1. Misconceptions of Cleanliness and Disinfection
Clean room is a physical method to remove dust and bacteria from the air to achieve the purpose of air cleanliness, while disinfection refers to chemical or physical methods to eliminate or kill pathogens and harmful microorganisms in the external environment or in the media. The construction of air purification system does not exclude the role of disinfection.
2. Purifying Misconceptions Affecting Comfort
Now many hospitals have built clean operating rooms, there are some problems, such as chest tightness, heavy odor, noise, feeling less comfortable than conventional air conditioning. These problems are mainly caused by unreasonable design in medical purification engineering.
3. Misconceptions of using traditional air conditioning system in modern medical buildings
The central air-conditioning system of modern hospital itself causes great potential pollution hazards. For the important functional departments in hospital, such as operation department, ICU, CCU, etc., try to purify the air-conditioning system, and reduce the risk of dust and bacteria entering the indoor air duct through physical filtration. For common areas, the use of fan coil system with high efficiency filters should be promoted.
4. Misconceptions of high purification cost and high maintenance cost
The overall cost of purification air-conditioning system often accounts for only 20-30% of the total cost of special room decoration and installation (except medical equipment), 30-50% of decoration and decoration (mainly the decoration grade has a great impact on the cost), 20-30% of electric and intelligent parts, and 10-20% of medical gas, water supply and drainage and fire protection parts. All the costs of building a medical purification room can not be attributed to the "purification" aspect.
In medical purification, as long as the design of air-conditioning system is scientific and reasonable, the construction quality is qualified, the proper use and maintenance can ensure that the cleanliness, temperature, humidity, pressure and other indicators can be controlled, and create a safe and hygienic medical environment, and the cost of construction and maintenance is not high.
