1. How large a clean room is suitable for a high-efficiency air supply outlet of 500m³/h?

When the single air volume of a high-efficiency air supply outlet is 500m³/h, it cannot be directly said that it is suitable for a certain area of ​​clean room.

Because the amount of air supply required in a clean room is related to the following factors:

• Room area

• room height

• Design air exchange rate

• Cleanliness level

• Indoor equipment and process conditions

• Air flow organization method

• Number of air outlets

• Return air method

If you use the air exchange rate method to make a preliminary estimate, you can use:

Total air supply volume of clean room = room area × room height × number of air changes

If the design air volume of each high-efficiency air supply outlet is 500m³/h, then:

Number of air supply outlets = total air supply volume ÷ 500

Therefore, the clean room area corresponding to the 500m³/h high-efficiency air supply outlet needs to be calculated based on specific design conditions.

2. How to calculate the clean room area for a 500m³/h high-efficiency air supply outlet?

Assumptions:

• Air volume of a single high-efficiency air outlet: 500m³/h

• Room height: 3m

• Design air exchange rate: 30 times/h

Then, the theoretical room volume corresponding to a 500m³/h air supply outlet is:

500 ÷ 30 = 16.67m³

If the room height is 3m:

16.67÷3≈5.56m²

In other words, assuming that the room height is 3m and the design air change rate is 30 times/h, a single 500m³/h air outlet can be used as the basis for preliminary air volume estimation of a space of about 5.6m².

But this is not a fixed applicable area.

If the design air exchange rate changes, the corresponding area will also change.

3. Under different air exchange times, what area can 500m³/h correspond to?

Taking a room height of 3m and a single air supply outlet of 500m³/h as an example, you can follow:

Area = 500 ÷ (number of air changes × 3)

Carry out theoretical calculations.

This table is suitable for preliminary estimates。

In actual clean room projects, the final number of air outlets cannot be directly determined based on this table alone.

4. Why can’t the 500m³/h high-efficiency air supply outlet directly correspond to a fixed area?

The main reason is that different clean rooms have different design air supply conditions.

For example, two clean rooms with an area of ​​100m²:

A clean room:

• Area: 100m²

• Height: 3m

• Design air exchange rate: 20 times/h

Total air supply volume:

100 × 3 × 20 = 6000m³/h

If a high-efficiency air supply outlet of 500m³/h is used:

6000 ÷ 500 = 12

Clean room B:

• Area: 100m²

• Height: 3m

• Design air exchange rate: 40 times/h

Total air supply volume:

100 × 3 × 40 = 12000m³/h

If a high-efficiency air supply outlet of 500m³/h is still used:

12000 ÷ 500 = 24

It can be seen that although the area of ​​the two rooms is the same, the designed air supply volumes are different, so the number of air supply outlets required is also different.

5. What type of clean room is the 500m³/h high-efficiency air supply suitable for?

500m³/hHigh-efficiency air supply vents can be used as a design air volume specification for the end air supply vents of some clean rooms, but the specific scope of application needs to be determined according to the project design.

The more common judgment conditions include:

Therefore, you cannot only use '500m³/h' to determine which cleanliness level is suitable.

6. Can a 500m³/h high-efficiency air supply outlet be used in a 100-square-meter clean room?

Calculations can be made, but the design conditions need to be known first.

For example:

100m² clean room, floor height 3m.

If the design air change rate is 20 times/h:

100 × 3 × 20 = 6000m³/h

500m³/h one air outlet:

6000 ÷ 500 = 12

Therefore, about 12 preliminary air volume configurations can be made.

If the design air change rate is 30 times/h:

100 × 3 × 30 = 9000m³/h

but:

9000 ÷ 500 = 18

Therefore, for the same 100m² clean room, the required number of 500m³/h air outlets may be different.

Ultimately it needs to be confirmed based on project design conditions.

7. What size of clean room area is suitable for a 500m³/h high-efficiency air supply outlet?

If you only make theoretical estimates, you can use the following formula:

Corresponding area of ​​a single air outlet = 500 ÷ (design air exchange times × room height)

For example:

The room height is 3m and the design air exchange rate is 25 times/h:

500 ÷ (25 × 3)≈6.67m²

In other words, each 500m³/h air outlet can be initially estimated as approximately 6.7m².

If a clean room area is 67m²:

67 ÷ 6.67 ≈ 10 air outlets

This is just a theoretical calculation based on the number of air changes.

