Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner having a fire prevention function that has both ventilation and fire prevention functions. The number of public facilities such as underground shopping malls and public halls is rapidly increasing, and considering that a large number of people gather underground and vehicles pass through, ventilation is required from the viewpoint of human life safety. and disaster prevention equipment are being shown in close-up.

Currently, relatively small ventilation equipment is used for small spaces.
Currently, disaster prevention equipment is being used to deal with this issue, and in order to deal with underground spaces that will continue to expand and become wider in the future, it is normal to have a base duct that is different from the conventional one. Therefore, there were disadvantages such as increased equipment and management costs and the need for a large construction space.

The purpose of the present invention is to solve the above-mentioned difficulties at once by providing both ventilation and fire prevention functions, and to reduce equipment and management costs as well as to reduce construction space. The gist of the invention is to arrange a plurality of sills horizontally at equal intervals above and below, and to provide a damper for each blade.・Zo-frame (two frames are installed and supported so that they can be opened and closed freely, and are synchronized and interlocked), and stone plates are installed on the upper and lower inner surfaces of the Dan saw, and the blade ends are attached to the stone plates. This is an air conditioning system having a fire prevention function, characterized in that a landing plate is stretched on the side where the brake P contacts the tip of the brake P.

Hereinafter, the configuration of one embodiment of the present invention will be described with reference to the drawings.A plurality of blades 2 are positioned horizontally on a Dan-ξ-frame 1 and are arranged vertically equally spaced apart.
is supported by a damper shaft 3 which is connected at both ends by plug welding to the damper frame 1 so as to be openable and closable. The fork form frame body 4 is installed at a prescribed position at a prescribed angle with respect to the sill R2, and each blade 2 is rotatably installed between the forks of the frame body 4 through the middle of the bin 5. The rods r7 are inserted through the holes 6 respectively (connecting rods are connected with two twists, and are freely connected to the other end of the link arm 8 with one end fixed to the arbitrary Dan/ξ-shaft 3a by means of a pin 9). 10 is associated with the tip of the rod 12 of, for example, an air cylinder 1 fixed on the outside of the damper frame 1, and the reciprocating movement of the rod 12 due to the operation of the air cylinder II causes the blade 2a to move toward the damper shaft 3.
The blade 2 opens and closes around a, and in conjunction with the opening and closing, all other blades 2 similarly synchronize via the rod 7 to open and close around the Dan-ξ-axis 3 ( −
It is composed.

At the tip of each brake R2, a sealing strip plate 13 made of a thin stainless steel plate having sufficient S-flexibility is attached to a rivet 15 by a mounting plate J4 in order to ensure low leakage when the brakes P are closed. The blades 2 are integrally connected and fixed with a seal so that there is no contact gap between the blades 2, and the gap between the ends of the damper frame 1 and each blade 2 is filled with the same type of material as described above stretched on the inner surface of the damper frame. The side plate 16 is made of a thin stainless steel plate and is sealed so that there is no contact gap.

Stone grooves are installed on the upper and lower inner surfaces of the Dan/e-frame 1, respectively.
When the plate 17 is installed and the blades 2b and 2c at both the upper and lower ends are closed, the sealing strip plate 13 is pressed against the stone groove plate 17 to connect the blades 2b and 2c at the upper and lower ends to the dunnium chisel frame 1. A normal air IA] Danno ξ function is configured by sealing so that there is no gap between the two.

As shown in FIGS. 3 and 4, the blade 2 is configured in a clasped shape to provide a space 18 inside the blade, so that when the blade 2 is closed and one side is irradiated with flame, the inside of the blade 2 is closed. A temperature difference is provided between the outer plates, and the brake P2 is placed on the flame side (= uniformly warped.
The shaft 3 has its play F′ as described above to cope with thermal expansion.
20 both ends (divided into two, space 18 from both ends of blade 2)
When the flame comes from the direction indicated by the arrow in FIG. The blade 2b is manufactured so that the other blades 2 and the upper blade 2b are warped in the same way.

A landing plate 19 is stretched on the side where the end of the blade 2 comes into contact with the stone plate 17 (second) at a position where the tip of the brake r comes into contact with it, so that the arrow shown in FIG. When the flame comes from the indicated direction, there will be a gap f between the stopper plate 17 and the lower blade 1'2C, and this gap will be 20 mm to 70 mm l2 depending on the width of the blade. If there is no plate 19, the flame will escape to the opposite side through the gap, but if the brake 1'2c is warped by the landing plate 19, the tip of the blade will come into contact with the upper surface of the landing plate 19, thereby causing the flame to escape to the opposite side through the gap. There is one type that eliminates the space for the flame to escape to the opposite side and can completely block the flame, and one type that has an air conditioning damper function and a fire prevention damper function.

As described above, the present invention normally functions as an air-conditioning saw, and even if one side of the saw is heated to a high temperature due to the flame during a fire and the blade is bent or deformed due to thermal expansion, the blade will not be damaged. It is said that the flame escapes because the tip moves so that it touches the top surface of the landing plate.20
No gaps larger than 2 mm are formed, and therefore,
There is no gap for the flame to escape to the other side, and it has a sealing property and performs the fire prevention function of preventing flames.

As is clear from the explanation in item 1, the present invention has an air conditioning damper function that normally provides ventilation, and also has a fire prevention function that blocks flames in the event of a fire (2), so the equipment is large. It is greatly simplified, which makes it easier to manage, and the installation space is significantly reduced, contributing to economic efficiency and labor savings.
