摘要
根据某冷库项目的实际应用情况,为其设计跨临界CO2 增压气体旁通制冷系统,计算该系统的热力循环过程、各状态点参数值、制冷剂循环量、系统制冷量,对主要设备进行选型分析,并阐述计算及选型过程中需要注意的细节,供相关冷库设计人员参考.
Abstract
According to the practical application of one cold storage project,the tran-scritical CO2 refrigeration system with increase pressure gas bypass is designed.The calcu-lation is conducted on the thermodynamic cycle process of system,the parameter values of each state point,the refrigerant circulation volume,and the system cooling capacity.The type selection of the main equipment is analyzed.In addition,some details that need atten-tion in the calculation and selection process are described,which can provide references for related designers of cold storage.
