Repeating someone else's error does not make it right...
At least the photo is showing it's correct usage. It will produce a stream of cooler air if used outside and heat generated will dissipate to atmosphere. If you use it inside it will increase the temperature of the room overall and increase the humidity. Increasing humidity will actually reduce evaporative heat loss from any humans in the room. It is most definitely not an air conditioner usable indoors. All airconditioners generate heat which is why the units are usually outside the rooms they are cooling.
Good one, thanks for sharing :)
Thats groupon for you. Half the deals arn't what they seem.
