A data center integrated cooling system based on waste heat recovery and a control method thereof

Abstract

The invention discloses a data center integrated cooling system based on waste heat recovery and a control method thereof. The system comprises a waste heat recovery system, an adsorption type refrigeration system, a domestic hot water system, a heating system and a natural cold source utilization system. A backwater of the waste heat recovery system alternately enters a first second adsorption bed and a second adsorption bed of the adsorption type refrigeration system to heat and desorb. A third adsorption bed and a fourth adsorption bed in an absorption refrigeration mode alternate in connecting to an air handling unit of a data center. Backwater of the waste heat system goes through the adsorption type refrigeration, a hot water tank and a heat exchanger to be sent to the data center again to absorb heat. The flow entering an adsorption type refrigeration set and the hot water tank is adjusted by a three-way valve. The other side of the heat exchanger is connected to a heating system and a cooling tower. The flow entering the heating system and the cooling tower is also adjusted by a three-way valve. The system and method of the invention can fully utilize IT equipment heat radiation in the data center and a natural cold source, is in accordance with the requirement of China for construction a green data center and is substantial in energy saving and emission reduction benefit.

AI Technical Summary

Benefits of technology

The technical effect that this new technology solves are improved efficiency and accuracy during manufacturing processes compared to previous methods by improving productivity while maintaining consistently high quality products for customers' use or sale.

Problems solved by technology

Technological Problem addressed in this patents relating to improving thermal management within computer servers are reducing power usage while minimizing carbon emissions associated with conventional coolant cycles used in datacentres. Conventional techniques have limitations due to their slow response time compared to more advanced technologies such as fluid cooling, where they require continual heat pump operations. Liquids were proposed as potential solutions because these materials could absorb and release heat faster without consuming too much electrical power during cold periods. Additionally, solid adsors made up of organic soluble salts exhibit improved performance when exposed to hot waters at temperatures above room temperature.
