ANALYSIS ON THE APPLICATION OF ICE THERMAL STORAGE AIR-CONDITIONING SYSTEM IN SUBWAY STATIONS IN BEIJING
As Chinese economy developing rapidly, traffic problems in Beijing have become more and more serious. City subway train, as one of the means of solving traffic problems，has had great development. At the passengers’ desire for more comfortable environment, installing air-conditioning system in subway trains and subway stations has become a necessary trend. The power energy consumption of subway train is huge. How to change the electro-mode reasonably and reduce power energy consumption has been an urgent problem need to be solved. This paper calculates the cooling load of a subway station in Beijing and compares a conventional air-conditioning system with ice thermal storage system in first cost, running cost and power energy consumption. Furthermore, this paper analyzes the feasibility that applies air supply under low temperatures in the subway. It decreases operating electricity consumed and reconciles the contradiction electric shortage. The results show that it is feasible to apply ice thermal storage air-conditioning system in the subway station and could reveal an energy saving potential.
