Why is two-stage compression popular for extra-low-temperature refrigeration systems?
Condensers in these refrigerators are all_______cooled.
please answers fasterrr An ice-making machine in Restoran Syed operates on the vapor-compression refrigeration cycle. Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.13MPa and a °C at a rate of 0.13kg/s, and it leaves at 0.7 MPa and b °C. The refrigerantis cooled in the condenser to c°C and dMPa, and it is throttled to 0.14MPa. Disregarding any heat transfer and pressure drops in the connecting lines between the components, show the cycle on a T-s diagram with respect to saturation lines, and determine;i.the rate of heat removal from the refrigerated space,ii.the power input to the compressor, iii.the isentropic efficiency of the compressor, and iv.the COP of the refrigerator.v.if the compressor has no irreversibility, how about the COP?vi.Justify the difference between ideal and actual cycles. a= -8 b= 49 c= 25 d= 670
