Description

Smoke control system for living room}

The present invention relates to a living room ventilation system, and more particularly, to a living room ventilation system for controlling the opening and closing operation of a damper installed in a ventilation area or a ventilation area and controlling the amount of air supplied to the ventilation area for ventilation of the living room.

In the living room ventilation system, when a fire alarm sounds in a fire room (hereinafter referred to as a ventilation area) where a fire occurs, fresh air is supplied by operating a supply air blower connected to the supply air duct installed at the lower part of the ventilation boundary of the ventilation area. The fire smoke is discharged with an exhaust blower connected to the exhaust duct installed in the building to delay the descent of the smoke layer, thereby avoiding the smoke and heat, helping the occupants safely evacuate and engage in fire fighting activities.

1 is an embodiment showing the configuration of a conventional living room ventilation system, in an air supply duct and an exhaust duct installed for at least one ventilation area (eg, A area, B area, etc.) in a building so as to open and close for ventilation of the living room. A ventilation damper (101,102,103,104,201,202,203,204,301,302,401,402) disposed, an air supply blower (C01) that controls the amount of air supplied to the ventilation area in case of fire, and an exhaust blower (C02) that controls the amount of exhaust from the ventilation area in case of fire. Includes.

In the conventional living room ventilation system configured as described above, the controller C04 operates the actuator C03 to control the ventilation damper in an open or closed state according to a predetermined schedule before and during a fire signal.

Conventional living room ventilation systems are becoming large or three-dimensional according to the high density, integration, and high rise of urban buildings.

For example, the components of the conventional living room ventilation system are various such as air conditioning equipment, ventilation equipment, equipment piping and fire extinguishing equipment piping, electrical equipment and wire trays, communication lines for communication, etc. between the half and ceiling of a building forming a large space. It is three-dimensionally arranged and installed with the facility.

Meanwhile, in architectural design, in order to reduce construction cost, the height between the half and the ceiling is minimized, and the main ducts for living room ventilation are mostly used for both air conditioning equipment and basin for the space arrangement and efficient use of facilities for occupants in the building. Ducts are installed for both air conditioning and living room ventilation or exclusively for living room ventilation, if necessary.

For example, in the conventional living room ventilation system as shown in Fig. 1, the main duct and branch duct of an air conditioning facility normally perform the function of air conditioning, but in case of a fire, the main duct for living room ventilation is combined with or installed in a dedicated branch duct. A damper (e.g., SMD, Smoke Motorized Damper) operates in an open or closed state according to a predetermined schedule to form a ventilation area, and a blower for supply and exhaust of an air conditioner is used for supply or exhaust. When the capacity of the blower installed in the air conditioner is insufficient or the purpose is not suitable, a separate air supply/exhaust blower for living room ventilation is installed and used in connection with fire in order to secure the function of ventilation in the living room.

On the other hand, when the new building is completed, the performance test procedure of living room ventilation is carried out as follows to check whether the ventilation area in the design document according to the national fire safety standard is confirmed, and then the supply and discharge quantity of each ventilation area is higher than the design performance. In order to check the status of the firefighting facility afterwards, legally, twice a year, whether or not the performance is properly maintained is carried out by a firefighting facility management professional company.

[Performance test procedure of living room ventilation]

1. Check the open or closed condition of the re-entrainment damper according to a predetermined schedule so that the air conditioning or ventilation system is appropriate in the normal condition where the fire signal does not sound.

2. A fire signal is given for each ventilation area to determine whether air supply or exhaust is supplied only to the ventilation area given the fire signal. And check that there is no supply and exhaust phenomenon in the exhaust mechanism.

3. Check whether the performance of the air supply and displacement for each ventilation zone where the fire signal is sounded is higher than the air volume set by the national fire safety standard.

4. After performing the above procedure for all ventilation areas for living room ventilation, after confirming that performance beyond the regulations of the National Fire Safety Standard is secured, a document must be prepared and reported to the fire department.

For reference, in the performance test of living room ventilation, identification of the ventilation dampers in the air supply and exhaust ducts constituting the ventilation area corresponding to the place where the fire occurred among the number of ventilation areas in the current one building or large underground shopping malls of a number of buildings. The operation according to the number is set to Normal Close or Normal Open, and when a fire signal sounds, it is opened only in the ventilation area where the fire signal is sent and according to the identification number of the ventilation damper in the exhaust duct. Or, determining the operation in a closed state is called a ventilation damper schedule or schedule list.

