FI118189B - Arranging ventilation particularly in a restaurant space divided into separate areas designated for smokers and nonsmokers using a downwardly directed air flow stop - Google Patents

Abstract

Air flow stops (16,16a) are made of transparent acrylic plate etc. and air input devices (13,13a) cover 50% of the free working space of employees working inside a counter (17), while the exiting air flow from workstations (12,12a) is in the direction of arrows (D) so that smoke from people at the counter or at a gambling table passes out of the room space via stops (6,6a) in border areas (4,4a). The stops (16) can be placed between smoking and nonsmoking areas (2,3), while a unit (22) regulates incoming air. An independent claim is included for a method of arranging ventilation in a room space.

Method of Arranging Workplace Ventilation and Workplace Ventilation Arrangement This patent application is separated from the previous patent application by a separate application.

The invention relates to a method for providing ventilation at a work station according to the preamble of claim 1.

The invention also relates to a workplace ventilation arrangement according to the preamble of claim 10.

10 A prior art method for providing ventilation in a room, such as a restaurant, in which low-speed air is supplied to the room from the floor near the walls or in the middle of the room and is generally vented from the roof structures. The purpose of this method is to provide replacement ventilation, whereby the supply air and the extract air are mixed as little as possible.

However, the provision of ventilation in a room space, in particular a restaurant space divided into areas for smokers and non-smokers, is problematic by the method generally used above. This is because tobacco smoke spreads from one or more areas intended for smokers .1. 20 quite easily for non-smokers and especially the borderline is wide * '· · wide and varies depending on the number of people in the restaurant and their movement. The obvious chemo to solve the problem is that the areas mentioned are · ·: completely constructed into different spaces. However, this is usually not the case, as the • • 1 restaurant space is to be maintained as a homogeneous area where both customers and 25 people can move relatively freely.

♦ · · • · * 1

Another major problem with the ventilation of the room, especially the restaurant, is: separate workstations in the area specifically for smokers. • · · Smoke usually smokes at the workplace and is particularly detrimental to workers who do not *: 2 smoke themselves. There is no obvious way in the art to solve this problem: / ·· 30. More recently, this issue has been the subject of discussion: 3:

This invention is intended to eliminate workplace ventilation problems. It is also an object of the invention to provide a new method of rigidifying ventilation to a workstation and providing a workstation ventilation rigidity.

The method according to the invention for providing ventilation to a work station is characterized by what is set forth in claim 1.

The workplace ventilation system according to the invention is characterized by what is set forth in claim 10.

Preferred embodiments of the invention are disclosed in the dependent claims.

In the method according to the invention, the supply air supply to the workstation is arranged

settle at a low flow rate, most preferably between 0.1 and 0.2 m / s, from above; and an area substantially corresponding to the work area of the worker and the supply air supply area is delimited by an air flow barrier downwardly directed downward from the roof structures, preferably by a wall; and air extraction is tracked from outside the work station in the country of occurrence. | /, -g

In the arrangement according to the invention, a low-velocity air intake device is fitted to the workstation and is fitted to roof structures such that the supply air is supplied to the workstation from above with a downward airflow obstruction arranged around the intake air device, preferably a wall configured to enclose an area air extraction * is arranged to occur outside the workstation.

··: ··· • · · «. ·. The starting point of the invention is that at the boundary between the area reserved for non-smokers in a restaurant and the area reserved for non-smokers, a barrier of air flows is provided on the roof surface and dehumidification in connection therewith. Warm air rises upward and tends to move near the roof structures and blend. Now the flow- • · «...

* ··· 'restricts the passage of air between areas and, in particular, the passage of smoke-containing air to the area of non-smokers in the vicinity of the roof of the area reserved for smokers. The air is removed in or near the airflow barrier.

t · • * * *. "· 30 The basic idea of the invention to provide ventilation to a workstation is to utilize an airflow barrier; it encapsulates the workstation in roof structures and introduces the air at a low velocity into the supply air from above to the workstation. The air is removed from the outside of the workstation, preferably in or in the immediate vicinity of the airflow barrier.

