Power saving control device of the cool water purifier and Control method thereof

摘要

Disclosed is a power saving control apparatus and method for a dual-pipe cold-water hydrant with a double pipe comprising an inner pipe through which cold water flows and an outer pipe through which a coolant flows, and a cooling module for cooling the coolant. The power saving control device of the dual pipe cold water purifier includes a cold water temperature sensing unit for sensing a cold water temperature; An amount-of-flow sensing unit for sensing the amount of water flowing; A driving unit for driving the cooling module; A display unit for displaying information; A memory for storing the control temperature corresponding to the water flow rate, accumulating and storing the water flow rate, and storing the average water flow rate; A timer for checking time; And a control unit for receiving the outputs of the cold water temperature sensing unit and the water level sensing unit and accumulating them in the memory, calculating an average water amount from the water amount stored in the memory, and stopping the cooling when the average water amount is less than the first reference amount do. In this embodiment of the present invention, the cold water can be efficiently provided while saving power, and the power can be saved by adjusting the cold water temperature in accordance with the user's use pattern of the cold water.
