An analytical study describing the performance of a tunnel greenhouse drier is presented. Considering the greenhouse as a solar collector, a linear function between the incident solar radiation and the greenhouse output temperature is obtained. Using the drier characteristic function, the drier...

In the present paper a low cost solar active water heating system is proposed to increase the average night temperature and avoid freezing problems inside greenhouses. The system collects the excess of energy in the greenhouse during the day, and returns it at night. The most important part of...

Renewable energy sources are considered as strategic opportunities to improve the population's quality of life, to promote the development of more efficient and equitable economic systems, and to favor environmental sustainability in the territorial planning of Lerma Valley (Salta, Argentina)....
