The Energy-Saving Design For Air Conditioner In The Maneuver Center For University Students Regarding On Various Activity Level In Spatial Sections

As a comprehensive campus public building,the maneuver center for university students contains a variety of functional spaces.In different functional spaces,users have different activity states and thermal comfort needs.In hot summer,the unified air-conditioning parameter is used to control the thermal environment in all the active spaces.In this case,not only make some space users uncomfortable,but also consume a lot of air conditioning energy.This kind of phenomenon is especially obvious in summer in the hot and humid areas.If the space with similar thermal environment needs is classified based on the user’s activity level,and the energy saving of air conditioning is considered when the thermal comfort regulation is carried out in the partition,the comfortable and efficient energy saving effect can be achieved.Therefore,this paper takes the hot-humid summer climate as the research condition,and recommends the energy-saving temperature and the corresponding range of air velocity parameters for all kinds of spaces.Finally,according to different activity space,the energysaving design strategy is put forward,and energy saving analysis is carried out with a case.For this purpose,the main contents of this paper are as follows:First of all,according to the activity characteristics,permanent functional spaces of a maneuver center for university students can be divided into: sedentary space;dynamic sitting-posture space;slightly moving space;exercise space.Then,the actual measurement and simulation methods are used to get the thermal environment conditions of all kinds of space in the current situation of the case.It can be known that if the unified parameters are used to adjust,the temperature difference of the air conditioning will be almost above 6 ℃ in the hottest month,and the refrigeration energy consumption of the air conditioning will be large.Secondly,according to the activity level of users,the functional spaces with similar thermal environment parameters can be roughly summarized,and the corresponding thermal regulation space can be divided into three parts: sedentary space(1.0 ～ 1.3 met),light activity space(1.4 ～ 2.9 met)and moderate exercise space(3.0 ～ 6.0 met).Then,according to different activity levels,spaces with similar thermal environment requirement are classified to form the corresponding thermal regulation zones.Combined with the results of existing researches and the field survey,in hot-humid climate area,the temperature parameter can be set in the sedentary space is 29℃,and the air velocity parameter range is 0.5 ～ 0.8m/s;in the slightly active space,the temperature can be set 29℃,and the air velocity is0.8 ～ 1.2m/s;in the moderate exercise space,the temperature is 30℃,in order to make the exerciser heat more effectively,in addition to the table tennis room,billiard room and other small ball room can not organize the air flow,the rest of the moderate exercise space could use fan to design the air flow.Finally,In order to verify the energy-saving effect of the maneuver center for university students before and after thermoregulation partitions according to different activity levels,a typical case in hot-humid areas is selected for energysaving design.According to the comprehensive analysis of the before and after the spatial partition adjustment of different activity levels with energy consumption of the case,when the utilization rate is 60%,the total energy saving rate is 42%,the energy saving is about 642 thousand k Wh,and the energy saving is about 321 thousand (?).It can be seen that the energy-saving effect of the comprehensive activity center in summer can be effectively improved by classifying the space according to the state of sedentary,slight activity and moderate exercise,and then adjusting the space according to the indoor comfort demand of different activity levels with the combination of fans and air conditioning.
