An ideal reversed heat engine is used to maintain a low-temperature storage vault at a steady temperature of −23 ∘C-23\text{ }^{\circ}\text{C}−23 ∘C by discharging heat into a surrounding workspace maintained at a temperature of 27 ∘C27\text{ }^{\circ}\text{C}27 ∘C.
Calculate the minimum electrical power input required to run the engine if it rejects heat to the workspace at a rate of 1.35 kW.
