Operating room is one of the places where aseptic cleaning requirements are very strict. The construction, layout, workflow and management of operating room purification project are designed around aseptic requirements. In recent years, domestic hospitals gradually choose the way of clean operating room. The operating room purification and cleaning air conditioning system controls particles in the air, meets certain biological cleaning standards, and creates a dust-free and microbial clean space to prevent infection. Operating room purification of their air conditioning duct also has certain requirements, do not want us so casual layout, the following small make up a simple take us to understand about the operating room purification air conditioning duct layout have what requirements, hope to help us.

　　(1) When the air duct of purification air conditioning in operating room is arranged, the air duct should occupy less building space without hindering production operation. It is often erected along the wall, column, floor beam or roof, and installed on the support or hanger.

　　(2) The dust removal duct of purification air conditioner in operating room should be laid vertically or askew as possible. The angle with the horizontal plane is more than 45 ° when it is tilted. When horizontal laying or inclination angle is less than 30 degrees. Measures should be taken, such as increasing the flow rate, setting up a clearing mouth, etc.

　　(3) When transporting gas containing vapor and droplets. There should be a slope of not less than 0.005. A water seal discharge pipe is arranged at the low point of the air duct and the bottom of the fan. Pay attention to the water seal height should meet the requirements of various operating conditions.

　　(4) Combustible gas pipeline, combustible liquid pipeline, electric wire and drainage pipe shall not pass through the inner cavity of air duct. It is also not allowed to lay along the outer wall of the air duct. The combustible gas pipeline and combustible liquid pipeline should not pass through the fan room purified by the operating room.

　　(5) When there is an electric heater in the air duct. The non combustible data shall be selected for the air duct within 800mm before and after the electric heater and the air duct passing through the room with fire source and other simple fires.

　　(6) The air duct shall be equipped with necessary regulating and measuring devices (such as valves, pressure gauges, thermometers, measuring holes and sampling holes, etc.) or reserved interfaces for installation of measuring equipment, and shall be located at the location convenient for operation and observation.

　　(7) The installation of air duct shall be straight as far as possible to prevent disorderly parts of pipe fittings. Elbow, tee and other pipe fittings should be properly organized, and the connection with the air duct should be reasonable, so as to reduce the force limit and noise.

　　(8) Conical or rainproof hood should be selected as the air outlet of air duct layout of purification air conditioning in operating room.
