The refrigerant
air conditioner
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 lag
Cavity wall insulation is the addition of an insulating material between two layers of wall on the outside of a building. It reduces energy transfer by preventing heat (from the inside or the outside) from travelling through the wall to surrounding air.
Probably not. If a refrigerator were in a room so cold that the outside temperature caused the refrigerator to be very cold inside, the thermostat in the refrigerator might not ever cause the device to actually use any energy. For most normal purposes, the refrigerator will be better off in a cooler room simply because the outside atmosphere will not be constantly warming up the fridge from the outside. Think about how much more you need the air conditioning on to keep a room at 70 degrees on a hot day than on a cold one.
air conditioner
A device that transfers thermal energy from a cool region to a warm region is called a Heat Pump. Refrigerators are an example of this. So are many air conditioning units.
It removes thermal energy on what ever you place on the refrigerator. The first principle is transfer of heat, the second is solidification or vapourization.

thermal lag
By slowing the transfer of energy from inside to outside.
Cavity wall insulation is the addition of an insulating material between two layers of wall on the outside of a building. It reduces energy transfer by preventing heat (from the inside or the outside) from travelling through the wall to surrounding air.
The transfer of energy is called Energy Transfer

No. A refrigerator magnet does not have a strong enough magnet field to affect your motor. Also the motor is mounted either at the top of bottom of your fridge. Far enough away from the outside of the door.
