Summary

In this paper, a new evaporative condenser with an annular elliptic finned tube heat exchanger was introduced and some of its main performance parameters were simulated. For comparison, the actual operating parameters of the round finned tube evaporative condensation air conditioning system using in a subway station were also measured and simulated. This paper provides a reference for related researches on the actual operation of subway stations. Meanwhile, the heat transfer performance of the annular elliptic finned tube heat exchanger was compared with the round finned tube heat exchanger by numerical simulation. The results showed that the annular elliptic finned tube heat exchanger had a smaller air resistance and a larger heat transfer coefficient. Besides, the new annular elliptic finned tube proposed in this paper could increase the COP of the air conditioning system by roughly 5% to 17%, and the energy consumption is reduced by about 8% to 22%.
