What are the advantages of installing air conditioning unit in clean Engineering?
1 large air volume
Ed purification tells you that the cleaning project is mainly to filter the dust, bacteria, etc. in the air through the circulation of air volume, so as to realize the control of abiotic particles and biological particles in the air and reach the clean standard. Therefore, enough air volume is needed to ensure the cleanliness of the room. The air volume of clean engineering is generally calculated according to the indoor air change times, usually 10 times, or even dozens of times. Especially for one-way flow clean Engineering, the air change times are hundreds of times of the room volume.
Large air volume is a test for the strength of air handling unit, so clean air handling unit must first meet the requirements of high strength.

Pressure head of 2 fan is high
Generally, centralized air supply and return are also used in clean engineering to ensure the positive and negative pressure regulation requirements of clean engineering. Therefore, the pipeline resistance of clean engineering is more than twice that of ordinary air conditioning. In order to overcome these resistance, the air supply fan of the air handling unit is required to have enough pressure head. Therefore, the air supply fan of the air handling unit of the clean project generally adopts the fan with the wing shape of the rear bending machine, or the fan without the nest shell, so as to achieve the high pressure of the air supply and return head. The lower the air leakage rate of clean room air handling unit is, the more energy is saved for customers and the lower the operation cost is.
3 high temperature and humidity control accuracy
Different from the requirements of general comfort air conditioning to meet the comfort of personnel, the accuracy of temperature and humidity control is to meet the process requirements. For example, in the manufacturing of some electronic products, the control requirements of temperature and humidity are very strict. In medical and experimental animals, the control accuracy of temperature and humidity is also clearly required. In order to achieve constant temperature and humidity, it is required that the air handling unit at least has refrigeration, heating, humidification, dehumidification and other functional sections, and requires precise control.
4 strict control of positive and negative pressure
In order to prevent dust and bacteria from spreading to the clean area or cross infection caused by the spread of virus and bacteria, the positive and negative pressure control of clean room is very important, especially in medical occasions, it is necessary to prevent the spread of radioactive dust, harmful gas, odor and bacteria, so as to control them accurately and effectively It is very important to control the positive and negative pressure.
In practical engineering application, positive pressure maintenance is used in clean Engineering and general biological clean Engineering, but negative pressure control is used in toxic, harmful gas, flammable and explosive solvent and biological clean Engineering with special requirements. In order to have accurate control value of pressure difference, it is necessary to have a lower air leakage rate in the air handling unit of clean Engineering in order to have a higher control accuracy. At the same time, the shunt section with centralized air supply and return will be widely used in air conditioning box.
5. Good filtration system

Whether it is a clean project to meet the requirements of process design or a biological project to meet the requirements of medical, pharmaceutical, experimental animals, etc., the common feature is to meet the requirements of dust-free, which will be completed by a good air filtration system. The control degree of cleaning technology to microorganism and dust mainly depends on the performance of filter. The air filter needs to have good quality, once leakage occurs, it is impossible to reach the clean possibility. In addition to its own no leakage, the filter in the air-conditioning box should also pay attention to the sealing.

6. Frequency conversion technology
High energy consumption is brought by the characteristics of large air volume in clean room of pharmaceutical factory. Various energy-saving technologies are widely used in clean air-conditioning system. Frequency conversion technology is widely used in clean air conditioning system. In addition, Huandu fresh air fan selects the forced draft fan of the air handling unit in the clean project. The motor power is selected according to the final resistance of the filter. In the initial operation of the air conditioning system, the pressure of the fan is absolutely enough to overcome the resistance of the system to meet the use requirements. At this time, the frequency converter can reduce the speed of the fan, reduce the power consumption, and play a good energy-saving purpose.
With the operation of the system, the resistance of the filter is increasing, and the air volume of the air conditioner in the clean room of the pharmaceutical factory will be reduced. The air volume or static pressure in the air duct will provide the variable data to the frequency converter, and the frequency converter will increase the speed of the fan, which can meet the requirements of the air volume of the system. At the same time, it can adjust the speed of the fan, and maintain a good positive and negative pressure of the room Regulation. In addition, the frequency conversion fan can also be used to reduce the rotation speed of the unit and the air volume of the air supply fan when the clean project is not used, which is equivalent to the use of the duty fan.
7 considerable stability and reliability
With the rapid development of modern industry, industrial products have the characteristics of small volume and high value. If the clean air conditioner fails, it will bring thousands of losses, especially in medical clean engineering. If the air conditioner fails in the process of operation or delivery room, it will bring the safety of life. Therefore, the air conditioner is required to have considerable stability and reliability It is required that every part of the air handling unit should be purchased with products from manufacturers with good quality management. For example, certified high-quality fans and high-quality Motors should be used inside the unit. The new fans in Huandu should be used with great care. Especially the high-efficiency filter, if there is a small hole, it will bring countless bacteria. After The result is unimaginable. In addition, the production and testing of air handling units should also be strictly in accordance with national standards.
