  Both are heat pumps. They move heat from a cold zone to a hotter one. The refrigerants used are suited to the temperatures involved.

  Just like a water pump moves water from a lower level to a higher, a heat pump moves heat from a lower temperature to a higher temperature, which is what happens in a refrigerator. However, in this case the interest is in the cold space inside and the need to keep it that way. In other cases such as heating a cold space in very cold places like the Arctic zone a heat pump is used to remove heat from the out side cold area and deliver it into the warmer room to continue keeping it warm. One must understand that a heat pump does not generate heat but only moves it. So, for a given power much more heat can be moved than created by a heater.
  For comparison a 1 ton ac moves about 3300 KCals/hour for a power expenditure of about 1.3 KW against nearly 4KW for a heater to generate the same heat.
