Chiller vs Freezer vs Refrigerator vs Heat Pump
All these machines that are named as Chiller, Freezer, Refrigerator and Heat Pump work on the same principle to transfer the heat from objects or source to surrounding or sink. This major principle is refrigeration and evaporation is adopted to achieve the task. The difference between these machines is only that, they work on different capacities and for different objects. Chillers are used to lower temperature of liquids within the range 35-45 degree Fahrenheit. However, freezers can reduce temperature of objects within the range -10 to – 30 degree Fahrenheit in contrast to refrigerators that is again used for cooling the objects but up to temperature range – 10 degree Fahrenheit. Heat pumps are different from all these machines just in one respect that they can be used either to lower or even to increase temperature.
