📚 1. Understanding Geothermal Energy in Greenhouses 🌍🌡️

Geothermal energy utilizes the constant underground temperatures to regulate greenhouse environments. Unlike traditional heating and cooling systems, geothermal systems provide consistent performance year-round with minimal environmental impact.

✅ How Does Geothermal Energy Work in Greenhouses?

1. Heat Extraction: During colder months, heat is extracted from the ground and circulated into the greenhouse.
2. Heat Dispersion: In warmer months, excess heat is transferred back into the earth.
3. Temperature Regulation: Stable underground temperatures ensure consistent heating and cooling.

Best For: Greenhouses in regions with harsh winters or extreme temperature fluctuations.

Key Components:

• Geothermal Heat Pump (GHP)
• Ground Loop System (Horizontal or Vertical)
• Distribution System (Pipes, Vents, Radiant Floors)
