Abstract
The utility model provides a chilled water cooling system which comprises a cooling tower, a heat exchanger and a surface air cooler. The cooling tower and the surface air cooler are respectively connected to two sides of the heat exchanger. Supply and return cooling water is guided to the heat exchanger, and chilled water is guided to the heat exchanger through water supply and return pipes. The cooling water can be used for cooling chilled water through the heat exchanger in winter. Supply and return water of the cooling water is guided to the plate heat exchanger but is not flow into a refrigerating machine, and the cooling water goes through the plate heat exchanger rather than the refrigerating machine in the circulating process. The chilled water is also guided to the plate heat exchanger through the water supply and return pipes by adopting the same method. The cooling water can be used for cooling chilled water through the heat exchanger in winter. The chilled water cooling system directly uses the cooling water of the cooling tower to cool the chilled water return water in a coating workshop in the chilled water producing process in winter without the refrigerating machine and achieves the energy-saving and environment-protecting purposes.
