全无氟冰箱的开发研究

The Development and Research of“None CFC_s”Domestic Refrigerators

本文介绍了青岛电冰箱总厂“全无氟”电冰箱的开发研究情况,描述了以 BCD-220电冰箱为例,采用 HFC-141b 替代 CFC-11作发泡剂、HFC-134a 替代 CFC-12作制冷剂后的测试试验结果,并与替代前作了对比分析,同时指出了“全无氟”冰箱开发及生产中应注意的问题。试验结果表明,替代后各项性能指标均能符合我国国标要求,耗电量值与原来水平相当,比目前国内外公布结果要好,经过改造和增加部分设备、仪器,即可进行“全无氟”冰箱的批量生产。

This paper describs the development and research of“None CFC_s”refrigerators of Qingdao General Refrigerator Factory,it also introduces the experimental results of model BCD-220 re- frigerator after using HFC-141b as foaming agent instead of CFC-11 and HFC-134a instead of CFC-12 as refrigerant.Here is given the analysis and comparison to that before substitution as well as the problems which should be taken good care during design and production of“None CFC_s”refrigerators Experimental results show that all the characteristics satisfied Chinese Na- tional Standards,the power consumption appears equally,but even better than the results an- nounced at home and abroad.Now some equipment and instrument have been modified and in- creased,“None CFC_s”regrigerators will be soon put into production in batches.
