The invention belongs to the technical field of air conditioner equipment, particularly relates to a slag flushing water waste heat extracting type lithium bromide absorbing type cold and hot water unit and is mainly applied to the field of waste heat recovering of blast furnace slag flushing water in the metallurgical industry. The cold and hot water unit utilizes the characteristic that the boiling point of water is reduced along with reduction of the environmental pressure, by creating a negative pressure environment, blast furnace slag flushing water is subjected to flash evaporation in the negative pressure environment, the produced negative steam serves as a drive heat source of the lithium bromide absorbing type cold and hot water unit to carry out refrigerating and heating, and recovering of the waste heat of the blast furnace slag flushing water in the metallurgical industry is achieved. When the environmental pressure is reduced to about 19 KPa, the blast furnace slag flushing water at the temperatu
