Industrial greenhouses

 

Ventilation system - the ventilation system is part of the roof structure of an industrial greenhouse. The system is designed for the implementation of natural air circulation and maintaining optimal temperature indicators, by opening / closing ventilation openings. The area of ​​the ventilation openings is about 20-25% of the roof area. The work of the system is ensured by gear rack with gears, rods, roller bearings. The angle of elevation is regulated depending on the air temperature, wind speed and amount of precipitation. The system works, as in the automatic mode, and is controlled remotely.

 

Heating system. According to the design and type of heaters, there are smooth-tube and converter water heating systems, air systems with concentrated distribution of thermal air and its distribution by means of air ducts, and combined heating systems. The most common is the piped heating system. Heat losses are compensated due to heating circuits: ground (heating the soil, preventing heat leakage from the soil through the foundations at low temperatures), underground (heating the substrate and the soil), top, side, sub-roofing. All heating circuits are connected by a group of pumps, which combines them into a single system. Adjustment can be made both as a whole system and along separate circuits, which contributes to the rational distribution of heat throughout the greenhouse volume. The pipe heating system is simple in design, creates a uniform temperature field, heats not so much the greenhouse, but the plants, thanks to the radiant component.

 

Shading system. In order to save energy and prevent overheating of air, when growing plants in greenhouses, horizontal and vertical shading systems are used. This system is able to reduce the consumption of thermal energy by 30-40% per year. Heat shields are designed to be transformed. In the daytime, they are formed with the help of special mechanisms, and in the dark period they unfold, ensuring the economical operation of the greenhouse. In the days of increased solar radiation, a shading method is applied. The vertical shading system is necessary for dividing the entire volume of the greenhouse into regulation zones, creating a more uniform and favorable temperature field and humidity for the plants.

 

The recirculation system is intended for artificial mixing of air in order to create an active climate, a uniform temperature field in the greenhouse volume, the elimination of areas with high humidity during the period when natural ventilation is ineffective or impossible. The system guarantees a uniform concentration of moisture and CO2 in the air (throughout the greenhouse) and improved gas exchange of plants. The system works automatically.

Irrigation - water and food system. The most popular method of irrigation - drip. The aqueous solution is fed in uniform small doses directly into the root zone. Watering in small portions, several times a day contributes to the favorable absorption of moisture and nutrients. The drip irrigation system has a number of significant economic advantages: reducing labor costs for watering and processing; saving water and fertilizer; yield increase for a number of crops in 1,5-2 times.

Drainage waste reuse system - the system is designed for collecting, processing and recycling drainage waste. The drainage collection system is connected to the irrigation system, and the drainage is biologically decontaminated before reuse. This system allows you to use 20-30% of the volume of the nutrient solution in the second turnover.

Evaporative cooling and air re-humidification system. The system is designed to reduce air temperature and maintain the required level of humidity in the greenhouse. The creation of a certain pressure in the system, it is necessary for the formation of a small-drop spray. This condition allows evaporative cooling and air moistening in greenhouses without droplets on the leaves.

Assimilation lighting system (electric lighting). The system is necessary to provide the necessary intensity of natural light. Management is carried out on the basis of solar radiation indices and time of day, using an automation system based on the specified agrotechnical parameters.

Automated climate control system and mineral nutrition - the system is necessary to ensure and maintain with high accuracy the specified climatic regimes, by acting on the actuators and equipment of a number of technological systems. The automatic control system provides an increase in yield, obtaining complete and accurate technological information, saving 15-30% of heat, improving working conditions and production culture.
Cogeneration is the process of the joint generation of heat and electricity during fuel combustion.

CO2 plant feeding system - The system is necessary to provide the necessary CO2 content in the gas mixture, which contributes to an increase in the yield of vegetables. Low carbon dioxide content is a factor that limits yield. The standard scheme for feeding plants with CO2 is the use of boiler house off-gas, which contains about 9–11% CO2. Due to automation, it became possible to dose all CO2
The roof washing machine is used for external cleaning of the glass coating of an industrial greenhouse. To install the machine used rails.
