Abstract

The invention relates to an environment-friendly and efficient energy-saving direct-fired-type lithium bromide absorption type cold and hot water unit. The environment-friendly and efficient energy-saving direct-fired-type lithium bromide absorption type cold and hot water unit is characterized in that as for the unit, a flue gas heat exchanger (17) is arranged on a smoke exhaust pipe of a direct-fired high-pressure generator first, and a flue gas solution heat exchanger (28), a flue gas solution heat exchanger dilute solution inlet pipeline (29) and a flue gas solution heat exchanger dilute solution outlet pipeline (30) are also arranged additionally. During operating of a refrigeration work condition, a dilute solution enters the flue gas solution heat exchanger to recover flue gas wasteheat, and flue gas releases heat and is discharged after the temperature decreases. During operating of a heating work condition, low-temperature circulating water of a heating evaporator enters theflue gas heat exchanger to recover the flue gas waste heat, the dilute solution enters the flue gas solution heat exchanger to heat the normal-temperature flue gas, and the flue gas after the relativehumidity reduces absorbs the heat and is discharged after the temperature rises. According to the environment-friendly and efficient energy-saving direct-fired-type lithium bromide absorption type cold and hot water unit, a chimney can adopt a conventional material and has no special requirements, the flue gas heat can be recycled while white smoke is effectively eliminated, the overall energy efficiency of the unit is improved, and the energy-saving and environment-friendly effects are achieved.
