A household refrigerator operates on an ideal vapour compression refrigeration cycle
with R-410A as the working fluid. The cycle has a minimum pressure of 300 kPa and a maximum pressure of 2
MPa. The mass flow rate of the R-410A Is 0.06 kR/s.
(a)
(b)
(c)
(d)
Show the cycle on a T-s diagram with the 4 stages of the cycte clearly identified.
What is the coefficient of performance for the cycle?
What is the rate of heat rejection from the condenser in kW?
Could this unit operate in a house where the temperature reaches 28°C? Explain your answer.
