Edible mushroom farming air conditioning

Edible mushroom farming requires precise control of environmental conditions such as temperature, humidity, ventilation, and CO₂ concentration. Industrial-scale mushroom farms rely on HVAC systems (Heating, Ventilation, and Air Conditioning) to optimize growth and ensure consistent yields. Key functions include:

  1. Temperature Regulation

    • Different species have specific requirements (e.g., button mushrooms: 16-24°C; oyster mushrooms: 20-30°C).

    • HVAC systems stabilize temperature to prevent stress during mycelial colonization and fruiting.

  2. Humidity Control

    • Mushrooms thrive in 85-95% relative humidity.

    • Integrated humidifiers/dehumidifiers prevent desiccation or fungal contamination.

  3. Ventilation & CO₂ Management

    • High CO₂ levels (>1500 ppm) inhibit cap development.

    • HVAC systems introduce fresh air and exhaust CO₂-rich air to maintain balance.

  4. Energy Efficiency

    • Modern systems use heat recovery and IoT sensors for real-time adjustments, reducing energy costs.

Case Study: In commercial button mushroom production, HVAC systems adjust temperatures phase-wise—23°C for spawn run and 16°C for pinning—while maintaining high humidity for optimal yield.
