air Compression pumps

22a and 22b supplied to the air chamber 10 through LI1, LI2 and LI3, a refrigeration cycle 16 in which an evaporator 18 or a condenser is installed in the air chamber 10, and air The first regulator 24b for adjusting the air pressure supplied through the branch lines LD1 to LDn branched from the supply line LS1, and the valve 26 for controlling the flow of air through the branch lines LD1 to LDn. And a controller 40 receiving the open / close signal of the valve 26 to control the driving of the

compression pumps

22a and 22b and the refrigeration cycle 16.

In addition, the second regulator 24a may be further provided to adjust the compressed air supply pressure in the air chamber 10 to be supplied to the air supply line LS1.

First, the air chamber 10 constituting the present invention will be described in more detail. As shown in FIGS. 1 and 2, the internal volume according to the design is already partitioned, and an air inflow line LI1 is formed at one side. , LI2, LI3) is connected in communication, the air supply line (LS1) is connected to the other side to form a configuration in communication.

In addition, the air chamber 10 connects an evaporator or a condenser (hereinafter, referred to as an 'evaporator / condenser') part of the configuration constituting the refrigeration cycle 16 described above to cool or heat the air contained therein. I'm trying to.

The air chamber 10 has a configuration in which a first pressure sensor 12a for measuring the degree of air pressure contained therein and a first temperature sensor 14a for measuring the temperature of the air contained therein are provided.

Here, as described above, the internal volume of the air chamber 10 is, as will be described later, of the compressed air that can be supplied to the worker through the branch line (LD1 ~ LDn) branched from the air supply line (LS1) The design is based on the maximum supply.

On the other hand, the compression pump (22a, 22b) constituting the present invention is installed on the air inlet line (LI1, LI2, LI3) leading from the outside to the air chamber 10 to compress the air sucked from the outside, and thus compressed One compressed air is supplied into the air chamber 10.

At this time, the compressed air supply amount of the

compression pump

22a, 22b, as in the volume design inside the air chamber 10 described above, the maximum supply amount of the compressed air that can be supplied to the operator through the branch lines (LD1 ~ LDn) It is preferable to apply on the basis.

Therefore, if the compression pumps 22a and 22b sufficiently correspond to the maximum supply amount of compressed air supplied to the operator, only one

compression pump

22a or 22b may be installed in the air chamber 10, but two or more compression pumps may be provided. It can also be made by installing a number.

In this case, when the number of installation of the compression pumps 22a and 22b is more than two, the number of the compression pumps 22a and 22b is limited to use only in response to the change in the compressed air supply amount used by the workers. By stopping unnecessary driving of the compression pumps 22a and 22b, it is possible to expect an effect of reducing unnecessary energy consumption due to the operation of the compression pump of the near capacity.

On the other hand, the refrigeration cycle 16 constituting the present invention, the compressor, condenser, expansion valve, the evaporator constituting the general refrigeration cycle 16, only the evaporator 18 or the condenser portion installed in the air chamber 10 inside the air chamber 10 (10) Heat exchange with the compressed air inside.

Here, the evaporator / condenser 18 applied in the present invention acts as an evaporator when the refrigerant flow in the refrigerating cycle 16 is in one direction (direction for cooling the compressed air in the air chamber), and reverses the flow of the refrigerant. It acts as a condenser in the direction (direction for heating the compressed air in the air chamber).

The application of the technical configuration of the refrigeration cycle 16 such that the evaporator / condenser 18 can selectively apply the function as the evaporator or the function as the condenser is well known in the related art and thus detailed description thereof is omitted. Let's do it.

In addition, the second regulator 24a which adjusts and supplies the compressed air flowing from the air chamber 10 to the air supply line LS1 to the preset air pressure in the air supply line LS1 adjacent to the air chamber 10. ) Is made.

Here, the installation of the second regulator 24a is not necessarily required, and the pressure inside the air chamber 10 and the air supply line LS1 are equally formed, and the first regulator 24b is described later. It would be satisfactory if the pressure could be supplied by lowering the air pressure to the branch lines LD1 to LDn.

In addition, it is because the air supply line 24a may be made of a configuration in which one or more air chambers 10 are connected.

Each of the branch lines LD1 to LDn branched from the air supply line LS1 is supplied by adjusting the compressed air flowing from the air supply line LS1 to the branch lines LD1 to LDn at a predetermined air pressure. Installation of the first regulator 24b is made.

