Question

The given answer is (d) (i) 15.18 kW (ii) 3.08

However, I don't know how can I solve this question.

Could anyone please help me?

Thank you

d) A freezer maintains a temperature of -18°C inside the cabinet, while the room temperature is at 24°C. If the electrical power consumed by the refrigeration unit is 2.5 kW determine: (i) The maximum possible rate of heat removal from the cabinet at this power input. (ii) The COP of the refrigeration unit if the actual rate of heat transfer to the outside (room) air is 10.2 kW. (4 marks)

    During winter time a heat pump is operating on a heating mode to maintain a living room at 23oC during which the outside temperature is -5oC. The system is using R134a as a working fluid. The refrigerant leaves the condenser at 28oC and enters a compressor at -10oC. The refrigerant flow rate is 0.12kg/s. Assume an ideal VCC to evaluate the system and report the followings: a. Process diagram b. Heating capacity kJ/hr c. Coefficient of performance of the system...
