Abstract

The invention discloses a combined heat and power generation waste heat recovery system for data center cooling and a control method. The system mainly comprises a waste heat boiler, a turboset, a condenser, a condensate pump, a shaft seal heater, a water feeding pump, 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, a cooling tower 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 cool to the data center machine room, and when the outdoor environment temperature is reduced, the water-water cooling heat exchanger is used for supply cool to the data center machine room in a natural cooling mode. According to the combined heat and power generation waste heat recovery system, the cold supply requirement of the data center machine room is met by recovering flue gas waste heat of a thermal power plant, the energy efficiency level of the thermal power plant is improved, the PUE index of the data center machine room is reduced, construction of a 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 cogeneration waste heat recovery system and control method for data center cooling, and is especially suitable for cogeneration systems 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 energy consumption scenarios to increase the in-depth recovery...
