Solar Air Conditioning (SAC) – Guilt-Free Comfort for Summers

Early on summers usually bring a nice relief from the bone chilling winters, but come April & May, the summer heat starts taking its toll, both actually as well as in your mind. And when 2 several weeks. tropical climate, as in most parts of India, the hot days can be all together stress filled. The energy levels of individuals decrease and so does their productivity.

This kind of is when the modern day Air-con comes as a God Gift. A very large no. of Offices, laboratories, hotels, general public buildings are nowadays when you have air health and fitness systems. Centralized Ac Devices ensure cooling atlanta divorce attorneys space and corner of the working space. 

While this all sound hunky dory, its not. Extensive air conditioner is synonymous to heavy electricity consumption (and wastage) leading to not merely heavy electricity bills but also the dreaded frequent power black outs. The next phase is – of course – DG sets, to accept the desired comfort indoors, while puffing out clouds of black smoke with very high levels of reasonable pollution for the exterior world and the surroundings to endure.

In the middle of saving ourselves from the fury of the nature, we are accidentally attacking the nature more and more, which will keep returning even more furiously every now and then. One of the biggest points of matter thus is the upcoming danger due to the rising world temperatures (Global warming!! ). What exactly shall we do to outlive and survive with comfort?

Let’s not forget we have an immense source of energy in the Sun that we’re protecting ourselves from. One answer is Generation of electricity using sun’s energy. Is actually free and for now we can safely suppose, unlimited. Yes, solar energy can illuminate our homes and cook our food. But should it also cool our houses? The answer again is yes. Sun air conditioning, a ground-breaking and upcoming technology, provides the answer.

Solar air conditioningrefers to the air conditioning (cooling) system that uses solar power. A liquid or a gaseous substance either accumulates on the area of a stable, porous substance (adsorption) or is taken on by a liquid or a great material (absorption for providing the necessary cooling). In some processes supply air is directly conditioned, i. electronic. treated in conditions of temperature and humidity

This kind of thermally driven cooling and air-conditioning process is at the heart of every solar cooling system. The primary principle of Sorption Helped Air Conditioning is shown in the graphic here. The solar energy can be used to dehumidify the sorbent.

This is a being unfaithful stage process. In Level 1 to 2, Sorptive dehumidification of outside air takes place with synchronous rise in temperature through the freed adsorption high temperature. Then the air is cooled in the warmth reclamation rotor in the countercurrent to the tire out air (stage 2 to 3). Air is further cooled (Stage 3 to 4) through evaporation-humidification; So the air inflow to the building has a lower temperature and less water vapor than the outside air. In Level 4 to 5 Heat of the air requires place, and if necessary addition of water steam. Then during Stage to six building’s exhaust air temperature is lowered through evaporative cooling in the humidifier. This exhaust air is heated (Stage 6th to 7) in the countercurrent to the air inflow in hot weather reclamation rotor. The wear out air is further heated up (Stage 7 to 8) through external heat options (i. e. solar heat system). Finally in Level 8 to 9 Sorption Rotor is Regenerated through the desorption of the bound water.

Open and Closed cycle Air Health and fitness Systems:

Open-cycle systems are more beneficial in structures with high humidity tons and high air exchange rates. The installation of ducts for the source air and the returning air, and a heat restoration unit is essential. In this, the outside air is dehumidified through sorption which is then brought to the desired temperature by high temperature recovery as well as direct and indirect evaporative cooling. Usually dehumidifying is achieved in a disc containing the desiccant materials silica gel or li chloride, but increasingly fresh desiccants (desiccant material: li chloride) are being attempted. In these systems the solar heat is required for the regeneration of the absorption/adsorption unit.

Closed-cycle desiccant evaporative cooling systems are based on the processes of Adsorption (based on solid desiccants like silica gel or Zeolites with water as refrigerant) or Absorption (where desiccants are liquid ex. materials pairs of lithium bromide as desiccant and drinking water as refrigerant, or normal water as desiccant and hydrogen as refrigerant, where subwoofer Zero temperatures may be required).

For cooling and acclimatizing of buildings, only solar-thermally driven processes are used.

In actual practice, solar collectors are being used to convert solar radiation to heat that can now be provided into a thermally influenced cooling process or into a direct air-conditioning process. Particularly in special applications, for example for chilling medicines in remote areas that are not linked to the grid, a photovoltaic generator transforms photo voltaic radiation to solar electricity that then drives a refrigeration process – usually in the form of a compression chiller.

Presently there have been considerable innovations in the field of solar-assisted heating and air conditioning and world over this technology has been rapidly tried out and adopted.