Here, the above-described second regulator 24a and the first regulator 24b form different adjustment values of the air pressure passing through the installation position.

To present a preferred example, when the compression pump (22a, 22b) under the control of the controller 40 is assumed to be driven so that the air pressure in the air chamber 10 is in a stepped range within the range of 5 ~ 10bar, The second regulator 24a causes the air pressure traveling from the air chamber 10 to the air supply line LS1 to be at the selected air pressure adjustment value within a range of more than 3 bar and less than 5 bar.

In addition, the first regulator 24b allows the air pressure traveling from the air supply line LS1 to the branch lines LD1 to LDn to be at the selected air pressure adjustment value within a range of more than 1 bar and 3 bar or less.

Here, the above-mentioned first and

second regulators

24a and 24b and the third regulator 24c to be described later may be manual regulators for allowing compressed air to pass through the supply air pressure level set by the operator's manual operation, or as described above. It may be an electronically controlled regulator having a solenoid valve to control the supply air pressure of the compressed air by the control of one controller (40).

In addition, it is desirable to design the internal volume of each component in addition to the pressure conditions of the above components.

For example, the volume of the air supply line LS1 is formed by adding up the volumes of all the branch lines LD1 to LDn branched from the air supply line LS1, and the air chamber 10 supplies the air. It is preferable to form more than the volume of the line LS1.

In addition, the compressed air output of the compression pumps 22a and 22b described above is preferably above the maximum supply capacity that can be supplied to all the branch lines LD1 to LDn through the first regulator 24b.

On the other hand, on the branch lines LD1 to LDn where the compressed air passes through the above-described first regulator 24b, a valve 26 is further provided to control the opening and closing degree by the operator or the controller 40. Can be done.

The valve 26 is a solenoid valve for controlling the opening and closing or opening / closing amount (opening amount) of the controller 40 by receiving the control signal of the controller 40 and the operator's operation, and applying the opening and closing degree to the controller 40. It is preferable to construct.

Alternatively, the valve 26 is configured as a solenoid valve in which opening and closing adjustment is simply performed by receiving a control signal of the controller 40 or an operator's operation, and opening and closing the solenoid valve on the solenoid valve or the branch lines LD1 to LDn. It may be made of a configuration in which the flow rate sensor 28 for measuring the supply flow rate of the compressed air through the degree or the branch line (LD1 ~ LDn) to apply the measurement signal to the controller 40.

Here, the installation of the valve 26 is not necessarily required, and in the case where the first regulator 24b is an electronically controlled regulator that can be adjusted by the operator or the controller 40, the installation of the valve 26 will be omitted. Can be.

Further, a diffuser 30 is provided at the end of the branch lines LD1 to LDn so that air is blown to the worker, and the diffuser 30 is installed within the interval already set by the diffuser 30. The presence or absence of a human body sensor 32 is applied to detect the presence and absence of the detection signal to the controller 40.

The human body sensor 32 may be an infrared sensor or an ultrasonic sensor.

On the other hand, the return line (LR) leading to the compression pump (22a, 22b) is further connected to the end of the air supply line (LS1), the return line (LR) with the air pressure already set in the direction of the compression pump (22a, 22b) The 3rd regulator 24c which adjusts and supplies is provided.

Here, the air pressure adjustment values adjusted by each of the first, second, and

third regulators

24a, 24b, and 24c have the highest air pressure adjustment value by the second regulator 24a, and the first regulator 24b. The air pressure adjustment value by is relatively the lowest, and the air pressure adjustment value by the third regulator 24c is preferably between the air pressure adjustment values by the first and

second regulators

24a and 24b.

On the other hand, when comparing the air pressure adjustment values exemplified above, the air pressure inside the air chamber 10 is in the range of 5 to 10 bar, and the air pressure adjustment value that is adjusted by the second regulator 24a, that is, the air supply line ( When the air pressure formed in LS1) is more than 4 bar and less than 5 bar, and the air pressure adjustment value adjusted by the 1st regulator 24b with respect to branch lines LD1-LDn is more than 1 bar and less than 3 bar, the 3rd regulator 24c Pneumatic pressure adjustment value range is adjusted through, it is preferable to form more than 3bar 4bar or less.

The setting of the air pressure adjustment value range according to the third regulator 24c allows the compressed air supplied through the air supply line LS1 to be preferentially supplied to the workers through the branch lines LD1 to LDn. The surplus of compressed air supplied to the workers is to be circulated back to the compression pumps 22a and 22b through the third regulator 24c.

