1.High efficiency Water-to-water heat pump adopt centralized water cooling system which is hardly influenced by ambient.Also, advanced helix pipe heat exchanger keep the system highly efficient.The cop of these units reaches more than 4.5, say, the equipment can save much cost on electricity comsuption. 2.Flexible heating(cooling) source and energy recycle funtion Users can get heat or cooling source from water-loop, ground-water or ground-loop;what is more, it can also make use of industrial waste heat, terrestrial heat, solar energy, etc, as a sort of heat or cooling source.
