摘要
本文设计了翅片管降膜冷凝器,将其改装于家用空调器上(额定制冷量2650W)进行实验研究,并在标准焓差室中进行四个制冷工况下的对比实验,在系统稳定运行时使用热像仪对冷凝器翅片表面的温度进行热像图摄取。使用了降膜冷凝器的改良机有三组充灌量,分别为:550g、650g、750g,而用于对比参照测试的标准机充灌量为出厂标配的1050g,测试实验数据表明:充灌量达到650g时,改良机的性能与标准机相当,即650g充灌量为最佳充灌量。相比于标准机,降膜冷凝器的使用可以有效减少制冷剂的充注量。
A falling film condenser with finned tube has been proposed and employed on air condition(cooling capacity:2650W) in this paper,the characteristics of heat transfer performance of condensers were experimentally studied in enthalpy different laboratory under four refrigerating conditions,and the infrared thermography has been used to measure the temperature of the surface of condensers' fins while the system worked steadily,the total refrigerant charging quantity of improved machine which employs falling film condenser increased from 550 g to 750 g by 100 g,while it of the standard machine which was on sale was1050 g,The experimental data indicated that the performance of improved machine was similar to it of standard machine when it's refrigerant charging quantity reached 650 g.As a conclusion,the employment of falling film condenser can reduce refrigerant charging quantity effectively compared to standard machine.
