Refrigeration method utilizing natural cold source, energy-saving system and storage medium

Abstract

The embodiment of the invention provides a refrigeration method utilizing a natural cold source, an energy-saving system and a storage medium. The current critical wet bulb temperature is calculated according to the obtained current IT equipment load of a data center and basic parameters of a refrigeration system, and when the current outdoor wet bulb temperature is smaller than the current critical wet bulb temperature, the predicted outdoor wet-bulb temperature after a first preset time is obtained through prediction of an environment parameter model obtained through pre-training, and when the predicted outdoor wet-bulb temperature after the first preset time is also smaller than the current critical wet-bulb temperature, it is indicated that the starting condition for refrigeration through the natural cold source is achieved, the energy-saving system sends a natural refrigeration mode starting message to the refrigeration system to instruct the refrigeration system to start the natural refrigeration mode, so that the critical wet bulb temperature of the starting condition of the natural refrigeration mode is dynamically adjusted according to the actual IT equipment load of the data center, and the actual situation of the data center is considered; the utilization of the natural cold source is realized to the greatest extent, and the available time of the natural cold source is prolonged.

Description

technical field [0001] The application relates to refrigeration technology, in particular to a refrigeration method using a natural cold source, an energy-saving system and a storage medium. Background technique [0002] With the rapid development of technologies such as big data and industrial Internet, the number and scale of data centers are gradually increasing. The computer room of the data center needs to be cooled all the year round. Different HVAC systems can be used to cool the computer room to reduce the temperature of the computer room. Equipment is better protected. [0003] At present, commonly used HVAC systems include air-cooled air-conditioning, chilled water systems, and water-side natural cooling systems. In the water-side natural cooling system, the chiller is normally turned on for cooling in summer, and the cooling tower is used for cooling in other seasons. The water and the chilled water in the end of the air conditioner exchange heat through the plat...
