Optimization scheme of air conditioning system of clean operating rooms based on annual energy consumption

Takes the purification air conditioning system of the operation department in Chongqing as the research object. Use the psychrometric chart to draw the scatter point distribution diagram of outdoor air state parameters throughout the year, which is used to analyse the climatic characteristics of Chongqing area. In order to analyse the economics of the air conditioning scheme, based on the annual energy consumption of the air conditioning system, uses the annual power consumption per unit area as the economic evaluation index, and elaborates the calculation process of the annual power consumption per unit area of the first-level operating room. Analyses the influence of indoor design temperature and humidity on the energy consumption of air conditioning, and finds that the influence of relative humidity on energy consumption is much greater than that of temperature. Therefore, in Chongqing area, under the premise of meeting specifications and sanitary requirements, increasing the design value of indoor relative humidity is an effective energy saving measure.