In addition, the return line LR between the compression pumps 22a and 22b and the third regulator 24c temporarily stores the air flowing through the third regulator 24c and also flows in to allow the inflow of external air. It is preferable to further install a buffer chamber 34 having a port.

In addition, the buffer chamber 34 has an internal air pressure flowing through the return line LR via the third regulator 24c therein or above the predetermined range, or is driven by the compression pumps 22a and 22b. The first check valve 26 for intermittently allowing the inflow of air into the buffer chamber 34 when a vacuum pressure is formed therein, and the air from the inlet port when the pressure inside the buffer chamber 34 is less than or equal to a predetermined value. It may be provided with a second check valve 26 to allow the inflow of.

Here, the first check valve 26 is used to block reverse flow of external air through the return line LR described above, and the return line LR and the air supply line LS1 through the third regulator 24c. This is to prevent the pressure loss of the indiscriminately proceeding, which is not necessarily necessary, and when the vacuum pressure in the buffer chamber 34 is generated by the driving of the compression pumps 22a and 22b, By opening first, it is preferable that the cooled compressed air has a recirculation process before the external air.

In addition, the return line LR is connected at the end of the air supply line LS1 to be adjacent to the air supply line LS1 to a portion adjacent to the second regulator 24a, and side by side to the second regulator 24a. It is made by connecting to the third regulator 24c in a shape branching from the air supply line LS1 at an adjacent portion.

The air supply line LS1 and the return line LR are in contact with each other in order to mutually reduce the energy loss due to heat exchange from the production line. The air chamber 10, the compression pumps 22a and 22b, and the refrigeration cycle 16 are installed at a distance from the work space where the supply is made. Therefore, the air supply line LS1 and the return line LR are installed. This is to avoid forming a double.

Hereinafter, the operation method from the air conditioner of the production line using the compressed air described above will be described.

First, as shown above, the above-described first, second and

third regulators

24a, 24b and 24c differentially form respective air pressure adjustment values.

For example, the second regulator 24a sets the air pressure of the compressed air traveling from the air chamber 10 to the air supply line LS1 to any one air pressure adjustment value selected from a range of more than 3 bar and less than 5 bar. The first regulator 24b causes the air pressure of the compressed air that proceeds from the air supply line LS1 to the branch lines LD1 to LDn to be at a selected air pressure adjustment value within a range of more than 1 bar and 3 bar or less.

Further, the third regulator 24c may be set to the same or lower level as the air pressure adjustment value of the second regulator 24a and set to a higher air pressure adjustment value than the air pressure adjustment value of the first regulator 24b.

Here, forming the air pressure adjustment value of the third regulator 24c to be the same as the air pressure adjustment value of the second regulator 24a is continued through the second regulator 24a from the air chamber 10 forming a higher air pressure. By advancing the normal compressed air, the air pressure in the air supply line LS1 is recycled to overflow when the air pressure is formed above the air pressure adjustment value of the second regulator 24a.

In addition, forming the air pressure adjustment value of the third regulator 24c to be lower than the air pressure adjustment value of the second regulator 24a allows continuous flow of compressed or cooled compressed air to the air supply line LS1. It is for.

This is because when compressed air is not supplied (discharged) through the branch lines LD1 to LDn, that is, when compressed air is stagnant in the air supply line LS1, compressed air in the air supply line LS1. Heat energy is lost due to heat exchange with the production line, and when the worker is used in this state, the worker is allowed to use it for a certain time (the time until the compressed air that has lost the heat energy is exhausted from the air supply line LS1). This is to prevent the supply of compressed air rather than the desired temperature conditions.

And, forming the air pressure adjustment value of the third regulator 24c higher than the air pressure adjustment value of the first regulator 24b means that the compressed air on the air supply line LS1 is supplied to the worker through the branch lines LD1 to LDn. It is intended to be supplied preferentially.

On the other hand, the inside of the above-described ever chamber 10, as shown in Figures 4a to 5, the compressed air flowing through the air inlet line (LI) until the air is discharged through the air supply line (LS) One or more partitions 50 forming a flow passage of air are provided to bend the flow in a plurality of times.

The partition wall 50 installed as described above forms an air flow path so that the compressed air flowing into the air chamber 10 moves or circulates along an already designed evaporator / condenser 16 arrangement. In order to increase the frequency of contact with the compressed air.

