Description

{VENTILATION SYSTEM AND METHOD}

The present invention relates to an indoor ventilation system, and provides an indoor ventilation system that can perform ventilation using outside air in conjunction with an air conditioner in a facility.

It is necessary to introduce fresh outside air to maintain a pleasant environment of the indoor space. It is most effective to purge the air in the room by introducing clean air from the outside.

Therefore, the introduction of adequate outside air is an important factor in maintaining the pleasant environment of the facilities (buildings, vehicles, railroad, subway, ships, etc.).

However, in recent years, due to pollution such as dust and fine dust, simply introducing outside air to ventilate a facility is a problem of polluting the inside air.

(Patent Document 1) Korean Patent No. 10-0652146 (Patent Document 2) Korean Patent No. 10-1227319 (Patent Document 3) Korean Registered Utility Model No. 20-0355652

It is necessary to use the ambient air enthalpy control method for the energy saving of the facilities. However, introduction of outside air into the room due to outside air pollution such as fine dust and dust is increasingly polluting the inside of the facility.

Particularly, fine dust is dust having a diameter of 10 μm or less and is mainly discharged through automobile exhaust gas or factory chimney. It also refers to small dust that enters China when yellow dust or severe smog occurs in China. The smaller fine dust particles in the fine dust are referred to as ultrafine dust particles and the dusts having a diameter of 2.5 μm or less are referred to. Such fine dust / ultrafine dust penetrates deep into the respiratory tract such as the lungs of the lungs and enters the blood vessels and causes a lot of diseases. Exposure to fine dusts for a long time may cause a rapid decrease in immunity and exposure to various diseases such as cardiovascular diseases, skin diseases and eye diseases as well as respiratory diseases such as colds, asthma and bronchitis. Fine dust management in facilities is essential.

The facility 100 according to the present embodiment can be used not only for buildings such as apartments, buildings, tunnels, but also for buildings such as cars, railways, ships and subways to block outside air, Lt; / RTI > Preferably, the structure has at least one internal space.

The environment of the inside and outside air managed in this embodiment includes temperature, humidity and fine dust. In addition, carbon dioxide may be measured to measure turbidity, but not limited thereto, various air quality measurement values may be used depending on the use environment and conditions.

The internal air measurement unit 200 includes an internal CO ₂ sensor 210 for measuring the concentration of carbon dioxide in the internal air, an internal temperature sensor 220 for measuring the internal air temperature, an internal humidity sensor And an internal fine dust sensor 240 for measuring the fine dust concentration of the inside air.

Of course, sensors of the internal air measuring unit 200 may be directly connected to the air conditioning control unit 500 to transmit information.

The internal CO ₂ sensor 210, the internal temperature sensor 220, the internal humidity sensor 230, and the internal fine dust sensor 240 are preferably provided in one modular form. Of course, they may be mounted on a control panel for controlling the air conditioner 400. However, the present invention is not limited thereto and may be installed in the internal space of the facility 100. Such a sensor may be installed with one to several tens or several hundreds of sensors according to the shape and structure of the internal space of the facility 100.

The external air measuring unit 300 includes an external temperature sensor 310 for measuring the temperature of the external air, an external humidity sensor 320 for measuring the humidity of the external air, an external fine dust And includes a measurement sensor unit 330, 2000.

Although not shown, the external air measurement unit 300 may further include a signal transmission unit for collecting the sensing results of the sensors and transmitting the sensing results to the air conditioning control unit.

It is effective that the external air measuring unit 300 of the present embodiment is installed on the outer wall of the facility 100. Preferably, the air conditioner 400 of the facility 100 is installed in a region where air is introduced. This allows real-time sensing of incoming air environmental conditions.

The air conditioning apparatus 400 includes a damper unit 410 for introducing outside air, an air purifying unit 420 for purifying the air, an air heating unit 430 for heating the air, an air cooling unit A blowing duct 450 for conveying the purified, heated or cooled air to the internal space of the facility 100, and a blower 460 disposed at the end of the blowing duct 450 to send out air . The external air can be introduced into the internal space of the facility 100 and the temperature and humidity of the internal space can be kept constant.

