Abstract:
Objective:To investigate the hygienic condition and maintenance management of air conditioners in observation hotels， and give suggestions on reducing the risk of COVID-19 transmission from the daily use. Methods:This study selected 11 observation hotels chosen by government and 3 observation hotels chosen by large companies in Minhang District. The types and sanitary conditions of the air conditioning system were revealed through the daily supervision. Hotel staffs’ knowledge of air conditioning system and their mastery of how to use and maintain air conditioning system were surveyed through questionnaire. Results:Survey of air conditioning types showed that in 14 hotels， 12 were distributed air conditioning systems and 2 were semi-centralized air conditioning systems （including fresh air systems）. The investigation found that there was dust accumulation in the fresh air ducts in one hotel guest room， dust accumulation in the filter screen of fresh air intake in one hotel， and the sanitary problem of condensate water （without centralized discharge） in two hotels. All of 14 hotels had daily cleaning and disinfection records， but they were not perfect. The hotel health management personnel’ awareness rate of air conditioning was low， although they had a positive attitude towards the cleaning and disinfection of the air conditioning system. They could do the active entrusted testing， cleaning and disinfection of the air conditioning systems. Conclusion:The air conditioning systems of some hotels have hygiene problems， and hotel health management personnel are lack of knowledge of standard operation and maintenance of air conditioning systems. The air conditioning systems of observation hotel should be cleaned and disinfected before use. At the same time， it is necessary to strengthen the training of hotel health management personnel on the use and maintenance of air conditioning systems. So the transmission of the COVID-19 through air conditioning systems can be effectively prevented.
