One end of the heat storage device 12 is connected to the inlet of the heat using terminal 10 through a pipeline, and the other end of the heat storage device 12 is connected to the outlet of the heat using terminal 10 through a pipeline.

[0034] Specifically, a heat storage circulation pump 11 is provided on the pipeline connecting the heat storage device 12 and the heat-using end 10.

[0035] Specifically, the heat exchangers in the air-cooled chiller 5 and the water source heat pump 7 are made of high thermal conductivity materials to effectively collect the heat dissipated by the servers.

[0036] The water source heat pump 7 converts low-grade waste heat into high-grade energy and directly supplies energy to the heat-using end 10, such as the heating, ventilation, and air conditioning system of a building.

[0037] The working principle of the system disclosed by the present utility model is as follows: The air conditioner unit in the air-conditioned computer room of the data center operates, and the chilled water in the coil of the surface cooler section inside it is heated. The heated chilled water is cooled by the air-cooled chiller 5. A set of water source heat pump system 7 is added to the system.

By converting the originally wasted heat energy into valuable energy resources, it opens up new revenue channels for data center operators, such as obtaining additional income by supplying hot water and heating services to surrounding communities or buildings.

[0040] Environmental benefits: Effective waste heat recovery reduces the carbon footprint of data centers, contributing to national and even global emission reduction goals. The reduced energy consumption means less burning of fossil fuels, thereby reducing greenhouse gas and other pollutant emissions, which has a positive impact on mitigating global climate change.

[0041] Social benefits: Promoting this system is conducive to enhancing the public's awareness and support for green data centers and strengthening the social responsibility of enterprises. At the same time, through energy sharing with the surrounding community, the energy security and resilience of the community can be enhanced, promoting energy self-sufficiency within the region and forming a good social ecological cycle.