The damper unit 410 inflows outside air or blocks inflow according to the control signal of the air conditioning control unit 500. [ Of course, although not shown, a filter may be installed in the damper unit 410 to control the fine dust amount of the external air. In addition, the damper unit 410 includes a main damper of a large size and a sub damper of a small size, so that the amount of introduced air can be precisely adjusted.

The air purifier 420 is preferably provided with a plurality of filters, and purifies the indoor air through the filters.

It is preferable that the air heating unit 430 heats the inflow air through a separate heating unit or heats the circulated air in the room. It is also possible to use a coil as the heating unit.

The air cooling unit 440 preferably cools the inflow air or the indoor circulation air using a cooling device.

As described above, a separate outdoor unit may be provided for air heating or cooling. Also, although not shown, the air heating unit 430 and the air cooling unit 440 may be configured through a single cooling / heating unit.

Preferably, the blast duct 450 extends like a mesh within the interior space of the facility 100. The air passing through the air purifying unit 420, the air heating unit 430, and the air cooling unit 440 through the air blowing duct 450 maintains the proper temperature and humidity.

The blower 460 supplies the air provided through the blowing duct 450 to the indoor space so that the temperature and the humidity of the indoor space can be maintained constant.

The air conditioner of this embodiment is not limited to the above-described configuration, and various configurations are possible.

The air conditioner (400) operates according to the control signal of the air conditioning control unit (500).

The air conditioning control unit 500 includes an information reception unit 510 for receiving information from the internal air measurement unit 200 and the external air measurement unit 300, And an outside air inflow control unit 530 for controlling inflow of outside air using the received information.

The information receiving unit 510 receives and stores the carbon dioxide concentration, the air temperature, the air humidity, and the fine dust amount in the inside air from the inside air measuring unit 200. Also, the outdoor air measurement unit 300 receives the temperature, humidity, and fine dust amount of the outside air and stores the received data. Then, the provided information is provided to the betting control unit 520 and the outside air inflow control unit 530.

The information reception unit 510 amplifies or modifies the provided information and provides information required by the other control unit. In addition, the provided information can be provided at predetermined intervals or in real time.

The air pollution control unit 520 adjusts the air conditioning apparatus 400 so that the internal air is adjusted to the set environment by using the internal air environment information measured from the internal air measurement unit 200.

For example, when the temperature of the inside air is lower than the set temperature, the air heating unit 430 of the air conditioner 400 is operated to heat the air. On the contrary, when the temperature of the internal air is higher than the set temperature, the air cooling unit 440 of the air conditioner 400 is operated to cool the air. Humidity can also be adjusted in this way.

If the amount of carbon dioxide in the inside air and the amount of fine dust are excessive, the outside air inflow control unit 530 may be requested to inflow outside air.

The ambient air inflow control unit 530 analyzes the fine dust amount of the outside air, analyzes the carbon dioxide concentration and fine dust amount of the inside air, analyzes the temperature difference between the outside air and the inside air, and controls the air conditioner And controls the inflow amount of outside air.

Classify the amount of fine dust in the outside air into five levels.

The case where the fine dust concentration is in the range of 0 to 30 占 퐂 / m3 占 day is referred to as one step, the case of 31 to 80 占 퐂 / In the range of 121 to 200 占 퐂 / m3 占 day in four steps and in the case of more than 200 占 퐂 / m3 占 day in five steps.

In this manner, the outdoor air flowing into each of the classification stages is controlled. In the case where the outdoor air quantity capable of introducing the air conditioner is set to 100, the first stage is set to flow 0 to 100%, the second stage is set to flow 0 to 80%, the third stage is set to flow 0 to 50% , The fourth step is set to flow 0 to 20%, and the fifth step is set to flow 0 to 10%.

