Carnot refrigerator and II law of Thermodynamics

[sodaboy7]

As per II law of thermodynamics you it is NOT possible that a hotter body becomes hotter and colder body becomes colder when in contact. But in a Carnot refrigerator, the heat is taken from a cold reservoir and pushed to a hotter one. It sort of opposite the II law. Help me over this paradoxical situation.

There is an input of work in the carnot refrigerator.

The second law of thermodynamics states that heat does not flow from a cold reservoir to a hot reservoir spontaneously. However, heat may flow from a cold reservoir to a hot reservoir with the input of work.

From the outside it might look like heat moves against a thermal gradient, but if you look at the processes, you'll see it never does.
