| Abstract: | A novel refrigeration system employing ammonia as refrigerant was put forward which can be used to obtain as low temperature as-60℃,and it is a new environment friendly technical offer of cold store constructing.There are two evaporating temperature circuits in this new refrigeration system.The evaporating temperature in high temperature circuit can be adjusted from-35℃ to-25℃ and that in low temperature circuit can be regulated within the range of-50℃ to-65℃.The two circuits meet at low pressure circulating vessel.The characteristics of the system and problems should be solved when being applied were analyzed on the basis of thermodynamic calculation.This refrigeration system can be used in the building or rebuilding of cold store with-50~-60℃ room temperature. |
