[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Pipeline Project] duct hanger spacing 1, when the wind pipe hanger spacing as no design requirements, not duct insulation should meet the following requirements. For duct insulation, support and hanger spacing requirements without refrigeration room design engineering, spacing requirements in the table value is multiplied by 0.85. Support and hanger spacing spiral duct can be increased. 2, hangers shall not be installed in the outlet, the valve inspection holes, etc., so as not to interfere with the operation. Hanger may not be directly hung on the flange. 3, duct insulation is not in direct contact with the hanger, solid insulation mat should plant cooling works the same as the thickness of the insulation to prevent "cold bridges." 4, PVC duct swallow ene also uses the same steel duct branch, hanging bracket ventilation pipeline project, but generally the main hanger, bracket spacing requirements for the fabrication and installation of the table [Limited Tianjin Jinzhong Ji HVAC purification equipment company to recommend the star product - decontamination] to have very high demands. Here it is necessary to explain the clean room without windows lighting the way: (1) general lighting does not consider that it refers to specific local needs, in order to illuminate the entire area to be illuminated and set lighting. (2) This refers to the local lighting lighting to increase a specified location (such as the operating point) illumination and settings. But not alone in indoor lighting by using local lighting in general. (3) This refers to mixed lighting illumination of the work surface by the general lighting and local lighting synthetic lighting, general illumination lighting which press the "clean plant design specifications" should be 10% -15% of the total illumination, but not low dry 150LX. Units are accepted according to the area of ??the flux that is lighting unit lux (LX).
