Abstract

The embodiment of the invention discloses a method and device for determining a cold source control parameter, equipment, and storage medium. The method comprises: acquiring current and historical values of freezing parameters of a freezing side in a cold source system; acquiring a plurality of alternative cold source control parameter value sets according to the current and historical values of the freezing parameters, historical values of cooling parameters of a cooling side in the cold source system, a refrigerating capacity balance relationship corresponding to the cold source system, anda refrigerating parameter function model corresponding to the cold source system; and screening recommended control parameters of the cold source system from the alternative cold source control parameter value sets according to freezing side power consumption and cooling side power consumption corresponding to all alternative cold source control parameter value sets. Therefore, while correct operation of other associated devices is not affected, the optimal control parameter value can be determined based on the own current characteristics of the cold source system.

Description

technical field [0001] Embodiments of the present invention relate to refrigeration technology, and in particular to a method, device, equipment, and storage medium for determining control parameters of a cold source. Background technique [0002] Data centers consume a huge amount of power in the entire IT industry. How to reduce data center energy consumption and improve equipment operation and maintenance efficiency is of great significance for energy conservation and emission reduction. The intelligent exploration of data centers with the goal of high efficiency and low energy consumption is a hot spot in the industry today. [0003] The HVAC system of the data center is generally cooled by the cold source system in the plate replacement mode. In the prior art, the parameter control of the cold source system in the plate replacement mode is generally based on the single-point feedback control of PID control (proportion, integral and differential, proportional, integral ...
