摘要(Abstract):

针对R290/CO2复叠式制冷循环系统中R290与CO2的冷凝蒸发换热特点,设计了R290/CO2冷凝蒸发器,对R290/CO2冷凝蒸发器进行了安全性分析,制造出的U型换热管式R290/CO2冷凝蒸发器,为自然工质R290/CO2复叠式制冷循环系统走向实际应用打下了基础。
The R290/CO2 condenser-evaporator is designed taking into account the heat exchange characteristic of CO2 condensation and R290 evaporation in R290/CO2 cascaded refrigeration cycle.The security of the R290/CO2 condenser-evaporator is analyzed.The manufacturing of new U-type tube R290/CO2 condenser-evaporator provides base for application of natural refrigerants R290/CO2 cascaded refrigeration cycle system.
