The invention discloses an intermediate cooling two-stage absorption refrigeration system, comprising a high-pressure generator, a condenser, a first throttling device, an intercooler, a high-pressure absorber, a first circulation pump, a second throttling device, The first solution heat exchanger, the third throttling device, evaporator, low-pressure absorber, second circulating pump, fourth throttling device, second solution heat exchanger and low-pressure generator, compared with the traditional two-stage absorption Refrigeration system, the present invention adds an intercooler and changes the connecting pipeline, promotes reasonable energy coupling inside the intercooler through reasonable distribution of steam at the outlet of the low-pressure generator, realizes the change of the intermediate temperature, and effectively adjusts the temperature and generation of high and low pressure stages. The heat input of the device and the corresponding refrigerant flow distribution enable the low-pressure stage to use extremely low-grade heat sources, thereby increasing the utilization range of waste heat absorbed by the two stages, making it more applicable and more flexible to adjust; in addition, through reasonable intermediate temperature adjustment , The cycle performance coefficient can reach more than 0.4.