Thus, the evaporator / condenser 18 in the air chamber 10 is arranged along the flow passage of compressed air including between the inner wall of the air chamber 10 and the partition 50 and between the partitions 50.

That is, the aforementioned partition wall 50 and the evaporator / condenser 18 are composed of a combination of mutual arrangements such that the flow of compressed air in the air chamber 10 increases the possibility of contact with the evaporator / condenser 18.

Here, various forms of the air chamber 10, the partition wall 50, and the evaporator / condenser 18 will be described with reference to FIGS. 4A to 5.

First, the air chamber 10a shown in FIG. 4A is provided with two or more plates at intervals in the air inflow line LI from the air inlet line LI with respect to opposite inner walls of the air chamber 10a. The compressed air can be made to have a zigzag flow.

As described above, the evaporator / condenser 18a is provided between the partition walls 50a in which the plurality of plates alternately alternately, that is, in the flow passage of the compressed air in the air chamber 10a along the flow of the compressed air.

The structure of the partition wall 50b of the air chamber 10b shown in FIG. 4B includes a flow passage formed by the partition wall 50b while guiding the flow of compressed air flowing from the air inflow line LI in one direction according to the design. Guide the air supply line LS along the evaporator / condenser 18b, and the compressed air that is not discharged through the air supply line LS or remaining is again along the flow path formed by the partition 50b. Direction so that the compressed air remaining in the air chamber 10b is continuously circulated.

At this time, it is possible to further install a blowing fan (60a) for forcing the circulation of the compressed air in the air passage through which the compressed air circulates in the air chamber (10b).

The air chamber 10c shown in FIG. 4C has the shape of a pipe standing vertically, such as a circle | round | yen and a polygon, when the shape of the perimeter of a side wall is planar view.

In addition, the partition wall 50c has one or more pipe shapes inserted vertically at intervals with respect to the inner wall of the air chamber 10c, each of which is a ceiling of the air chamber 10c corresponding to at least one of the upper part and the lower part, or Installation is made so as to separate or distinguish the inner space of the air chamber 10c having a side wall with a pipe shape in contact with the floor to the outside and the inside of the partition 50c.

Here, when the number of installation of the partition 50c is two or more, each of the partitions 50c is provided with different sizes from each other, and among these partitions 50c, the smaller ones are relatively larger in size. Installation is made with the gap inserted against the inner wall.

In the installation structure of the plurality of partition walls 50c, in one embodiment, the upper and lower portions of the partition walls 50c are installed to be in contact with both the ceiling and the bottom of the corresponding air chamber 10c so as to contact the inner side of the partition walls 50c. There may be cases where the outside is to be distinguished.

In this case, the partition 50c may be formed by cutting a part of the upper part or the lower part or installing the door D to open or close the part.

Installation of these cutouts or doors D is for making compressed air of the outer side (or inner side) of the partition 50c pass to the inner side (or outer side) direction of the partition 50c, The formation position is air The compressed air flowing into the chamber 10c flows from the upper side to the lower side or the lower side to the upper side of the partition 50c and then passes through the inside of the partition 50c to the inside of the partition 50c. It is preferable to arrange the compressed air flowing inwardly to flow from the lower side to the upper side or from the upper side to the lower side as opposed to the compressed air flow on the outer side of the partition wall 50c.

On the other hand, as another example, there may be a case where the number of installation of the partition wall 50c is two or more, and there is no shape portion cut off on the upper or lower portion, or those having no door D installed thereon.

At this time, the height of each of the partitions 50c is smaller than the distance between the ceiling and the floor of the air chamber 10c, and the installation of the plurality of partitions 50c is one of the upper air chambers in the order of being located from the outside to the inside. 10c), and the next neighbor is installed so that the lower side is in contact with the bottom of the air chamber (10c) and the upper and lower zigzag shape when the compressed air flowing through the air inlet line (LI) flows from the outside to the inside It is desirable to achieve.

That is, according to the other example above, the partition walls 50c having different sizes form a structure in which neighboring ones are alternately installed with respect to the ceiling and the floor of the air chamber 10.

In each of the above examples, the air chamber 10c is configured such that the inflow direction of the compressed air through the air inflow line LI is directed from the upper side to the lower side (or the lower side to the upper side) and at the same time around the partition 50c. Set the installation direction of the air inflow line (LI) to flow along the direction, that is, the flow direction of the inflowing compressed air to form a spiral shape or compress the air inflow line (LI) inside the air chamber (10c) connected to the site It may also consist of further installing a plate-like guide member 56, such as a rudder for directing the flow of air.

