抽水蓄能电站地下厂房水冷空调系统改造

The Transformation of Water-cooled Air-conditioning System in Pumped-storage Power Plant Underground Powerhouse

通过对某抽水蓄能电站地下厂房水冷空调系统的研究,利用现有设备,对地下厂房水冷空调系统进行了改造,并通过热量计算,验证了改造的可行性。以某抽水蓄能电站下水库深层水(水面以下50m水温常年保持约9℃)替代原由冷水机产生的冷冻水作为地下厂房通风空调系统制冷剂,较好满足了设计要求及实际需要,不但全面增强了地下厂房通风空调系统运行可靠性,还大幅降低了该系统运行成本。

Through the study of a pumped-storage power station underground powerhouse water-cooled air-conditioning system,underground powerhouse water-cooled air-conditioning system has been modified by use of existing equipment. And by calorie counting,the feasibility transformation has been verified.The pumped-storage reservoir deep water (water temperatures at 50m below surface always keeps about 9℃) replaces chiled,better meeting the design requirements and actual needs, which not only fuly enhances the underground powerhouse ventilation and air conditioning system reliability,but also signifi cantly reduces the operating costs of the system.
