变频多联机产生过电流的原因与解决措施

Reason analysis and measure of excessive current of frequency-conversional multi-connected air-conditioning system

针对变频多联机在模块切换、制热除霜退出和回油退出时所出现的过电流现象,分析试验数据,找到产生过电流的原因,并提出解决措施,为多联机的安全可靠运行提供保障。

Excessive current is occurred in frequency conversional multi-connected airconditioning system when another module of the system starts up, the system finishes defrosting or oil return. Analyzes the experimental data, finds the reason. Further, presents the control measures to solve the problem which provides guarantee for safe and stable running of frequency-conversional multi connected air-conditioning system.
