双变频压缩机并联系统及其在多联机上的应用

The System With Two Parallel Connected Variable Speed Compressors and Its Application on Multiple-split Air-conditioner

双变频压缩机并联系统是通过使用两台小排气量的变频压缩机代替传统的单变频压缩机的一种新型空调系统。经理论分析及试验验证,双变频压缩机并联系统应用于负荷变化大的多联机组时比传统的单压缩机系统能效优势明显。

The system with two parallel connected variable speed compressors is a new air-conditioner system which has two variable speed compressors in a outdoor unit instead of one inverter compressor. Through theory analyzing and testing, we prove that this system is more efficient than the lraditional system with one variable speed compressor, especially on multiple-sprit air-conditioner whose load is variable.
