Analysis on the application of ice thermal storage air-conditioning system in subway stations in Beijing.

Author(s) : CAI W., XIE G. Z.

Summary

As Chinese economy developing rapidly, traffic problems in Beijing have become more and more serious. The city's subway system, as one of the means of solving traffic problems, has had great development. Given the passengers' desire for a more comfortable environment, installing air-conditioning systems in subway trains and subway stations has become a necessary trend. The power energy consumption of subway trains is huge. How to change the electro-mode reasonably and reduce power energy consumption has become an urgent problem that needs to be solved. This paper calculates the cooling load of a subway station in Beijing and compares a conventional air-conditioning system with an 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 the operating electricity consumed and reconciles the contradiction with respect to electric shortages. The results show that it is feasible to apply an ice thermal storage air-conditioning system in the subway station and could reveal an energy saving potential.
