Beschreibung
Zusammenfassung:	A double-ejector coupling auto-cascade refrigeration cycle system comprises a condenser, a gas-liquid separator, a first ejector, an evaporative condenser, a second ejector and an evaporator, the gas-liquid separator is connected with the condenser through a pipeline, a working medium enters the first ejector through the gas-liquid separator, a first working medium pump and a first generator are sequentially arranged on one path, and a second working medium pump and a second generator are sequentially arranged on the other path. The other path is sequentially provided with a first expansion valve and an evaporative condenser; the working medium enters the second ejector through the gas-liquid separator and has two paths flowing through the evaporative condenser, one path is sequentially provided with a second working medium pump and a second generator, and the other path is sequentially provided with a second expansion valve and an evaporator; outlets of the first ejector and the second ejector are both conne
