Valorisation des rejets d'eaux tièdes : principes généraux d'utilisation pour le chauffage des serres

The benefits of low temperature greenhouse heating systems are outlined and the major types of heating system are discussed. Computer software was used to simulate the thermal behaviour of greenhouse, in order to determine the most suitable heating system for utilization of tepid water. Heat consumption of the different systems was calculated and values are tabulated. The best system for tepid water utilization was a pulsed air system with ducts at soil level, which was able to provide 96-99% of the energy required for heating. / Chauffage d'appoint, dans les serres, réalisé à l'aide d'un réseau d'eau chaude
