Sterile Noise Control

Due to the large vibration during operation of the large centrifugal fan, in order to prevent the vibration of the fan from affecting the surrounding environment, it is necessary to take vibration reduction measures for the fan. Damping spring shock absorber, considering the economy, small centrifugal fans can use rubber vibration damping pads to reduce vibration; install soft joints at the air inlet of the fan, so that the noise and vibration generated by the fan during operation will not be transmitted to the laboratories on each floor through the fan. When using the FRP centrifugal fan for roof exhaust, it is necessary to install a muffler at the air suction port of the fan. The muffler is a muffler equipment designed to reduce the noise level of the laboratory exhaust gas exhaust system. The muffler is rainproof and anti-corrosion. The overall shell is white PP sheet with sound-absorbing material inside.

The ventilation of the pharma machinery is 8-15 times/h; the wind speed in the branch pipe is 6-8m/s, and the wind speed in the main pipe is 8-12m/s; The standard is generally 0.5m/s; the outdoor noise should be controlled at 70dB(A) and the noise in the laboratory should be controlled at 55dB(A). If it cannot be controlled within this range, the end of the ventilation system must be equipped with a muffler. Decentralized air-conditioning system uses independent air-conditioning units in each laboratory. Common air-conditioning units include ceiling-type air conditioners, wall-mounted air conditioners, cabinet air conditioners, and window-type air conditioners. Ceiling-type air conditioners do not occupy space and have low noise. It has excellent comprehensive performance and is often used in laboratories; window air conditioners are not recommended due to high noise; wall-mounted air conditioners and cabinet air conditioners can be used in ordinary laboratories according to the size of the laboratory area. The advantages of the decentralized air conditioning system are easy installation, flexible use, convenient management, less interference between laboratories, simple maintenance, independent control, and energy saving. The disadvantage is that there is no fresh air system, and there are many outdoor air conditioners. The distance should not be too far, and the placement location and aesthetic factors of the outdoor unit need to be considered; it is suitable for ordinary laboratories without special pressure difference or cleanliness requirements between laboratories, and is often used in construction projects with low investment and small scale. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for laboratories and clean rooms.

The local centralized air-conditioning system uses multiple air-conditioning units to control the areas with different requirements for the air environment in the experimental building. At the same time, the frequency conversion control system is used to change the energy consumption according to the change of the use area, so as to achieve the purpose of energy saving. The local centralized air-conditioning system combines the advantages of the decentralized air-conditioning system and the centralized air-conditioning system, and is widely used in experimental buildings. Centralized air-conditioning system means that the experimental building adopts the overall central air-conditioning system, and the air-conditioning of the entire experimental building is “on all” when it is turned on. Because there are usually both office areas and experimental areas in the experimental building, and there are different laboratories in the experimental area. , some problems will arise. For all kinds of laboratories that are not used synchronously, the use of centralized air-conditioning wastes a lot of energy, and it is difficult to meet the requirements of various laboratories for different temperatures and humidity, and for laboratories with different cleanliness requirements, due to the central air-conditioning system. Large, it will cause high investment; it cannot meet the different requirements of the precision instrument room in the experimental building and other laboratories; it cannot meet the different needs of the air conditioning system in the experimental area and the office area; the centralized air conditioning system uses a unified refrigeration unit, piping Uniform layout, temperature, humidity and ventilation design can easily meet the requirements of human comfort, suitable for large office areas in the building, but not recommended for comprehensive areas where experimental areas and office areas are used at the same time.
