Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Where, T1 = Low-temperature reservoir, T2 = High-temperature reservoir, Q1 = Heat supplied to refrigerator, Q2 = Heat rejected by refrigerator, WR = Work input given to refrigerator
Heat rejected to the higher temperature in Carnot refrigeration = Refrigeration effect + Work input
Q2 = Q1 + WR
Calculation:
Given:
TL= - 30°C , Winput = 1.28 kW , QS = 1 TR = 3.5167 kW
QR = QS + Winput = 3.51 + 1.28 = 4.79 kW