The temperature difference between the outside air and the inside air is also classified into five levels.

The case where the temperature difference between the air and the air is in the range of 0 to 20% is set as one step, the case where the range is between 21 and 40% is set as the two-step, the case where the temperature difference is between 41 and 60% , And the case of 80% or more is defined as 5 steps.

If the air conditioner capable of introducing the air conditioner is set to 100, it is set to be 100% inflow in the first stage, 80% inflow in the second stage, 50% inflow in the third stage, 20% inflow in the fourth stage, To 10%.

The enthalpy control of the amount of external air introduced by using the difference between the amount of fine dust of the outside air and the temperature difference between the inside and the outside air facilitates the ventilation of the inside air and maximizes the efficiency of the entire air conditioning system.

When the temperature difference is minimum with a small amount of fine dust, the flow rate can be maximized. If there is a lot of fine dust, the amount of inflow can be made small even if the temperature difference is small.

Of course, the inflow operation can be controlled by the amount of carbon dioxide and the amount of fine dust in the inside air. In the present embodiment, it is preferable that external air is not introduced when the fine dust amount of the outside air is in the 4th and 5th stages irrespective of the temperature difference between the inside air and the outside air. However, when the amount of carbon dioxide in the internal air is 6000 ppm or more even under such a condition, it is possible to carry out forced inflow to the outside air equivalent to the first or second stage (based on fine dust amount). When the amount of carbon dioxide is in the range of 2000 to 5999 ppm, the first to fourth steps are activated based on the amount of fine dust to allow the outside air to flow. When the amount of carbon dioxide is less than the above range, it is preferable that steps 4 and 5 are not operated as mentioned above.

This is because it is necessary to refrain from outdoor activities for a long time if the amount of fine dust of the outside air is in the third level. In step 4, it is required to refrain from excessive outdoor activities and especially to refrain from external activities for respiratory, heart, do. In addition, the 5th step is to limit the outdoor activity itself, and only to indoor activities. This is because damage due to fine dust may occur.

However, when the concentration of carbon dioxide in the inside air becomes high, ventilation to the inside air is indispensably required.

An example of the operation of the outside air inflow control unit 530 of the air conditioning control unit 500 will be described below.

If the amount of fine dust in the outside air is 2, and the temperature difference between the inside air and the outside air is 3, it is preferable to introduce the outside air only 40% (50% of 80%) of the maximum inflow amount.

The outside air inflow control unit 530 can control the outside air introduction by analyzing the residence time of the user in the building. In other words, in case of office building, ventilation can be carried out by introducing outside air at the early morning time, and after that, ventilation work can be carried out under the above conditions. Of course, in this case, the outside air inflow control section may perform this operation in accordance with the control signal of the manager.

In the following, a method of ventilating an indoor space of a facility having the above-described structure will be described with reference to the drawings.

6 is a flowchart illustrating an indoor ventilation method according to an embodiment of the present invention.

6, the temperature of the internal air, the amount of fine dust, and the concentration of carbon dioxide are measured, and the amount of fine dust and temperature of the outside air are measured (S110, S120).

The amount of outside air introduced according to the fine dust amount of outside air is firstly determined (S130).

The temperature difference between the outside air and the inside air is analyzed, and the amount of outside air introduced by the temperature difference is secondarily determined (S140).

When the concentration of carbon dioxide in the inside air is below the reference range, the amount of outside air introduced is multiplied by the first determination value and the second determination value (S150)

When the carbon dioxide concentration exceeds the maximum value of the reference range, the outside air is introduced at the value of the introduction maximum value.

In addition, the present invention is equipped with a system for detecting an external dust concentration and displaying an alarm signal when it is above a reference level, and outputting an alarm signal. That is, it is possible to recognize the concentration of the external fine dust from the outside.

