Module Description
This module focuses on the critical role of integrated Energy and Thermal Management Systems in modern greenhouse agriculture. As the Mediterranean region and the world face the dual challenges of climate change and rapid population growth, traditional farming methods are becoming increasingly vulnerable. This module explores how controlled-environment agriculture (CEA) acts as a climate buffer, ensuring food security through precise environmental regulation. Learners will delve into the biological responses of plants to thermal stress, the physics of greenhouse energy balances (including solar radiation, convection, and transpiration), and the engineering of sustainable energy solutions like hybrid microgrids and heat pumps. The module emphasizes the transition toward a sustainable, high-tech agricultural economy that minimizes environmental impact while maximizing local food production.
Learning Outcomes
- Evaluate the physiological impact of extreme temperatures (frost and heat stress) on crop health and yield.
- Analyze the complex energy balance of a greenhouse, accounting for solar gain, convective losses, and latent heat flux from transpiration.
- Design a conceptual integrated management system that balances thermal needs with sustainable energy generation and storage.
- Assess the trade-offs in plant stomatal regulation between water conservation and thermal cooling.
Key Content Topics
• The Global Context: Population growth, climate change, and the need for protected cultivation.
• Plant Biology under Stress: Mechanisms of frost damage, heat stress, and stomatal regulation.
• Greenhouse Physics: Energy balance modeling, including solar radiation, soil convection by ground multi-layer simulation, and the Penman-Monteith equation for transpiration.
• Thermal Management Solutions: Active and passive heating/cooling systems (Heat pumps, PCMs, evaporative cooling).
• Energy Management & Sustainability: Hybrid power strategies, microgrids, and renewable energy integration.
Contextual Examples:
- Heat Pump Sizing: A practical case study on calculating the required capacity for a greenhouse based on regional Mediterranean climate data.
- Hybrid Microgrid Simulation: An example of a greenhouse powered by a combination of PV panels, battery storage, and a backup generator to ensure 24/7 thermal stability.
- Transpiration and Multi-Layer Soil Modeling: Using the Penman-Monteith equation to predict cooling requirements in a high-humidity Mediterranean summer.