And, the door (D) presented in an example of the above description, may be installed in a shape that induces the flow of the compressed air passing through the partition 50c to form a spiral or swirl.

In this way, the installation of the evaporator / condenser 18c for arranging the plurality of partition walls 50c having different sizes so as to separate the inner space of the air chamber 10c at intervals from the inner wall of the air chamber 10c in the center direction thereof. Can be arranged along the flow direction of the compressed air guided by the partition 50c.

More preferably, as shown in Figure 4c, the refrigerant flow line (L) in which the refrigerant flows from the refrigeration cycle 16 to the air chamber (10c) in the air chamber divided by a plurality of partition walls (50c) ( 10c) Distributing pipes 54a (when 'evaporator / condenser' is 'condenser') are further provided for separating and supplying refrigerant to respective spaces inside, and each branched through the distribution pipes 54a. Of the evaporator / condenser 18c of the air chamber 10c is compressed between the inner wall of the air chamber 10c and the adjacent partition wall 50c, between each partition wall 50c, and in a single partition wall 50c installed at the center of the air chamber 10. It may be made by installing to correspond to the flow of air.

Then, in the refrigerant flow line (L) in which the refrigerant flows from the air chamber (10c) to the refrigeration cycle (16c), each evaporator / connected from each space inside the air chamber (10c) separated by the partition wall (50c) / The connecting tube 54b (when the 'evaporator / condenser' is a 'condenser') is installed to connect with the end of the condenser 18c and collect the refrigerant therefrom, and the refrigerant collected through the combining tube 54b is again provided. It may be made to have a circulation process flowing into the refrigeration cycle 16 through the refrigerant flow line (L).

Here, although the above-described distribution pipe 54a or coalescing pipe 54b is expressed as being installed outside the air chamber 10c in FIG. 4C, the present invention is not limited thereto, and a separate space is provided in the air chamber 10c. Naturally, it can be made of a configuration installed through the partitions 50c provided or arranged.

In addition, the above-described distribution pipe 54a or coalescing pipe 54b provides a flow of refrigerant to each space in the air chamber 10c divided by a plurality of refrigeration cycles 16 and partition walls 50c. A dispensing unit is formed.

To present a variation of this, although not represented in the drawings, an evaporator / condenser 18c is provided for each space in the air chamber 10c separated by the partition walls 50c, and these evaporator / condenser 18c is provided. Of course, it can be made by connecting the independent refrigeration cycle (16) for each.

The air chamber 10d shown in FIG. 4D, and the partition 50d and evaporator / condenser 18d structures provided therein have a pipe shape in which the side walls of the air chamber 10d are vertically erected, and the partition 50d is It is a plate-shaped thing with a length, and the edge part of the width direction makes contact with the ceiling and bottom surface of the air chamber 10d.

In addition, one end portion in the longitudinal direction of the barrier rib 50d is in contact with the inner wall of the air chamber 10d around the air inflow line LI, and the remaining portion is in contact with the inner wall of the air chamber 10d, as shown in FIG. 5. In the direction of the air inlet line (LI) in the form of a first bent shape, and then in plan view when the other end portion continuously along the vortex phenomenon of Archimedes to form a structure reaching the center portion of the air chamber (10d).

The evaporator / condenser 18d corresponding to the installation of the bulkhead 50d has a conical shape in which the portion extending from one side to the other side follows the helical shape of Archimedes when viewed from the plane of the air chamber 10d. According to the arrangement may be made to have a continuous slope from the upper side to the lower side.

Here, the side shape of the evaporator / condenser 18d is inclined downward along the cone shape. In the case of the evaporator, the liquid refrigerant flows into the gas through the lower portion of the center of the air chamber 10d and changes in the gas state. After passing through the upper part to facilitate passage, the condenser prevents the liquid refrigerant from accumulating in the flow passage of the refrigerant when the gaseous refrigerant flows into the liquid state through the upper portion of the air chamber 10d. It is designed for.

This design shows that one partition 50d and one evaporator / condenser 18d can be made in one air chamber 10d.

In each embodiment described above, it is preferable that the above-described installation of the evaporator / condenser 18d is in contact with the surface of the partition wall 50d corresponding to the arrangement.

