双变或全变式多联机空调系统
Multicouple unit air conditioning systems with double or total variable volume compressors
摘要：
比较了一般变频式多联机系统和双变式或全变式多联机空调系统在结构、组成、运行和容量控制工作原理等方面的差异，理论和实践表明，后者较前者更为节能，节能幅度约为20%。

Abstract：
Compares the differences in structure, constitution, operation and work principle of capacity control between a general multicouple unit system and the multicouple unit system with doublevariable or totalvariable volume compressors. Both theoretic analyses and practice illustrate that the latter can save more energy by about 20% than the former.
