Greenhouses of the 5th generation Active Climate analogue of Ultra Clima greenhouses
Description of the 5th generation Active Climate Active Air greenhouse
|
1 |
Significant height of the structures equal to 7 meters allows you to increase the distance between the roof and the tops of plants. |
|
2 |
Thanks to the use of recirculation and conditioning of the indoor air of the greenhouse, there is virtually no need for small ventilating windows located on the roof. The number of ventilating windows is reduced by 90%, compared to classic greenhouses. Increased illumination contributes to increased yield. The risk of pest entry is also significantly reduced. |

The greenhouse is constantly under slight excess pressure, and all process openings and ventilation windows are equipped with mosquito nets, which also prevent the penetration of pests. |

A heating system with distributed air flows through the air hoses provides precise climate control. The concentration of CO2 is uniform throughout the greenhouse, temperature deviations in both horizontal and vertical planes are 1-2 Co, which in itself is a serious technological achievement. |

5 |
Air conditioning allows you to cool the greenhouse in summer. |
|
6 |
Lamps of artificial lighting in addition to light emit heat. Its volume reaches up to 90% of the lamp power. The use of this heat repeatedly by the greenhouse microclimate control system significantly reduces heating costs.
Summarizing the features of Active Climate technology, we can emphasize that this set of technologies can reduce heating costs by 25% and increase yield by 20%.

Active climate
1. The greenhouse maintains an ideal microclimate at any time of the year.
2. In winter or spring, during overheating, as well as in ordinary greenhouses, the ventilating windows are slightly opened, although the number of these windows is by 90% less than in ordinary greenhouses and they are only used to remove the slight excess pressure in the greenhouse. At the same time, air always leaves the greenhouse, and here a thermal shock is not possible, and since there is a small number of ventilating windows the heat loss is less.
3. In summer, the greenhouse is capable of cooling itself. It is equipped with adiabatic panels to which the water flows. Water, evaporating, takes part of the energy and thus cooled air enters the greenhouse.
Automatic control
1. A greenhouse can maintain an optimal level of CO2 at any time.
It is known that during the period when it is necessary to open the ventilating windows, it is not possible to maintain the level of CO2 required for the technology in a simple greenhouse. It always strives for a natural background in the street, which is about 400 ppm. This level of CO2 is insufficient for complete photosynthesis, which leads to loss of yield. In the 5th generation greenhouse, due to its “semi-closed design", it is possible to maintain the required concentration of CO2 to a much greater extent, and this has a beneficial effect on yield.
2. The greenhouse is protected from pests.
One of the features of the 5th generation greenhouse is the presence of excess pressure inside. When opening the ventilating windows and the entrance gate, insects cannot overcome the force of excessive pressure and do not enter the greenhouse.
Energy efficiency
- This happens due to reuse of thermal energy. In an ordinary greenhouse, warm air rises up from the heating pipes and exits through the glazing of the greenhouse roof, moreover, the greater the temperature difference between the external and internal air, the higher the transpiration rate. Naturally, in winter the heat consumption is the maximum one. In the 5th generation greenhouses, warm air rising up is taken off by the fans and again fed for heating via plastic hoses located under each bed. This effect is especially enhanced when using a photoculture technology. The lamp heat, which is about 90% of the lamp power, in a simple greenhouse irretrievably disappears, and in the 5th generation greenhouse it is almost completely used for heating.
