The invention relates to an organic Rankine cycle generating set easy to reclaim an organic working medium. The organic Rankine cycle generating set comprises an organic Rankine cycle device, which consists of an evaporator, a gas-liquid separator, an organic turbo-expander, a heat regenerator, a condenser, a liquid accumulator and a working medium pump. The organic Rankine cycle generating set further comprises a compression condensing unit with a throttling device and a cooling system consisting of evaporator coils, wherein the evaporator coils are uniformly distributed and circled outside the liquid accumulator or uniformly mounted inside the liquid accumulator. As the additionally arranged cooling system is used for cooling down the liquid accumulator, the corresponding saturation pressure of the organic working medium at the liquid accumulator is lower while the pressure at other parts of the generating set is higher, and then residual organic working medium in pipelines and other parts of the generating set can be transferred to the liquid accumulator. After the generating set works for a period of time, most organic working medium in the generating set and the pipelines can be recovered in the liquid accumulator, so that the problem that the organic working medium is condensed to be liquid and exists in pipelines and parts of the device after a traditional ORC (Organic Rankine Cycle) device stops or during maintenance and repair.
