Ansessument Notes : - No talking during assesrmest and aftempt all parts. - All questions carry equal marks. - Indicare Namie 4 studebt Nunber on all subenited work. Question No I. The owner of hotel with the electrical and themsal load profiles is proposing to install a CHP with a capacity of 300 kWe. Using data below: Calculate: (i) The cost of energy with and without the CHP engine, (ii) The simple payback period. Dana: CHP output ratios, 25% lost, 30% electrical \& 45% thermal; CHP runtime, 5,280 hrslyr; CHP capial cost. E 65,000; CHP maintenance cost as a function of power generated, 42 e/k Wh; boiler efficiency. 80%; cost of electricity, 11ck Wh; cost of gas, 2.5ckkWh. Fing 01 Question Ne 2 For the Lithium Bromide Absorption Chiller PID shown in Fig. Q2, Calculate; (i) The mass flow rate of the liquid between the Condenser and Evaporator: (ii) The energy inputs to Generator and Absorber. (iii) The energy outputs from Condenser and Evaporator. (iv) The COP of the Chiller.
