A heat pump uses refrigerant-134s as a working fluid to heat a home. It operates on an ideal vapour-compression cycle. The low pressure is 2bars and the compression ratio of the pump is 5. Address the following: i) Plot the P-h diagram of the cycle on the R134s diagram provided. (10 marks) ii) Specify the four processes involved in the cycle and write the 1st law of thermodynamics for open systems for each one of the components involved. (10 marks) iii) Calculate the pump specific work and the specific heat absorbed from the environment. (10 marks) iv) If heat is absorbed at a rate of 5kW from the environment, calculate the heating power delivered to the house.
