Requirements of the disinfectant sanitation of ventilation systems in public places

Requirements of the disinfectant sanitation of ventilation systems in public places some central air conditioning system has many problems in public places, today is primarily concerned with market place such as hotel, among them the main problem is: excessive bacteria, dust, cleaning is difficult, high cost and the country in order to solve such problem, move forward in the central air conditioning system purification, disinfection, dust removal, sterilization, etc. It is understood that the ministry of health in 2004, the national hotel, 540 central air conditioning ventilation system health check the work report data show that according to the evaluation standard of 'standard' regulation: 1, the serious pollution of the central air conditioning ventilation system has 441, 47 of the total number of sampling. 1% 2, secondary pollution, 438, 46 of total sampling. 3, eligible 58 7%, only six of the total number of sampling. 2% of shenzhen in 2007 randomly selected above three-star hotel or hotel run more than 2 years, a total of 42 sets of air conditioning system, to take each air conditioning system, air conditioning air supply, air supply pipe surface, cooling water, condensate, detection of total bacteria, fungi, hemolytic streptococcus, staphylococcus aureus, S. aureus bacteria) 8%; 1%. 0%; 5%; 6%. 4, the conclusion shows that air conditioning air supply, air ducts, cooling water, condensate on the inner surface are detected pathogenic microbes, pollution is serious, must strengthen the treatment of cleaning and sanitation and hygiene. Data from the above we can come to, at least 80% is not pass, the situation is very serious, many people, especially the public to be precise, strict air quality for domestic and international current blasting air type of sexually transmitted diseases such as SARS, bird flu, swine flu, the ministry of the state for the public environment in each region of the central air conditioning central air conditioning, ventilation in March 2006 the printing on the central air-conditioning ventilation systems in public places health standard 'notice, such as the three specifications of air to air supply system to deal with the indicators to make strict rules and measures, including: supply health duct inner surface hygiene requirements only simple filtering, central air conditioning of air disinfection purification disinfector need to install the central air conditioning, and central air conditioning systems, to the above some of the health related requirements.
