JPH01285723A - Indoor ventilating, air discharging and smoke discharging device - Google Patents

Abstract

PURPOSE:To discharge poisonous gas, smoke and the like immediately and suck fresh atmosphere simultaneously upon emergency to minimize an accident by a method wherein a damper B is closed perfectly and the damper A is opened perfectly by the operation of a detector provided in a room upon discharging smoke to discharge full amount of poisonous smoke generated in the room. CONSTITUTION:When a detector 15 is operated by some cause and generation of abnormality in a room is detected, a damper B is closed perfectly and the damper A is opened perfectly while a ventilating fan 6 is rotated in a high speed to discharge full amount of poisonous smoke through an air discharging port 4 simultaneously with detection. Outdoor fresh air is made to flow into the room through an air supplying port 3 simultaneously with the smoke discharging operations to supply oxygen whereby danger due to carbon dioxide may be eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention quickly eliminates harmful smoke and indoor smoke/odors in the event of a building fire, and automatically receives fresh air from outside to prevent accidents. This relates to so-called indoor return air, exhaust, and smoke evacuation equipment that attempts to prevent the occurrence of such occurrences.

[Conventional technology]

Conventionally, various mechanical devices have been developed as return air/exhaust mechanisms for indoor rooms, but most of these have the main purpose of simply returning indoor air only. Therefore, in the event of a building fire, etc., it could not perform any effective and appropriate functions such as eliminating harmful smoke.

[Problem to be solved by the invention]

The present invention is normally used as an indoor cooling/heating air return device in the event of an emergency as described above, and in an emergency, it simultaneously eliminates harmful gases, noxious smoke, etc., and at the same time brings in fresh air from outside to minimize accidents. We aim to provide return air and exhaust/smoke removal equipment whose main purpose is to

[Means to solve the problem]

In order to achieve the above objects, the present invention provides a return air port, an air supply port,
A U-shaped ventilation passage is formed by communicating the above-mentioned openings inside the machine body, which has an exhaust port, an outside air intake port, etc., and a return air/exhaust blower and a supply air blower are installed in the air passage. And in an air conditioner in which various mechanisms such as a filter, a heat exchange coil, an eliminator, etc. are respectively arranged, dampers A and B are provided in the exhaust port, the outside air intake port, and the ventilation passage.

C are interlocked and connected so that they can be opened and closed, respectively, and the damper A
The feature is that damper B is connected to a detector installed indoors, and damping occurs when smoke is exhausted due to the activation of the detector.

[For production]

In the above, for example, when a fire occurs, the detector is activated and damper A is automatically opened, allowing all of the harmful smoke that fills the room to be released directly from the return air vent and the damper A. C@ can be opened and only the required amount of outside air can be supplied into the room.

〔Example〕

A return air port (2) and an air supply port (3) from the room are installed on the top of the machine casing (1), and an exhaust port (4) and an outside air intake port (5) are installed on the side.
), and the return air blower (6) and the same electric motor (6) are installed inside the return air port (2).
) A supply air blower (7) and the same electric motor (7) as above are installed inside the machine, and a substantially U-shaped ventilation passage (8) is formed inside the machine, and a pre-filter (9), Main filter α01 heat exchange coil (6), eliminator (2),
Various mechanisms such as a reheating electric heater, a hot water coil (total), a humidifier αa, etc. are arranged.

The present invention has the above-mentioned mechanism, and furthermore, a damper A is connected to the exhaust port (4), a damper B is connected to the ventilation passageway (8) in a freely openable and closable manner, and the outside air intake port (5) is also connected to the outside air. Install each intake damper C.

Further, each of the dampers A, B, and C is connected to an indoor smoke/fish fire detector 09, an automatic control device, etc., and is automatically opened and closed by a motor.

Incidentally, under normal conditions, when the damper C opens, the outside air from the outside air intake port (5) is heated and cooled to an appropriate temperature by the heat exchange coil Ov, and the air is then transferred to the air supply port (3). Cleaner air is constantly supplied indoors. In addition, at the same time as the outdoor air is received, the indoor contaminated air is removed by the damper Aefll.
Due to the closed circuit of the 1m damper B, the air is discharged outdoors from the exhaust port (4) via the return port (2), but in this case, the damper B is not completely open, but has a semi-open circuit, so that the indoor air released above is The purpose is to reduce heat exchange energy by returning a portion of the heat to the ventilation passageway (8).

In such a state, the detector (to) is activated for some reason, detects the occurrence of an abnormality in the room, and at the same time, the damper B side is completely closed and the damper λ side is completely opened,
Furthermore, the return air blower (6) rotates at high speed and rapidly exhausts the entire amount of harmful smoke from the room through the exhaust port (4).

Moreover, at the same time as the above operation, fresh air from outside flows into the room from the air supply port (3) to supply oxygen and eliminate the danger caused by carbon dioxide gas.

It goes without saying that the above-mentioned air intake/displacement amount can be determined at will by adjusting the opening and closing of the dampers A and C, as well as adjusting the strength of the blower.

In the figure, the symbol @0Q indicates a control valve, the symbol a indicates a drain pan, and a vibration-proofing spring α9 is attached to each of the blowers (6) and (7).

〔Effect of the invention〕

As explained above, the present invention constantly supplies and distributes outdoor fresh air indoors at an optimal temperature by opening and closing the dampers AsB and AsC, and at the same time exhausts contaminated air outdoors. Since all harmful smoke is immediately released outdoors, and at the same time only the necessary amount of fresh air from outdoors is delivered indoors, it is possible to completely eliminate accidents caused by lack of oxygen and harmful smoke in the event of a building fire. Moreover, it is an extremely socially beneficial invention.
