摘　　要：通过对一台轻型商用单元式空调机组在特定工况下的试验研究,分析系统压力、温度、运行状态以及冷冻油物理参数等在不同制冷剂充注量125%,100%,75%,50%,30%,25%和20%下的变化,提出机组在不同制冷剂充注量下的运行结果和潜在隐患。通过建立模型,分析机组在不同制冷剂充注量下的机组制冷能力、能效比EER和综合能效比IEER的变化,分析因综合能效比IEER变化引起的运行费用变化,提出潜在的运行费用风险和泄漏故障因素。研究结果对合理使用制冷剂充注量、改善机组可靠运行、降低使用费用具有参考价值。Through the experimental research on one light commercial unitary air-conditioning unit under specific conditions,the system parameters variations of pressure,temperature,running state and refrigerant oil properties are analyzed under different refrigerant charge level of 125%,100%,75%,50%,30%,25%和20%.The running results and potential hazard for the unit are proposed.By means of computer modeling,the variations of cooling capacity,EER(energy efficiency ratio)and IEER(integrate energy efficiency ratio)under different refrigerant charge are analyzed,as well as the variation of operation cost due to the change of IEER.Besides,the potential risks of unit operation cost and leak failure factors are put forward.The study results provide a good reference to using the refrigerant charge amount,improving the reliable operation and reducing the use cost.
