A Carnot refrigerator is maintaining foodstuffs in a refrigerator area at 4.44°C by rejecting heat to atmosphere at 27°C. It is desired to maintain some frozen foods at -17.75°C with the same sink temperature of 27°C. What percent increase in work input will be required for the frozen-food unit over the refrigerated unit for the same quantity of heat removed?