When performing the performance test of living room ventilation as described above, there are the following problems.

When performing the ventilation TAB (Testing, Adjusting and Balancing) before the completion of the firefighting of a new building, the condition of the ventilation damper before the fire signal is normally closed according to the ventilation damper schedule list (in order of damper identification number) under normal air conditioning conditions. Alternatively, check whether it is normally open, check whether the ventilation damper for the ventilation area is properly operated, and if the ventilation damper does not fit, check the identification number to ensure that all ventilation is operated in the open and closed conditions set for the ventilation damper. The dampers must be checked and corrected in order of number.

As such, when checking the operation of the ventilation damper by identification number, operate the blower to check the opening and closing status of the ventilation damper in the air-conditioning condition by placing a light sparkling thread at the entrance of the appliance to check the intake and discharge status, and ventilation that does not match the schedule list. As for the damper, the test operator must go up to half the position and find the ventilation damper of the corresponding identification number and change the operation setting or change the wiring. To complete this condition, the above operation must be repeated to confirm.

In this way, when checking the open and closed status of the ventilation damper according to the schedule list is completed, the task of checking the airflow by the identification number of the ventilation area and the surrounding ventilation dampers in the same way by giving a fire signal for each ventilation area is the whole building. It should be repeated until it has been confirmed that the demarcation of the control area for the is completed.

However, currently, only an operation signal is given so that the ventilation dampers of the supply and exhaust are operated in open and closed states in the order of identification numbers according to the schedule list in the fire signal transmission ventilation zone.

Therefore, when checking the performance of ventilation in the living room, check the operation status of the ventilation damper according to the schedule list before the fire signal according to the schedule list (damper identification number order) and the operation status of the ventilation damper according to the schedule list in the case of a fire in the above usual air conditioning condition. There is a problem that must be performed repeatedly.

In addition, in the conventional living room ventilation system, it is not possible to grasp the operation state of the ventilation damper in the fire room, and it is impossible to control the ventilation damper in other ventilation zones when necessary.

In particular, checking the operation status of the ventilation damper according to the schedule list before the fire signal and in the event of a fire is performed in a space where multiple facilities are intersected and arranged in the dark where the ceiling is high and light is blocked in the case of a large underground shopping mall. It is very difficult and difficult to find the corresponding ventilation damper in the order of the identification number of the ventilation damper, and there are many cases where access is not possible depending on the composition of the space. If the floor height is high, it is often impossible to divide the ventilation area.

Before the above fire signal and after the work to check the operation status of the ventilation damper according to the schedule list in case of fire is completed, the air supply and exhaust volume of the national fire safety standard for each ventilation zone should be measured to check whether the performance is more than the legal design air volume. do.

Currently, in the environment described above, in the environment described above, the airflow volume for each ventilation area should be measured with a Pitot tube in the semi-automatic duct by setting the proper position of the straight pipe duct, but most of the conditions are practically impossible. The reality is that there is little. In addition, it is a reality that it is not possible to do, but there is a risk of work, although it is necessary to regularly perform comprehensive inspection and operation function check twice a year.

The living room ventilation system according to the present invention configured as described above operates as follows.

2 illustrates one floor of a building consisting of two ventilation zones A zone and B zone.

The air supply blower C01 of FIG. 2 supplies external air to the A and B regions constituting the ventilation zone through the air supply duct.

Ventilation dampers 101 and 102 are arranged in the branch air supply duct in Area A, and the open/close state of the ventilation dampers 101 and 102 is detected or the air current is detected by the air flow detectors a01 and a02, and the ventilation dampers 103 and 104 are arranged in the branch air supply duct in the B area. As a result, the open/close state of the ventilation dampers 103 and 104 is sensed by the air flow detectors b01 and b02, or airflow is sensed.

The ventilation damper 301 is arranged in the main air supply duct in A zone, and the open/closed state of the ventilation damper 301 is sensed by the air flow sensor a03 or the air current is detected, and the ventilation damper 302 is arranged in the main air supply duct in the B zone. An open/closed state of the ventilation damper 302 is sensed or an air current is sensed.

An air volume meter 501 is placed in the main air supply duct in A zone to measure the air supply volume in the air supply duct leading to the ventilation zone or the expected ventilation zone around the ventilation zone during the opening and closing operation of the ventilation damper, and the air volume meter in the main air supply duct in zone B. A 502 is arranged to measure the amount of air supplied from the air supply duct leading to the ventilation area or the expected ventilation area around the ventilation area during the opening and closing operation of the ventilation damper.

