Abstract
This paper mainly introduces a new type of secondary refrigerant ZC-7 used in the secondary refrigeration system,through the comparative analysis of different secondary refrigerants,its thermodynamic properties are better,it is more suitable for cryogenic refrigeration systems;A new type of heat exchanger tailored to the secondary refrigeration system was introduced——the box type heat exchanger,compared with conventional heat exchangers,its heat transfer efficiency is higher and it has the ability to store cold,adjustable use of electricity;The secondary refrigeration system composed of the new type of secondary refrigerant ZC-7+the box type heat exchanger cools down quickly,efficient and energy conservation,the daily operating costs of the cold storage are greatly reduced,it has positive significance for the development of refrigeration system.关键词
