摘要(Abstract):

分析了辐射供冷系统间歇运行条件下各参数的变化情况。根据空调负荷计算理论,结合辐射供冷自身特点,以南京某辐射供冷样板房为分析对象,对该系统间歇运行的有效性做出分析,并对其间歇运行的能耗进行评价。结果表明,辐射空调蓄存的残余冷量对减少预冷期的能耗起到积极作用,并存在最佳的预冷时间。
The working parameters of radiant cooling system varying with time on intermittent movement condition was presented.Bases on load calculation theory and characteristics of radiant cooling,the validity and energy consumption of radiant cooling system on the condition of intermittent movement applied to a room in Nanjing area.It was analysed and evaluated.It is found that remnant cooling of the system is positive to reduce the pre-cooling energy consumption,and there is an optimal pre-cooling point.
