Q1 Consider a two-stage compression refrigeration system operating between the pressure limits of 0.8and0.14 MPa(see Fig. Q 2). The working fluid isrefrigerant -134a. The refrigerant leaves thecondenser as a saturated liquid and is throttled to aflash chamberoperating at0.4 MPa. Part ofthe refrigerant evaporates during this flashing process, and this vapour is mixed with the refrigerantleaving the low-pressure compressor. The mixture is then compressed to the condenser pressure bythe high-pressure compressor. The liquid in the flash chamber is throttled to the evaporator pressure,and it cools the refrigerated space as it vaporizes in the evaporator. Assuming the refrigerant leavesthe evaporator as saturated vapor and both compressors are isentropic, determine(a) the fraction of the refrigerant that evaporates as it is throttled to the flash chamber,(b) the amount of heat removed from the refrigerated space and the compressor work per unit massof refrigerant flowing through the…
