Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an air conditioning method v'cl for buildings in air polluted areas.
Wj.

For example, areas near volcanoes that emit volcanic smoke, such as Sakurajima.
c, it is affected by the irregular VC-7 falling ash, regardless of its size. This falling ash dust has shapes ranging from fairly large particles to submicron-sized fumes, and it affects even the fine particles of tremo 11b. Buildings located in this area, such as manufacturing facilities such as high-end product production and processing factories, hinoki factories, or luxury hotels, are especially vulnerable to the intrusion of this falling ash dust. And the damage will be severe. In addition to this form of intrusion, the forced intake of air as air conditioning air f
Apart from this, ash dust can enter buildings through gaps in various parts of the building, or adhere to people, cars, luggage, etc. as they enter and exit the building, and take on various forms of IP4. If it gets into the interior, it is difficult to remove it, especially if it is in the form of fume, and it can have a negative impact on various types of equipment, reducing productivity and reducing production in the case of construction facilities. In particular, falling smoke ash, mountain pass water 1 (often accompanied by other corrosive substances, causing corrosion of @ type equipment, contact failure, poor insulation, bearing wear, rust, etc.) This causes RJ change 1 problems for chemicals, etc., and damages are already caused to the duct system, air conditioner 1, heat source water system, cooling tower 1, and other parts of the air conditioning equipment.

In some cases, this kind of damage is temporary, but in other areas it continues irregularly and semi-permanently, and it is necessary to construct an international-class hotel or a modern factory that requires high precision in these areas. However, drastic countermeasures against this ash fall are required, and the present invention has been made with this purpose in mind. It is an attempt to improve
Moreover, it is unique in that it has been systemized so that it can be carried out in an energy-saving manner.

The basic principle is to pressurize the building by controlling the amount of outside air that is forcibly taken in and the amount of exhaust air that is forcibly exhausted so that the internal pressure of the building is higher than the outside pressure. If the outside air pollution reaches a predetermined level from the monitoring device, the amount of r

The reason is that it is designed to lead to Vc.

Details of the pressurization control, air treatment for ash dust prevention, cleaning of contaminated air, etc. employed in the present invention will be explained in detail below according to the attached drawings.

j, l 5 no Izunotka1] Two or more types of rfX may be present singly or in combination.

Figure 5 shows the outside air construction applied to the pressurized air conditioning equipment of the present invention.
・Exhaust treatment device (compatible with Sit/C in Figure 2) is shown.

In this device, an air purifier 6 is installed in the outside air intake path from the outside air intake 2 to the air conditioner 1 so that it can be bypassed 12, an instruction signal VC of the outside air pollution sensor 7,! The outside air r1v is configured so that the inlet route can be switched between the route passing through the air purifier 6 and the bypass route 8, and the pressure difference between the inside and outside of the building 46) The pressure inside the building is higher than the outside pressure based on the instruction signal from the small device 9. In other words, it is configured to control the amount of exhaust gas discharged from the exhaust port 3. Each of the outside air path, supply air and return air path, and exhaust air path will be explained in detail.The amount of air flowing through these six paths is controlled to an appropriate amount by local control panels C and V'C. , the control system is designed to be comprehensively managed according to the degree of pollution of the outside air.

1. The outside air path is the path from the outside air intake 2 to the air conditioner 1.8 This path consists of a bypass path 8 and a passage through the air purification device 6.Which path does the outside air go through? Selecting which air to take in is selected by the signal VC from the outside air pollution sensor 7.
This switching is also carried out by using the electromagnetic turn bar 10 and 11 to distribute the amount of outside air. When the contamination is above a certain level, Vr,'d4° magnetic damper 10 closes and electromagnetic tamper 11 opens.

