Description

{Indoor Ventilation System Using a Corridor and Cracks}

The present invention relates to an indoor ventilation system, and more particularly, to an automatic ventilation management system capable of minimizing indoor energy loss.

Indoor air pollution in schools, apartments and underground shopping malls in Korea is serious. In addition, there is a large amount of airborne dust in the indoor air depending on indoor activities, and the fine dust in China affects the air pollution in the indoor air. Other contaminants that reduce indoor air quality include carbon dioxide, carbon monoxide, nitrogen dioxide, bacteria, formaldehyde, volatile organic compounds, and organic aromatic compounds.

In addition, as the number of people in a certain area of a room increases, the concentration of carbon dioxide increases by the respiration of the people, so the room may feel discomfort when the carbon dioxide is over 3% and the respiratory distress symptom when the carbon dioxide is over 10%.

In particular, in the room such as a school room or an office, fine dust caused by the activities of the people causes eye or neck pain, as well as inhaled dust, which causes various respiratory diseases and lung diseases.

Therefore, the government has amended the 'School Health Act' in March 2006 to provide a pleasant environment for the students and staff in the growing period to promote the protection of health and streamlining school education. In this law, 21.6 CMH / , And as a result, the demand for ventilators for school classrooms is greatly increasing.

In addition, the recognition that indoor air of a conventional building is the object of management was insufficient, and temperature or air-conditioning-oriented temperature management was all. However, due to the increase of air pollutants and the lack of oxygen due to health problems, many techniques for purifying indoor air have been developed.

The ventilation changes the polluted air in the room into a pleasant air, and the indoor air (hereinafter referred to as "indoor air") changes in state due to human activity, combustion of fuel, generation of harmful substances, and the like. The cleanliness of air is judged by the air condition such as temperature and humidity, air current such as wind speed, wind direction, dust, carbon dioxide, carbon monoxide, nitrogen oxides, bacteria and other harmful substances such as concentration and smell. . Ventilation is intended to improve these air environments to meet human health and hygiene activities, to meet the needs for thermal environment creation, and to preserve building materials.

However, when the ventilation is performed or the ventilator is operated, air and heat are discharged together when the vent is discharged. That is, in order to keep the temperature of the indoor air at the proper temperature, since the indoor heat is discharged together with the odor, the boiler or the air conditioner must be driven continuously, resulting in a waste of power. More specifically, outdoor air (hereinafter, referred to as "outside air") flowing outdoors is not maintained at a proper temperature by a boiler or an air conditioner, so that when the outside air enters the room, During the winter season, the temperature of the inside air becomes lower than the proper temperature, and the user feels discomfort due to the temperature change. Therefore, in order to maintain the room temperature at an appropriate temperature, the boiler must be continuously operated during the winter season to raise the room temperature and the air conditioner must be continuously operated during the summer season to lower the room temperature, so that the boiler and the air conditioner must always be operated. There is a problem.

In addition, since a large amount of heat energy or cooling air is contained in the indoor air discharged to the outside for ventilation, when the amount of ventilation is increased, a lot of heat energy is inevitably discharged to the outside. Thus, the loss of heat energy There is a need to recover the heat energy contained in the indoor air discharged to the outside of the room.

In order to solve these problems, techniques have been proposed which can prevent sudden temperature changes when the outside air is introduced by exchanging heat between the inside and outside air, and reduce the load of the air conditioner.

Such conventional technology generally includes an all-pass heat exchanger having a honeycomb flow path to regulate the temperature of the outside air by allowing heat exchange between the inside and outside air flowing along the respective flow paths. The above-described prior art has a certain degree of heat exchange between the inside air and the outside air by conducting the heat of the inside air passing through the flow path of the total enthalpy heat exchanger and supplying it to the outside air. However, since the total air heat exchanger merely provides a flow path for the inside air and the outside air Since the efficiency is lowered, the discomfort is left intact when the outside air is introduced, and there is a limit in reducing the load of the air conditioner.

According to the present invention, there is provided a technology for an energy saving ventilation automatic system capable of introducing clean air while minimizing internal energy loss.

Next, a brief description will be given of the prior arts existing in the field to which the technology of the present invention belongs, and the technical matters to be differentiated from the prior arts of the present invention will be described.

Therefore, a ventilation heat recovery apparatus capable of reducing the cost due to the operation of the air conditioner has been disclosed (Patent Document 01).

Korean Patent No. 10-1569270 (Apr. 11, 2015) discloses an indoor radon remover having an air purifier, specifically, an air purifier that removes contaminants and generates oxygen, and exhausts polluted air to the outside The present invention relates to an indoor radon remover capable of maintaining the indoor air concentration of the room to be maintained at a predetermined value by supplementing oxygen insufficient in a room such as a classroom.

However, in the ventilator including the air purifier proposed in the above-mentioned Patent Document 2, when the filter included in the air purifier is neglected, bacterial growth such as bacteria, fungi, and pollen, dust, and dust are adhered to cause atopy or asthma There is a concern. There is a problem in that the heat loss is considerable due to the sudden temperature difference between the inside air and the outside air in the method of performing the heat exchange with the clean outside air flowing in the phase-changed heat exchange medium by the discharged heat of the contaminated inside air.

According to the present invention, there is provided a technology for an indoor ventilation system capable of minimizing thermal energy loss in a room having a hallway.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

In addition, since the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It is to be understood that equivalents and modifications are possible.

Hereinafter, an indoor ventilation system using a corridor air including a demand control system according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining an indoor ventilation system using corridor air installed in a classroom equipped with a corridor according to an embodiment of the present invention.

