In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will optionally be described in detail below with reference to the accompanying drawings.

Referring to FIG. 1, the present application provides a laboratory comprising a plurality of laboratory units 10. As shown in FIGS. 1 and 2, according to a laboratory according to a specific embodiment of the present invention, each laboratory unit 10 includes a first area 1 and a second area 2. That is, the laboratory can be constructed by a plurality of laboratory units 10, and the laboratory units 10 can be subdivided into the first area 1 and the second area 2. In the specific implementation, the first area 1 and the second area 2 can be It is separated by a partition to achieve the purpose of isolating the gas environment of the two regions so as to avoid mutual influence.

Specifically, the first area 1 may include a first air supply valve 11, a first air exhaust valve 14, a first air supply connection duct 15 and a first air exhaust connection duct 16. Wherein, one end of the first air supply connection pipe 15 is connected with the main air supply pipe (not shown in the figure), and the other end forms a first air supply port 12 which is communicated with the gas environment of the first area 1; the first exhaust air connection pipe One end of 16 is communicated with the exhaust main pipe (not shown in the figure), and the other end forms a first exhaust port 13 that communicates with the gas environment of the first area 1; the first air supply valve 11 is arranged in the first air supply connection In the pipeline 15, the first exhaust valve 14 is arranged in the first exhaust connection pipeline 16. Specifically, both ends of the first air supply valve 11 are respectively communicated with the first air supply connecting pipe 15, and both ends of the first air exhaust valve 14 are respectively communicated with the first air exhaust connecting pipe 16. The second area 2 may include a second air supply valve 21, a second air exhaust valve 23, a second air supply connection duct 25 and a second air exhaust connection duct 26. One end of the second air supply connection duct 25 is connected to the air supply main duct, and the other end forms a second air supply port 22 that communicates with the gas environment of the second area 2; one end of the second exhaust air connection duct 26 is connected to the air exhaust main duct The other end forms a second air outlet 24 that communicates with the gas environment of the second area 2; the second air supply valve 21 is arranged in the second air supply connection pipe 25, and the second air outlet valve 23 is arranged in the second The exhaust air is connected to the duct 26. Specifically, the two ends of the second air supply valve 21 are respectively communicated with the second air supply connecting pipe 25; the two ends of the second air exhaust valve 23 are respectively communicated with the second air exhaust connecting pipe 26.

In a specific implementation, the main air intake duct can be communicated with an air-conditioning system, and the main exhaust air duct can be communicated with the outdoor atmospheric environment. And the gas environment (such as pressure, air volume, etc.) in each area (i.e., the first area 1 and the second area 2) and even each laboratory unit can be adjusted by adjusting the exhaust valve and air supply valve set in it, so as to Bring each area (or laboratory unit) to its desired gaseous environment. For example, if the first area 1 needs negative pressure and the second area 2 needs positive pressure, you can adjust the air supply volume of the first air supply valve 11 and the air supply volume of the first air exhaust valve 14 in the first area 1 respectively. Exhaust air volume, so that the pressure condition in the first area 1 reaches the set negative pressure value, so that the first area 1 is a negative pressure environment. By adjusting the air supply volume of the second air supply valve 21 and the exhaust air volume of the second air exhaust valve 23 in the second area 2, the pressure condition in the second area 2 can reach the set positive pressure value, so that the first The second area 2 is a positive pressure environment. Specifically, when the air supply volume in a certain area is greater than the exhaust air volume, the area is positive pressure; and when the air supply volume is less than the exhaust air volume, it is negative pressure.

Those skilled in the art should understand that different air valves have different adjustment methods. Some can adjust the expansion and contraction of the airbag according to the pressure, some can adjust the gap between the valve body and the valve wall according to the pressure, and some can also adjust the expansion and contraction of the spring according to the pressure, so the adjustment of the air valve can be carried out with reference to the specific operating instructions of the air valve.

