HEATING AND COOLING OF GREENHOUSE
PROPOSALS TO INCREASE EFFICIENCY AND REDUCE COSTS
The heating systems are numerous and have evolved in relation to:
– Cost of energy (fossil or renewable);
– Economic value crops (vegetables, flowers, PDO, …);
– Different needs of the crop (plant t ermofile or cold-tolerant);
– Different cultural practices (growing on the ground, on pallets, in pots, soil …);
– What to type (greenhouses, tunnels).
