As the mercury soars, you begin to look for ways to keep cool — literally. Wearing cottons and linen, taking food and drink which cools the body, hiding behind glares and parasols are some of the ways you might commonly try to beat the heat. Another excellent way is to try and lower the temperature of the room or office by installing portable solar coolers as they can be wheeled from one place to another.
Portable evaporative coolers are highly suited for homes located in hot and dry climate as the humidity of the air that has passed through the evaporative cooler is increased in addition to being cooled. As there is no compressor in these units as compared to an air conditioner, the noise level is greatly reduced. As the name suggests the primary source of energy is solar power which is by itself a free resource. If you use solar power instead of electricity, you are making a conscious decision to prevent further global warming. Unlike when you use an air conditioner, you need to let hot air escape from your room if you use an evaporative air cooler. Opening the windows allows fresh air to circulate in the room.
The amount and location of the window openings depend on the wind direction and the size of the room. For example, in mid-size rooms, a 300-mm opening is good enough. Adjusting the louvers or vents will distribute the cool air within a room evenly and widely. The louvers can be turned to the direction where cool air is needed. The most common types of portable solar ac require the use of photovoltaic cells in order to convert sunlight into electricity. These panels need to be installed in an area where the maximum amount of direct sunlight can reach the cells for the longest period of time possible each day. The size of a home will help to determine exactly how many panels are needed, because the amount of electricity that can be generated is directly related to the number of photovoltaic cells that are exposed to the sun.
