(100 points) Figure below shows the schematic diagram of a two-stage cascade refrigeration system (also called the Economizer 2-Stage Refrigeration Cycle). Comparing to the cascade two-stage refrigeration system discussed in In-class Activity #10a, in this case, the flash chamber (now called Flash Intercooler) is still used but the mixing chamber is removed. The superheated vapor (2) out of the low-pressure compressor (1) is routed into the flash chamber, and the saturated vapor (3) out of the flash chamber enters directly...
