Shandong Xinli DC FFU filters the interior of the air inhalation through the air filter at the top of the dust-free workshop, and the clean air is sent out in a uniform wind speed, so that the clean and sterile purification effect is achieved.
In recent years, more and more engineering optimization designs have adopted the total lifetime cost index as the objective function of the optimal design mathematical model to conduct technical and economic analysis of the problem. This paper also uses this method. Based on the total resistance formula of this type of high-efficiency air filter obtained by a large number of experimental studies, a mathematical model with the minimum life-time total cost is established, and the problem is solved as the high efficiency of this type of FFU The basis of air filter design, and some practical conclusions have been obtained.
The FFU fan filter unit system is more complicated, and the control methods are also various, including computer group control, multi-speed switch control, remote control and other methods. The specific use depends on the clean plant central air conditioning system and the number of FFUs. Comprehensive considerations are carried out to select the most economical and reasonable control method and provide users with the best use plan. These three control methods have their own advantages and disadvantages, now let us analyze them one by one.
Before installing the high-efficiency filter, the clean room must be thoroughly cleaned and wiped. If there is dust in the purifying air conditioning system, it should be cleaned and wiped again to meet the cleaning requirements. If a high-efficiency filter is installed in the technical mezzanine or suspended ceiling, the technical mezzanine or suspended ceiling should also be thoroughly cleaned and wiped.
