Because energy can't be taken away (except with fusion of atoms larger then iron, which is impractical for a refrigerator). This means the energy, the heat, has to be moved to another place for one place become lower in temperature.
A refrigerator is an example of a heat mover.
Normally, heat moves from a higher temperature to a lower temperature. Devices that use work to move heat are called heat movers. A refrigerator is an example of a heat mover because it takes the heat from inside of the refrigerator and moves it to the outside. The 2nd law of thermodynamics allows this to occur if work is done in the process. A refrigerator does work as it moves the heat from inside the refrigerator to the warmer room.
A heat engine converts heat into mechanical energy, typically by using the heat to produce steam and drive a turbine. A heat mover, on the other hand, transfers heat from one place to another, such as in a refrigerator or air conditioner, by using a refrigerant to absorb and release heat through a thermodynamic cycle.
A heat mover is a device or system that transfers heat from one location to another. This can involve removing heat from a space to cool it down (such as in air conditioning systems) or transferring heat to a space to warm it up (such as in heat pumps).
No, a refrigerator does not change heat into cold. It removes heat from inside the refrigerator and releases it outside, resulting in the cooling effect inside the refrigerator.

A good example of this process is a refrigerator. Electricity is used to power the refrigerator to keep it cool. The room that the fridge is in is warmer. Normally the warm air from the room should flow into the refrigerator until they are the same temperature. The heat mover, which is the refrigerator in this case, absorbs the heat the cooler air absorbs, and moves it back into the room. This keeps the fridge at a constant temperature.

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.
A device that heats a home by removing thermal energy from one location and transferring it to another location is a heat mover. An example of a heat mover is a refrigerator.
