摘要
本文主要介绍了日本东芝开利公司在新世纪初开发成功并已上市的使用R4 10A作为制冷剂的商用变频柜式空调机系列。该系列空调机的特点是采用了先进的直流变频机带动的双缸转子式压缩机 ,与原来使用R2 2的变频压缩机相比 ,重量减轻 1/ 2～ 2 / 3,压缩机效率提高 2 0 %～ 2 5 % 。
This paper introduces the new series commercial use air conditioners developed by Toshiba Carrier Corporation The new series air conditioners have greater energy efficiency than ever before For ozone layer protection,the new refrigerant R410A(HFC) has been adopted to this series for the first time in the commercial air conditioner field In order to improve the energy efficiency,the'Dc twin rotary'was developed to operate at optimal levels,using R410A Comparing the compressor model with the former model,its weight is 1/2～2/3 lighter,its energy efficiency is 20%～25% higher It means that,the energy saving of new series air conditioners is in evidence
