Problems solved by technology
However, in the prior art, the high heat transfer value and low heat transfer value of the cooling circulating water flow are usually fixed values after the cooling water circulation system is constructed, and it is difficult for users or carriers to adjust them. Under different environmental and working conditions, the actual heat transfer required by the refrigeration unit or process equipment changes in real time, which makes the cooling circulating water flow provided by the cooling water circulation system very different from the actual heat transfer demand, resulting in a large number of energy waste, existing technologies can be improved

The invention discloses an energy source management method for a cooling water circulation system and relates to the technical field of cooling water circulation systems. The energy source managementmethod comprises the following steps of S1, detecting the water inlet temperature and the water outlet temperature at a water inlet pipe and a water outlet pipe of a water tank of a cooling tower by atemperature detection unit and detecting an outer air temperature humidity value; S2, uploading temperature data, water quality parameters and a heat exchange actual working condition to a storage unit to be stored by a control unit; S3, carrying out big data analysis by combining the temperature data stored in the storage unit; and S4, establishing a joint control system according to a big dataanalyzing result and regulating the actual working power of a variable frequency water pump. According to the actual heat exchange demand of the cooling circulation water, big data analysis is carriedout with reference to working conditions and a product process and a refrigerating group control system is constructed to regulate the actual flow value of the cooling circulation water within a reasonable range, so that purposes of optimized operation in unattended operation of the cooling circulation water system, reduction of energy source waste and regulation and control of heat exchange balance of supply and demand are achieved.
Description
technical field [0001] The invention relates to the technical field of cooling water circulation systems, in particular to an energy management method for cooling water circulation systems. Background technique [0002] The cooling tower realizes heat exchange with the external environment through circulating cooling water, so as to achieve the purpose of discharging waste heat and circulating cooling. The cooling water in the cooling tower is in direct contact with the external ambient air, and the cooling medium is cooled by latent heat (water evaporation) and sensible heat (heat exchange). [0003] In the prior art, the central air conditioners of users such as office buildings and shopping malls or the process equipment of factories are used as waste heat generating units, and the waste heat generating units are connected with circulating water cooling units such as cooling towers through circulating pipelines; that is, the waste heat generating units The generated wast...
