Solar Energy Heating System Integrated Control Device and Control Method using thereof

摘要

PURPOSE: An integrated control device for a solar heating system and a control method with the same are provided to reduce the consumption of fuel by an auxiliary boiler as the heat stored at much lower temperature than the supply temperature of heating circulation water is used. CONSTITUTION: An integrated control device for a solar heating system comprises a heat storage tank(200), a heat circulation pump(500), an auxiliary boiler(300), a three way valve(600) for return water, a three way valve(600-1) for supply water, and an integrated control unit. The three way valve for supply water braches from a supply pipe installed between the heat storage tank and the spot that a branch pipe is joined to a supply pipe. The three way valve for supply water is installed at the inlet side branch point of a pipe bypassing a boiler. The integrated control unit controls the auxiliary boiler heat, the circulation pump, and the three way valves by measuring the temperature of the heat storage tank and outlet of a heating space.