As shown in FIG. 1, the indoor ventilation system using the corridor air is installed in a room provided with a corridor, and the indoor ventilation system using the corridor air sucks outside air in the corridor, An external air inflow part 100 for supplying air into the room; An inner air discharge unit 200 for discharging the contaminated inner air to the outside; A sensor unit 300; And a central control unit 400 connected to the sensor unit.

The indoor ventilation system is a system in which a measured value detected by the sensor unit 300 is transmitted to the central control unit and is controlled by the central control unit so that the external air inflow part 100 and the internal air exhaust part 200 are controlled Control system.

The sensor unit 300 may include a carbon dioxide sensor unit for detecting the concentration of carbon dioxide and a fine dust sensor unit for detecting the concentration of fine dust. The sensor unit installed on the inner wall or the ceiling of the room may include a carbon dioxide concentration and a fine dust concentration And transmits the measured value to the central control device 400.

The sensor unit may further include a radon sensor unit for detecting radon and a gas sensor unit for detecting gaseous pollutants.

When the concentration of the pollutant (fine dust, carbon dioxide, radon, or gaseous pollutant) received from the sensor unit 300 is equal to or greater than a predetermined value, the central control unit 400 controls the external air inflow part 100 and / When the concentration of the pollutant (fine dust, carbon dioxide, radon, or gaseous pollutant) is less than a predetermined value, the inner air exhausting unit 200 and the inner air exhausting unit 200 are operated, And stops the operation.

The external air inflow part 100 includes an external air inflow fan 110 for sucking outside air in the corridor, an external air supply pipe 120 for introducing external air introduced into the inflow fan, And an external air inlet pipe 130 installed in the external air supply pipe and introducing external air introduced into the external air supply pipe into the room.

The external air inlet fan 110 and the external air inlet switch may be controlled by the central controller 400. For example, when the concentration of carbon dioxide or fine dust measured by the sensor unit 300 is transmitted to the central control unit 400 and the measured value is greater than a predetermined value, The outdoor air inlet fan 110 starts to operate and the outside air in the hallway flows from the outdoor air inlet pipe 130 through the inlet fan 110 and the outdoor air supply pipe 120 to the indoor Lt; / RTI > On the other hand, when the measured value of the carbon dioxide or the fine dust transmitted to the central control device 400 is less than the predetermined value, the inlet switch installed in the outside air inlet portion 100 is changed to the closed type and the outside air inlet fan 110 ) Is stopped.

Preferably, the external air supply pipe 120 is connected to the inner wall or ceiling of the room, and one or more external air inlet pipes 130 are installed in the external air supply pipe. For example, as shown in FIG. 2, the external air supply pipe 120 is installed on a ceiling of a room over a predetermined length, and two or more external air inlet pipes 130 are provided in the external air supply pipe 120 So that the circulation of the outside air introduced into the room can be promoted.

In addition, it is preferable to include a dressing valve provided to selectively open / close the outside air inlet pipe 130, and the dressing valve may be controlled by the central control device 400. For example, when the concentration of carbon dioxide measured by the sensor unit 300 is equal to or greater than a predetermined value, the central control unit 400 executes the quick dressing mode and opens the dressing valves of all the external air inlet pipes 130, Air is quickly supplied to the entire room.

The internal air discharge fan 210 and the internal air discharge switch may be controlled by the central control device 400. For example, when the concentration of the pollutants (fine dust, carbon dioxide, radon or gaseous pollutants) detected by the sensor unit 300 is transmitted to the central control unit 400 and the measured value is greater than a predetermined value, The discharge switch installed inside the air discharge unit 200 is changed to an open type and the internal air discharge fan 210 starts to operate so that the inside air of the room flows through the discharge fan 210 and the internal air discharge pipe 220, And is discharged to the outside from the discharge tube (230). Conversely, when the concentration of the pollutants (fine dust, carbon dioxide, radon or gaseous pollutants) transmitted to the central control device 400 is less than a predetermined value, the discharge switch installed in the inside air discharge portion 200 is closed And the operation of the internal air discharge fan 110 is stopped.

When the measured value of the concentration of carbon dioxide and fine dust detected by the sensor unit is less than a predetermined value, the indoor ventilation system operates only the external air inflow part 100 without operating the internal air exhaust part 200, It provides the function of purifying the inside air. Specifically, a positive pressure is generated in the room due to the outside air introduced from the outside air inflow part 100, and the inside air in the room is automatically discharged through the inside air discharging part 200 due to the positive pressure formed in the room .

In addition, the indoor ventilation system may further include a second sensor unit for measuring a concentration of contaminants in the corridor, and the second sensor unit may include at least one concentration selected from the group of carbon dioxide, fine dust, radon, And a detection unit for detecting the signal.

When the concentration of the pollutants detected in the second sensor unit installed in the corridor exceeds a predetermined value, the indoor ventilation system operates only the internal air exhaust unit 200 without operating the external air inflow unit 100 And provides a function of purifying indoor air. Specifically, a negative pressure is generated in the room due to the internal air discharged from the internal air discharge unit 100, and external air in the hallway is automatically drawn in through the internal air inflow unit 200 due to the negative pressure formed in the room .

When the concentration of the pollutants (fine dust, carbon dioxide, radon, or gaseous pollutants) measured by the sensor unit installed in the indoor space exceeds a predetermined value, the indoor air ventilation system is connected to the indoor air exhaust unit 200, The air inlet 100 is simultaneously operated to purify the inside air of the room.
