Recover heat from the winter cooling tower, using turbine extraction steam as the driving heat source. A steam-type lithium bromide absorption heat pump is used to raise the temperature of the primary network return water, saving boiler energy consumption.
Use waste heat steam, process hot water, and esterification steam as heat sources for the lithium bromide unit to produce chilled water at or above 5°C, meeting air conditioning or process refrigeration needs.
Utilizing waste heat steam and hot water from the process as the heat source for the lithium bromide unit to produce chilled water at 5℃ or above, meeting the cooling needs of the process or air conditioning.
Utilizing waste heat steam, hot water, and natural gas as energy sources to drive a lithium bromide chiller, producing chilled water at 5℃ or above to meet process or air conditioning cooling needs.
