Although passive evaporative cooling has been a feature for desert architecture for centuries now, Western acceptance, study, innovation and commercial use are all relatively recent. The best portable cooler depends on your location, your needs and your budget. The most efficient AC units are portable. They reduce the temperature to what you consider comfortable. However, they can also be dangerous in the event of a leak. Although electric fans are not the most efficient at cooling your personal space they can be very effective. However, you can still find good-quality models at a reasonable price. Some models of evaporative cooling units can be used in combination with humidifiers for a drier winter season. Evaporative coolers cost about one-half as much to install as central air conditioners and use about one-quarter as much energy.
Evaporative coolers add moisture in the air. It works by using the process of evaporate to cool your house, office, or immediate environment. This makes them ideal for people with dry eyes or skin.
Humidity will build up if the windows don't open enough. To get the best results, all air conditioners -- portable AC, central, or split -- must be operated in a closed environment. You need to keep windows closed to hold in the cold air and to keep the humidity level from rising after your machine has worked so hard to pump out all the heat. A portable air conditioner will actually need an exhaust pipe through a window in order to remove the heat from the air.
The metal surface of the baseplate is part of the waterblock, which is designed to be filled with coolant. Air coolers can raise the humidity level in your house which can lead to mold growth problems. Mold and mold thrive at a relative humidity of 60% or higher. The decision of whether you should buy a swamp cooler or a more advanced air conditioner is a personal decision that will vary from person to person.
Mixed system coolers provide maximum efficiency. They incorporate both indirect and direct cooling methods and cool the air in two stages. As a result, the incoming stale airflow has lower dry-bulb as well as wet-bulb temperature. Direct evaporative coolers work by cooling the air.
