Filter selection method for central air conditioning system in public buildings: graphic method

Air filters are the main equipment to reduce the indoor particle pollution, but there are many problems in engineering design. To facilitate the equipment selection and checking calculation, combing the theoretical calculation and practical method, gives the graphic method for filter efficiency calculation under the typical conditions in some public buildings. Presents the concrete use steps and use methods, analyses and proves its rationality. Confirms the feasibility through an engineering example.
