How Does Solar Air Conditioning Work?

 In Articles

Solar air conditioning is powered by solar panels that take energy from the sun’s light.

Why is solar air conditioning useful?

There are many benefits to solar air conditioning. For example, when the power goes out due to storms or heat waves, harvesting the sun’s light in solar cells can provide electricity-less energy to power your air conditioner and keep your home cooled.

Death from a heat wave is more common than you think. In 2003 alone, over 35,000 people died from a heat wave in Europe. Not only will solar air conditioning have optimal effects during long summer hours of blistering heat, but it will also help reduce the use of fossil fuels.

Using renewable resources will contribute to having a green footprint in the world. This is because on average, there are an estimated 140 million tons of CO2, also known as a greenhouse gas, which comes from normal air conditioners. Since the days are getting hotter, these greenhouse gas emissions have increased by a quarter in the last 2 centuries.

Using solar-powered air conditioning systems just makes sense in light of this data.

How does solar air conditioning work?

The process of operation of solar air conditioning is called sorption. This is known as a thermo-chemical process. There is a sorbent, usually something like silica gel, which is heated by the solar panel and then condensed. When the sorbent has been successfully dried up, sorption is then repeated to continue the energy flow.

What are the types of solar cooling?

There are two types of solar air conditioning. These two are closed systems and open systems. The difference between the two is that closed systems usually use chilled water to cool where as open systems use recycled, dehumidified air to continue to cool flow.

What are the cost benefits of solar air conditioning?

If you’re planning to sell your home after the installation of solar air conditioning, your resale value will skyrocket. Studies show that for every dollar you save on energy, it will add another $20 to the value of your home. Another benefit is that there is roughly $1500 of savings depending on the models of solar air conditioner you install.

What are the disadvantages of solar cooling?

Solar panels for cooling are very weather dependent as they rely on the sun and its light. They can be fairly pricey to set up. They also are known to have expensive batteries and the square footage of your home may play a huge part in the cost as solar panels do not have a large power supply per panel.

The flip side of these disadvantages is that new, improved solar air conditioning systems are in constant development. These new systems offset the disadvantages.
