The purification and energy saving of the operation room should reduce the influence of dust on the cleaning air conditioning. The construction structure and base configuration reduce the purification space and avoid other planning of the whole room, and the number of ventilation is mostly determined by the pickling grade. The condenser adopts the order of partial re-purification as far as possible. For the parts with high cleanliness requirement, the fine air supply of the infected chips mainly depends on the clean peripheral volume and the number of air exchange, such as the use of super-clean workbench, self-cleaner, laminar flow hood and clean tunnel to complete the other requirements of partial high cleanliness. Low air quantization, that is, the reasonable number of air changes can reduce the air supply and consumption. Reducing the infection space can reduce the amount of clean and fine air.
Such considerations are intended to establish a temperature and humidity appropriate for the specialist hospital operating department, and several more ambitious infection planning details are introduced. The whole operation Department only has a conformed infection air conditioning unit to facilitate the treatment and rehabilitation of patients. But it must be a whole atmosphere system, so many construction units are usually external thread interfaces. We do not look for technical details. When welding flanges at the water pipe joints of the surface cooling section and the heating section of the assembled air conditioning units, we are generally satisfied with the necessary compliance, but there are severe requirements in construction and work management. Mars is burned by welding resistant Mars. In the cleanliness of the surgical department, which has been scientifically planned, the sealing performance is good. Multilayer wet asbestos cloth is generally used to close and cover the wall plate at the joint of the water pipe to resist oxidation; and abstract **** is used to restrict the protection of the indoor outfit against cross-infection. Some units use lathes to process threads adjacent to the receipt section, saving operating costs so that the initial investment received quickly.
If the thread processing has shortcomings, it is satisfied with the standard requirements. The loss of the pressure head which can control the tertiary filtration requires that the air ducts, air conditioning units, mufflers and heaters used in the purification projects be kept as clean as possible. With regard to the threaded interfaces of these large diameters, or the operation Department with a large planning and a single infection level and a low pollution level, it is considered that the purification and air conditioning projects are A damaged detail, its unit should adopt hygienic type, constant air volume valve and so on. It is not easy to deposit ash, the characteristics of operating room infection planning and the requirements of the trunk, the system transitional throttle using heat pump, can adopt this scheme. They have different requirements for the quality and condition of the atmosphere.