For this purpose, dust is detected through the external fine dust measuring sensor units 330 and 2000, and when dust above a reference level is detected, an alarm signal is outputted to induce the persons present in the dust zone to move out of the dust zone at a high speed .

The data measured by the external fine dust measuring sensor unit 2000 is transmitted to the controller 3000, and the controller 3000 displays the data measured by the dust measuring unit on the display 4000.

The external fine dust measuring sensor unit 2000 of the present invention includes an infrared transmitting means A for emitting infrared rays and a light receiving means for receiving light emitted from the infrared transmitting means and located opposite to the infrared transmitting means, (B) for controlling the input voltage of the infrared transmitting means (A) to increase when the output voltage of the infrared receiving means (B) is smaller than a set value, And a dust measurement control unit (C).

The infrared transmitting unit A receives the infrared transmitting control signal from the dust measuring control unit C, determines the infrared transmitting amount, and outputs the changed infrared transmitting amount.

That is, when the result of the infrared ray receiving means B is transmitted to the dust measurement control section C, the dust measurement control section C predicts the dust generation amount based on the data of the infrared ray receiving means B, And outputs a control signal to the infrared ray transmitting means (A) to adjust the infrared ray transmission amount to induce the output.

That is, the light amount data outputted from the infrared ray receiving means is read by the dust measurement control unit, and the light amount of the infrared light emitting means is automatically controlled based on the read light amount data, so that the sensitivity adjustment is automatically maintained constant. So that the measurement can be performed while maintaining the sensitivity state.

In other words, the dust measurement control section C determines that the degree of contamination is high when the amount of received light of the infrared ray receiving means B is low, and outputs a control signal to increase the light amount of the infrared ray transmitting means A If the amount of light received by the infrared ray receiving means C is too high, a contamination-free state or a precise measurement becomes difficult. Therefore, a control signal is outputted so as to lower the light amount of the infrared ray transmitting means A That is, it is necessary to keep the amount of infrared transmission light in an appropriate state. The infrared ray amount measured through the infrared ray receiving means is accurate and the dust amount can be more precisely predicted. Therefore, the dust amount data measured by the dust measurement control unit of the present invention can output the dust measurement result with high reliability.

In the present invention, when the dust measurement control unit C outputs a control signal in order to facilitate the change of the light amount of the infrared ray transmission unit, the transmission control unit 1 recognizes the control signal and drives the infrared ray transmitter conversion unit to perform the most appropriate infrared ray transmission .

The infrared transmitter converting means 2 includes a plurality of moving electromagnets 2a, 2b and 2c which are wound around the actuator 3 and are mounted with a predetermined distance therebetween and fixed to a position adjacent to the moving electromagnets 2a, 2b and 2c And a plurality of stationary electromagnets 2d, 2e, 2f to be installed,

When a signal from the transmission control section 1 is applied, current flows through the floating electromagnets 2a, 2b, 2c and the fixed electromagnets 2d, 2e, 2f to form magnetic poles , 2c and the fixed electromagnets 2d, 2e, 2f to generate the repulsive force and attracting force to drive the actuator 3.

The actuator 3 is provided with a plurality of concave lens groups for limiting the infrared ray output by the flow of the infrared transmitter converting means 2.

It is needless to say that the number of the fitting holes 6a and the weight adjusting pins 6b may be varied according to need. In the embodiment of the present invention, three fitting holes 6a and three weight adjusting pins 6b ), So that the explanation can be made more convenient.

In addition, according to the present invention, when dust is detected as a reference or more and a notification situation occurs, the control unit 3000 displays the notification status through the automatic communication signal output unit 1000 and prompts the user to solve the problem quickly, The first switching transistor sw1 and the second switching transistor sw2 are connected in parallel to the power supply line 1110. The power supply unit 1110 includes a power supply unit 1110, a first switching transistor, a second switching transistor, a third switching transistor, a fourth switching transistor, A second circuit connection switch (sw2), and a communication control section (1120).

The power source unit 1110 applies power to its own power source.

