Why my unit is not an Air Conditioner?

An evaporative Outdoor Air Cooler is not an air  conditioner as it does not use a compressor and refrigerant gas. One  should not expect an evaporative air cooler to work as effectively as  refrigerated air conditioning. However,the advantages of the evaporative  air cooler over refrigerated air conditioning are: Low purchase cost, Low electricity usage, Environment friendly (No refrigerant gas) and Maximum portability.
