 and the other end formed as a free end, and the free end may be oriented toward the incoming outside air.

Since the shape of the main body 210 is bent, and the incoming outside air is bypassed by the main body 210, the screen 230 may have different installed shapes depending on the position attached to the main body 210. have.

For ease of explanation, the screen 230 is formed extending from the outer surface of the main body 210 toward the center of the flow path of the outside air into which the free end is formed so that a space for collecting moisture or foreign matter contained in the incoming outdoor air is formed. Can be

The louver 200 may be preferably installed so that the bent direction of the main body 210 is positioned on a horizontal plane so that the collected moisture or foreign matter can fall freely.

The louver 200 is configured to first contact with the outside air, and the present invention may increase the temperature of the outside air by the louver 200.

A method of attaching a planar heating element to the blade to the louver 200 or heating the inside of the louver 200 blade by a separate heat source may be used, but the present invention uses the fluid circulated in the preheater 300 to be described later. You can let it heat up.

Additionally, due to the above-described characteristics, a role of preventing freezing of the louver 200 may be implemented.

Preferably, the louver 200 has a tubular flow path formed inside the main body 210 so that fluid can be circulated, and a plurality of blades may communicate with each other.

A first supply port 211 may be formed in the louver 200 to which the fluid discharged from the preheater 300 is initially supplied, and a first discharge port 213 may be formed in the louver 200 finally discharged.

The circulation of the fluid according to the communication between the louver 200 and the preheater 300 will be described later.

Next, the preheater 300 is looked at.

A pre-heater 300 is an equipment installed on the outside air inlet 110 side of the housing 100 and installed inside the housing 100 relative to the louver 200. It may serve to increase the temperature of the air before being supplied to the inside, and it may be desirable to minimize the length of the circulation line L2 to be described later by being installed so as to contact the preheater 300 and the louver 200.

Since the preheater 300 performs heat exchange by contact with outside air sucked into the housing 100 through the louver 200, the preheater 300 may be formed in a structure in which a contact surface is maximized for efficient heat exchange.

Specifically. The heated fluid, which is a heat source, passes through a flow path formed in a tubular shape in the center of the preheater 300, and a radiating means such as a radiating fin is formed in a radial or airfoil shape to a core structure 310 on the outer surface of the flow path. By being formed, heat of the heated fluid is transferred to the heat dissipating means, so that heat exchange efficiency with air can be maximized.

The preheater 300 may be configured in a state in which a plurality of core structures 310 are overlapped. Each core structure 310 communicates with each other so that the heated fluid may sequentially circulate inside the core structure 310.

A second supply port 311 may be formed in the core structure 310 to which the heated fluid is initially supplied to the preheater 300, and a second discharge port 313 may be formed in the core structure 310 that is finally discharged.

The fluid penetrating the interior of the preheater 300 may be any fluid that can flow by a pump or the like, but it may be desirable to use a fluid having a relatively high thermal conductivity but low explosive potential to secure stability.

In the present invention, the circulation line (L2) is provided so that the louver 200 and the preheater 300 communicate with each other, so that the fluid discharged from the preheater 300 is supplied to the louver 200 can be formed. have.

Specifically, the circulation line (L2) is a tubular flow line, one end is coupled to the second outlet 313 of the preheater 300 and the other end is coupled to the first supply port 211 of the louver 200, The fluid, which has been heat-exchanged once by the heater 300, is supplied to the louver 200 so that the heat exchange is performed again.

A flow control valve V, which can be manually or automatically adjusted by a sensor, is installed in the circulation line L2 to control the flow rate of the fluid supplied to the louver 200, thereby controlling the temperature in detail.

In terms of fluid, heat exchange is performed in the preheater 300 first, and then heat exchange is performed again in the louver 200, but from the viewpoint of incoming external air, heat exchange is performed first in the louver 200, and then the preheater 300. In the form of heat exchange again.

Looking at the overall configuration in which the flow path is formed, the supply line L1 is coupled to the second supply port 311 of the preheater 300, and the second discharge port 313 and the louver 200 of the preheater 300 are A circulation line (L2) is coupled between the first supply ports (211), and a discharge line (L3) is supplied to the first discharge port (213) of the louver (200), and as a result, the heated fluid is transferred to the preheater (300). It may be supplied as a form discharged from the louver 200.

A process in which the temperature of the outside air and the fluid is changed by heat exchange with the flow path is examined by assuming the temperature of the extreme cold to which the present invention is applied and the temperature of the heated fluid.

A fluid of about 190° C. is supplied to the supply line L1, and the fluid is heat-exchanged with outside air in the preheater 300 to become about 150° C., and is supplied to the louver 200 through the circulation line L2. In 200), the fluid of about 120°C is discharged to the discharge line L3 by heat exchange with outside air.

