A refrigeration system uses 134a refrigerant and is operating at a condenser pressure of 1000kPa. The refrigerant is subcooled by 20deg C in the condenser. If the temperatures of the refrigerant entering and leaving the evaporator are -30deg C and 10deg C respectively, and the flow rate of the refrigerant is 0.15k(g)/(s), determine the following quantities if the efficiency of the compressor is 75%.
a. The degree of superheat in the evaporator
b. The temperature of the refrigerant at the exit of the compressor
c. The work done on the refrigerant by the compressor
d. Rating of the compressor
e. The rate of heat exchanged in the condenser
f. The rate of heat exchanged in the evaporator
g. The C.O.P. of the system
