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. (10 marks)

(1) b) The diagram contains how many control loops? (1) c) Are the control loops open or closed? (1) d) The controlled variables are and (2) e) The tag for TIC100 tells us that the device is used for and is part of loop (3) f) The symbol for TT100 tells us that the device is located (1) g) The line connecting FT101 and FIC101 indicates what signal type? (1) h) The line connecting TIC100 and TV100 indicates what signal type? (1) i) The measured variables include and (2) j) Identify the final control element in each loop by its tag. and (2) k) Assuming that TIC100 and FIC101 output electrical signals, draw the P&ID representation below for the device that would be required to interface the output with the FCE. Note that you will need to draw two symbols - one for each control loop. (3)
