Ground Rules
The sun brings heat but not cool. The adoption as a source of freshness during the hot weather seems unlikely. However, it is not impossible and in case of misunderstanding or doubt, we must refer to the sensation on contact with light. The latter, after evaporation and will disappear after that, there will be a cold feeling to the place where it was. This principle is also based on the solar cooling system. The latter is acquired after heating with an absorption of a solution of water and a lithium bromide. After heating, the liquid will bring the cold due to a chemical evaporation.
Solar energy used in this system is obtained via solar panels on the roof resting on empty housing. As in the traditional method, after the pre-described chemical reaction, there will be air distribution obtained via a device for this purpose. Note that prior to evaporation, the two components of the reaction dissociate by a mechanism of boiling.
However, it is not only an absorption chiller that can be used to produce fresh via solar energy. There are also machines that use adsorption is still insignificant compared to the first. But experts in the field see it as a better future for this type of equipment. This machine can also be cold water will be carried out either in an air handling unit or in a network of decentralized devices eauapprovisionnant.
Another technique is, it answers the call for cooling or drying by evaporationIn this mechanism, there is in direct contact of water and air cooled. The reaction is obtained increases moisture and subtracts the ambient temperature.
The benefits of solar cooling
The many benefits can be obtained due to the use of solar cooling mode regardless of the method appliedIndeed, it gives the opportunity to benefit from renewable energy without having to spend a lot. In addition, the air is obtained from it is pure and so there is risk of harm to the environment as is the case in conventional systems. With this, there is less increase in gas emission into the atmosphere.
In addition, the device can enjoy mild temperatures during the days when the outside temperature is higherIn addition, the facility has an amortization period longer unlike ordinary facilities. But because of these advantages and its availability is still low in the market, its price is still high. |
