Development of energy saving control system for heating system in universities

In view of the characteristics of larger heating area, higher energy consumption, longer heat supply pipeline and serious hydraulic disorder in universities, develops a building heating control device which consists of a field controllers, four temperature sensors and an electric valve. The controller performs acquisition and processing of the data from the sensors, adjusts valve opening thus the water supplied to the building automatically according to the heating requirement of different periods. And a holiday mode for the allowable lowest heating temperature is adopted in the control process, avoiding energy waste.
