Firstly, analytical models were used to help understand the physical process and range the working conditions of the ATEST system. Then numerical models were used to prove the feasibility and the value of this new conceptual system. Acceptable system performance that can meet the heat demand was iterated in case simulation; and the economical advantages were identified by comparing it with traditional ATES systems. The ATEST system showed a greater practical value than the ATES system in: 1) solving the discrepancy between heat service and heat demand in space, and 2) crossing barriers where pipes cannot be buried. However, the system should be further modified in operation to acquire better performance and avoid practical problems.
