Exploration of Implementation Path for the Energy Conservation and Consumption Reduction in the Hospital's Centralized Air Conditioning System
By exploring the efficient machinery-room design of the centralized air conditioning system in a newly built hospital building,the level 1 energy efficiency design indicator with an annual average energy efficiency ratio (EER) of no less than 6.0 is proposed. The path of achieving the efficient machinery-room is explained briefly. By adopting energy-saving management measures such as intelligence,institutionalization,specialization,and refinement,the operation and maintenance management are being performed in the existing centralized air conditioning system of the hospital. The building's electricity consumption has decreased by 2.66％ year-on-year,and the hourly electricity load has decreased by 53kW,despite a significant increase in medical business volume. Finally,by simulation calculations on the frequency conversion transformation of central air conditioning unit,which is the highest proportion of energy consumption in the existing centralized air conditioning system of the hospital,it is found that the energy efficiency of the air conditioning unit after frequency conversion transformation is expected to be significantly improved,and an annual energy saving of 99545.4kWh will be achieved,with an energy saving rate of about 19.44％ and a reduction of about 56.77tons of carbon dioxide emissions.
