Clean operating room air conditioning system design to do these three points, clean operating room effect is better
Clean operating room is an important symbol of the development of hospital modernization, and also an important part of hospital modernization management, because it has an important impact on the patients' operation safety and specific operation effect.
It is found that the air conditioning system plays an important role in the operation and infection control of the clean operating room, and the unreasonable design of the air conditioning system will directly affect the sterilization effect of the operating room, which is very unfavorable for infection control. Therefore, in order to strengthen the specific use value of the clean operating room, it is necessary to make a scientific discussion on the design of the air conditioning system.
1、 Air conditioning system design of clean operating room
The air conditioning system of clean operating room is of great significance to maintain the clean effect of the operating room. From the current analysis, the directional air supply of the air conditioning system can effectively discharge the bacteria particles in the operating room, which is conducive to the control of the clean operating room environment. However, from the analysis of practical application, unreasonable air conditioning system design will cause air volume and direction problems in the operation of the system, which affect the environmental maintenance of the clean operating room.
Therefore, starting from the environmental control of the clean operating room, scientific analysis of the air conditioning system needs to meet the requirements, and based on the requirements of air conditioning design, this is the clean operating room air conditioning system design must pay attention to and follow the content and principles.
2、 Air conditioning system design of clean operating room
Air conditioning system plays an important role in clean operating room, so it is necessary to make a comprehensive analysis and Discussion on the design of air conditioning system in the practice of operating room construction.
1. Determination of air supply volume and air distribution
According to the current analysis, the air conditioning system design of clean operating room needs to do an important work is to determine the air supply and organize the air flow.
According to the practical analysis, there are two problems to be solved in the air conditioning design of clean operating room: one is that the air volume of high-level clean room is too large; the other is that the pollution control of key areas of operating room is not ideal under the same air volume for operating room below 1000 level.
The specific solutions to these two problems need to be considered in three aspects during the design:
The first is to break through the concept of whole room dilution and purification for all levels of operating rooms, and adopt the method of refusing to strengthen purification, so that different cross-section sizes of air supply can be adopted according to different levels.
The second is to use the clean air flow to cover the area for the class 100 or class 1000 operating room.
The third is that the ventilation rate method should be used to determine the air volume in the 10000 level and 100000 level operating rooms, so that the accuracy of the air volume will be significantly improved.
In a word, through the determination of air supply volume and the organization of air flow, the effectiveness of air conditioning system will play a more significant role.
2. Specific design of ventilation circuit
In the specific design of the air conditioning system, the ventilation path also has an important impact on the role of the system, so it needs to be considered in the design of the ventilation path.
According to the current practice analysis, in some operating room purification air conditioning system design, the problem of fresh air filtration has not been paid attention to effectively, so the fresh air often mixes directly with the return air of the air conditioning without independent filtration. The prominent problems caused by this situation are the shortening of the service life of the medium efficiency and high efficiency filters, and the significant increase of the system operation and maintenance cost The specific use of the operating room will also be greatly affected.
In order to change this situation, a filter unit with coarse effect and medium effect is set up in the fresh air passage, so that the situation of direct mixing of fresh air and air conditioning return air is improved. There is fresh air to be mixed with the return air of the air conditioner through filtration, so its influence on the filter is weakened, the life of the filter keeps stable, and the operation and use of the whole clean operating room also achieves stable and continuous increase.
3 solution to the problem of air balance
The third content of air conditioning system design in clean operating room is to solve the problem of air balance.
According to the current analysis, the pressure distribution in each area of the operating Department has a significant impact on the effect of clean operating room. To ensure a reasonable pressure distribution, not only the accurate calculation of air balance, but also the effective adjustment of air supply and return.
In the past, the air volume regulating device mainly used in the design was a manual multi blade regulating valve, but the effect of this valve in the fine regulation of air volume was not ideal, and in practice, it was more difficult to adjust and the debugging cycle was long.
Based on this problem, the adjustment device needs to be replaced. From the practical use, the self-supporting constant air volume valve can effectively eliminate the influence of the air pipe pressure on the air volume, and there is a dial for air volume regulation outside the device, so the operation is very convenient. In terms of the utilization practice of the device, its installation and utilization make the solution of air balance more concise.
Three, conclusion
To sum up, the air conditioning system of clean operating room has a significant impact on the environment of operating room, and the incorrect design of air conditioning will affect the specific function of the system, and then affect the utilization effect of operating room, so it is significant to analyze and elaborate the design mode of air conditioning system and study the specific problem-solving in the design, which is significant for the design of air conditioning system.
