Since the evaporative cooling device is used in a multi-use facility, a fine mist spray mist nozzle is adopted for fine mist spray to prevent water condensation and water dripping. The fine mist spray mist nozzle has an individual spray capacity of 30 to 40 CC / min, a linear reach of the mist sprayed through the mist nozzle is within 2 meters, and a particle size of water sprayed through the nozzle is also 10 to 20 μm. Therefore, it may be insufficient to suppress the propagation of fire with fine mist spray mist nozzles that are individually sprayed.

Sprinklers extinguish a fire or extinguish a fire by spraying water of up to 120 L / min per nozzle to suppress fire propagation, or suppress fire propagation. However, since a large amount of water is sprayed in all directions, unnecessary property damage may occur. Furthermore, powder fire extinguishers have a narrow spraying range, making them uneconomical to use in large areas such as traditional markets, arcades, or shopping malls.

This embodiment is to supplement and solve the problems of the prior art described above. That is, by providing a fire diffusion delay device interlocked with the evaporative cooling device, the fire can be suppressed early in the event of a fire in the same evaporative cooling device, or the diffusion of the fire can be suppressed. It is to provide a fire diffusion delay device interlocked with the evaporative cooling device.

The fire diffusion delay apparatus according to this embodiment includes: an evaporative cooling unit that performs cooling by spraying a fluid mist, a fluid pipe, and a plurality of fire diffusion delay spray nozzle units arranged along the fluid pipe to spray fluid mist, A plurality of solenoid valves that are connected to the fluid piping to provide or block fluid to a plurality of fire diffusion delay spray nozzle units, and a plurality of fire sensors that are arranged at regular distances along the fluid piping to monitor for fire signs. A plurality of solenoid valves to provide fire indication information detected by a pump and fire sensors providing fluid through a fire diffusion delay unit and a fluid piping, including at least some of the plurality of fire diffusion delay spray nozzle units spraying fluid It includes a control unit for controlling at least some of.

However, this is an embodiment, and of course, it is possible to perform a modification according to an environment of a place where the present embodiment is installed.

Heat is gathered in the high places adjacent to the ceilings of traditional markets, public facilities, arcades and warehouses, and the temperature rises relatively. The evaporative cooling unit 400 lowers the ambient temperature by using evaporation heat by spraying a fluid mist with a mist spray nozzle 412 at a height, spraying the fluid mist with a spray fan 422 and convecting air to surround It lowers the temperature, suppresses the increase in relative humidity, and lowers the sensation temperature.

To do. In addition, in the winter when cooling is unnecessary, the fluid contained in the first cooling pipe P1 and the second cooling pipe P2 may be drained to prevent freezing of the pipe. In one embodiment, the first drain valve S1 and the second drain valve S2 may be solenoid valves.

The control unit 300 receives the fire indication information from the fire sensor 130 through a wired and / or wireless communication environment and controls the evaporative cooling unit 400 and the fire diffusion delay unit 100. In one embodiment, the control unit 300 may be implemented as a microprocessor (MP), a microcontroller unit (MCU), and as another example, the control unit 300 may be implemented as a computer.

An operation example of the fire diffusion delay apparatus 10 according to this embodiment will be described with reference to FIGS. 1 to 3. Before the fire occurs, the diffusion diffusion delay unit 100 does not work, and the evaporative cooling unit 400 is operated to cool the installed place. As described above, the mist spraying unit 410 may spray the fluid mist to the height of the place where the evaporative cooling unit 400 is installed, and remove the heat formed in the height using evaporation heat to perform cooling, and the convection unit ( By using the fan included in 420), air can be convected to lower the relative humidity and perform cooling to lower the sensation temperature.

When a fire occurs, the fire sensor 130 detects heat and / or smoke, which are signs of fire, and provides fire indication information to the control unit 300 through a wireless or wired communication network. In one embodiment, the control unit 300 that has received the fire indication information may notify the fire station of the fire. For example, the controller 300 may notify the fire occurrence through wired, wireless communication, text message, or social network service (SNS).

The control unit 300 receiving the fire indication information stops the operation of the evaporative cooling unit 400 and drives the fire diffusion delay unit 100.

Open to cause the fire diffusion delay spray nozzle unit 110 to spray the high pressure, high speed fluid mist provided by the pump 200.

As described above, since each of the fire diffusion delay spray nozzle units 110 is disposed so that the injection ranges overlap, the control unit 300 spreads the fire adjacent to the location of the fire sensor 130 providing the fire indication information. The solenoid valves can be controlled so that all of the delay nozzle units 110 spray the fluid mist.

In order to cause fire to spread, heat, oxygen and oxygen are required, and the fire spreads as the surrounding oxygen is supplied and the heat reaches the ignition point of the raw material. However, the mist sprayed at high pressure from the fire diffusion delay spray nozzle unit 110 minimizes the oxygen supply to the generation zone, instantaneously lowers the ambient temperature due to the evaporation effect, and the fire diffusion delay spray nozzle The fine mist sprayed by the (collider nozzles) unit 110 penetrates to the lower ignition point or the space where the water does not close to extinguish the fire or prevent delay and spread.

If the fire sensor 130 can no longer detect heat and / or smoke, it can be determined that the fire has been extinguished. If the fire sensor 130 does not provide fire indication information, the control unit 300 opens the valve S to discharge residues such as air remaining in the fluid pipe 130. Subsequently, the control unit 400 may ventilate the ambient air by driving the evaporative cooling unit 400. In addition, the fan 422 included in the convection portion 420 of the evaporative cooling unit 400 operates to discharge smoke from the fire to the outside using forced convection, thereby minimizing human damage caused by smoke.

According to the present embodiment, it is possible to minimize unnecessary property loss by not spraying water in all directions like a conventional sprinkler, and suppress fire and suppress fire in a wide area without using an expensive powder fire extinguisher. Being able to do it provides the economic advantage.
