摘要
目的:基于优化性能和降低能耗的需要。我们在每一型号空调器的设计开发阶段,深入地剖析各个状态点的相变过程,挖掘出深层次的潜在的热力规律,力求使得整个制冷系统处于最佳经济点上运行。方法:采用热工计算和实验相结合的方法。根据某一型号空调器的配置,建立其模型。将各测试点的性能参数绘制成压-焓图,结合压缩机性能曲线图,通过详尽的热工计算,与大量的实验数据对比分析后,由最初的制冷循环1,逐步更替到循环2,循环3,直至优化匹配到理论上的最佳循环4,再通过实际的对策实施(有些措施相互间本身就存在着一定的矛盾性)——最大化地逼近循环4,最终达到我们可以接受的循环5。结论:解决了高效EER值和经济成本之间的动态平衡问题。企业在倡导节能空调,降低能耗的同时,又能很好地、有目的地控制材料成本,力求利润的最大化。为化解这一矛盾,找到了一条科学的途径。
Purpose: Based on meeting the optimization of the refrigerating circle and saved energy, we have thoroughly analyzed the phase change of all status points and explored the complicated and potential thermo-property during the each model unit design. It caused making the refrigerating circle lives in the best economical employment point. Measuring: Applied to combining the thermo-calculate and experimentation. We set up the model according to the configuration of a certain model air-conditioner. And then, we plotted the Log(p)-h graphic with the data from those status points. With the curve of the compressor performance and detailed thermo-calculate, after compared to the data which got from the lab, we have updated from the original circle 1 to the circle 2 and circle 3 step by step, until got the circle 4 which is the best circle in the theory. Then we try our best to close the circle 4 with many actual way (a few way are a certain inconsistent each other). Finally we got the circle 5 which be accepted. Conclusion: Solved the dynamic balance problem successfully that high E.E.R and economical employment. The saved energy air conditioner is improved at enterprise actively as well as it should control material cost adequately and purposely for obtaining maximum profit. It is found a scientific approach to resolve the inconsistency.
