The key parts of the workshop purification project mainly include the following seven items, which must be attached great importance to the design, construction, supervision and use of the purification project.

I. Telephone and fire alarm equipment:

Clean workshop set up telephone, talkback telephone, can reduce personnel in the clean area, reduce the amount of dust, can also be in case of fire in time with the external contact, but also create conditions for normal work contact. In addition, the fire alarm system should also be set up to prevent the fire is not easy to be found outside and cause significant economic losses.

Two, the air duct requires equal attention to economy and efficiency:

In a centralized or purified air conditioning system, the requirement for air ducts is both economical and effective air supply. The former requirements are reflected in low price, convenient construction, running cost, smooth inner surface resistance. The latter refers to good tightness, no air leakage, no dust, no dust, no pollution, fire resistance, corrosion resistance, moisture resistance.

Three, air conditioning purification needs to pay attention to energy saving:

Air conditioning purification is a large energy consumption, the design and construction should pay attention to energy saving measures. In the design, the division of the system and the region, the calculation of air supply volume, the determination of temperature and relative humidity, the determination of clean level and ventilation times, the fresh air ratio, air duct insulation, the influence of the bite form in the production of air duct on the air leakage rate, the influence of the connection Angle of the branch pipe on the air resistance, Flange connection whether air leakage, air conditioning box, fan, water chiller and other equipment selection are all related to energy consumption, so these details must be considered.

Four, according to the climate conditions to choose air conditioning box:

On the choice of air conditioning box, should consider the climate environment. If the winter temperature is low and the air dust content is large in the northern region, it should be added in the general air conditioning unit of the new air preheating section, the use of water type air treatment, so that it not only to the air dust and make it produce heat and temperature exchange to reach the required temperature and humidity. And in the humid climate, the air dust concentration is low in the southern region, there is no need to preheat the fresh air in winter, the air filtration and temperature, humidity regulation is used for the initial effect of filtration, cold surface adjustment of temperature and humidity, can also strengthen the temperature and humidity reduction process, and then through the medium effect filtration and terminal high efficiency or sub-high efficiency filtration. Air conditioning box supporting fan ** frequency conversion fan, which can not only save energy, but also flexibly adjust the air volume and pressure.

Five, the air conditioning room should be on the side of the clean room:

The location of the air conditioning room should be on the side of the clean room, which can not only save energy, but also be conducive to the arrangement of the air duct, and make the air distribution more reasonable, at the same time, can save the cost of the project.

Six, multi-machine chiller more flexible:

If the chiller requires a large cooling capacity, it is not suitable to choose a single machine, should adopt multi-mechanism cooling, the electric machine should use frequency conversion speed regulation, in order to reduce the starting power. Multiple machines can be used flexibly, not to appear "big horse car" waste of energy phenomenon.

Seven, automatic control device to ensure the whole adjustment:

At present, some manufacturers use manual way to control the air volume and air pressure adjustment, but because the control valve of air volume and air pressure are in the technical separation layer, and the ceiling is also the soft ceiling of color steel plate, basically are in the installation and commissioning of good, since then, most have not been adjusted, in fact, can not be adjusted. In order to ensure the normal production and work of clean workshop, a relatively complete automatic control device should be set up to realize the following functions: clean room air cleanliness, temperature and humidity, pressure difference monitoring, air valve regulation; High purity gas, pure water and circulating cooling water temperature, pressure, flow detection, gas purity, pure water quality monitoring.
