Abstract

To assess the feasibility of night-day storage of solar energy in greenhouses, two identically heated greenhouses of 185 m2 have been constructed near Livorno (Italy). One served as a reference while the other was equipped with a system of solar energy storage based on phase-change material (PCM) with a low melting point (21 C). The PCM, called `serrolithe', is a mixture of hexahydrated calcium chloride capable of absorbing 135 KJ/kg during the melting, which takes place from 19 to 23 C. The measurements taken during the 1984/85 and 1985/86 winters have enabled the drawing up of the heat balance of the greenhouses, showing substantial energy saving brought about by this system of solar energy storage. The growth of ornamental plants (phyllodendron, aralia, cyclamen) cultivated identically in the two greenhouses was also measured.
