摘要：
The performance of a heat pump with CO2 trans-critical cycle was experimentally investigated for the utilization of low temperature geothermal resource. The principle and characteristics of the system were discussed. Through the simulating experiments, the means of optimizing the operating parameters to improve COP (coefficient of performance) was deducted. The theoretical results agree with the experimental data basically.