In the present invention, by dividing the laboratory into a plurality of laboratory units 10, each laboratory unit 10 can be subdivided into a first area 1 and a second area 2, and each of the first area 1 and the second area 2 is independently The air supply valve and air exhaust valve are set, so the air exhaust valve and air supply valve in the area can be adjusted according to the gas pressure environment required by each area to control the air intake and exhaust air volume of each area, thereby This enables each laboratory unit 10 to meet gas environment requirements such as respective required pressure conditions. In addition, since each laboratory unit 10 is connected to the main air intake duct and the main exhaust air duct through pipes, it is not necessary to install an air conditioning system in each laboratory unit 10, and each laboratory unit only needs to be connected to the same The air-conditioning system of the main unit is connected, and the gas replacement in each laboratory unit can be realized, which saves the construction cost of the laboratory and reduces the energy waste.

Generally, a laboratory may include an experimental operating room and a buffer room, wherein the buffer room is set between the experimental operating room and the external environment, and its function is to isolate the outside world and the experimental operating room, so as to prevent the outside from interfering with the environment of the experimental operating room. In the present invention, the first area 1 may be an experimental operation room, and the second area 2 may be a buffer room. As shown in FIG. 2, the experimenter can first enter the buffer chamber through the door 200 of the buffer chamber, and then enter the experimental operation room through the door 100 of the experimental operation room to conduct experiments. Of course, in other embodiments, the first region 1 can also be set as a buffer chamber, and the second region 2 can be set as an experimental operation room. Taking the first area 1 as an experimental operation room and the second area 2 as an example of a buffer chamber, in the multiple laboratory units 10 of the laboratory, the first area of the multiple laboratory units can be allowed to communicate as an experimental operation. The chamber, and the second area of multiple laboratory units are connected as a buffer chamber, so as to achieve the purpose of changing the space of the experimental area.

It should be noted that although the first area and the second area shown in FIG. 1 are regular cuboid areas adjacent to each other, their widths and heights are equal. However, the size and shape of the first area (or the second area) of the laboratory unit provided by the present invention are not limited thereto. The length, width, height or shape of the first area and the second area can be set according to actual needs. The size and shape of the first region (or the second region) may vary from laboratory unit to laboratory unit, e.g., as shown in FIGS. 3-5. In the laboratory units shown in FIGS. 3 and 5, the first area 1 is a cuboid structure with a gap, and the second area 2 (shown in the shaded part in the figure) is also a regular cuboid. 2 is arranged in the notch of the first area 1. The difference is that the size of the notch in the second area 2 in FIG. 3 is smaller than that in the first area 1, while the size of the notch in the second area 2 in FIG. 5 is exactly equal to that in the first area 1; Although the second area 2 (shown by the shaded part in the figure) is the same as in FIG. 1, it is a regular cuboid adjacent to each other, but different from that shown in FIG. 1, the lengths of the first area 1 and the second area 2 in FIG. 4 are different. and width are not equal.

Optionally, in a specific embodiment of the present invention, the laboratory may further include multiple experimental areas, and each experimental area may be formed by splicing at least one laboratory unit 10.

That is, one or more laboratory units 10 can be used for splicing and assembling according to the individual needs of the user, so as to form the experimental area required by the user. The size of the experimental area is spliced according to the needs of the user, and the pressure conditions of the experimental area are adjusted according to the needs of the user.

Using the above method, when the user needs a larger area of the experiment area as a laboratory, it can be assembled into an experiment area that meets the user's needs by splicing multiple laboratory units; and when the user needs a smaller experiment area as a laboratory When using the space of the test area, it is also possible to separate the assembled large-area experimental area by the partition, but when using the partition to divide the space of the experimental area, it is necessary to ensure that each separated area has at least one exhaust valve and An air supply valve, so that the user can make the laboratory gas environment meet the experimental requirements by adjusting the air exhaust valve and the air supply valve. Thereby, the recycling of the laboratory is realized, and the problem of having to rebuild the laboratory due to the change of the area required by the user for the laboratory is effectively avoided, that is, the construction cost of the laboratory is effectively reduced.

Specifically, when splicing and assembling the experimental areas, the placement positions of the laboratory units may be different, that is, the first area 1 of one laboratory unit 10 may be adjacent to the second area 2 of the other laboratory unit 10. It can also be that the first area 1 of one laboratory unit 10 is adjacent to the first area 1 of the other laboratory unit 10, either the long side of the first area 1 and the long side of the second area 2 are adjacent the broad side of the first region 1 and may be adjacent to the long side of the second region 2. Not required here.

