【摘要】 以大厂县民族宫为例介绍文化宫类建筑的暖通设计要点。结合全年动态空调逐时负荷计算结果,考虑建筑负荷率对系统COP的影响,比较分析土壤源热泵系统与常规冷水机组+市政热网系统的经济性,结果表明土壤源热泵运行费用较低,经济性优于常规冷热源。并对建筑内部某中庭空间进行了气流组织模拟,模拟结果指出高大空间采用喷口侧送+地板供暖的方式,在保证室内舒适性前提下,可以降低送风温差,达到较好的节能效果。更多还原

【Abstract】 This paper takes Dachang Palace of Nationalities as an example to introduce HVAC design of cultural palace buildings. With whole year hourly dynamic load,taking the influence of building load rate on system COP into account,an economic comparison on GSHP and regular water chiller + municipal pipe network indicates that GSHP has lower operating costs and better economy,which simulates the air distribution of the hall. The result shows that using nozzle side air supply and radiant floor heating for hall can reduce supply air temperature difference and achieve better energy-saving effect under the premise of the maintained indoor comfort.更多还原
