CO_2跨临界低温地热源水—水热泵的实验研究

EXPERIMENTAL STUDY ON THE PERFORMANCE OF A LOW TEMPERATURE UNDERGROUND WATER TO WATER HEAT PUMP WITH CO_2 TRANS-CRITICAL CYCLE

研究用CO2 跨临界循环热泵系统开发低温地热资源 ,详细介绍了CO2 跨临界循环热泵系统的运行机理、装置特点、热源选取。通过低温地热源的模拟实验 ,给出实验最优工况的调节方法 ,这对开发应用CO2

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.
