Aiming at the problem that energy dissipation and?human resource waste caused by flow regulation in parallel cooling branch pipes,this paper provides an energy saving technique of cir?culating water system which can regulate temperature automatically. It's core is intelligent temperature control valve that combines elec?tric proportional valve and the PID control system. The temperature of water in any cooling branch pipe is set independently according to the cooled body and every intelligent temperature control valve is controlled by itself. The flow in any cooling branch pipe is regulated automatically based on the ambient conditions and production load, and never interplay. The energy saving technique was applied to ener?gy saving reconstruction of a cooling circulating water system in some chemical plant,and it made the system more intelligent,need less workers,lead to more accuracy temperature control for cooled body, have a prominent energy saving effect.
