The diffusers shall be concentrated to provide an airflow pattern over the patient and surgical team. The area of the primary supply diffuser array shall extend a minimum of 12 inches beyond the footprint of the surgical table on each side. No more than 30 percent of the primary supply diffuser array area shall be use for nondiffuser uses such as lights or gas columns. Because the greatest amount of the bacteria found in the OR comes from the surgical team and their activities during surgery, turbulent air patterns within an operating room are to be avoided.
To provide a unidirectional air pattern, laminar flow diffuser arrays Group E , sized to introduce air into the room at low velocities of maximum face velocities of 20 to 35 fpm, are used. The velocity is low enough to prevent secondary entrainment of room air into the supply pattern. Two filter banks for air handling serving ORs are required.
Filter bank number 1, MERV 7, is located prior to any cooling coils, while filter bank number 2, MERV 14, is located downstream of any fan, coil, or drain pan. Current design practices for air distribution in operating rooms rely heavily on research by Memarzadeh and Manning.
Early research in the late s by Kenneth Goddard started the industry dialog about total air changes needed in operating rooms to minimize post-operative infection rates. Note on the curves that increasing air changes per hour from 20 to 25 reduces bacteria colonies per cubic foot of room air from 3. These curves have been used as one reason for supplying up to 40 air changes per hour in heart and orthopedic operating rooms. As specialists we know the BRSIA regulations in great detail and can let you know all the information to ensure that you can conform to these requirements.

The 7 codes include: Code A is the air distribution system which deals with all the necessary stages that need to commission and air distribution system. A range of preparatory checks need to be made to ensure that it meets air flow regulations.
Code B involves boilers. The development of boilers have increased over the recent years which is why the second code has been reviewed a number of times and had various changes made. We take into account the changes in technology when looking into the boiler commissioning. Code C looks into automatic controls which means observing and testing whether the control systems are effective. This code provides up to date data and details on the controls with recommendations and advice.
Commissioning lighting is crucial for the requirements of new buildings and major refurbishments under the Building Regulations Part L2. The lighting commissioning code is one of the newest codes which looking more into the construction process where the decisions are made. Code M is for commissioning managers, engineers and other designers and installers.
- Air Distribution.
- Navigation menu.
- New Plane Geometry.
- Solidarity Divided: The Crisis in Organized Labor and a New Path toward Social Justice.
This is a crucial code to ensure the safety within the building and that everything has been commissioned correctly, at the appropriate times. This will overall help improve the performance of the facilty. Code R is the penultimate code which is for the refrigerating system. This code is also a feature that can define the process which need to be carried out. Code W is the final code which focuses on water distribution systems.
This offers the process to commission buildings and their systems correctly. It is a safe, high quality and comfortable environment for energy. This presents commissioning as reccommendations and guidance.
