The fire extinguishing system including the fire detection unit unit, the automatic and manual fire extinguishing unit unit, and the fire alarm unit unit described above is operated under the control of the control unit together with the air conditioning system. 10 is a diagram illustrating a configuration of an automatic fire extinguishing system centering on a control unit. In the case of fire detection and fire extinguishing systems, rapid detection and operation of the fire extinguishing system are also important, but it is also very important to prevent unnecessary injection of extinguishing gas or extinguishing fluid due to fire detection errors and malfunctions. There is also a need to switch to manual fire extinguishing. The present invention uses the following characteristic control method to satisfy this requirement.

5 is a flowchart illustrating a system operation performed by a controller. The control unit of the air conditioner with a fire extinguishing system of the present invention outputs a primary fire alarm through the fire alarm unit unit when a primary detection signal is input from a fire detection unit unit, and t seconds after input of the primary signal. If a second signal is input from the fire detection unit after the elapsed time, the second fire alarm is output through the fire alarm unit, and after t seconds elapse after the second fire alarm is output, the air conditioning system is stopped and the automatic fire extinguishing unit is It is characterized by releasing the extinguishing gas by operating.

In the primary detection and the secondary detection by the fire detection unit, the primary detection is performed at a high level of sensitivity by setting a reference level according to the sensitivity of each sensor, and the secondary detection is performed at a low level of sensitivity. At least, depending on the fire detection level, by setting the first detection to detect what one or a small number of sensors of a plurality of sensors, and the second detection to detect what many or all sensors detect. Two or more detection signals are set and thus fire alarms are respectively output. In the case of the second fire alarm, the level of sound or light output from the buzzer or alarm lamp is different from the first fire alarm, or the number of output units is increased to increase the level of alarm step by step. It is desirable to. In addition, it is preferable to set an elapsed time of t seconds even after the second fire alarm according to the second detection signal is output, and to stop extinguishing gas by stopping the air conditioning system and operating the automatic fire extinguishing unit after this time elapses.

By this control method, the sensitivity of the fire detection is increased so that a rapid fire alarm is output and the fire alarm is output according to the detection level in each step to prevent the error of the fire detection and finally the elapsed time before the automatic fire extinguishing system is operated. It is possible to stop fire alarms due to errors or to switch to manual fire extinguishing systems as necessary.

In addition, if the manual fire extinguishing system is required to extinguish a local fire after the fire alarm output, if a person in the room presses the manual fire extinguishing switch, the air conditioner is stopped after t seconds and the solenoid valve of the manual fire extinguishing unit is An open person can take the fire hose to where it is needed to extinguish the fire.

In addition, in the air conditioner provided with the fire extinguishing system of the present invention, in order to increase the accuracy of the fire detection, a method of generating a fire alarm when the room temperature rises sharply even when the room temperature is lower than or equal to the fire generation set temperature is used. That is, when a fire occurs, the temperature rises sharply, and when the rising rate of the detected temperature rises rapidly even under the set fire temperature, a fire alarm is generated.

6 is a flowchart illustrating an embodiment of the above-described control method. As shown in FIG. 6, when the temperature detected by the temperature sensor reaches a fire occurrence set temperature, a fire alarm is generated, and even when the temperature is lower than the set temperature, a short term temperature rise rate is calculated to generate a fire alarm when the temperature rise rate is higher than the standard rise rate. To stop the air conditioner operation and extinguish the fire by the fire extinguishing system of the present invention. At this time, the temperature rise rate is calculated for each reference time interval (second unit) below the set temperature and compared with the standard rise rate, the standard rise rate determines the temperature rise rate that can be determined as a fire.

In addition, in the present invention, as another control method for preventing unnecessary injection of extinguishing gas or extinguishing liquid due to errors and malfunctions, the rise time of the room temperature even when the room temperature reaches a set fire temperature due to fire or other heat. By checking, it is possible to use a method of generating a fire alarm by recognizing a fire only when the temperature rises sharply.

In other words, the room temperature can be increased not only by the fire but also by other factors. In general, the temperature increase due to the fire occurs rapidly, while the temperature rise due to other factors than the fire (e.g. radiant heat due to mining or heating) gradually increases. When the indoor temperature reaches the reference (set) temperature, the temperature rise time from the initial indoor temperature to the set fire temperature is calculated by using the characteristics made, and the fire alarm is generated only when the reference time is less than the reference time. In addition, a fire alarm may be generated only when the temperature rise time is instead of the standard rise rate by calculating the average temperature rise rate at the initial temperature and the set fire temperature range.

7 is a flowchart illustrating the above-described control method. First, the temperature sensor of the fire detection unit detects the initial temperature of the room, and then sets the indoor temperature as the reference temperature (the minimum temperature at the time of fire occurrence) as the reference temperature according to a specific factor. Control unit calculates the rise time or temperature rise rate from the initial temperature to the reference temperature and compares it with the reference time (preferably the minimum temperature rise time is set as the reference time when a fire occurs) or the standard rise rate. In case of the rise time, the fire alarm is generated only when it is below the reference time or when the temperature rise rate is above the base rise rate.

The above-described control methods may be applied to each or together, and by this control method, the present invention can quickly detect a fire and operate a fire extinguishing system, while minimizing the occurrence of an alarm due to a fire detection error and a malfunction.

Hereinafter will be described an operation example of the air conditioner with a fire extinguishing system of the present invention. When the primary detection signal is input from the fire detection unit unit including the heat or smoke detection sensor, the control unit fires the fire alarm through the fire alarm unit unit including buzzers 16 and 24 or alarm lamps 17 and 26 to the indoor unit or the outdoor unit. Outputs If the secondary detection signal is input after the primary fire alarm, the control unit outputs the secondary alarm through the fire alarm unit. In the second alarm, the lighting lamp 72 is turned on and the laser is output from the laser alarm lamp 28 to illuminate the entrance and exit. Pressing the release switch stops the alarm lamp and the buzzer to stop the fire extinguishing system. When t seconds have elapsed after the output of the second fire alarm, the air conditioning system is stopped and the solenoid valve of the automatic fire extinguishing unit is opened to extinguish the fire by releasing extinguishing gas through the automatic fire extinguishing nozzle.

In addition, if it is necessary to extinguish a fire manually for local fire extinguishing before the automatic fire extinguishing system is operated, the air conditioning system is stopped when a person in the room presses the manual fire extinguishing switch 35, and if the fire alarm unit If the alarm signal is not output from the unit, the buzzers 16 and 24 installed in the indoor unit and the outdoor unit, the alarm lamps 17 and 26, and the laser alarm lamp 28 operate. In addition, when the manual fire switch 35 is pressed and the door 27 of the air conditioner is automatically opened, the internal fire hose is taken out and the nozzle is aimed at the place where the fire has occurred. As it is opened, the extinguishing gas is released and converted to a pressure that can be injected by a person while passing through the pressure control valves 80 and 81, and the extinguishing gas is injected through the manual fire nozzle 208 to the aimed position. When the fire extinguishing is completed and the emergency stop switch 25 is pressed, the buzzer 16 and 24 and the alarm lamps 17 and 26 stop the laser alarm lamp 28 and the solenoid valves 12 and 7 close to extinguish the gas. It doesn't work. The air conditioning system is restarted using the air conditioner operation switch 101.
