燃气轮机的性能受到环境温度的影响，其输出功率和效率随进气温度升高而降低，这一问题可以采用进气冷却的方法来解决。本文根据天然气长输管线加压站燃气轮机排气废热及其使用场合的特点，在满足燃气轮机进气冷却要求的基础上，提出一种以R124-DMAC为工质的废热驱动的全空冷型吸收式制冷系统的燃气轮机进气冷却方案，并对此方案进行循环热力计算及性能影响因素分析。理论研究结果表明：该制冷循环切实可行，在环境温度较高时也能保证系统稳定运行和较高性能系数。

The ambient temperature influences the performance of gas turbine. The power output and efficiency of gas turbine decrease with the temperature increasing. But it can be solved by cooling the air inlet. This paper is based on the characteristics of the waste heat from gas turbine and its operation condition at natural gas pressured station for long distance pipeline. To meet the gas turbine’ s needs for inlet air cooling, a fully-air cooling mode absorption refrigeration system is proposed. The system is driven by gas turbine waste heat using R124-DMAC as working fluid. In addition, the cycle thermodynamic calculation and the performance analysis of influencing factors for this system were done. The theoretical research results show that the refrigeration cycle is feasible. The cycle can operate steadily with a high coefficient of performance ( COP) while the ambient temperature is high.
