Problems solved by technology

[0002] In the cooling circulating water system with large temperature change, the temperature control of the inlet and outlet water is not accurate, and the energy consumption is high, and the temperature of the cooling return water in the system cannot be accurately controlled; the conventional cooling circulating water system only controls whether the temperature of the system outlet water reaches cooling Water requirements, the water supply on the cold source side is in a constant state. When the external temperature changes, the cooling capacity required by the return water side of the system is also changing in real time. Due to the inability to accurately calculate and adjust, there is a large amount of unnecessary energy in the system. consumption

Abstract

The invention relates to a small-temperature-variation combined type circulation cooling water system. The system comprises a basic circulation cooling water system and a water supplementing system and further comprises an adjusting circulation cooling water system. The water supplementing system carries out water supplementing work on the basic circulation cooling water system and the adjusting circulation cooling water system. The adjusting circulation cooling water system is connected to a return water pipeline of a cooling tower I in the basic circulation cooling water system in parallel, the temperature of return water is controlled through the function of a plate heat exchanger, a cooling water II and a water chilling unit in the adjusting circulation cooling water system are used for adjusting the water inlet temperature of the plate heat exchanger, the refrigerating capacity of the plate heat exchanger is enhanced, and a variable frequency pump is adopted in the whole system for supplying water. According to the small-temperature-variation combined type circulation cooling water system, the temperature of the return water can be precisely controlled, and the energy consumption of the system can also be reduced.
