Utility model content
The purpose of this utility model is exactly that a kind of energy saving water supply device of technique cold water is provided in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of energy saving water supply device of technique cold water, it is characterized in that, comprise cooling tower, refrigeration unit, heat exchanger, user side, the first valve, the second valve, the 3rd valve, the 4th valve, the 5th valve, the 6th valve, cooling water pump, chilled water pump and water circulating pump, described cooling tower input respectively with the second valve, the 6th valve connects, output respectively with the 5th valve, cooling water pump connects, described cooling water pump is connected with refrigeration unit by the first valve, the 5th described valve respectively with the 3rd valve, chilled water pump connects, the 3rd described valve connects with refrigeration unit, described chilled water pump is connected with heat exchanger, described heat exchanger respectively with user side, the 4th valve, the 6th valve connects, the 4th described valve respectively with refrigeration unit, the 6th valve connects.
Described refrigeration unit comprises condenser and evaporimeter, and described condenser is connected with the first valve, the second valve respectively, and described evaporimeter is connected with the 3rd valve, the 4th valve respectively.
Described heat exchanger is water-water heat-exchangers of the plate type.
Compared with prior art, the utlity model has with inferior advantage.
1, owing to adopting the water supply and energy saving method of existing technique cold water, originally need open powerful freezing unit under situation winter, only need open the blower fan of cooling tower that power is less than refrigerator now, greatly saved electric weight.
When 2, if the freezing unit of water-cooled is started shooting winter, more than cooling water water temperature guarantees 18 degree, during start, cooling water tank needs steam preheating or opens electrical heating, wastes energy and troublesome poeration, and this method of supplying water is simpler, and reduces unnecessary energy waste.
