Difference Between A/C and Refrigerator

In a refrigerating system we produce cooling where as in every air-conditioning system we will need the use of this refrigeration system to cool the air.it is,therefore,stated that air-conditioning system is only a sub-system of refrigeration system.
Conditioning air by controlling humidity, purity, flow, temperature in a closed air or semi closed area is air conditioning. And extracting heat from an area and rejecting it to sink or surrounding for keeping desired area at a low temperature than surrounding is refrigeration.
both have same type of compressor ,but the only difference is cooling capacity is different .for refrigerator it is not necessary to cool immediately while for A/C it requires fast cooling power.
