How Does a Fridge Make Things Cold?

How can a refrigerator keep your soda cold while its machinery warms the kitchen? Follow the heat with Professor X and discover the hidden cycle inside an everyday fridge. We take apart the evaporator, compressor, condenser, and expansion device to see how refrigerant changes pressure and state. Then we follow the air through the freezer and fresh-food compartment, explore temperature controls and door seals, and find out why a cold machine sometimes needs a heater. Along the way, you'll discover where the heat from your food goes, why the center of a drink takes time to cool, and why leaving the fridge door open won't cool your room.
