A separated type solar energy absorption type refrigerating system comprises an energy station and a plurality of tail end devices, wherein the energy station consists of a generator (1), a condenser (2), a dilute solution tank (5), a concentrated solution tank (6), a solar energy heat pipe type evacuated tube collector (9), a concentrated natural cold source (10) and a condensed water tank (29) as well as a system pipeline, each tail end device consists of an absorber (3), a evaporator (4) and a solution dehumidification unit (23) as well as the system pipeline; and the refrigerating system is characterized in that the generator or condenser and absorber or evaporator of an absorption type unit are separated into the energy station and the plurality of tail end devices, and capillary tubes are taken as the heat exchanger material of the condenser (2), the absorber (3) and the evaporator (4). The refrigerating system combines the absorption type refrigeration and the solution dehumidification into a whole, comprehensively utilizes the renewable energy sources such as solar energy, low grade natural cold source and the like, improves the utilization ratio of system energy, realizes energy cascade use and meets the requirements of energy conservation and emission reduction.
