| The coach station is an important part of traffic hubs in China.At present,the design of coach stations focused on its transport capacity and layout planning,while the energy consumption was less considered.In this paper,based on the field survey,data analysis and energy consumption simulation,the current energy consumption status and main influenc factors of coach station in severe cold and cold zones are determined,which was of great significance for promoting energy-saving work of traffic hub buildings.Firstly,the energy consumption of 13 coach stations were investigated in severe cold and cold zones and the basic information such as building information,operation situation,the main equipments and energy consumption bills were obtained.The comprehensive energy consumption per unit area of coach stations in cold and cold regions ranged from 41.55kWh/(m~2·a)to 128.08kWh/(m~2·a).The average energy consumption of building air conditioning system,heating system,lighting system and electrical equipment system of the samples were 7.36kWh/(m~2·a),43.63kWh/(m~2·a),6.03kWh/(m~2·a)and 20.97kWh/(m~2·a).Meanwhile,a thermal environment field test of the waiting hall in summer was conducted and the thermal comfort of the passengers was investigated by questionnaires.The netural temperature suited for coach stations in severe cold and cold zones were 27.3℃and 28.0℃,and the accepted operating temperature range of passengers were 26.8~29.6℃and 27.0~29.6℃,respectively.Secondly,the correlation analysis and multiple linear regression analysis of the power consumption of the first-class coach station were carried out by the use of the statistical software SPSS.The influence sequence of each factor on the power consumption per unit area and the total building power consumption were determined and the regression prediction models were also established.It was found that per capita GDP,climate regions,the form of air condition system and heating system were significantly correlated with the unit area power consumption of the coach stations,and the number of staff,building area and the form of air conditioning system were significantly related to the total power consumption of the coach station.Finally,based on the relevant design standards,researches and current situation of coach stations,the energy simulation model of coach station was proposed.Building energy consumption were simulated and analyzed by orthogonal test and eQuest simulation software.The influence order of factor on energy consumption of air conditioning system,heating system and comprehensive energy consumption was determined.And the energy-saving potential of applying daylight illumination,setting heat recovery and the form of air condition system and heating system in severe cold and cold regions were studied. |
