If you've ever wondered how a refrigerator works, the mechanics inside can vary, but the principals are the same. Refrigerators simply remove heat from the items placed inside - it moves heat from inside the compartment to the outside. The resulting effect is that anything inside the fridge gets cold.

Thermodynamic laws dictate that temperature in any environment tends to normalize amongst each object in that environment. In keeping with this, we can better understand - a warm object placed inside a refrigerator among cold objects will eventually equalize in temperature.

Another good example of a heat pump is the air conditioner.

Just like a refrigerator, an air conditioner gets quite warm outside the room, while it pumps cool air inside the room. Window mounted room units give off a warm breeze of air outside as do separate AC condenser units used in central AC installations.
