This paper numerically simulates the indoor air-conditioning environment of 1st grade clean operating room in a hospital by use of CFD technology so as to evaluate the reasonableness of the design plan.

In order to evaluate the reasonableness of the design plan,this paper simulates and analyses the indoor air distribution in 1st grade clean operating room based on CFD technology.

Management and maintenance of clean operation room;

Schemes of air handling process for a clean operation room and their applicability;

Investigation and analysis on the dynamic status of contamination in clean operation rooms;

The use and management of cleaning operation room;

The optimum design of cleaning operation room has significance for the modernization of hospital building.

With the example of the electrical design for the operation room in a hospital,the design of power supply,electrical safety,grounding and lighting for cleaning operation room was stated in this article.

Management of clean operating room;

Numerical simulation of velocity fields in clean operating rooms based on CFD;

Analysis of field measured performance parameters of clean operating rooms;

An operating room information management system integrated with HIS,PACS,LIS and EMR systems was developed while setting up clean laminar flow operating room in our hos- pital.
