Combining cooling of underground railways with heat recovery and reuse
Sustainable Cities and Society(2019)
摘要
•A combined cooling and heat recovery system for underground railway tunnels was devised.•The recovered heat was upgraded using a heat pump, and reused in a district heating network.•A model was developed to evaluate the performance of the proposed system.•Substantial energy, cost and carbon savings compared to conventional methods were predicted.•A sensitivity analysis identified a range of key factors influencing the cost savings available.
