Absorption-compression composite refrigeration cycle system

The invention relates to an absorption-compression composite refrigeration cycle system. The system realizes double-energy driving (composite driving of power and heat), double-temperature cold output and double-station running. The system consists of a flat plate type solar heat collector, a generator or rectification tower, a condenser, a refrigerant heat exchanger, a diverter valve, a first throttling valve, a second throttling valve, a first evaporator, a second evaporator, a first compressor, a mixer, a second compressor, a cut-off valve, an absorber, a solution pump, a solution pressure reducing valve, a solution heat exchanger and a water pump which are connected according to a certain rule. The system can drive in two forms, namely low-grade heat of solar energy, after heat and the like and mechanical power (electricity), simultaneously output cold of two or more temperatures, realize absorption-compression composite cycle refrigeration, can independently run under two working conditions of the compre
