摘　　要：实验研究了空调系统中室内盘管的进风量、冷冻水的进水温度及流量对室内盘管换热量、冷冻水受到的阻力、盘管风机的运行功率等参数的影响;并根据以上实验数据,分析了各主要参数对空调系统性能(主要指能耗)的影响规律。研究结果可为研究空调房间风、水系统的耦合关系提供基础数据和研究依据,对降低空调系统能耗及实现空调系统节能具有重要的现实意义。The influence of inlet airflow rate of indoor coils, inlet temperature and water flow of cooled water on heat exchange, resistonce of cooled water and fan power in coils and varieties of parameters are experimentally researched. According to the above experimental data, the influence laws of main parameters on performance of air conditioning system are analyzed; these results can provide foundational data and basis for studying coupled relations of air and water system in air-conditioned room. It is crucial to decrease power and save energy for air-conditioning system.
