【摘要】 本文对制冷系统的流量特性进行了深入分析,获得了整个制冷系统的流量变化特性。针对在实际过程中电子膨胀阀流通能力很难与制冷系统容量完全匹配的具体状况,研制出了使用电子膨胀阀的试验样机,并进行了流量控制试验,通过试验获得了制冷系统在此情况下的独特流量特性。分析了独特流量特性产生的原因,并对由此给电子膨胀阀控制带来的不便,提出了相应的改进措施。更多还原

【Abstract】 Flow characteristics of refrigeration system was analyzed. Since it is difficult to get a good match between the flow capacity of electronic expansion valve and system refrigeration capacity, an experimental prototype using electronic expansion valve was tested, and its flow control characteristics on the mismatch condition was obtained. The reasons this special flow characteristics was explained and its influences to the electronic expansion valve control were analyzed, moreover, some measures for improvement were presented.更多还原
