    Abstract: This invention relates to a non-heat refrigeration method and a cycle system thereof, the system composes a first stage, one or more median stage(s) and a last stage. The first stage is known refrigerative technique, the other stages condense evapor of self-stage by using cool quantity in lower temperature of preceding stage to effect refrigeration cycle. The first stage provides a cool quantity, the last stage cools a load, the median stage(s) amplify the cool quantity of preceding stage. The temperature of the respective stage rise gradually in connective order, the first stage has lowest temperature and the last stage has highest temperature. This system hasn't heat leaking outside, provides a cool quantity having a lower temperature and ameliorates efficiency.
