Portable and Mobile Air Conditioners

It seems there are three main groups of people who want to purchase portable air conditioners. The first group comprises people who have never owned an air conditioner before, cannot stand the sudden onset of heat, and want to purchase a reasonably priced air conditioner that can be used immediately. The second group comprises people who already have stationary air conditioners, but would like to own extra air conditioners that can spot cool places where air conditioning is not sufficient. The third group comprises people who own hotels and other facilities located in areas with relatively cool summer temperatures and do not install air conditioning equipment. They are considering the use of portable air conditioners as a means of addressing the needs of guests who require cooling on rare occasions.
