Feel the pride of being the part of such a glorious nation. Here's sending my warm patriotic wishes to make this day truly memorable. On this Independence Day, take a minute or two to thank for such a precious gift. Take time to cherish your life and your motherland. Not forgetting the sacrifice made by our heroes who have made this day a reality. Happy Independence Day 2018.

Solar Cooling System

Solar Cooling System: It is really odd to use something extremely hot as the sun is, to cool a place. Fortunately, it happens, and it also reduces electricity costs in a remarkable way.

    • Passive cooling
        • It is achieved in two steps:

            • Prevent heat transfer

          Shading, proper window positioning and are significantly effective.

Proper Roof Design

        • Remove heat from the building

      For hot humid climates TACS are mostly used, whereas cooling towers & solar chimneys and ventilation techniques are prefered in mild climates.


  • Active Cooling – Thermally Activated Cooling systems
      • (TACS)

    These systems use the sun to provide 30% to 60% of a building’s cooling requirements. Usually, they are supported by an alternative fuel source such as natural gas.


    • TACS is divided into two categories:

      • Absorption coolers
      • Desiccant coolers


  • Generally, TACS are not prefered because they are too expensive to install and they need large solar fields to collect sun’s energy.

Solar VentilationPassive solar ventilation concept is very simple. It just works as a greenhouse does. It uses the ability of hot air to go up, to insert or remove air from the building.

Using a solar chimney, a solar wall or a solar room we create air updraft to produce ventilation.

In winter, hot air is driven into the house to heat it.
In the summer, ventilation can be used to cool a room.

P.S. Solar thermal power is one of the most effective forms of solar energy because we can use it as it is. Why should we invest in passive solar heating, cooling and ventilation? Because using sun’s renewable energy, they offset zero carbon dioxide helping to save the environment. Solar heating, cooling and ventilation are the most used technologies for residential solar energy use.
