A Hospital Building Energy Audit And Energy Saving Measures In Anhui Province

At present,the monitoring and recording of energy consumption rely only on the staff of logistics management.If we need to evaluate the energy utilization efficiency,find the direction of energy saving,and explore energy saving potential in the hospital,an energy audit needs to be carried out.Because of the complexity of the energy consumption,the energy saving measures proposed by the hospital often depend on the auditor's daily qualitative experience,which lacks quantitative verification and comparison.In the process of field investigation,we found that there were some problems,such as deficiency of the partial subentry data,irrational data,and the contradiction between the subentry data.Aiming at the above-mentioned problems,this project should be put forward which uses energy simulation software to assist the hospital's building energy audit work.After setting each parameters in the simulation software referring to the actual survey data and correcting the model,energy consumption model of energy audit based on energy saving potential was established.In order to explore the effect of energy saving of night ventilation technology in transition seasons,we set diverse aeration strategies,distinct night ventilation rate,different air change time quantum and other three kinds of research ideas.Through the comparison of the eigenvalues of DEST simulation software output,the energy saving effect and potential can be verified respectively.Research has been discovered that using night ventilation technology can effectively reduce the indoor temperature in summer of hot summer and cold winter area,meanwhile,improve indoor comfort.What we should pay attention to the application of night ventilation technology is to set the appropriate times of ventilation without using it earlier;Furthermore,via the simplification of the model,the calculation time can be effectively shorten and the efficiency of the simulation software can be improved.