The fluid discharged to the discharge line (L3) is heated to about 190°C again, and then supplied to the supply line (L1) to repeat the above process. In this process, the housing 100 is heated to about -52°C. The outside air introduced into the outside air inlet 110 of the is heated to about 5°C and discharged to the outside air outlet 130 of the housing 100.

Next, the damper 400 is looked at.

The damper 400 may collectively refer to a configuration capable of functioning as a buffer for controlling the flow rate of incoming outdoor air.

The damper 400 may be installed at the outside air outlet 130, and a plurality of damper blades 410 rotatable around the center are arranged, and the flow rate is changed by changing the cross-sectional area of the surface where the outside air is introduced by rotation. Can be adjusted.

The flow rate is adjusted by changing the cross-sectional area by the rotating damper blade 410, but each damper blade 410 may be manufactured by strictly applying a tolerance of dimensions so that it can be sealed when the inflow of outside air is not made. ,

For convenience in use, a plurality of damper blades 410 may be combined by a link structure to be configured to rotate at the same time, but may be performed by manual operation or automatically rotated by a separate flow sensor and control device. I can.

Specifically, a damper plate 430 having an arc-shaped groove formed on one side of the damper 400 is installed, and a lever 450 capable of applying opening and closing of the damper blade 410 may be coupled to the groove. have.

A link bar 470 connecting each damper blade 410 to rotate at the same time may be installed on the side where the damper plate 430 is installed, and the lever 450 and the link bar 470 are the damper plate 430 The link can be coupled through the intervening, and the rotational motion of the lever 450 is converted into an up-and-down linear motion of the link bar 470, and the up-and-down linear motion of the link bar 470 is a rotational motion of the damper blade 410. You can have it converted again.

According to this link coupling structure, the lever 450 rotates in an arc along the groove of the damper plate 430, and when the lever 450 reaches one end of the groove, the vertical linear motion of the link bar 470 is available. The range is moved to the maximum value, and the damper blade 410 is completely rotated, and as a result, the damper 400 may have a completely open shape.

When the lever 450 is rotated in the opposite direction to reach the other end of the groove, the vertical linear motion of the link bar 470 moves to the minimum available range, and the damper blade 410 rotates. Through the process of being completely sealed, the flow rate of the outside air can be adjusted.

Finally, the intake fan 500 is looked at.

The intake fan 500 is installed inside the housing 100 and may be installed between the preheater 300 and the damper 400.

The intake fan 500 may include a case 510, an impeller 530, and a control panel 550.

The case 510 serves as a support on which the impeller 530 and the control panel panel 550 may be provided, but considering that the impeller 530 rotates, both sides are cylindrical with open circular surfaces, but the hollow It can be (中孔).

The case 510 may cause an explosion by generating a spark when in contact with the impeller 530 to be described later, so that the rotation radius and the clearance gap of the impeller 530 may have a diameter of a sufficient degree so that there is no absolute contact. .

Additionally, in general, the case 510 may be made of a metal material, but may be made of a non-ferrous metal, aluminum, magnesium alloy, or austenitic stainless steel to remove static electricity and prevent sparks.

The impeller 530 is installed to rotate inside the case 510 and may serve to suck outside air into the inside by rotation.

The impeller 530 may be generally configured in a shape having a blade to have excellent suction performance, and as in the case 510 described above, a non-ferrous metal, aluminum, magnesium alloy, or austenitic stainless steel may be used to remove static electricity and prevent sparks. Can be made.

The control panel panel 550 is attached and installed outside the case 510 and may serve to supply an electric signal or power for controlling the rotation of the impeller 530.

Since the inside of the control panel panel 550 is configured with a circuit and current is inevitably present, it is necessary to provide a separate explosion-proof function because the possibility of generating sparks is the highest among the configurations of the intake fan 500.

In general, the control panel panel 550 may be configured in a box shape to prevent impact from external force, but the present invention constitutes a sealed box but is configured in a sealed type so that explosion-proof performance is provided so that internal sparks do not leak out. In addition, it has a strength enough not to be destroyed even by an explosion pressure that may occur during an explosion, and may preferably be formed in a multilayer structure in which a plurality of metal plates are overlapped.

Additionally, due to the explosion-proof performance applied to the housing 100 and the intake fan 500 described above, it may be possible to install a large-capacity air conditioning system.

Specifically, it was common to apply an air conditioning system with an output of about 30 to 50 kW, but it is possible to apply an air conditioning system with an output of about 500 kW because it has an explosion-proof performance to reduce the possibility of explosion and minimize damage during explosion. I can.

The above-described embodiments are merely exemplary, and other embodiments variously modified therefrom are possible for those of ordinary skill in the art.
