Impact factors of air conditioning energy consumption in hospital inpatient buildings

Taking a hospital in Shanghai as an example, selects ten factors impacting the air conditioning system energy consumption, simulates the air conditioning energy consumption of a typical comprehensive inpatient building using eQUEST software, and analyses the influence of various factors on the air conditioning energy consumption. Obtains a sensitivity order of the factors by orthogonal test method, which is indoor air design temperature, outdoor air rate, chilled water temperature difference between supply and return water, efficiency of cold source, heat transfer coefficient of exterior wall, pump efficiency, shading coefficient of exterior window, fan efficiency, heat transfer coefficient of exterior window and lighting density. Proposes the corresponding energy saving measures for the main factors.
