There is a cooling cycle as shown in the figure. The processes are known to be: - Process of 1 2; Isoentropic - Process of 2 3 ; Isobrico - Process of 3 4 ; Isoentalpic - Process of 4 1; Isobaric The heat extracted in the evaporator is 10 TON. NOTE: - The working substance is R 134a for - The working substance is R 22 for students whose number is between students whose number is between N- 1 and 50. the N- 51 to the end. -1 TON = 3.52 kW - Use the EES Program to obtain the properties of each refrigerant QA Ta -40C, ww .3 condeser = constant hade * R-134a R- 22 p-ce la sa w = IOTON Ti=-20C X = 1.0 Calculate: a) The flow of refrigerant, in kg/s. h (kJ/kg) No 1 3 4 b) The power required by el compressor, in kW. c) The heat rejected in the condenser to the outside medium, in kW. d) The COP of the cyclo.
