Description

[Detailed description of the invention] This proposal relates to an air conditioning system for workstations, and its purpose is to enable efficient use of office equipment such as computer terminals and word processors as they become more versatile. In addition, in order to prevent noise from spreading into other office spaces, when creating and using a workstation consisting of multiple office compartment spaces indoors, it is necessary to improve the air conditioning effect in each compartment. The point is that.

Normally, air conditioners such as coolers are installed in several corners of the room depending on the size of the office space, and these are used to cool and heat the entire space. As described above, if a large number of divided spaces are formed in a room, it not only obstructs the air flow throughout the room, but also causes the problem that the air flow within each divided space is extremely deteriorated and the air conditioning is not effective. Moreover, if various types of OA equipment were installed and used within this divided space, there remained the problem that the heat and odors generated by these equipment would remain in the space, further worsening the working environment. .

This project was devised to solve these problems, and its gist is to supply air conditioning or heating for cooling or heating from an air supply pipe that is connected to the air supply port of an air conditioning air supply source installed at a suitable location indoors or outdoors. Air is divided into at least one air supply port formed in each compartment space to enable air conditioning in each compartment space, and when air conditioning is stopped by cutting off air supply in any compartment space or air supply Sensors such as limit switches are installed on the air supply ports of all compartments of the workstation in order to prevent excessive air supply to other compartment spaces that are in operation when controlling the amount of air supplied from the ports. Each sensor is connected to the control unit, and the control unit and the blower motor of the air supply source are connected to detect the opening/closing and degree of opening of the air supply port in each compartment space, and this detection signal is sent via the control unit. By controlling the rotation of the motor by inputting it as an operation signal to the blower motor, it is possible to prevent the air conditioning effect of other compartment spaces in use and to suppress energy loss.

The present invention will be explained below with reference to the attached examples. For example, as shown in FIG. 1, a desk 1 is connected to a partition wall 2,
2. A document locker 3 and a partition panel 4 are used to enclose a section leaving an entrance 5 and separate it from the office space to form a sectioned space DS, and a workstation is created by forming a large number of such sectioned spaces DS.
When a WS is configured, at least one air inlet 6 is formed at a suitable location in each compartment space DS, in the illustrated example, at the connecting corner of both partition walls 2, and these air inlets 6 are connected to branch pipes 7. The air supply pipe 8 is connected to an air supply pipe 8 through a space 9 separately provided between the back plates of both desks 1 or at the bottom of the partition wall 2 of the adjacent compartment space DS and an opening formed in the partition panel 4. 1
One end is connected to an air supply port of an air supply source 11 installed at a suitable location indoors or outdoors, and the other free end is closed.

Thus, the air supply ports 6 of each compartment space DS can be individually opened and closed, the direction of the wind can be changed, and the degree of opening can be adjusted.For example, as shown in FIG. 3, the lower end is connected to the branch pipe 7 for communication. At the same time, a control plate 14 for regulating the amount of air supplied from the air outlet 12 is integrally fixed to a pivot 15 in a box 13 in which an air outlet 12 is formed on the front surface of the upper end.
The control plate 14 is rotatably supported by bearings 16 disposed opposite each other in the box 3, and an adjustment knob 17 is integrally fixed to the front end of the pivot 15, which rotates the control plate 14 in the box. The upright state shown in FIG. 3 is a fully open state, and the horizontal state is a closed state, and the opening degree is adjusted to a desired degree.

