This is when the modern day Air conditioning comes as a God Present. A huge no. of Workplaces, laboratories, hotels, public structures are nowadays fitted with air conditioning systems. Centralized A/c Systems ensure cooling in every nook and corner of the working area.

While this sound hunky dory, its not. Comprehensive cooling is associated to heavy power intake (and waste) causing not just heavy electricity bills however also the dreaded regular power outages. The next action is – obviously – DG sets, to bring the desired convenience indoors, while puffing out clouds of black smoke with awfully high levels of sound contamination for the outdoors world and the environment to sustain.
In the midst of saving ourselves from the fury of the nature, we are accidentally assaulting the nature a growing number of, which keeps returning a lot more furiously every once in a while. One of the most significant points of concern thus is the impending danger due to the rising world temperature levels (Global warming!!). So what shall we do to endure and make it through with convenience?
Let’s not forget we have an immense source of energy in the extremely Sun that we’re shielding ourselves from. One answer is Generation of power using sun’s energy. It’s totally free and in the meantime we can safely presume, unrestricted. Yes, solar power can illuminate our homes and cook our food. But can it also cool our homes? The answer again is yes. Solar air conditioning, an innovative and upcoming technology, offers the response.
Solar air conditioningrefers to any cooling (cooling) system that utilizes solar power. A liquid or a gaseous compound either builds up on the surface area of a solid, permeable substance (adsorption) or is taken up by a liquid or a strong substance (absorption for providing the necessary cooling). In some procedures supply air is straight conditioned, i.e. dealt with in terms of temperature level and humidity
This thermally owned cooling and air-conditioning procedure is at the heart of every solar cooling system. The primary concept of Sorption Assisted Cooling is shown in the graphic here. The solar power is used to dehumidify the sorbent.
This is a 9 phase procedure. In Phase 1 to 2, Sorptive dehumidification of outside air accompanies synchronised increase in temperature level through the released adsorption heat. Then the air is cooled in the heat improvement rotor in the countercurrent to the exhaust air (phase 2 to 3). Air is even more cooled (Phase 3 to 4) through evaporation-humidification; Thus the air inflow to the structure has a lower temperature level and less water vapor than the outside air. In Phase 4 to 5 Heating of the air occurs, and if essential addition of water vapor. Then throughout Phase to 6 structure’s exhaust air temperature is lowered through evaporative cooling in the humidifier. This exhaust air is heated (Phase 6 to 7) in the countercurrent to the air inflow in the heat recovery rotor. The exhaust air is more heated (Phase 7 to 8) through external heat sources (i.e. solar thermal system). Lastly in Stage 8 to 9 Sorption Rotor is Regrowed through the desorption of the bound water.
