2. a) A heat pump designed to deliver heat at 55C absorbs heat from low temperature environment at 5*C. CoP of the heat pump is 5. Calculate CoP of an equivalent Carnot heat pump and discuss how the performance can be improved. [4 Marks] b) A cooling system using R134a operates between 2 bar and 9 bar. Compressor efficiency is 85%. Calculate the mass flow rate of required to achieve 300kW of cooling. [14 Marks] c) Minimum SEER required nowadays is 15. Calculate CoP and SEER of the cooling system in part b and discuss. What is the minimum CoP required to achieve SEER of 15? Assume EER = 0.875*SEER (for residential cooling) and EER = 3.4121*COP [7 Marks]