Therefore, if the air supply port 6 of each compartment space DS can be individually adjusted to adjust the amount of air supplied, the second
As shown in the figure, in the proposed air conditioner configured by branching one air supply source 11 air supply pipe 8 into a plurality of compartment spaces DS, if the air supply port 6 of any compartment space is closed, the air supply for that amount will be increased. The internal pressure of the trachea 8 increases, and the amount of air blown out from the air supply ports 6 of the other compartment spaces in use becomes excessive than the set amount of condensed air from the respective opening degrees, which reduces the air conditioning effect in the space. In addition to disturbing the air supply 11, overpressure may build up inside each air supply port 6 and cause damage to components.
Since there is a problem of energy loss, in this proposal, as shown in Fig. 3, when the control board 14 in the box 13 is fully closed, it comes into contact with the control board 14 and issues an ON or OFF signal. A sensor 18 such as a limit switch is provided, and the sensor 18 of each air outlet 6 is connected to a control unit 19 connected to the blower motor m of the air supply source 11 as shown in FIG. 6 is closed, a closing signal from the corresponding sensor 18 is input to the control unit 19, and it is determined in the control unit 19 how many sensors 18 close signals have been input, and a comparison input in advance is made. A circuit or the like converts the input signal into a control current and sends this control current to the blower motor m to control the rotation of the motor, thereby reducing the supply pressure into the air supply pipe 8 during use. This prevents excessive air from being supplied to the air supply ports 6 of the other compartment spaces DS. As a result, even when the air inlet 6 of one or more of the plurality of compartment spaces DS is closed, this closing operation is detected by the sensor 18 such as a limit switch and the control unit 19 detects the closing operation. By sending a control current to the blower motor m of the air supply source 11, the supply pressure of the air supplied from the air supply source 11 is lowered and adjusted to the air supply port 6 of the other compartment space in use. It is possible to control the supply air amount so that it does not become excessive, so that when any of the air supply ports is closed, the supply pressure in the air supply pipe 8 and other air supply ports increases and the air supply pressure in the air supply pipe 8 and other air supply ports increases. Air conditioning in the divided space may be disturbed, air may leak from the connection between the air supply pipe 8 and the branch pipe 7, or the connection between the box 13 and the branch pipe 7, etc., or the air supply port box 1 may be damaged due to excessive pressure.
This makes it possible to completely prevent defects such as damage to the control plate 14, etc. inside the control panel 3. In addition, the internal configuration shown in FIG. 5 not only simplifies the configuration and assembly of the air inlet 6, but also allows the air volume to be adjusted easily and reliably.

The above-mentioned sensor 18 not only detects the fully closed state of each air outlet 6, but also detects stepwise the predetermined degree of opening and applies a control current to the blower motor m via the control unit 19 based on the degree of opening. It is also possible to control so that excessive air is not supplied to the air supply port 6 of the compartment space DS in use by sending
In this case, a plurality of sensors 18 are provided in stages according to the degree of opening of the control plate 14. still,
As shown in FIG. 5, the human power signal detection structure for controlling the blower motor m is as shown in FIG. An air volume control valve 23 for adjusting the opening degree of the pipe 7 is provided, and a knob 17 is fixed to the outside protruding portion of the adjustment shaft 23' of the air volume adjustment valve 23, and a protrusion 2 is attached to the adjustment shaft at an appropriate position.
4, which can be engaged with a sensor 18 such as a limit switch provided in the bottle 13. With such a configuration, control can be performed as shown in the embodiment shown in FIG. There is an advantage that not only the structure is simple as there is no need for a spring or the like to hold the plate 14 at a predetermined opening degree, but also the air volume adjustment operation can be performed easily and reliably.

In addition, in the present invention, a plurality of louvers 20 whose angle can be changed are provided at the air outlet 12 formed at the upper end of the box 13.
A circular deflection plate 21 with
The direction of air supply from the air outlet 12 can be changed by the operation of 0.

According to the air conditioner in the workstation of the present invention as described above, the office space is divided into a plurality of divided spaces DS...
When partitioning into WS and using it, each partition space
Forming at least one air outlet 6 in the DS,
By connecting each air supply port via branch pipes 7 and air supply pipes 8 to an air supply source 11 placed at an appropriate location indoors or outdoors, each workstation WS where effective air conditioning cannot be achieved with conventional air conditioning equipment It can improve the air-conditioning effect of the divided space, and especially when office equipment such as computer terminals and word processors is installed, the hot air and odors from these equipment will be trapped inside the workstation and cause poor working conditions. In such cases, in addition to air conditioning using the existing air conditioning equipment in the office space, suitable working conditions can be achieved by adjusting the air conditioning for each compartment space according to the user's preferences. In addition, an air supply pipe 8 connected to the air supply source 11 and a number of branch pipes 7 branched from the air supply pipe 8 are arranged in a space 9 provided between both desks 1 and 1 of the adjacent compartment space DS. Accordingly, the piping and the like can be connected to the air supply port 6 formed at an appropriate location within the partitioned space DS without exposing the piping to the outside and impairing the appearance.
