Nowdays,our customers are curious about how to calculate what model or power their clean room will need,this is very important for them to budget their project.
So this time we mainly to introduce how to calculate the suitable power or consumption will the clean room need so will bring big help for our customers or someone is going to build their clean room.
Class 100 is equivalent to ISO5. The number of machine changes is 360. The algorithm is that the room volume X360 is equal to the air supply volume.
Ten thousand level is equivalent to iso7 level. The number of machine changes is 25-30. The algorithm is that the room volume X25 is equal to the air supply volume.
Class 100000 million is equivalent to class iso8-iso9. The number of machine changes is 15. The algorithm is that the room volume x15 is equal to the air supply volume
The following is the calculation of cooling capacity
The refrigerating capacity has a great relationship with the area. It is 110-180 watts per square meter. It can be calculated by dynamic or static. What are dynamic and static,
For example, this room is relatively closed, and few people enter it. It is static, so the watts per square meter will be less.
Dynamic means that there are often people in and out of the room. Each time the door is opened and closed, the indoor temperature will be affected. In this way, it is necessary to match a larger wattage. The static space is about 130 watts per square meter. For example, if the room is 10 square meters, 10x130 is equal to the cooling capacity.
The dynamic space is about 170 watts per square meter. For example, if the room is 10 square meters, 10x170 is equal to the cooling capacity.
An input power equal to about 750 watts.
Then why is it necessary to install an air valve in some places in the air duct routing diagram? What is the role of the air valve? For example, the room needs 5000 air volume, which is equal to five 1000 air volume high-efficiency air supply outlets. If the air valve is not installed on the air duct, it may send 6000 or more air volume to the room. At this time, the air valve plays the role of adjusting the air volume, adjusting the air volume to the air volume just used in the room, For example, 5000 air volume.
What is relative humidity
Relative humidity is the current degree of water vapor saturation in the air,
For example, the current relative humidity is 80%, so the current moisture content in the air is very high, people will feel moist, and it is not easy to dry clothes
For example, the current relative humidity is 20%, so the current moisture content in the air is very low, people will feel very dry, and it is easier to dry clothes.
The air temperature is 28 ° and the saturated water vapor pressure is 3.771kpa. The water vapor pressure in the air is 3.016kpa. According to the calculation formula, the relative humidity in the air in Xi'an is 80%, and 20% humidity can be absorbed in the air.