The first switching transistor Q1 switches the circuit according to a switching signal input to the base.

The second switching transistor Q2 operates in accordance with the operation of the first switching transistor and switches the power source output from the power source unit.

The third switching transistor Q3 switches the circuit according to a switching signal input to the base.

The fourth switching transistor Q4 is provided on the other side of the output terminal of the power supply unit to switch the power supply unit output from the power supply unit.

The relay switch RL1 is coupled to the output terminal of the fourth switching transistor and generates a magnetic force when the fourth switching transistor is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The second communication signal output power switch sw2 serves to induce a communication signal to be output through the communication signal output unit 1150 by supplying power to the communication signal output control unit 1140 while the iron wire is pulled by the relay switch do.

The communication controller 1120 switches the third switching transistor and the fourth switching transistor to switch the relay switch so that the first circuit connection switch and the second communication signal output power switch are switched, A first circuit connection switch configured to switch the first switching transistor and the second switching transistor while turning off the switching transistor and the fourth switching transistor and to turn off the relay switch and simultaneously to be interlocked with the first switching transistor and the second switching transistor And maintains the communication state by continuing the switching state of the second communication signal output power switch.

In addition, the present invention is characterized in that it comprises a circuit board 1131 for operation, a wire piece 1132 for connection to a power supply for operating a communication signal control unit, a first resilient holding means 1133, a second resilient holding means 1134, (1133a), and a manual operation switch (1135).

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 and relays the power delivered from the second switching transistor to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first elastic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 so that the first circuit connection switch sw1 and the circuit operation wire 1131 are always kept in the off state when the relay switch is not operated .

The second elastic holding means 1134 is installed on the upper portion of the first circuit connecting switch sw1 and is spaced apart from the first elastic holding means by a predetermined distance. When the relay switch is operated, the circuit breaker 1131 is pulled to be coupled with the first resilient holding means 1133 while the first resilient holding means is overlapped, and at the same time, the first circuit connecting switch sw1 is switched So that even if the operation of the relay switch is stopped, the state of attaching the circuit breaker 1131 continues to maintain the power supply state through the first switching transistor and the second switching transistor. At this time, when the circuit breaker 1131 is operated by the operation of the relay switch, the communication piece 1132 is automatically operated to output the communication signal to the outside.

The gap maintaining means 1133a guides the second elastic holding means 1134 and the first elastic holding means 1133 to be engaged with each other while maintaining a constant gap without being directly coupled to each other when the first elastic holding means 1134 and the first elastic holding means 1133 are engaged, 1133 and the second resilient holding means 1134 can be more smoothly separated from each other by the action of the gap maintaining means at the time of disassembly. If the gap maintaining means is not present, the first elastic holding means 1133 and the second elastic holding means 1134 are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, the first elastic holding means 1133 and the second elastic holding means 1134 can be easily separated by further providing the gap holding means 1133a.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a communication signal output control unit. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, a power is applied to the third switching transistor and the fourth switching transistor to operate the relay switch RL1. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch sw1 is operated, the control unit interrupts the operation of the third switching transistor and the fourth switching transistor to cut off the operation of the relay switch, and simultaneously operates the first switching transistor and the second switching transistor.

On the other hand, if the operator turns off the first circuit connecting switch and the communication signal output power switch in the middle of outputting the communication signal, the control unit recognizes this, and then the third switching transistor and the fourth switching transistor are operated, It is possible to keep the closed circuit while moving the iron piece and at the same time return the power outputted to the communication signal control part 1140 to continuously operate the communication signal output part 1150.

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when a switching signal is applied to the third switching transistor, the fourth switching transistor, the first switching transistor, and the second switching transistor in the control unit, the communication signal is automatically output by returning the power source again, It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output a communication signal, the control unit no longer applies a power supply signal to the first switching transistor, the second switching transistor, the third switching transistor, and the fourth switching transistor. ) Can be manually operated by a user to interrupt the communication signal.
