摘要
以PR状态方程为依据,分别对CFC12和二甲醚(DME)进行了电冰箱理论制冷循环模拟计算和对比试验。试验结果表明,在不改变原冰箱结构条件下,用DME替代CFC12是可行的;在DME最佳充灌量(80g)下,耗电量为1.435kW·h/24h,较原机铭牌额定耗电量(1.45kW·h24/h)降低1.03%;为开发无氟绿色冰箱提供了一个新途径。
This paper presents a simulated calculation of the refrigerator's theoretical refrigeration cycle in with CFC12 and DME by PR state equation,and an experiment study of CFC12 in contrast to DME in the refrigerator.The results of experiment proved that it is feasible to substitute DME for CFC12 on the condition of no change of the structure of the refrigerator. On the condition of the fittest amoumt of refrigerant by the use of DME (80g).The energy consumption is 1.435 kW·h/24h,and decreases by 1.03% compared with the rated energy consumption (1.450 kW.h/24h)of the original refrigerator,and it offers a new way for developing refrigerator of environmental protection.
