Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -30°C by rejecting its waste heat to cooling water that enters the condenser at 18°C at a rate of 0.29 kg/s and leaves at 26°C. The refrigerant enters the condenser at 1.2 MPa and 65°C and leaves at 42°C. The inlet state of the compressor is 60 kPa and -34°C and the compressor is estimated to gain a net heat of 430 W from the surroundings. The heat exchanger loses no heat to the environment. 26°C 42°C ↓ Condenser 3 Expansion valve Water 18°C Evaporator QL (2) 1.2 MPa 65°C lin Win Compressor 60 kPa -34°C Determine the COP of the refrigerator.

An ammonia-water absorption refrigeration cycle is used to keep a space at -5 C when the ambient temperature is 20 C. Pure ammonia enters the condenser at 20 bar and 60 C at a rate of 0.02 kg/s. Ammonia leaves the condenser as a saturated liquid and is expanded to 2 bar. Ammonia leaves the evaporator as a saturated vapor. Heat is supplied to the generator by geothermal liquid water that enters at 100 C at a rate of 0.25 kg/s and leaves at 70 C. Determine (a) the cooling capacity (in TR) and (b) COP of the system. The enthalpies of ammonia at various states of the system are: condenser inlet h2 = 1510 kJ/kg, evaporator inlet h4 = 418 kJ/kg, evaporator exit h1 = 1420 kJ/kg. Take the specific heat of geothermal water to be 4.18 kJ/kg-K
MODULE: THERMODYNAMIC QUESTION 5 Consider a two-stage cascade refrigeration cycle with a flash chamber as shown in the figure with refrigerant-134a as the working fluid. The evaporator temperature is −10.09°C and the condenser pressure is 1600 kPa. The refrigerant leaves the condenser as a saturated liquid and is throttled to a flash chamber operating at 0.4 MPa. Part of the refrigerant evaporates during this flashing process, and this vapour is mixed with the refrigerant leaving the low-pressure compressor. The mixture is then compressed to the condenser pressure by the high-pressure compressor. The liquid in the flash chamber is throttled to the evaporator pressure and cools the refrigerated space as it vaporizes in the evaporator. Assuming the refrigerant leaves the evaporator as a saturated vapour determine the COP of this refrigerator. NOTE: Your answer should be in 2 decimal places.
