Fridge power/heat

  1. Jun 23, 2014 #1
    I've got a few things I want to make sure I have right about refrigerators. When the fridge operates, it removes heat from inside, and moves it to the outside. The outside of the fridge is warm. This is one source of heat from the fridge. Unfortunately, this process is not 100% efficient, so some energy is dissipated as heat. I believe that this is all of the energy, so if a fridge is using 300 watts, it dissipates 300 watts of heat, and is like a 300 watt heater. This only includes the heat output from inefficiencies, and not the heat that is removed from the inside. Is this correct?

    Thank you!

    Ultimately, all of the electrical energy used by the fridge becomes heat in the room.