In the air supply blower C01 of FIG. 2, the air supply quantity measuring device 503 or 504 measures the supply air quantity in the intake duct or the discharge duct.

The exhaust blower C02 of FIG. 2 discharges internal air through an exhaust duct to a zone A and a zone B constituting a ventilation zone.

Ventilation dampers 201 and 202 are arranged in the branch exhaust ducts of area A, and the opening and closing status of the ventilation dampers 201 and 202 are detected by air flow detectors c01 and c02, or airflow is detected, and ventilation dampers 203 and 204 are arranged in the branch exhaust ducts of area B. As a result, the open/close state of the ventilation dampers 203 and 204 is sensed by the air flow detectors d01 and d02, or the airflow is sensed.

A ventilation damper 401 is arranged in the main exhaust duct of area A, and the open/closed state of the ventilation damper 401 is detected by the air flow sensor c03 or airflow is detected, and the ventilation damper 402 is arranged in the main exhaust duct of the B area, An open/closed state of the ventilation damper 402 is sensed or an air current is sensed.

An air volume meter 601 is arranged in the main exhaust duct of zone A to measure the exhaust volume from the exhaust duct leading to the ventilation zone or the expected ventilation zone around the ventilation damper during the opening and closing operation of the ventilation damper, and the air volume meter 602 in the main exhaust duct of zone B. Is arranged to measure the amount of exhaust from the exhaust duct leading to the ventilation area or the expected ventilation area around the ventilation area during the opening and closing operation of the ventilation damper.

The exhaust blower C02 of FIG. 2 measures an exhaust amount by an exhaust amount meter 603 or 604 in an intake duct or a discharge duct.

In Fig. 2, surveillance cameras 701 and 702 installed in two ventilation zones A and B respectively monitor smoke layer heights or smoke concentrations for each of the ventilation zones or expected ventilation zones around the ventilation zones.

Before or after a fire, the controller C04 communicates with the actuator C03 by wire or wirelessly according to a predetermined schedule (e.g., a pre-fire air conditioning schedule or a living room ventilation schedule after a fire). Each of the ventilation dampers installed in the expected ventilation area of is opened and closed, and the open/closed state is displayed on the display device C03' for each damper identification number.

In the case of Fig. 2, each of the ventilation dampers installed in the ventilation zones A and B is controlled by the controller C04.

At this time, the controller C04 warns of a fault check for the ventilation damper indicating an opening/closing operation state inconsistent with the schedule based on the opening/closing signal transmitted via the actuator C03 or the airflow detection signal. And it automatically controls the opening/closing operation of the replay damper to match the above schedule.

For example, in case of fire, when 101 of the ventilation dampers 101, 102, and 301 installed in the ventilation zone A of FIG. 2 must be in an open state according to a schedule in case of fire, but is displayed in a closed state, the controller C04 ) Automatically controls the ventilation damper 101 from the closed state to the open state.

At this time, the open/close signal is distinguished by an open signal or a close signal, and the controller C04 does not receive the airflow detection signal while receiving the open signal via the driver C03, or the closing signal. When the airflow detection signal is received in a state in which the signal is received, a fault check is alerted to a ventilation damper indicating an opening/closing operation state that is inconsistent with the schedule described above, for example 101 described above.

At this time, the controller C04 may control the opening/closing operation of each ventilation damper according to the change command regardless of a predetermined schedule when a command to change the opening/closing operation of the system manager for each of the ventilation dampers is input.

For example, in the event of a fire, 101 of the ventilation dampers 101, 102, and 301 installed in the ventilation area A of FIG. 2 must be in an open state according to a schedule in case of a fire. Accordingly, when the closed state is not automatically changed from the closed state to the open state, the controller C04 controls the ventilation damper 101 from the closed state to the open state in response to an opening/closing operation change command of the system manager.

Accordingly, the controller (C04) can easily correct the abnormal operation state of the ventilation damper to the normal operation state by warning of a fault check for the ventilation damper as to whether each of the ventilation dampers is normally open/closed, and quick maintenance when a failure occurs. Through maintenance, the operating state of the system can be stably maintained.

