Heat transfer regulator in district heating system - regulates heat transfer station heat exchanger by existing temp. sensors

摘要

The regulator is used to regulate quantity of heat released to different branching heating circuits of a district heating system. The heat is transmitted from a single heat source. The measuring and regulating instruments for heat flow already existing at transition stations are used for heating system control and regulation. The valve (15) is adjusted by means of the outside temp. measured by temp. sensor (10). The temp. measured is converted into valve actuating signal for ensuring adjustment. Heat is supplied by fluid medium through a feed pipe which has a temp. sensor. The heat transfer station has heat exchanger (4) and heat imparting fluid is returned through return flow pipe (6) with return temperature sensor (5).