When the experimental area required by the customer is large, two, three or more laboratory units 10 can be assembled by splicing, and the specific number of laboratory units 10 used for splicing the experimental area can be based on the customer's requirements. The experimental area is determined. When splicing, each laboratory unit can be spliced according to certain rules according to the needs of customers. For example, each laboratory unit can be spliced, a partition is set between the first area and the second area of each laboratory unit, and a partition is also set between each area of different laboratory units, that is, each laboratory unit All exist as an independent laboratory operation room; of course, the first area or the second area of some laboratory units can also be combined to form a larger laboratory operation room. Exemplarily, the following three embodiments are used as examples to specifically describe the different types of splice ng multiple laboratory units into one experimental area. In the following three embodiments, the shapes shown in FIGS. 3 to 5 are used. Laboratory units are spliced, but the type of experimental area is not limited to this.

The first area A101 and the first area B201 are two different experimental operating rooms. During the experiment, the experimenter can enter the first area A101 through the second area A102 of the A unit, and enter the first area through the second area B202 of the B unit. B201. In addition, the first and second areas of each laboratory unit and each area of different laboratory units are isolated by partitions, so as to ensure that the pressure conditions in each area are independent of each other. That is, the air pressure in each area is set by adjusting the air supply valve and the air exhaust valve in each area, so that the experimenter can perform different experiments in the first area A101 and the first area B201 that meet the preset conditions respectively.

FIG. 7 is a schematic diagram of the assembly of the experimental area provided in another embodiment, the laboratory is assembled by three laboratory units, the three laboratory units are respectively recorded as A unit, B unit and C unit, the arrows in the figure It is the direction for the experimenter to enter the experiment area. Specifically, unit A includes a first area A101 and a second area A102, unit B includes a first area B201 and a second area B202, and unit C includes a first area C301 and a second area C302. During splicing, the broadside a22 of the second area A102 of the A unit is made to be adjacent to the broadside b22 of the second area B202 of the B unit, and the broadside a12 of the first area A101 of the A unit and the broadside of the first area B201 of the B unit The long side b11 is adjacent to each other, the broad side b12 of the first area B201 of the B unit is adjacent to the broad side c12 of the first area C301 of the C unit and the long side c21 of the C unit second area C302, and the second area C302 of the C unit is adjacent. The broad side c22 is adjacent to the long side c11 of the first region C301 of the C unit. The first area A101, the first area B201 and the first area C301 are used as three different experimental operation rooms. During the experiment, the experimenter can enter the first area A101 of the unit A through the second area A102 of the unit A, and pass the unit B. The second area B202 enters the first area B201 of the B unit, and enters the first area C301 of the C unit through the second area C302 of the C unit. And the first and second areas of each laboratory unit and each area of different laboratory units are isolated by partitions, and the air supply valve and air exhaust valve of each area are adjusted respectively to set the air flow in each area. pressure, so that the experimenter can perform different experimental operations respectively in the first area A101, the first area B201 or the third area C301 that meet the requirements.

