Intermediary's water for the high temperature heat source of lithium bromide heat pump, float glass waste heat provides a large amount of low-temperature heat source.Drastically reduce electricity
The usage amount of factory's water, improves economic benefit.Power plant water and the intermediary's water recycled from float glass waste heat are unmixed, electricity
The cleaning of factory's water, intermediary's water because be in control it is too long may contain impurity, power plant water may be polluted, the circuit design side of not mixed water
Formula has ensured the reliability of system.System integrally uses three sets of heating plants, and the reliability of heat supply greatly improved, and has ensured confession
It is warm to stablize this important livelihood issues.Heat pump is utilized and widens the temperature difference, saves space, small room is suitble to use.It can either solve
Certainly because caused heat supply and demand mismatch problem when water shortage underrun overhauls in severe cold weather or float glass factory,
Also be able to satisfy user's end load it is normal when use heat demand, realize energy ladder utilize, meet the basic reason of energy-saving and emission-reduction
It reads, saves economic cost, increase economic efficiency.
