| 摘 要： | 滑阀调节和变频调节是当前螺杆式压缩机最常用的能量调节方式。本文对具有相同设计参数的一台螺杆式压缩机在2种能量调节方式下的性能进行测试。测试结果表明：与滑阀调节的螺杆式压缩机相比,变频调节的满负荷COP有所降低,但综合部分负荷性能（IPLV）提高约14%。

| Abstract: | Slider regulation and VFD（variable frequency drive） regulation are the most commonly used modes for capacity regulation of screw compressor.The performance test is done for a screw compressor with slider and VFD.The result shows that,compared with slider as capacity regulation,the COP of the screw compressor with VFD under full load condition is decreased,but the integrated part-load value（IPLV） is improved about 14%. |