At the same time, the air purification device 6 is activated! 8 hours. This air purification device 6 consists of an electrostatic precipitator and an activated carbon composite filter, the electrostatic precipitator captures fine ash dust of 5μ or less that cannot be captured by ordinary filters, and the activated carbon composite filter captures So and other gas components. Inhale. When the ash fall is very strong, the VC is passed through a settling and removing device as shown in Fig. 4. What about this device i'4 eliminator 12 and afuku filter 16? The ash is vibrated by a vibration device h14, all of the collected ash is sieved off, received by a hopper 15, and stored in a dust collection bag 17 by a dust tamper 16π. The outside air pollution sensor 7 monitors whether the outside air condition is in a normal range, a dangerous range, or a dangerous range. As the ventilation ratio to the device 1 increases, the amount of outside air taken in by the air supply fan 20 is controlled to be as small as possible.For example, in the normal range, Outside air is taken in so that acid replenishment R[ is about 50 (m/flr/person), but it is 15 to 2 in the double precept area.
5 (m I (r people), n 15-10 (y
The amount of outside air (r) should be kept small so that the amount of oxygen supplemented by outside air (vc) is approximately 1/Hr/person). However, as will be described later, the displacement is correspondingly reduced (J: further).

The air supply and return air routes include air supply ducts 21 from the air conditioner 1 to CAV units or VAV units installed in various parts of the building, and 5V air returning to the air conditioner 1 from inlets at various parts of the building.
! (consists of air tact 22. W indicates humidifier). The discharge III of the electric duct 22σ return air fan 23 is divided into a flow path to the air conditioner 1 and a flow path to the exhaust port 3, and four electromagnetic dampers 24 and 25 are interposed in each branch path. There is. This electromagnetic damper 24.25 is also controlled h';
The opening degree is adjusted by 01c, empty 1;, 1 aki 1
The return air and exhaust volume are adjusted appropriately.

Exhaust fans 4tC, C are used to guide the exhaust sounds from various parts of the building to the exhaust port 5 at once through the exhaust route.

If there is a parking lot, part of the exhaust gas from the vc pump will be directed to the parking lot (this aspect will be described later - J-, 6), tV+

1νt+, .

Control panel C, f, external air contamination sensor 7, instruction signal Vr-el from detector 9, electromagnetic tamper 10. N, magnetic damper 24.25. This control, which controls the opening degree of 27, is computer-analyzed by the intermediate fire monitoring control board CC, and the internal pressure of the entire casing is controlled to a constant high pressure due to the external pressure. At the same time, as the degree of outside air pollution becomes severe, the amount of outside air fkk is reduced by several people, and at the same time, the exhaust volume is controlled to be slowed down in order to maintain pressurization.

In this way, the device shown in Figure 6 controls the pressurization of the entire building and also processes ash. This is done automatically, and it is possible to supply the necessary and sufficient oxygen while preventing drafts from entering the gaps in various parts of the building.In addition, when the pollution is severe, the amount of air to be pretreated by the VCRRS purifier 6 is reduced accordingly. Because of this, the capacity of this pretreatment device Vt(1) may be relatively small-scale, and the negative phase of the equipment can be reduced.

Items 5 to 8, 21, apply to buildings with difficult entrances and exits (for example, hotel entrances, factory loading/unloading gates, etc.) when applying the pressurized air conditioning equipment of the present invention. The air shower completely effectively prevents contamination from entering the dust section (subsystem E!2)'i.

Drafts can be virtually prevented by using the above-mentioned pressurized VC building inside the building, but if there is a doorway that is difficult to enter and exit, the exchange airflow due to the temperature difference inside and outside the building can cause the flow of human bodies entering and leaving the building. Contaminants enter the building along with the object.

This device is attached to the equipment shown in Figures 5 to 8, and is a building (for example, a hotel) that has a front entrance and a back entrance I + 3R as shown in Figure 5.
The first floor plan is shown. Note that D in FIG. 5 is a normal entrance door, and an entrance/exit device tu according to the present invention is attached alongside this normal entrance door D.

