This refrigeration cycle uses R-134a as the working fluid and, for now, assume that it operates on an ideal vapour-compression refrigeration cycle between 0.11 and 1.0 MPa. If the mass flow rate of the refrigerant is 0.075 kg/s, determine
What is the rate of heat removal from the refrigerated space?
What is the power input to the compressor?
What is the rate of heat rejection to the environment?
What is the COP of this ideal process?
Based on this analysis, what is the cost of electricity to operate the cold room for 1 year? Comment on why this differs to the value above
Further data was collected which determined that the working fluid:
enters the compressor at 0.11 MPa and -22°C
leaves the compressor at 1.0 MPa and 60°C
is cooled in the condenser to 0.9 MPa and 20°C
is throttled to 0.12 MPa
Disregarding any heat transfer or pressure losses in the pipes:

1 The refrigeration capacity of the cold room you are considering is 10 kW. It operates for 24 h/d, 360 days of the year. The average temperature outside the cold room is 30°C and the temperature of the air inside the cold room should be 5°C. What is the maximum coefficient of performance for this refrigeration cycle? What is the minimum work required? and If the price of electricity is 0.008 cents per kJ, what is the minimum cost of electricity to run the cold room for 1 year?

The indoor designtemperature is 71ºF. The heat load for the building is known to be 250,000 Btu/hr. Thisheat load accounts for the fact that there are internal heat gains in the building, due tothe presence of people and electronic equipment (e.g., lights and radios). People in thebuilding are usually seated and involved in light activity.a) The furnace had an initial efficiency factor of 73% when installed, but since thenefficiency-improvement retrofits were implemented that raised the efficiency factorto its present value of 82%.
