Abstract：
Proposes a solution of direct expansion air conditioning system for underground railway stations and analyses the thermal performance of direct expansion air conditioning units. Considers the direct expansion air conditioning system can achieve the objective of security control. Taking a practical engineering program as an example, simulates and calculates the annual energy consumption of direct expansion air conditioning system and traditional air conditioning system, and the result shows that the energy consumption of the former is 26.9% lower than the latter.