FIG. 6 is a plane cross section taken from the center of the doorway device tlU, FIG. 7 is a plane 1i;f plane of the ceiling portion of the doorway device H, and FIG. 8 is a view from the front of the doorway device. As shown in these figures, this entrance/exit device has a passage space 63 between the outer door 51 and the inner door 52. A plurality of air outlets 55 are provided on the wall surface and ceiling of the screen side and on the ceiling to blow out high-speed airflow into the passage space 66. An air circulation path is formed with an air blower 34 interposed therebetween, and a filter unit 56 is installed in this air circulation path.

The outer door 61 and the inner door 32 are cross-shaped doors that rotate on one vertical axis, and the entire center of the cross-shaped door is placed at the entrance and exit so that the passage of gas is reduced even if the rotational position is at any position. Eri is small.

A passage space 33 into which the deceased can enter is formed between the two revolving doors 51 and 62.

This passage space 63σ both revolving doors 61 and 52, both 1u

A large number of directional golden-white air outlets 65 are arranged inside 3,
On the other hand, a suction port 42 is provided below both side walls 37 and 68. Then, the blower 54.34' is installed so as to suck all the air in the perforation of the attic space VC7;

Therefore, one pre-filter is used for the return air taken into the double wall space from the passage space 66 through 42 suction ports.
After the coarse particles are removed in step 44 and harmful gases are removed, the double wall space i) is moved into the outside ceiling space, and the blower 3 is removed.
4.64' to 56.36' i
Roughly fine particles 75 are captured here and then supplied to each outlet 35+C through 43 supply air ducts, and from each outlet the purified raw air is made into an air jet and -C outlet σ. In fact, 1, this 1 agent lc, 1 person in the passageway Shiba, 7, only the object bald hair is attached to it with a shower tray, 7, and if ξ contamination ° 1 substance is blown away, this Contamination after one air shower is 9 air old and sucked into the suction port 42 and circulated. In addition, contaminants accompanying human bodies and objects that enter the building through the passageway space are removed.
Tight clothes and shoes! If you add actions such as brushing, the effect of preventing contamination will be further enhanced.

On the other hand, the driving VC structure of this device U, the negative pressure in the double wall space and the space outside the ceiling, and the high positive pressure in the passage space, but virtually the entire device is inside the building. By installing this, even if airflow flows outside the outside door 31 (1v from By installing a pressure regulating damper 45 between the space and the building interior space to absorb the pressure difference, high negative pressure can be suppressed by using non-contaminated air. In this way, the intrusion of contaminated outside air into the building through the entry and exit locations can also be effectively controlled. 7. An instruction signal from the 'port? The local control panel c2 receives it, and the opening f1f is adjusted based on the instructions from the central monitoring control panel CC (Fig. 2). To start and stop the drive of the unit @U. In response to the entry and exit of people, objects, etc., the system is turned on and off, and the central monitoring and control panel CC constantly monitors its status and performs appropriate control according to the air condition.

In this way, even if the building has an entrance/exit where people frequently enter and exit, the above-mentioned building 11j pressure control system will effectively prevent contaminants from entering the building through the entrance/exit. will be defended against.

Next, when implementing the present invention in a building that has a parking lot (the above-mentioned subsystem 531i'), we will discuss. Conventionally, in a general building, the entrance to the parking lot is left open, and the parking lot inside the parking lot is It was common knowledge that the exhaust gas of the vehicle was being discharged into the outside.Contaminants adhered to cars and were carried into the building; The pollutants σ are not discharged outside the system and are often accumulated in the VC building.7゜In the present invention, the accompanying pollution Y1゛4 due to the introduction of vehicles into the building exhaust from the I-E system? We propose a method in which the exhaust gas is used to prevent the entrained pollutants from leaking into the building.The method σ according to the present invention is as shown in Figs. In the parking lot in the building, there is a parking lot near the ceiling on this floor.
'i (A jet airflow blowing unit for air conveyance is arranged, and this unit VcJ: This unit conveys air 10,000 times in the direction of the arrival and departure of the air car on this floor, and sucks the air that has been conveyed to the table entrance. This air is unique in that it is blown outward from air blowing nozzles or slits installed around the table entrance passage, and a part of the exhaust air from the entire building is used as this air. F. The amount of exhaust gas is controlled to such a condition that pressurization control of the internal pressure of the building is carried out.

