Study On Building Energy Consumption And Thermal Comfort Of Ice Rink

Since China obtained the qualification to hold the Beijing Winter Olympic Games in2022,the attention of ice sports has increased year by year,and the number of ice rinks has also increased,but it also brings a lots energy consumption problems.Meanwhile,the comfort requirement of indoor skating rink is getting higher and higher.Energy saving and thermal comfort have gradually become the focus of ice rink architectural design.An indoor ice rink in Beijing was selected as the research object.First,the DeST software was used to study the effect of different insulation thicknesses and different ceiling materials on the energy consumption of the ice rink,and combined with economic factors to give an energy-saving type.Design parameters of the ice rink.Finally,the Airpak software was used to simulate and compare the indoor wind speed,temperature,air age,PMV-PPD of the energy-saving ice rink and the original ice rink.The results show that when the thickness of external wall insulation layer is 60 mm,the thickness of roof insulation layer is 85 mm and the ceiling material is vacuum plated aluminum plate,the total load of air conditioning in the ice rink is 2939778.72 k W·h,which is 58879.28 k W·h lower than that of the original type.The thermal comfort of the energy-saving ice rink is improved compared with the original ice rink.The average PMV of the audience area on the left side of the ice rink decreased from 0.20 to 0.04,and the average PPD decreased from 7.19 to 6.32;The average PMV of the upper audience area decreased from 0.15 to 0.04,and the average PPD decreased from 6.13 to 5.75;The average PMV of the inclined audience area decreased from 0.46 to 0.06,and the average PPD decreased from 10.52 to 5.17.To sum up,appropriately increasing the thickness of the insulation layer of the enclosure structure outside the ice rink and selecting the appropriate ceiling materials can save energy consumption of the ice rink and improve the indoor thermal comfort.The conclusion of this study is helpful to improve the understanding of energy-saving and thermal comfort for the designers of ice rink,and to provide references for the designers of ice rink.Figure 41;Table 29;Reference 60...