An advantage of the invention is that ventilation can now be monitored in a workstation arranged in a room, in particular in a restaurant, in such a way that tobacco smoke or the like 5 cannot penetrate into designated areas for non-smokers. The amounts of airborne contaminants that enter non-smoking areas are very low and below the established standards. The amount of noxious particles and other air pollutants in the room air, which are therefore mainly due to smoking, especially at workstations, is reduced by about 10 to about a fraction of the room air of current workstations.

A particular advantage of the invention is that it is possible to provide work areas in the areas intended for smokers where the amount of tobacco smoke and other similar harmful particles remains below the set target level. By doing so, for example, the restaurant bar can be divided into a smoking area and a 15 non-smoking area for employees, in accordance with the bar counter. Similarly, for example, game tables can be isolated in the area of smokers from smoke-free workstations.

In the following, the invention will be described in detail with reference to the accompanying drawing, in which the figure 20 illustrates a top view of a room, in particular a restaurant, above. . when the room is subject to a particular ventilation method and arrangement; Fig. 2A shows a cross-section of the barrier and at the same time a cross-sectional view AA of the room space in Fig. Y; · · · ** 1; • · 7 * · *,; - * * · · · · · · · · · · 2B is a bottom view of an obstacle of FIG. 2A;

Room 1, in particular restaurants, is divided into areas 2 in Figure 1; 2a, 2b; 3 such that the first region 2; 2a, 2b is a smoking area, i.e. a smoking area, and another area 3 is a non-smoking area, i.e. a non-smoking area. Each area of the nutrient-10 tolat or the like 1; 2a, 2b; 3 tables are usually placed with chairs for clients. The service staff and clients will then have the opportunity to move relatively freely within the smoking area and the non-smoking area.

Ventilation is provided in the room 1 so that the areas 2 for smokers and non-smokers; 2a, 2b; 3 to boundary 4; 4a, 4b, 4c, the downstream and uniformly longitudinal air flow barrier 6, preferably a wall, extends through the entire room space from wall to wall. Further, in the vicinity of the barrier 6 or in the immediate vicinity thereof, the air is removed from the room space 1;

The function of the barrier 6 is to restrict and prevent the smoking area 2; 2a, 2b, the upward flow of warm and contaminated air in the vicinity of the roof structures 20 to the non-smoking area 3. The barrier 6 thus severely limits the flow of horizontal airflow near the roof 5. The defrosting of the room: Y: space is arranged to occur at least in part by means of * · *: exhaust air means tracked in connection with barrier 6.

• * * • · **. ·· * Roof structures in Room 1, especially the dining area, usually include a lowered ceiling • »·" 25a 5a. Ventilation ducts, * .. ·· lamps and electric cables are placed between the actual ceiling and the suspended ceiling. The barrier 6 is then specifically arranged as a downwardly facing wall or the like from the lower ceiling 5a. The lower ceiling 5a is also considered to be a relatively airtight structure.

The height h of the barrier 6 from the roof structure 5 downwards is arranged substantially smaller than the height of the room. The height of the room is usually in the order of 250 - 270 cm. The height h of the barrier 6 is preferably between 15 and 70 cm. However, it should be noted that the barrier 6 «is arranged in the roof structure 5 such that the end 7c protruding with respect to its roof structure does not extend so far as to interfere with the movement of the restaurant space 1 or the like. As a result, it does not generally reach a height of 200 cm below the floor.

The sides 7a, 7b of the barrier 6 are vertical in the exemplary embodiments of the drawings, but they may also be inclined 5 or obliquely to the plane of a roof such as a ceiling 5a.

The barrier 6 can be made of many materials such as transparent acrylic sheet, wood, metal, fabric, etc.