To explain the concrete VC according to the embodiment shown in Figure IHi VC, Figure 9 shows the method of conveying air according to the present invention in a parking place in a building. 521fr installed, air supply port by air supply fan 53! 7.

e us jet air #, in order to blow out all the air, the surrounding air near this jet stream is 11 in the direction of the jet stream.
It is transported by four pulls. The structure of this unit itself is to supply high-pressure air to the jet nozzle.When using the surrounding air to form a jet stream, the air taken in from the surrounding air is brought into high pressure by the fan, which is then used as the jet nozzle. It has a structure for supplying air to a nozzle, and when a separate system of air (exhaust air) is used to form a jet stream, a jet nozzle is placed in the exhaust duct of +':%l:Edo air. 55a to 55et: ↑It is placed near the ceiling of the parking place, and the surrounding air inserted by the jet stream of unit 55a is the next unit)

The jet stream is used as a conveyance means, and the jet stream is used as a conveying means. 1.6 Ambient air 7' 1.6 Ambient air 7' 1.6 Ambient air vent 7' 1.6 Ambient air vent 7'1.

Figures 10 to 12 show all the details of the entrance to Ichikawa Park.A car entering from outdoor direction A to indoor direction B receives air treatment in this population area, and at the same time the polluted air outside is released. Is this a structure that prevents people from entering the parking lot through the opening of this entrance? It shows.

In other words, the air blowing device installed at the mold entrance π is the air intake 1 for blowing all the air in the parking lot.
There are air blowing slits 59 to 61 provided around this military passageway and tilted in the direction π toward the outdoors, and fans 58 and 58 for pumping air taken in from the air intake port 57 to the slits 59 to 61vc. ' and are arranged as units.

In the illustrated example, the air 11y inlet 57μ is installed near the ceiling of indoor B to allow the air conveyed by the rearmost jet air outlet 55ercJ: After creating high pressure with the fans 58 and 58' of the machine, the slits 59a in both ITi walls
59b, slit 60 on the ceiling surface, and 61 VC on the floor surface. There is. Therefore, when a car passes through this air blowing device 4, a high-speed oblique airflow is blown toward the entire surface of the VC car body from the direction of the car passing through, and the pollutants adhering to the car body are blown away in the outdoor direction A.

T4. of the parking lot set up separately for the car exit area. , combination [1-J
As shown in Figures 13 and 14, the air blowing device is much smaller in size than the population section. In other words, the fan valley can be made smaller than in the 10th to 12th examples, and the number of slits can also be reduced, so that the contaminated outside air can be discharged at this outlet. It is sufficient to form an air flow (rear) to prevent air from entering the building through the rear wall.Therefore, the slits μ on the floor and ceiling are omitted, and only the slits 59 on both sides of the walls are used to form an outward airflow. be able to.

In this process, a jet stream blower 1111 for air conveyance is used.
~The combination of the unit and the air blow device is used to ventilate the parking lot while creating an airflow that is the opposite of the conventional ventilation system for parking lots in buildings: V: M+i I/
, and the intrusion of outside air from the east in air polluted areas is completely prevented, and pollutants adhering to cars are also removed at the entrance, effectively preventing contamination inside the building via the parking lot.

