Discussion on the independent temperature and humidity control scheme for clean operating room air conditioning system
LIU Shuanqiang
Abstract：The traditional air conditioning system for clean operating rooms has problems such as coupled temperature and humidity control and excessive energy consumption.It is urgent to explore efficient and energy-saving control schemes.A temperature and humidity independent control(THIC)system scheme is constructed,where fresh air takes on the moisture load and the circulating unit operates in dry conditions to achieve separate control of temperature and humidity.The system configuration and air treatment process are established,and an energy-saving analysis is conducted using a hospital in Yingtan,Jiangxi Province as the research object.The results show that compared with the traditional scheme,the total cooling capacity of the THIC system is reduced by 46.2%,the reheat capacity of the circulation unit is reduced by 88.7%,and the annual electricity consumption of the first-level operating room is reduced by 52.3%,with a carbon dioxide reduction of 3.2 tCO2 per year.The temperature and humidity independent control system effectively avoids the phenomenon of cold and hot counteraction,significantly improving air quality and energy-saving effect,providing a technical approach for the green development of medical buildings.