This is for the partition 50d to enlarge the specific surface area of the evaporator / condenser 18d to increase the possibility of collision (heat exchange) of the compressed air.

In addition, on the inner wall of the air chamber 10d, the surface of the partition 50d, and the surface of the evaporator / condenser 18d, as shown in FIG. 4C, in the air chamber 10d separated and separated by the partition 50d. For each space, the wing plate 56 for guiding the flow of air moving from the upper side to the lower side or the lower side to the upper side in a spiral shape may be further disposed in a spiral shape along the vertical direction.

The function of the wing plate 56 may also be achieved by cooling fins provided in the evaporator / condenser 18d, as shown in FIG. 4C.

The installation of the vane 56 and the cooling fins described above is also intended to increase the likelihood of collision (heat exchange) of compressed air against the evaporator / condenser 18.

The air chamber 10e of FIG. 4E is a blower fan which provides a blowing pressure to flow in the direction of the evaporator / condenser 18e while forcibly circulating the compressed air therein without a partition for inducing the flow of compressed air therein. It can be made only by the installation of (60b).

The air chamber 10f shown in FIG. 4F is provided with a plurality of air chamber 10d structures identified in FIG. 4D described above, and shows connecting them up and down.

In this case, the air inlet line (LS) of each of the air chamber (10d) and the air supply line (LS) and the evaporator / condenser (18f) may be made to have a connector port (C) for the corresponding connection, respectively. Each of these connector ports C is preferably formed with a valve (not shown) that prevents the flow of fluid in the absence of its corresponding connection.

On the other hand, the branch line (LD) between the first regulator 24b and the diffuser 30, as shown in Figure 6 and 7, the main pipe (60a) forming a flow passage of the compressed air made of a flexible synthetic resin material and The cover tube 60b and the cover tube 60b form a space between the main tube 60a and the outside and surround the spacer tube 60 through one or more ribs 62 protruding from the outside of the main tube 60a. A double pipe (60) integrally formed with a plurality of wire cables (C / L) extending in the longitudinal direction by being arranged in a plurality of numbers along the circumference of the isolation space or the outer surface; Sockets of female or male

structure having joints

66a and 66b for communicating with main pipe 60a at each end of double pipe 60 and electrically connected to each wire cable C / L, respectively. It consists of the structure provided with 64a and 64b.

In the branch line LD, the above-mentioned male and female divisions of the

sockets

64a and 64b form a plug PL for electrical connection, which is called a socket 64a of a male structure, and a socket of a male structure ( 64a) can be divided into a female socket 64b having an outlet structure through which the plug PL is inserted.

Here, the

sockets

64a and 64b provided at both ends of the above-described double pipe 60 may be differently connected to each other, or may be configured to selectively connect the same structure to each other.

As described above, the branch line LD formed as described above with reference to FIGS. 1 and 2 is provided with the compressed air through the first regulator 24b through the presence or absence of a signal from the human body sensor 32 installed in the diffuser 30. It is to reduce the pressure loss of the compressed air by blocking the flow in a position close to the air supply line (LS).

In addition, the compressed air in the double pipe 60 is naturally discharged in the absence of the operator so that the inside is at normal pressure, and cooling or heating air through the opening of the first regulator 24b when the operator is in the working position. It is desirable to be able to supply quickly.

In addition, the air supply line LS is composed of steel pipes to maintain the internal pressure, and is installed at a predetermined design position with respect to the production line, and the branch line LD is far from the air supply line LS. Or to provide the operator with cooled or heated compressed air at least one or more connections to the workspace where the installation is difficult to arrange in a straight line.

In other words, the branch line LD can easily cope with the location conditions of the work space, and can quickly perform the supply of compressed air to the presence or absence of an operator while preventing the temperature loss of the compressed air in the section leading to the work space. Make sure

In FIG. 1 and FIG. 2, reference numeral “LS2” indicates that the compressed air inside the air chamber 10 can be further connected to an air gun (not shown) used by a production facility or an operator, and “12b”. Is a second pressure sensor for detecting the presence of pressure abnormality in the air supply line (LS1), "14b" is a second temperature sensor for measuring the temperature conditions in the air supply line (LS1) or production line, through which the refrigeration cycle (16) To compensate for the driving conditions.

The method of operating the air conditioner of the production line using the compressed air described above will be described.

First, the controller 40 sets the pressure range formed by the compressed air in the air chamber 10 in one or more steps at different stages (ST110).