A number of exhaust air openings 8 are followed on barrier 6. These exhaust air openings are arranged substantially in the longitudinal direction of barrier 6, i.e. in the direction of a room roof such as ceiling 5a, 10 and preferably over the entire length of barrier 6. The exhaust air openings 8 are connected by a suitable exhaust air duct 9 to the exhaust air device 10. The obstruction 6 itself may be e.g. hollow, whereby its interior space forms part of the exhaust air duct. The exhaust air openings 8, the exhaust air duct (s) 9, and the exhaust air device 10 together form at least a portion of the ventilation means of the room 1. Through the exhaust air openings 8, at least -15 parts of the exhaust air are first conveyed to the exhaust air duct 9 and further through the actual exhaust air device 10 out of the room 1.

The exhaust air openings 8 can be traced to the barrier 6 in a number of ways, as illustrated in FIG. 2A, 2B, 2C, 3A, 3B and 3C.

Exhaust air openings 8; 8a, 8b are most preferably provided with barrier 6; 6a, 6b, as shown in Figs. 2A, 2B and 2C. In this case, the barrier 6; 6a, 6b both sides 7a, 7b are intact.

Exhaust air openings 8; 8c, 8d it is possible to provide a barrier 6; 6c, 6d on both sides 7; 7a, 7b, but the exhaust air openings (not shown in the drawings) on the area 3 for the non-smoking V ·: 30 mats are not necessary. They can, of course, be used to enhance the ventilation in the non-smoking area 3. However, what is important in this case is that the n. i • * '**' '• · • · · «« * »· \ 6 118189 by expenditure in smoking area 2; 2a, 2b the deaeration takes place by the barrier 6; 6c, 6d effectively.

In the exemplary embodiments described above, the exhaust air openings 8 are arranged adjacent to the barrier 6. In the embodiment of Figure 4, a plurality of exhaust air openings 8; .. * 5 8e (and 8f) are provided by barrier 6; 6e in the immediate vicinity (cf. dashed line in Figure 1). Exhaust air openings 8; 8e (and 8f) is preferably provided by barrier 6; 6e adjacent to the roof structure 5, and in particular to the exhaust air duct 9 fitted thereto; 9b (and 9c). Exhaust air duct 9; 9b (and 9c) and at the same time the exhaust air openings 8; 8e (and 8f) are substantially * in the longitudinal direction of the barrier, either completely within the barrier 6; 6c to the roof junction 10, or e.g. 10-15 cm from it. Maximum exhaust air duct 9; 9b, 9c with exhaust air openings 8; 8c, 8d is, for example, 50 cm from the es-, 'ii tea.

Exhaust air duct 9; 9b with exhaust air openings 8; 8c is most preferably followed only by boundary 4; 4a on one side and particularly the smoking area 2; 2a. However, it may also be provided in the non-smoking area 3 of the barrier 6; 6e as shown in dashed lines in Figure 4. Also in this case-? air vents 8; 8c, 8d are connected to the exhaust air duct 9; 9b, 9c to the actual exhaust air device 10; 10a, by means of which at least part of the room air to be removed is moved out of the room 1.

In the above embodiments of the barrier 6, the exhaust air openings 8 are spaced apart from the openings, as can be seen in Figures 2B and 3B. In a preferred embodiment of the invention, the exhaust air openings 8; 8b, 8d being elongated substantially obstructed 6; 6b, 6d is a uniform length of · · · · ·. 2C and 3C.

It is most advantageous to arrange the supply of fresh supply air to one or more non-smoking areas 3; 3a. The supply air supply is effected by a supply air supply device 11, which is most preferably fitted to the roof structures 5 of the area 3 for non-smokers. The supply air supply is further arranged to occur at a low flow rate, preferably 0.1-0.2 m / s. In this case, the supply air supply unit is a low speed. ·· ♦, 30 air supply unit.

