SUMMARY
The introduction of a refrigerator into a thermally isolated room at 70 degrees Fahrenheit will result in a net increase in room temperature. This occurs because the refrigerator, while cooling its interior to approximately 50 degrees Fahrenheit, expels heat into the room due to the inefficiencies of its motor and refrigeration process. The energy consumed by the refrigerator to operate contributes additional thermal energy to the room, leading to a warmer environment overall. Experiments, such as using a window air conditioner in a closed room, further illustrate this principle.