Here, the differentially setting the pressure range inside the air chamber 10 is a large number of branch lines LD1 to LDn branched from the air supply line LS1, and the amount of compressed air used by workers. This is to cope with the case where it cannot be predicted.

On the contrary, when the number of branch lines LD1 to LDn branched from the air supply line LS1 is small and the amount of compressed air supplied to the workers is limited, the pressure range inside the air chamber 10 is differentially divided. To do that can be meaningless.

To illustrate this, in the pressure inside the air chamber 10 to be in the range of 5 bar or more and 10 bar or less, a quarter of the number of branch lines LD1 to LDn out of the total branch lines LD1 to LDn. When the compressed air is consumed, the pressure inside the air chamber 10 is maintained at about 5 to 7 bar, and half of the branch lines LD1 to LDn of the total branch lines LD1 to LDn are maintained. When the compressed air is consumed, the pressure inside the air chamber 10 is in the range of 7 to 8 bar, and 3/4 of the branch lines LD1 to LDn are included in the total branch lines LD1 to LDn. When the compressed air is consumed through, the pressure inside the air chamber 10 is in the range of 8 to 9 bar, and when the compressed air is consumed through all the branch lines LD1 to LDn, the air chamber (10) The pressure inside can be in the range of 9 ~ 10bar.

That is, the pressure setting inside the air chamber 10 is differentially divided according to the consumption of compressed air through the branch lines LD1 to LDn.

The differential classification of the pressure inside the air chamber 10 is to reduce the energy consumption associated with the driving by refraining from unnecessary driving of the compression pumps 22a and 22b and driving them to a required level.

In addition, the controller 40 frequently checks the pressure in the air chamber 10 through the first pressure sensor 12a (ST112), and when it is determined that the air pressure in the air chamber 10 is equal to or less than the set value (ST114), The compression pumps 22a and 22b are driven to be maintained at a level corresponding to the set value (ST116). When the air pressure inside the air chamber 10 is equal to or higher than the set value, the driving of the compression pumps 22a and 22b is stopped and unnecessary. Reduce energy consumption (ST118).

In this way, the controller 40 stores a reserve amount of compressed air in the air chamber 10 in response to the consumption amount through the branch lines LD1 to LDn.

When the discharge of compressed air through the branch lines (LD1 ~ LDn) increases or decreases in comparison with the previous set value in the process, the controller 40 is the human body sensor 32, the flow sensor 28, The supply amount of the compressed air is frequently measured based on whether the first regulator 24b or the valve 26 is opened or closed (ST120), and the measured value is compared with the set value inside the air chamber 10. It is judged whether or not (ST122), and the condition is changed to adjust the set value inside the air chamber 10 corresponding to the measured value for the current supply amount of compressed air (ST124).

In this way, the controller 40 allows to maintain the supply of compressed air to the operator by repeating the above process.

In addition, the temperature setting of the compressed air supplied to the workers in conjunction with the adjustment of the air pressure adjustment value of each of the above components is as follows.

First, as in the differential pressure range of the compressed air in the air chamber 10 in one or more steps, the temperature inside the air chamber 10 according to the differential of each pressure range is set (ST210).

The setting of the temperature inside the air chamber 10 is to set the time and the output of the driving of the refrigeration cycle 16 after all, and this is also compressed air newly introduced by the supply amount of the compressed air supplied to the worker. In response to this, the cooling time is formed.

Therefore, the controller 40 measures the temperature in the air chamber (C) through the first temperature sensor 14a (ST212), and determines whether the measured value is in a preset temperature range (ST214).

At this time, when the temperature inside the air chamber 10 is within the set value range, the controller 40 stops driving the refrigeration cycle 16 (ST218), and if it is not within the set value range, the refrigeration cycle 16 ) Is controlled to cool the compressed air inside the air chamber 10 (ST216).

In addition, the controller 40 measures the discharge amount of the compressed air through the branch lines LD1 to LDn through any one of the flow sensor 28, the first regulator 24b, and the valve 26 (ST220). The measured value is compared with the pressure range condition for the inside of the air chamber 10 to determine whether to adjust the pressure setting condition in the air chamber 10 (ST222).

From this, when it is determined that the temperature setting condition for the compressed air inside the air chamber 10 is necessary, the controller 40 changes the temperature setting condition corresponding thereto (ST224) and reflects this to drive the refrigeration cycle 16. To control.
