Description:
Public Technical University whose main core research activities are related to industrial, telecommunications and agro-food issues, has developed a photovoltaic evaporative tower (chimney) with a dual functionality.

Firstly, the cooling of a photovoltaic panel is achieved by an air stream by its rear face, and at the same time it is used as heat dissipation system of a refrigeration cycle. To accomplish this purpose, the system is divided into two main parts. Following the path of the air inside the first section, called evaporative zone, it has a series of nozzles which atomize water in parallel flow with the air descending. As the water falls, a small part evaporates cooling the rest. This section works as a small-scale cooling tower. The air, that has been in contact with water has increased humidity, and may even have reduced its temperature (depending on operating conditions). This air begins to rise due to the flotation effect in the so-called convective zone. This second area is basically a solar chimney in which the heating of the air causes flotation of the same. In turn, the ascending air through the convective section cools the photovoltaic panel increasing its yielding.

Quite interesting competitive advantages can be achieved by companies that exploit this new technology regarding both low technical complexity of the system and its low cost in terms of production.

Researchers are looking for license agreements with energy sector companies willing to manufacture and commercialize the technology. They are interested in contacting with companies working in the fields of energy, energy efficiency, acclimatization, etc.
Advantages and Innovations:
Attempts carried out to date for the use of solar energy in air conditioning systems have been based on technologies for thermal facilities medium and large (> 50kW ). In these systems, solar panels, flat or vacuum, received solar radiation and converted it into thermal energy by means of fluid heating. This fluid was used in an absorption or adsorption system to produce air conditioning.

However, due to technological reasons, as hydraulic complexity and control of such systems, and mainly to economical reasons, its implementation has been limited.

The invention described herein, seeks to improve the efficiency of a photovoltaic panel through evaporative cooling, this combined with the use of a water-condensate air conditioning system. The technical characteristics of this system lead to an efficient solar air conditioning design.
