Combined cooling, heating and power system for data center cooling and control method thereof

Abstract

The invention discloses a combined cooling, heating and power system for data center cooling and a control method thereof. The system mainly comprises a waste heat boiler, a turboset, a condenser, a condensate pump, a shaft seal heater, a water feeding pump, a cooling tower, a flue gas waste heat recovery device, a steam-water heat exchanger, a drainage heat exchanger, a hot water type lithium bromide refrigerating unit, a water-water cooling heat exchanger and a data center machine room, the flue gas waste heat recovery device and the steam-water heat exchanger generate high-temperature hot water to be used for driving the hot water type lithium bromide refrigerating unit to produce chilled water to supply cold to the data center machine room, and meanwhile when the outdoor environment temperature is reduced, a natural cold source of a surface water source is used for performing supplemented cold supply on the data center machine room through the water-water cooling heat exchanger. According to the combined cooling, heating and power system, the cold supply requirement of the data center is met by recovering flue gas waste heat of a power plant and coupling the natural cold source, so that the energy efficiency level of the power plant is improved, the PUE index of the data center is deeply reduced, construction of the green data center is effectively promoted, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy, and specifically relates to a combined cooling, heating and power generation system for cooling a data center and a control method thereof, and is especially suitable for a combined cooling, heating and power generation system with data center cooling requirements. Background technique [0002] As for thermal power plants, as the country puts forward the strategic goal of "carbon peaking and carbon neutrality", thermal power plants are facing enormous pressure to save energy and reduce carbon. Thermal power plants are large carbon emitters, especially as the domestic carbon market continues to mature, the operating costs of thermal power plants have increased dramatically. On the other hand, the carbon reduction effect of waste heat resource recovery can also partially offset the carbon emissions of thermal power plants. Therefore, thermal power plants urgently need to develop new e...
