| Abstract: | Tests the refrigerating performance of the ground source heat pump system with 50-metre-deep buried underground exchanger operating intermittently in summer. Analyses the effect of system operation on underground temperature. Suggests adopting mixed system to solve the problem of thermal imbalance between summer and winter in Chongqing areas. Introducing the cylindrical heat source theory, establishes a vertical U-type heat transfer model. The simulated results tally with the experimental data. |