If the clean room uses other air flow organization methods, or there are local high-clean areas, equipment heat dissipation, process exhaust, etc., it needs to be recalculated based on the actual design.

8. When selecting a high-efficiency air supply outlet of 500m³/h, don’t just look at the air volume.

After determining 500m³/h, it is also necessary to confirm the specifications of the high-efficiency filter and the structure of the air outlet.

It is recommended to confirm at least the following:

Design air volume → Filter specifications → Filter resistance → Box size → Air inlet mode → Dispersion mode → Installation dimensions → System static pressure

For example, for the same high-efficiency air supply outlet of 500m³/h, if HEPA filters of different specifications are used, the filter surface wind speed, resistance and box structure may be different.

Therefore, when purchasing, you cannot only provide the parameter '500m³/h', but also need to determine the filter and installation conditions.

9. How to determine the number of 500m³/h high-efficiency air supply outlets?

It is recommended to adopt the following calculation process:

Clean room area → Room height → Designed number of air changes → Calculate the total air supply volume → 500m³/h single air outlet air volume → Calculate the number of air outlets → Adjust the air outlet layout

For example:

Clean room area: 150m²
Height: 3m
Design air changes: 30 times/h

Total air supply volume:

150 × 3 × 30 = 13500m³/h

500m³/h one air outlet:

13500 ÷ 500 = 27

Then 27 can be used as the preliminary number, and then adjusted based on the ceiling layout, equipment location, return air position and air flow organization.

10. What should you pay attention to when selecting a 500m³/h high-efficiency air supply outlet?

1. Don’t choose based on room size alone

Area is only one of the calculation conditions, and floor height and design air supply volume also need to be considered.

2. Do not regard the number of air changes as a fixed parameter for all clean rooms

The design conditions of different clean rooms, process areas and airflow organizations may be different and should be based on the project design.

3. Pay attention to filter resistance

The high-efficiency filter will produce a certain resistance and needs to be matched with the static pressure of the system fan.

4. Pay attention to the layout of the air outlets

After the number of air outlets is determined, you also need to check the specific layout on the ceiling to avoid just counting the number and ignoring the air flow organization.

5. Pay attention to maintenance methods

If the filter needs to be replaced regularly, space for maintenance and replacement should be considered in advance.

11. How to select the 500m³/h high-efficiency air supply outlet of Aili Industrial?

12. Frequently asked questions about 500m³/h high-efficiency air supply vents

1. How many square meters can a 500m³/h high-efficiency air supply outlet cover?

There is no fixed coverage area. It needs to be calculated based on the height of the room and the number of designed air exchanges. For example, when the height is 3m and the air exchange rate is 30 times/h, the theoretical corresponding area is about 5.6m².

2. How many 500m³/h air supply vents are needed for a 100 square meter clean room?

It is necessary to determine the design air exchange frequency first. For example, when the height is 3m and the air exchange rate is 20 times/h, the total air volume is about 6000m³/h, corresponding to about 12 500m³/h air outlets.

3. Is 500m³/h suitable for ISO 5 clean room?

It cannot be judged based on 500m³/h alone. It needs to be determined based on ISO grade, airflow organization, room size, process requirements and overall air supply design.

4. Can the 500m³/h high-efficiency air supply outlet be used in ordinary clean rooms?

It can be selected as the terminal air supply equipment for some projects, but the specific requirements need to be determined based on the clean room design air volume and filter requirements.

5. How to choose between 500m³/h and 1000m³/h high-efficiency air supply vents?

The selection is mainly based on the total designed air supply volume, the allowable air volume of a single air outlet, ceiling layout, filter specifications and air flow organization, rather than simply comparing the air volume.

in conclusion

There is no fixed corresponding clean room area for a 500m³/h high-efficiency air supply outlet.

When calculating you can use:

Theoretical corresponding area of ​​a single air outlet = 500 ÷ (design air exchange times × room height)

For example, under the conditions of a room height of 3m and a design air change rate of 30 times/h:

500 ÷ (30 × 3)≈5.6m²

However, this result is a preliminary estimate at the air volume level. The actual project still needs to be confirmed based on the cleanliness level, air flow organization, filter specifications, air duct resistance, air outlet layout and equipment process conditions.

Therefore, when selecting a 500m³/h high-efficiency air supply outlet, it is recommended to first determine the total design air supply volume of the clean room , and then determine the air volume and quantity of a single air outlet.
