for over a thousand years The air conditioner has been around. devices beginning in ancient Rome. the first time scientists make air conditioner to cool down the buildings and Type of air conditioning
the way the builders and scientists made these air conditioners for the buildings was building wind towers and cisterns. The water tank is a large pool of water and when it becomes hot water will evaporate into the air cool and then the tower of the wind will blow air into the building. because the building has a tremendous heat, they must find a way to cool environment
Even in the 1800's nurses and doctors used the same method in the hospital room cooling. This also happened in florida where an American physician to created an ice machine, blowing over the bucket of ice to cool down to make room. air conditioner over time moved  to a more sophisticated model. in the very early 1900's, One of the first modern air conditioning devices was made. AC initially had a substance which is a danger of toxic ammonia. ammonia was replaced with a different better coolant, In the 1920's
Today with the help of electricity  and technology the boom of AC devices have began to take effect. They have made AC units to choose from, from portable, permanent outside air conditioners, commercial air conditioners and residential. at the time of air conditioner is needed in the community, a portable unit is a key thing to have and requires no permanent installation. The difference from portable and Permanent air conditioning is with the permanent installation you don't have that luxury like portable you can move the cool air where ever you go

Can be a fairly difficult task in choosing the best portable air conditioner for your office & home, if you don't know what you're looking for. actually that there are two general types of air conditioners available, one air conditioner has a couple different styles available, it's make difficult in choosing one of them before you start shopping around, you have to understand them, Each style has its pros and cons. generally the cheapest is in portable air conditioning is the evaporating cooler.
           
 Basically air conditioner operates on the principal of pushing hot air through a water-logged medium which will cause reduce the ambient air temperature and evaporation. Although these units require no ventilation, but they incorporate a basin of water that needs to be recharged regularly. This can lead to stuffy if you forget to clean. Ac is very good to use in dry areas, and areas that have high humidity.
            
Cooler that uses evaporation of refrigerant is the second choice. Ventilation is not required in this unit, because they use the exhaust tube to move the hot air outside the areas that need to be cooled. Dual-hose unit using a second exhaust tube, and intake tube, while the unit sprayed using only single-exhaust tube.
           
 One reason to use the intake tube on a dual-spray unit is to develop evenly distribute the air pressure or draw additional air from outside. Pressure difference that allows the hot air from higher pressure areas should be drawn to the area being cooled is probably due to single-hosed units. Air hose is usually best used in small rooms, but if you pick the big room, you can use a dual-hose unit.
