Research on Temperature Control of Hospital Operating Room under Near Comfortable Conditions

Abstract

Air temperature has a significant impact on human thermal sensation. It directly affects the heat exchange between the human body and the environment. It is the most important factor in the PMV index that affects human thermal sensation. Clothing thermal resistance is also one of the factors that affect human thermal sensation PMV. In the operating room of a hospital building, because the clothing of the operating staff is different from that of the ordinary office environment staff, the corresponding clothing has different thermal resistance values, which will directly affect the design temperature setting of the operating room. Close to the comfort zone, when wearing surgical gowns, through Matlab programming, the relationship between the PMV value in the operating room and the indoor set temperature and air flow rate is explored in detail, in order to improve the working environment of the operating room personnel and the energy saving of the operating room air conditioning system Provide a reasonable basis.
