With the high rates of temperature during the summer, and the dry weather that characterizes many Arab countries, air conditioners have become indispensable devices in homes, gatherings, restaurants, and even commercial centers. Therefore, air conditioners, especially desert air conditioners, are important parts of every home.
The desert air conditioner is one of the most important and most widely used forms of electrical air conditioners in dry areas, such as desert areas, which face a high temperature during the summer.
The desert air conditioner is a type of air-cooling machine, and works to cool the air heat through the evaporation of water. When the water turns from a liquid state to a gaseous state, it absorbs heat from the surrounding atmosphere, which becomes colder, and this heat is called the latent heat of evaporation.
The desert air conditioners consist of a pump that pumps water into the water fillings intended for cooling, and a fan equipped with a motor that sucks the hot outside air and passes it over these fillings, where the water is evaporated by the latent heat in this air, which causes a decrease in the air temperature and cooling, then re-pumping and distributing This cool air is blown into the building by the fan.
The desert air conditioner consists of a water tank coated with a rust-resistant material, a valve that determines the water level, a pump to circulate the water, a fan, gaskets or water-wetting cushions, and a water distribution system consisting of copper tubes.
The cooling process starts from the air conditioner basin, where it is filled with water through pipes designated for that until it reaches a certain level, after which the water is raised through the pump to the upper part of the air conditioner that contains the distribution system to ensure that the water is distributed in an equal amount on the water fillings intended for humidification, then the compressor pulls the air Through water fillings, it is cooled in the air conditioner to be released to the outside air, cool and moist, through the fan, which ensures a balanced distribution of air throughout the room.
Desert air conditioners are distinguished by increasing the humidity in addition to reducing the temperature, to create a natural mixture for humans of humidity and temperature, where the air is drawn in and cooled to the required temperature and then re-introduced into the room, thus withdrawing the room’s heat and adding moisture to it by passing the air with a water mist that draws the hea#.
Types of desert air conditioners
In terms of the principle of operation, there is no significant difference between the types of desert water conditioners, but they differ in the method of installation and the type of air conditioner filling.
The portable desert air conditioner is one of the most important types due to its ability to move and move, and it is characterized by a water tank integrated with the air conditioner that can be moved with a complete movement system according to the length of the power cord, and this type of air conditioner is often used in gardens, entrances and shops.
As for the window desert air conditioner, it works with the same mechanism, but it is installed in the wall and most of the body of the air conditioner is outside the room. All you see inside the room is the air outlet that is level with the wall, and the outer part is supported by metal bases to carry the body of the air conditioner. This type of air conditioner, although One of its special installation requirements and the need to make a large hole in the wall; But it's more efficient than a portable water conditioner, because it has more empty space around the air intake.
As for the cooling pads, there are two main types of padding for the desert air conditioner. The first type of cardboard is known as the beehive, and it is made of natural materials that do not cause allergies and have the ability to partially absorb water. The second type is straw, which is made of yarns similar to hemp and straw. And the more the air conditioner is designed to accommodate the thicker cardboard panels, the better.
It is preferable to replace the cooling pads annually and clean the air conditioner and the tank in order to increase the quality, obtain a higher cooling rate, and extend the life of the desert air conditioner.
The desert air conditioner is environmentally friendly, as it does not produce any emissions unlike other conventional cooling systems, and the desert air conditioner does not contain refrigerant gas or a compressor. Moreover, it does not release any toxic chemicals into the air, and its mechanism of action, which is to cool the air with water, does not use any refrigerants that may harm the environment, unlike most chemicals used in refrigerator air conditioning systems that deplete the ozone layer and contribute to global warming.
One of the advantages of the desert air conditioner is that the cooler is equipped with a filter to help filter odor-causing pollutants and dirt from the indoor atmosphere, which leads to a significant improvement in the indoor air quality in your room.
Finally, several points must be taken into account when purchasing a desert air conditioner that differs according to the need for it, such as the environment in which the desert air conditioner will operate, size, portability and mobility, and the proportionality of the size of the air conditioner with the place in which it will be installed.
