APPARATUS FOR COORDINATING OPERATION OF VDENTINATION SYSTEM AND GENERATOR OF CARBON DIOXIDE IN HOTHOUSE

摘要

The invention relates to agriculture, more specifically to industrial crop production under greenhouse conditions. The purpose of the invention is to optimize the plant photosynthesis process and save natural gas. A device for coordinating the operation of a ventilation system and a carbon dioxide generator in a greenhouse contains actuator control systems providing natural ventilation and air saturation of the greenhouse with carbon dioxide. The glass roof of a greenhouse 2 has transoms equipped with reversible drives. The temperature of the air in the greenhouse is controlled by sensor 4 in the plant zone, and sensor 5 in the zone under the transoms 1. The concentration of carbon dioxide is monitored by sensor 31, and the irradiation of plants is controlled by sensor 32. The device includes computing units 7, 22, the controller torus 15 transom 1, carbon dioxide generator 26, two-position regulator 25, impulse regulators 13, 23, and matching blocks 14, 24. During operation, the device closes transoms 1 during the operation of the carbon dioxide generator 26 in the greenhouse, taking into account values of air temperature in two zones of the technological object, the concentration of carbon dioxide in the air and the irradiation of plants. 2 hp f-ly, 8 ill.
