为了提高房间空调的整体性能，系统的对家用空调器各部分进行深入的研究，本课题设计和建立了空调换热器综合实验台。该系统集测试室工况系统、空气测量装置、制冷剂循环系统、恒温水装置以及电气控制及参数测量系统于一体，配合多种高精度的测量手段、完备的数据采集和处理功能，以及先进的控制系统，是一个综合性、多功能的实验台，可以为家用空调器多方面的研究提供实验平台，也是本课题的实验装置。

制冷剂循环系统是试验台的主要部分，主要对制冷剂进出口温度、压力以及制冷剂流量进行控制和测量；通过对制冷剂流量的控制来控制过冷度或过热度，从而控制两相区的长度；为不同物理、几何参数的换热器实验提供需要的实际工况。

论文先从理论角度建立冷凝器计算模型，并编制计算程序。通过理论计算，得出不同工况下冷凝器的换热性能。

用实验手段测量不同接触热阻冷凝器在相同工况下的换热性能参数，经过分析达到对工业生产有指导意义的结论。测量了同一冷凝器不同进口空气温度、空气流量和不同制冷剂进口温度、压力以及制冷剂流量的情况下的换热性能参数，进行分析和计算，得到了换热系数和空气侧雷诺数的关系，并拟合出了空气侧的传热关联式；将实验结果与模拟结果进行比较，结果显示模拟计算与实验研究结果总体规律一致，计算模型可以反映不同空气进口温度、不同流量下换热器换热量的变化规律。
