Through the engineering technology of various facilities and strict management, so that the indoor particle concentration, air flow and pressure control in a certain range, the room is called the clean room. The hospital uses air cleaning technology as the main guarantee condition, so that the number of dust and bacteria in indoor air meets certain standard of hospital room, that is, the hospital clean room.
Air filtration technology that uses air to block certain particle size and bacterial particles is used to match the airflow organization and indoor pressure gradient control with certain air volume or wind speed, so that the number of indoor particles maintained at a certain level, that is, air cleaning technology. The hospital clean room should design flow and air flow according to the specification of the clean room and the characteristics of various clean rooms. Pay attention to people, logistics procedures, air flow organization form to avoid cross infection, temperature and humidity control and so on. The clean room is a system with large area and high energy consumption. So the rational selection and allocation can achieve the desired goal.
The hospital in the design stage of the construction and reconstruction of the study, fully analyzed the choice of reasonable clean room, clean the configuration for the corresponding auxiliary room for housing, need to occupy the construction area, so in the design stage to consider the space and reasonable position, but also to avoid late clean room layout. It also causes difficulties for the maintenance and maintenance in the future, and can not give full play to the function of the clean room.
The air conditioning system in hospital clean room, according to the characteristics of it in order to use hot and cold confrontation, the corresponding cleanliness is provided with a multistage filter, increase the resistance of the system, it is a large energy consumption system. China's green hospital building evaluation standard puts forward "for clean operation Department and other clean air conditioning systems, the technical measures are used to reduce the electric reheat power by 50% than the primary air return system." Opinions.
The application of clean technology in the pharmaceutical industry: (1) in addition to limiting the size and content of the dust particles in the air, there is a clear limit to the number of biological particles (the number of bacteria). (2) the hospital in accordance with the conditions to use the corresponding clean technology to prevent bacterial infection in the air, to play an environmental protection role in the treatment. (3) medical science experiments should also have a clean environment for experimental animal husbandry, genetic engineering and other subjects, in order to achieve effective results.
