【 Weak current College 】 clean air conditioning design steps

Based on the underlying data to determine hot humidity load
According to the load calculation of wind, according to the calculation of air purification, whichever maximum
According to staff, pressure, technological requirements determine the new amount of wind
According to purify the level determines the level of filtering at all levels
Under load, heat and cold sources forms determine pipeline
Began to paint.
Of course this is only the most basic steps, specific design to trouble and more

1, first under clean level and volume calculation system air flow
2, determine when you finish, calculation of indoor air flow is always the sensible heat and humidity; calculation of heat and moisture than parameters;
3. in accordance with air flow and sensible heat calculation of air temperature difference based on the air!, to determine delivery status points
4. air status point "wet heating" process and the relative humidity of 95% line intersection point is: air handling of dew point temperature
5. from mixed point to the dew point temperature enthalpy difference between, on the basis of wind------calculates the chilling system requirements, the cooling capacity is the amount of cold air handling unit.
6. from the dew point temperature-to-air status points enthalpy difference, according to the calculated amount of wind is the system of heat.
7, the next step will also need to account for the amount of winter heating and summer heat which parameters the system then? Max ' as our conditioning tank heating quantity parameter.
8. According to the fresh air humidifying capacity calculated in winter

Clean air conditioning design and calculation of general steps!
Clean air conditioning design calculation general steps:
1. According to technological requirements determine the cleanliness level clean room and decided to use the whole room air purifier or local air purification, according to the table the table to determine the air flow patterns;
2. the calculation of the new amount of wind, take the following two major, calculation methods;
(1) compensation remains laboratory exhaust volume and pressure values for the required amount of fresh air.
(2) guarantee clean room per person per hour fresh air volume of not less than 40m3/hour
3. the calculation of the clean room cooling load and thermal load;
4. calculation of the air, take the following three items in maximum value, the calculation methods;
(1) in order to guarantee the cleanliness level of the air.
(2) depending on the heat load calculation determines. wet air of
(3) to clean indoor air supply of fresh (new air flow).
5. in accordance with the air supply, and cooling load and thermal load and choice of forms of calculation of air distribution, air distribution in all parameters;
6. determination of air heating and cooling of treatment programmes, with a secondary return air or air;
7. in accordance with industry requirements or airflow calculation to determine the supply air temperature difference and indoor and outdoor calculation parameters, in the figure determined i-d State point, calculation of air conditioner air handling, clean-room M3;
8. calculate the total cooling load and thermal load, select air treatment equipment;
9. check of clean indoor particulate concentration and bacterial concentration.
