One approach is to use a multi-modeling approach based on black box models to represent the diurnal and nighttime phases of the day. Another approach is to utilize a fuzzy logic controller based on human perception of relative humidity and temperature. Additionally, the use of cooling systems assisted by effective control techniques has been found to be suitable for maintaining an appropriate climate inside the greenhouse. Nonlinear model predictive control (NMPC) frameworks have also been developed to simultaneously control multiple system states in the greenhouse climate. Furthermore, the use of actuators such as humidifiers and dehumidifiers controlled by fuzzy logic controllers has been explored to achieve optimal indoor humidity. These approaches aim to regulate the internal climate of the greenhouse, considering factors such as temperature, humidity, CO2 levels, and lighting.What are the unique energy demands of greenhouse environments?3 answersGreenhouse environments have unique energy demands due to factors such as heating, cooling, ventilation, lighting, and irrigation. Heating and cooling are particularly energy-intensive processes in greenhouses. The construction of greenhouses, typically made of light materials with poor insulation, contributes to the high energy requirements. Additionally, the internal climate of greenhouses often differs significantly from the external climate, especially during colder seasons. Despite the absorption of solar energy through passive solar systems, greenhouses still require a significant amount of fuel to maintain the desired temperature for crops. To optimize energy consumption and costs, it is important to focus on renewable energy resources and select the appropriate methods and equipment based on factors such as geographical area, climate conditions, crop production, and budget.What are the environmental impacts of food production?5 answersFood production has significant environmental impacts, including degradation of land and water resources, greenhouse gas emissions, deforestation, and reduction in biodiversity. These impacts are exacerbated by the increased demand for food due to population growth and dietary shifts towards animal-based products. The production, processing, distribution, and consumption of food directly influence human health and the environment. Agriculture, as the main source of food production, contributes to greenhouse gas emissions and pollution through the excessive use of fertilizers, pesticides, and herbicides. Livestock production, especially ruminant livestock, has a higher environmental footprint compared to plant-based food. Additionally, international trade plays a role in the environmental impacts of food systems, although it accounts for less than half of the total impacts. Overall, there is a growing evidence base that can inform initiatives to reduce the environmental impacts of food supply chains.What are the climatic features of the region that affect the growth of plants in greenhouses?5 answersThe climatic features of the region that affect the growth of plants in greenhouses include temperature, humidity, solar radiation, wind, and plant cover. Temperature is a crucial factor for the physiological development of plants, and a well-controlled temperature allows for optimal growth and development. Humidity levels also play a role in plant growth, as excessive or insufficient humidity can negatively impact photosynthesis and overall plant activity. Solar radiation affects the total solar radiation inside the greenhouse, which in turn affects the thermal characteristics and flow pattern inside. Wind direction and the use of insect-proof screens can also influence the microclimate inside the greenhouse, affecting factors such as airflow movement and overall climate. These climatic factors need to be carefully managed and controlled to ensure optimal plant growth and productivity in greenhouses.