Embodiment 3

FIG. 8 is a schematic diagram of the assembly of the experimental area provided in another embodiment, which is the same as the experimental area provided in the embodiment shown in FIG. 7, and the laboratory is also composed of three laboratory units (Unit A, Unit B and Unit C).) are spliced together, the arrow in the figure is the direction of the experimenter entering the experimental area. Specifically, unit A includes a first area A101 and a second area A102, unit B includes a first area B201 and a second area B202, and unit C includes a first area C301 and a second area C302. During splicing, the broad side of the second area A102 of the A unit is adjacent to the broad side of the second area B202 of the B unit, and the broad side of the first area A101 of the A unit is adjacent to the long side of the first area B201 of the B unit, the broad side of the first area B201 of the B unit is adjacent to the broad side of the first area C301 of the C unit and the long side of the second area C302 of the C unit, and the broad side of the second area C302 of the C unit is adjacent to the first area of the C unit. The long sides of an area C301 are adjacent to each other. However, unlike the experimental area shown in FIG. 7, in the embodiment shown in FIG. 8, not every area needs to be separated by a partition. Between the two areas C302, between the first area C301 of the C unit and the first area B201 of the B unit, and between the second area C302 of the C unit and the first area B201 of the B unit, there are partitions, so that the C The second area C302 of the unit forms an independent gas environment and serves as an experimental operating room. However, between the first area A101 of the A unit and the first area B201 of the B unit, and between the second area A102 of the A unit and the second area B202 of the B unit, no separator is provided. The first area A101 of the unit and the first area B201 of the B unit are connected into one area, and by adjusting the dampers in the first area A101 of the A unit and the first area B201 of the B unit respectively, the first area A101 and the first area B201 of the B unit are adjusted. The first area B201 has the same gas environment (e.g., equal pressure conditions), so that a larger experimental operation room can be formed, that is, the first area A101 and the first area B201 are jointly used as an experimental operation room. Similarly, the second area A102 of the A unit and the second area B202 of the B unit are also communicated into one area. By adjusting the dampers in the second area A102 and the second area B202, the second area A102 and the second area B202 has the same gas environment, which together form a buffer chamber. A partition is provided between the buffer chamber formed by the second area A102 and the second area B202 and the experimental operation room formed by the first area A101 and the first area B201 to isolate the buffer room from the experimental operation room. In this way, it is realized that the experimenter can perform different experiments in two different experimental operating rooms that meet the requirements.

Optionally, each laboratory unit 10 may further include an air supply branch duct 4 and an air exhaust branch duct 5. Specifically, the first air supply connection duct 15 and the second air supply connection duct 25 are both connected to the air supply branch duct 4, and are connected to the air supply main duct through the air supply branch duct 4; Both of the two exhaust air connection pipes 26 are connected to the exhaust branch pipe 5, and are connected to the exhaust main pipe through the exhaust branch pipe 5. That is, the air supply branch pipes 4 are respectively connected with the first air supply connection pipe 15, the second air supply connection pipe 25 and the main air supply pipe; the air exhaust branch pipes 5 are respectively connected with the first air exhaust connection pipe 16, the second air exhaust connection pipe The connecting duct 26 is connected to the exhaust main duct. Optionally, a recooling coil and/or a reheating coil 3 may be provided on the air supply branch pipe 4 to adjust the temperature of the gas in the air supply branch pipe.

In a specific implementation, the first air supply connection duct 15, the first exhaust air connection duct 16, the second air supply connection duct 25, the second exhaust air connection duct 26, the air supply branch duct 4 and the exhaust branch duct 5 can be provided In the interlayer at the upper part of the ceiling of the laboratory unit 10, it can avoid occupying the experimental space. Optionally, each laboratory unit 10 is provided with only one air supply branch duct 4 and one air exhaust branch duct 5, that is, the first area 1 and the second area 2 in the laboratory unit 10 share one air branch duct 4 and one air branch duct 4. Exhaust branch pipe 5.

Optionally, the ratio of the fresh air volume in the first area 1 to the volume of the first area 1 is greater than or equal to 12, and the ratio of the fresh air volume in the second area 2 to the volume of the second area 2 is greater than or equal to 12.

Specifically, the ratio of the new air intake volume Q in a certain area to the volume V of the area is the ventilation frequency AC in the area. When the shape of the area is approximately a rectangular parallelepiped, the volume V is further equal to the area S of the area and the volume of the area. The product of the height H of the area, and the area S of the area can be expressed as the product of the length L and the width W of the area. Therefore, when the area is approximately a cuboid, the number of changes satisfies:

Because the operator's breathing or doing experiments will make the gas in the laboratory turbid or even suspended with particulate matter that is harmful to the human body, there are certain requirements for the gas environment in the laboratory. Taking into account the setting requirements of laboratory temperature, humidity and gas pressure, in the present invention, the number of air changes in the first area and the second area is set to at least 12 times, so as to ensure that the temperature, humidity and pressure in each area conform to the experimental environment. requirements and without discomfort to the experimenter.

Therefore, the air supply valve and the air exhaust valve can be adjusted according to the length, width and height of the first area and/or the second area and the number of air changes required by the area to control the fresh air volume to reach the required range.
