The airflow shall be unidirectional, downwards, and theaverage velocity of the diffusers shall be 25 to 35 cfm/ft2(127 to 178 L/s/m2).

24、 The diffusers shall be concentrated toprovide an airflow pattern over the patient and surgicalteam.

32、ers will strive to minimize any possible deleterious effect on the indoor and outdoor environment ofthe systems and components in their responsibility while maximizing the beneficial effects these systems provide,consistent with accepted Standards and the practical state of the art.ASHRAEs short-ran

33、ge goal is to ensure that the systems and components within its scope do not impact theindoor and outdoor environment to a greater extent than specified by the Standards and Guidelines as established byitself and other responsible bodies.As an ongoing goal, ASHRAE will, through its Standards Committ

34、ee and extensive Technical Committee structure,continue to generate up-to-date Standards and Guidelines where appropriate and adopt, recommend, and promotethose new and revised Standards developed by other responsible organizations.Through its Handbook, appropriate chapters will contain up-to-date S

35、tandards and design considerations as thematerial is systematically revised.ASHRAE will take the lead with respect to dissemination of environmental information of its primary interest andwill seek out and disseminate information from other responsible organizations that is pertinent, as guides to u

36、pdatingStandards and Guidelines.The effects of the design and selection of equipment and systems will be considered within the scope of thesystems intended use and expected misuse. The disposal of hazardous materials, if any, will also be considered.ASHRAEs primary concern for environmental impact w

37、ill be at the site where equipment within ASHRAEs scopeoperates. However, energy source selection and the possible environmental impact due to the energy source andenergy transportation will be considered where possible. Recommendations concerning energy source selectionshould be made by its members
