A dual stage cascade system uses two refrigeration systems connected in series to achieve temperatures of ~85° Celsius. 0000000796 00000 n
In addition, the critical temperature of refrigerant should be higher and the condensation temperature should be lower. For example, the cascade of a Rankine cycle and an absorption refrigeration cycle has been proposed effectively. ; Balta, M.T. Cui et al. A multistage CRS uses three different refrigerants for natural gas liquefaction in its individual refrigeration cycles: R290, R170 (or R1150) and R50 [. ; Wu, X. Although the refrigerants, basic parameters, and methods in experimental research of CACRS are different, the conclusions are the same. The auto-cascade refrigeration system has also been applied in the cold region in recent years. 0000000016 00000 n

The vapor compression refrigeration cycle is the most common method used for removing heat from a lower temperature level to a higher temperature level using a mechanical work. Total annual cost is the first design objective which includes investment and … ; Choi, W.J. For economic reasons, it is not feasible to transport natural gas in pipelines, thus CRS is used to first liquefy natural gas, which is then transported by marine ships in specially made insulated tanks. An experimental investigation on a modified cascade refrigeration system with an ejector. ; Sekimoto, K.; Nekså, P.
