摘要:
以广东某地铁车站为例，初步设计采用冷却塔加水冷螺杆机组空调系统。在车站主体结构已完工的情况下，欲将通风空调系统更改为蒸发冷凝直膨式空调系统。结合现场实际情况提出了可行的设置方案，并对2个系统的投资与运行能耗进行了对比分析。比较结果表明，蒸发冷凝直膨式空调系统可以大幅节能，有较好的应用前景。
Abstracts:
Taking a selected metro station in Guangdong as example, the preliminary design adopted cooling tower and water-cooled screw unit air-conditioning system. Under the circumstances where the station main structure has completed construction, the ventilation and air\|conditioning system are to be changed to the evaporative condensation direct-expansion air-conditioning system, feasible settings are proposed with respect to the actual situation on site. The investment and operating energy consumption of the two systems are compared and analyzed. The comparison results show that evaporative condensation direct-expansion air-conditioning system saves energy significantly, displaying a promising future for application.
