) High efficiency and save energy. Comparing with single condensing unit, this parallel condensing unit can save energy over 30% because of controlling the different quantity of compressor on or off automatically.
2) Compact system. All main components including compressor, liquid receiver, the gas fluid separator, oil separator, the middle chiller and electric control panel are concentrated completely on the same frame for saving the space in the engine room; The pipeline and the electric cable consumption will be reduced a lot and the construction cycle can be short too because of the high integrated design idea.
3) Reliable running. All main parts such as valves, gauges and automatic electric parts are all recognized everywhere in the world.
4) High intellectualized design. The microcomputer will control all system automatically, the running time will be accumulated and all main protection functions such as phase fail protection, heat relay protection and high and low pressure protection are included
