Heat engines transform thermal energy to mechanical energy. A refrigerator is a device that transfers thermal energy from inside the refrigerator to the room outside.
Thermal energy never disappears, but it can be moved from one place to another, which is what a refrigerator does. If you examine your refrigerator you will be able to observe that there are heat exchange tubes (usually on the back) which get hot as they pump heat from the interior to the exterior of the refrigerator.
air conditioner
The coolant absorbs heat inside the fridge, carries it outside, and releases the heat to the air.

Yes, Cooling systems, such as those found in refrigerators, move thermal energy from inside the fridge to outside specifically, CFCs or sometimes Freon Gas is compressed inside a long system of narrow tubes. when the compressed gas passes through a larger area of pipe, it expands and absorbs thermal energy in the process. when it gets back towards the narrow end of the tubing, the thermal energy is almost literally squeezed out of the gas. the large areas of the tubing is on the inside of the fridge, and the narrow tubing on the outside. that's why the back, sides, and bottom of refrigerators are warmer than the surrounding air.
The interior thermal shell is the inside of a cabinet (a refrigerator, or the like) that preserves the coldness and keeps the cold air inside it.
yes because the oven heats the food inside the oven which makes is thermal energy
it is the energy inside thermal heat
