Hospital environment air conditioning

Laminar air flow system with an air curtain in the operating room is required. The most important droplets in the operating room environment can be contaminants and suspended particles in contact with the body and the entry of gases. Anesthesiologist pointed to the area outside the surgical environment, which has been studied by creating a suitable and air-conditioning system of quiet air flow with air curtain in the operating room and its advantages over conventional systems without air curtain.

Computational fluid dynamics method 1 has been used to model and evaluate the efficiency of this air conditioning system in three-dimensional simulation. Air speed and A certain temperature enters the room and creates a positive flow of air from the ceiling to the floor, which is one of the requirements of a proper ventilation system to prevent the concentration of contaminants in the operating room Modeling is done In the work done, using airflow distribution software in two different modes, it has been compared and it has been observed that the use of air curtain has brought the operating conditions of the operating room closer to the desired and safe conditions. And plays a major role in reducing operating room pollution. One of the most basic criteria that must be observed in the design and construction of each operating room is infection control.

Operating rooms should be designed to prevent the spread of infection into the surgical field and to prevent the spread of infection from these rooms to other parts of the hospital. In designing slow flow systems, the air moves in a straight line from the inlet to the outlet with the least mixing or turbulence. Discharge of suspended particles is relatively fast, it is possible to remove many of the limitations and supports that apply in the traditional operating room, and as a result saving time and operating غير مجاز مي باشدts can offset the high غير مجاز مي باشدt of equipment. These types of systems can enter the room horizontally or vertically. Interestingly, in the vertical system, heavy suspended particles come down with the air flow and help reduce pollution and remove them. The most effective quiet air ventilation system is when the quiet air vents are located on the entire roof It is less crowded, but in this case a high rate of air change per hour is required, which is usually around 50 to 400, so this system is usually less acceptable due to high energy غير مجاز مي باشدts and economical غير مجاز مي باشدt..

Vertical quiet airflow system there are also larger operating rooms such as orthopedic surgery and heart surgery rooms. Finding a way to create a better airflow is important..

Complex systems or too Expensive is a good solution for such operating rooms They are not for this reason Designers were looking for other ways to make the airflow of the room predictable and turn it into the desired airflow, a pasغير مجاز مي باشدe. And after leaving, of course, with less غير مجاز مي باشدt and complexity.

One of these new methods, which has achieved a relative degree of success, is the air curtain, as reported by some researchers in the ventilation system use Shutters in the middle of the roof, protected by air curtains, are a significant approach for hospitals.
