Solar cold: solar panels produce cooling for air conditioning

Getting cold from the heat seems like a contradiction but years of research and experimentation make it possible. The "solar cold”Can be obtained in two ways:

• Achieving that the energy generated by the sun collected in photovoltaic panels activates the equipment that generates cold.
• Through solar collectors that produce thermal energy at low or medium temperature.

A pioneer company in this technology is climatewell, a Swedish-Hispanic firm that developed a system in which it is possible to collect energy and convert hot water into cooling and heating without resorting to electricity.

The mechanism, known as solar cold decongests the electrical system and optimizes the operation of the solar With the advantage that it is when it is hotter when more energy is accumulated than is required to run air conditioners, it is the hottest hours when more energy is required to cool the environment.

Solar cooling technology works by transforming the solar energy accumulated in photovoltaic panels cold to cool the interior of the houses in summer. Additionally, the same This system is useful for obtaining domestic hot water throughout the year and for heating the house in winter.

In the solar cooling system in an ecological way, savings are achieved due to the fact that reduces electricity consumption And as it comes from clean energy, it does not produce emissions that are harmful to the environment, such as CO2, which cause climate change.

For now, there are about 150 solar cooling facilities, of which almost 100 units are located in Europe, the majority in Germany and countries located on the Mediterranean coast where the sun is present for a greater number of hours a year.

It is expected that in Spain the boost given to ecological energies by the Renewable Energy Plan (PER 2005-2010) and the Technical Building Code, CTE, help the solar cold have a greater development in the country. The standards established in both documents require minimal applications of solar energy in new construction.