On the other hand, in the event of a fire, the controller C04 communicates with the actuator C03 by wire or wirelessly, based on the amount of air supply or exhaust measured by the air flow meter 501,502,601,602, or based on the supply air volume meter 503,504 or the displacement meter ( 603,604) by driving the air supply air volume variable (C01') or the exhaust air volume variable (C02') based on the air supply volume or exhaust volume measured by the air supply fan (C01) to determine the air supply volume of the air supply fan (C01) or the exhaust volume of the exhaust fan (C02). It is controlled by the automatically set air volume.

For example, in the event of a fire, based on the air supply amount measured by the air volume meter 501 arranged in the main air supply duct in the A zone of FIG. 2 or the air volume measuring instrument 502 arranged in the main air supply duct in the B zone, or the suction of the air supply fan (C01) The supply air quantity of the air supply fan C01 is automatically controlled by driving the air supply air quantity variable C01' based on the air supply quantity measured by the air supply air quantity measuring device 503 or 504 arranged in the duct or the discharge duct.

At this time, if the system administrator inputs a manual change command for the supply air volume of the air supply blower C01 or the exhaust air volume of the exhaust blower C02, the controller C04 returns the air supply air volume variable (C01') or the exhaust air volume. The toilet C02' is driven to control the air supply amount of the air supply blower or the exhaust amount of the exhaust air blower with a manually set air volume.

In this way, if the controller (C04) easily controls the operation of the air supply fan (C01) or the exhaust fan (C02) based on the measured supply air volume or exhaust volume in the event of a fire, it is possible to stably maintain the set air volume required for ventilation in the living room in the ventilation area. have.

The controller (C04) compares the supply or exhaust amount of the ventilation zone measured by the air flow meter (501,502,601,602) with the supply or exhaust volume measured by the supply air flow meter (503,504) or the exhaust flow meter (603,604). It is to determine whether the overall ventilation area of the building or the appropriateness of the leakage amount for each ventilation area, or whether the ventilation dampers arranged in the ventilation area operate appropriately.

For example, if a fire occurs in area A of FIG. 2 to form a current ventilation area, and assuming that it is an expected ventilation area in which no fire has occurred in area B, the airflow meter 501 disposed in the main supply air duct of area A is the ventilation damper 101, During the opening/closing operation of 102, 301, the air supply volume measured in the ventilation zone A zone 502 is the air flow measuring instrument 502 arranged in the main air supply duct in zone B, the air supply measured in the ventilation zone B zone during the opening and closing operation of the ventilation dampers 103, 104, 302. When compared with the air supply amount measured by the intake duct of the air supply blower C01 or the air supply quantity measuring device 503 or 504 disposed in the discharge duct, the supply air amount of the supply air blower C01 is present. It is normal if air is supplied to the ventilation zone A, and the air is not supplied to the expected ventilation zone B, not the current fire room.

However, the air volume meter 502 measured during the opening and closing operation of the ventilation dampers 103, 104, and 302 in the expected ventilation zone B, not the current fire room, is determined to be greater than the supply air volume to the current fire room, zone A, or more than the specified reference value. If so, it can be determined that leakage of more than the reference value has occurred in the expected ventilation zone B, or that one or more or all of the ventilation dampers 103, 104, and 302 arranged in the B zone are malfunctioning or malfunctioning.

In this way, by comparing the amount of air supply or exhaust to the ventilation area with the supply or exhaust amount of the air supply fan (C01) or the exhaust fan (C02), the appropriateness of the leakage amount of the entire ventilation area or each ventilation area of the building, or the ventilation damper disposed in the ventilation area. It is easy to determine whether the operation is appropriate.

The controller (C04) communicates with the actuator (C03) by wire or wirelessly to display the internal situation of the ventilation area photographed by the monitoring cameras (701, 702) or the internal situation of the expected ventilation area around the ventilation area on the display device (C03'). do.

For example, while the surveillance camera 701 in the ventilation zone A, which is the current fire room in FIG. 2, monitors the smoke layer height or smoke concentration, and the surveillance camera 702 in the predicted ventilation zone B, which is not the current fire room, monitors the internal situation, the system If smoke penetration is monitored by the administrator in the expected ventilation zone B, the controller (C04) operates the opening and closing operation of each ventilation damper and the air supply fan according to the system administrator's command to change the opening and closing operation, regardless of the schedule set in the expected ventilation zone B. Timely control of the air supply or exhaust volume of the (C01) or exhaust fan (C02) can control the spread of smoke or fire in zone B of the expected ventilation zone.
