应用水库水的水电站地下厂房空调系统全寿命周期成本分析

Life cycle cost analysis of air conditioning systems in underground powerhouses of hydropower stations using reservoir water

针对应用水库水的水电站地下厂房空调系统,建立了全寿命周期成本(LCC)的计算模型。以某水电站工程为例,对其适用的空调方案进行了LCC分析,结果表明,在22.5℃的水温下,将水库水作为空调系统的一级冷源,之后作为冷水机组的冷却水,并且不在中间层和母线洞设置局部空调机组的方案经济性最佳。对不同水温条件下的空调方案进行了LCC计算,分析了水库水在不同水温条件下的适用性。

Aiming at the air conditioning systems in underground powerhouses of the hydropower stations using reservoir water,establishes a calculation model of the life cycle cost(LCC).Taking a hydropower station project as an example,the LCC analysis of its applicable air conditioning schemes shows that at the water temperature of 22.5℃,the reservoir water used as the primary cold source of the air conditioning system,and then as the cooling water of the chiller,and not setting local air conditioning units at middle layer and busbar holes is the most economical.Calculates the LCC of air conditioning schemes and analyses the applicability of the reservoir water under different water temperature conditions.
