Definitions

  • the invention relates to devices for circulating air in greenhouses, hotbeds, etc. in order to regulate the temperature of the soil and air when germinating seedlings and growing plants.
  • the disadvantage of this device is that the heating of the earth under the plants due to the warm air coming from located on the soil surface of the duct is ineffective: warm air rises upward, respectively, the soil will be heated to a shallow depth and the roots of the plant will not receive enough heat. Warm air directed to the plant itself also tends to rise up without reaching the plant and cannot sufficiently heat it throughout its height.
  • the disadvantage is the lack of circulation of warm air in the greenhouse - air is taken only from the outside of the greenhouse and there is no re-intake of it. This leads to significant heat loss and energy consumption.
  • the purpose of the invention the provision of complete heating of plants in greenhouses over the entire height with minimal heat loss.

Abstract

Le dispositif pour la circulation d'air dans les serres comprend un ventilateur, un réchauffeur et des conduites d'air et comprend également une plaque présentant des plis et possédant dans la partie supérieure des plis des fentes alternées pour l'amenée et l'évacuation du flux d'air; une plaque possédant des orifices destinés à la répartition de flux d'air chaud via les fentes de la plaque plissées et la plaque pour le retour d'air dans le système. L'invention vise à assurer un degré de réchauffement adéquat dans des serres pour plantes sur toute la hauteur et à réduire au minimum les pertes de chaleur et d'énergie.
