The invention discloses a single-effect type lithium bromide refrigerator for an air separation unit. The single-effect type lithium bromide refrigerator is mainly composed of a generator, a condenser, an evaporator, an absorber, a solution pump, a solvent pump, a vacuum pump, a heat exchanger and a condensate water heat exchanger. A heater communicating with a driving heat source is arranged inside the generator. After an intermediate lithium bromide solution in the generator is heated, vapor can enter the adjacently-communicated condenser. A cooler communicating with a cooling water source is arranged inside the condenser, and the vapor entering the condenser is cooled into a coolant solution. The coolant solution forms a concentrated lithium bromide solution after water evaporation is completed and further enters a connected evaporator collecting tank by means of throttling. The coolant solution in the evaporator collecting tank is pumped up through a connected coolant pump and evenly sprayed onto a connec