Again, the supply air units are specifically in the non-smoking area 3. ΐ 5 It has already been stated above that the deaeration of the room is followed by at least a barrier 6; 6a, 6b, 6c, 6d of exhaust air openings 8; 8a, 8b, 8c, 8d. However, the ventilation of the room 1, especially the restaurant, often needs to be intensified, and in that case the ventilation of the room is arranged to take place in the area specifically intended for smokers 2; 2a in connection with said obstruction 6, in addition to the monitored exhaust air flow - 10. In this case, it is preferable to provide one or more exhaust air devices 10; 10b smoking area 2; 2a to the roof structures 5 as illustrated in Figure 1. Exhaust air device 10; The placement of 10b in the roof structures 5 is most advantageous, since the so-called bottom-up warm and saturated with tobacco smoke can be effectively sucked in and removed from room 1.

15 Separate service points 12 are often provided in room 1, particularly in its restaurants; 12a, 12b such as a bar counter 12a for serving drinks and a game table 12b such as | card game table, figure 1. These points 12; 12a, 12b are mostly located in the smoking areas 2; 2a, or at least surrounded by partially or totally smoking area 2; r 2b. The problem with such workstations is to wrap workers in a state of fresh air and protect them from tobacco smoke.

The above workstation problem is solved according to the invention such that k. · *; to each work station 12; 12a, 12b, Figs. 5 and 6, particularly disposed in the region 2 for the cigarette pistons; 2a, 2b or such an area, ··. ·, The supply air supply is arranged such that: the supply air supply is carried out at a low flow rate * * \ .1 # 25, preferably between 0.1 and 0.2 m / s, with a suitable supply air device 13 ; 13a, 13b; the supply air supply is tracked from above, i.e. down from the roof structure 5, whereby the supply air device 13; 13a, 13b are thus arranged in connection with the roof structure 5; and supplying the supply air • * * ··· * to the event in its area 15; 15a, 15b from within where you work; and the supply air supply area 15 thus defined; 15a, 15b are delimited by an airflow barrier 16, preferably wall, arranged around this area and directed downwards from the roof structures 5. Further, it is preferred that the supply air temperature be maintained close to> ♦ room air temperature, preferably with a temperature difference not exceeding 5 ° C.

The ventilation arrangements according to the above method are illustrated in Figures 1, 5 and 6. Low speed supply air device 13; 13a, 13b are fitted to the workstation • «. *. : 35 12; 12a, 12b for roof structures. Fig. 5 shows the ventilation arrangement of a restaurant or similar bar counter 118189, while Fig. 6 shows a ventilation arrangement of a gaming table or kitchen counter, for example. Supply air device 13; 13a, 13b a downwardly directed airflow barrier 16 is imaged in the roof structures; 16a, 16b, preferably a wall. This airflow barrier 16 may be part of the actual room wall 235 or the like, as illustrated in Figure 5.

Air flow barrier 16; 16a, 16b determine the supply air supply area 15; 15a, 15b. Air flow barrier 16; 16a, 16b; 15a, 15b is substantially equal to the work area of the worker, i.e.. the area where the employee primarily serves customers. Air flow barrier 16; 16a, 16b; 15a, 15b 10 is, for example, at least half, preferably about 70-80%, even up to 100%, of the worker range. The supply air device 13 itself; 13a, 13b, in particular the feed portion fitted to its roof structure 5, is generally substantially smaller in area than the area delimited by the airflow barrier 16. Supply air device 13; The area 13a, 13b is e.g. 30 to 60% of the area delimited by the air flow barrier, but may be up to 100% in some applications.

However, in some cases, part of the airflow barrier 16 is part of the actual wall 23 of the room, so that it extends from top to bottom. With air flow barrier 16; 16a, 16b are thus enclosed supply air device 13; 13a, 13b and thus form a clear supply air area with low supply air velocities 20, i.e. in the order of 0.1-0.2 m / s. This prevents the impure air from mixing with the workplace air, i.e., the smoky air entering the smoking area 2; 2a, 2b to work station 12; 12a, 12b.
