Energy Consumption Simulation Of Clean Operating Department Air Conditioning System Based On DeST

Medical level has relation to people's life and health.With the rapid development of science and technology,as well as the demand for medical level improved continually,more and more advanced medical technology and equipment are widely used in the operating room.The advanced technology and equipment can effectively improve the medical quality and control the risk of infection.Meanwhile,the problem of the energy consumption of air conditioning system is becoming more and more serious in the operating room.The energy consumption of air conditioning system in the operating department of hospital in China is very large,which the main reason is that operating room air conditioning system has the characteristics of small relative load,large air volume and long cooling time,etc.Therefore,according to the characteristics of the different operating room,choose the right means of air supply and supplying air volume has important significance to research air conditioning energy saving of clean operating room.This article selects a hospital operating department in Linyi city as the research object.On the base of confirmed the function of each room in clean operating department and parameters of architectural structure,utilize simulation software DeST to calculate and evaluate the energy consumption of operating room for grade I and?under different ventilation state.The main contents of this article are as follows:(1)Introduces the research background of this article and the development of clean operating room;Besides,this paper also expounds the study about operating room air distribution and air volume by a group of international and domestic academics,and proposes the main research contents.(2)Elaborates the influence factors of operating room air conditioning system energy consumption and the common analysis method of annual energy consumption.This thesis choose DeST as simulation platform to analyze energy consumption of HVAC in clean operating department.(3)The physical model are established in DeST through certain the functional characteristics of operating department and code requirement about the design of operating room.Combine the outdoor meteorological parameters of Linyi area,the changes of annual air conditioning load and cooling or heating load index are obtained through simulated calculation.(4)Reasonable system partition is the basis of air conditioning energyconsumption calculation.Selects the appropriate cold and heat sources as well as air conditioning scheme according to the load situation.Analysis the change of the annual energy consumption in operating department and the growth rate of energy consumption generated by the increasement of section wind velocity or air circulation ratio.(5)The COP of chiller and coefficient of energy consumption(CEC)are adopted to evaluate the energy consumption of HVAC in this clean operating department.In the end,energy-saving measures are put forward.
