【摘要】 本文首先利用生命周期成本法比较了集中式与分散式这2种不同形式的地源热泵系统的成本,包括管道系统、循环泵的初投资以及每年泵能耗的费用。而后对西安市某商场建筑进行了成本计算,结果显示集中式泵系统的生命周期成本比分散式系统高17.4%。更多还原

【Abstract】 In this paper,methodology of life cycle cost(LCC) was used to compare the costs of central and distributed ground source heat pump(GSHP) systems,including the initial cost of pipe system and circulating pump and the annual cost of energy consumption.And then,the cost of a commercial building in Xi’an was calculated,results indicated that LCC of the central system was 17.4% higher than that of the distributed one.更多还原