Next, let's talk about air treatment (subsystem 843) in cases where there is a relatively large-scale kitchen (for example, a hotel restaurant or a factory food service) in the building.This ff
If a 1f chamber exists, it will cause an imbalance when pressurizing the inside of the building, and if it is handled incorrectly, it may cause a fire through the exhaust hood.
For this reason, in the equipment of the present invention, the air processing system for such a kitchen VC is completely independent.
At the same time, this central monitoring and control panel 001/ (therefore, it is a VC that can control and also manage fire elements.As shown in Fig. 15), the kitchen exhaust hood 72, This kitchen exhaust hood 72

An exhaust fan 83 driven by a variable speed motor and an oil mist separator (480 is installed).

The oil mist separator 80 includes a ventilation panel 79 disposed substantially at a top angle with the direction in which the exhaust gas travels, a spray nozzle 85 disposed to spray water toward the surface of the ventilation panel 79, and an eliminator 86. It is housed in a single casing, and a waste liquid outlet 87 is provided at the bottom of the casing. By sprinkling water on the surface of the drain 51 and the filter 9, the oil mist is effectively separated from the kitchen exhaust gas which is agitated π times, and is discharged from the oil mist separator as oil emulsion wastewater. 80 units of this oil mist separation device,
It not only functions to remove oil mist in the kitchen exhaust, but also functions as a fire suppression shutter to prevent flames entering from the kitchen exhaust hood 72 from spreading.

The oil emulsion wastewater discharged from the oil mist separator @ 80 is purified of oil and fat by the 5+ unit 81 and then circulated again as water sprinkling. This oil and fat separation device 8

This light and/or heat sensor 82t''j and a special sensor that outputs a signal when the temperature of the kitchen exhaust hood 72 continues to be above a predetermined temperature for a predetermined time are all used. Also, this temperature sensor 1c is used. In addition to detecting FI!lt, a photoelectric switch that detects all flames is attached to the kitchen exhaust hood, and when the flame continues for a certain period of time, the Ic IIJ
It is configured as a fire detector that sends control signals. Therefore, it consists of two devices: the sensor VC, 82 shown in FIG. I am working on VC. In addition, a 1071″r earthquake detector is shown, which is set to Ic so that the rotational speed of the exhaust fan 83 can be controlled based on the signal from the flame sensor 106 installed near each range.

The extinguishing agent injection device 88 includes a extinguishing agent nozzle 100 for injecting extinguishing agent toward the range 711C from the vicinity of the kitchen exhaust hood 72, and various equipment for supplying the extinguishing agent to the extinguishing agent nozzle 10'OIC. This fire extinguishing equipment A1 consists of a water supply pump 101, a light water stock solution tank 102, a mixer 103, a header 104, an electric CO2 cylinder 105, etc. The 4% π from the sensor 82 determines π, which is carried out when the temperature of the gas passing through the kitchen exhaust hood 72 is above a predetermined value and continues for a predetermined time, and the flame generation continues for a predetermined time.

In this way, when a relatively large-scale kitchen exists in a building, the local control panel 84 (04) uses a separate system to handle the kitchen exhaust gas under the direction of the central monitoring control panel CC to keep the internal pressure of the building balanced. This subsystem 8411 has a management system that handles processing while coordinating and prevents fire hazards.
? Therefore, at the same time, it becomes VC.

In implementing the present invention, it is also important to take countermeasures against water contamination in a cooling tower, which is one part of the air conditioning system, ie, cooling water contamination caused by contact with contaminated outside air. The subsystem 35 for preventing contamination of the cooling tower-Hino water system will be specifically explained below with reference to the embodiment shown in Figure 16.

As described above, the present invention is applicable to air-polluted areas where there is a lot of ash fall, ≦) areas with severe outside air pollution such as overcrowded cities and industrial areas VC8? This method provides a new method for controlling the intrusion of outside air contamination by controlling the air treatment. If you combine any of the S5's 11 jars and 2 or more persimmons, it will be 1'l (even if there is, this is an effort to achieve the initial purpose. Even in areas where new development was delayed due to air pollution during the period t'--f, it will make a significant contribution to the construction of modern factories and international-class hotels.
