Abstract
The last two decades a lot of efforts have been done by the researchers in different countries in
order to study the possibilities of using solar energy for heating greenhouses. From these research works hundreds of solar systems have been developed, but out of these very few found practical application. The passive solar system with the water filled plastics tubes and the system of spraying water on the top of the greenhouses are the only solar systems adapted by some growers of the greenhouses in the Mediterranean region. In Japan the earth - air heat exchange system found also some practical applications. Today many researchers have focused their interest on the improvement of the efficiency of the passive solar system, which has already passed to the growers, on the study of the response of different greenhouse crops to this solar system and on the modifications of this solar system to different climatic zones and different greenhouse structures. In this paper the problems of using solar energy for heating greenhouses and future perspectives are discussed.
