DESING A POSITIVE PRESSURE GENERATOR SYSTEM AT LOW COST TO REDUCE INFECTION IN A SMALL OPERATING ROOM WHICH USE A SPLIT MODULARAIRCONDITIONINGSYSTEM

Abstract

Study design creates a positive pressure low to reduce the infection in the operating room using a small modular air conditioning system in this. This research is action research by improving the design and operation of the small community hospital to a standard increase. The study found that the problems of the operation of a small community hospital. The most currently inactive have come from the fact that no doctor or nurse anesthesia. The reason, the researchers found that most patients do not adhere to a standard such as air conditioning split. The pressure inside the chamber is a negative pressure and the amount of dust particles exceeded the standard doors. The residual air in the room a lot.

Research Methods had start by exploring the problems. Then came the problems to be resolved. And then design a system that is an important factor of the operating room in order to have a positive pressure inside the chamber. With proper air flow. Reduce the amount of dust and particles, such as improving the interior smooth as possible not to have a corner or edge in the dust. Improving the door of the operating room to have a leak. Improving the ceiling is plastered smooth. Lighting ceiling flush with the inside of the ceiling. Install fresh air into the room with the air entering into the cooling coil of the air conditioner directly to lower temperatures and lower humidity. Air conditioning is a big change for the aeration system and ventilators.

          From designing and renovating. The pressure inside the chamber (Pa) from -4.5 to +5.8, The flow of air from the No 15 ACH, Temperatures from 27 °C - 31°C to 23°C - 27°C, The humidity. 71% HR decreased to 61% HR , Dust and the particles decreased, CO2 from 1,241 ppm. down to 300 ppm. The overall operation has improved the value of the benchmark and possible. The desired objectives to further improve the sound increases. The sound of the aeration system Prang and gotten bigger. The solution is to move the aeration system from the operating room more. Your air conditioner with less noise.
