Assume that the Carnot refrigerating machine in Example 8.2 is of unknown capacity. Considering both parts

(a) and (b), what would be the increase in the percentage of work input required for the freezer box over the refrigerated space for the same extent of refrigerating effect?

Example 8.2

(a) A one-ton Carnot refrigerating machine is used to keep a refrigerated space at the temperature of \(-10^{\circ} \mathrm{C}\), while the environment is at \(45^{\circ} \mathrm{C}\). Determine the power consumption of the machine.

(b) If the machine is used to maintain a freezer box at the temperature of \(-20^{\circ} \mathrm{C}\) while the temperature of environment is \(45^{\circ} \mathrm{C}\), then how much cooling effect could it produce?

Assume that the power consumption in both the cases are same.
