Enclosure: Must use polyurethane/rock wool sandwich panels (thickness ≥100mm, thermal conductivity ≤0.024W/m·K), seamless joints for walls/ceilings, and double-glazed thermal break aluminum sealed doors to ensure airtightness with air changes ≤0.5 times/h (non-operational) or as needed.
Temperature & Humidity Control Precision: Reserve independent hot/cold source pipes and air ducts. Temperature range typically -20°C to 60°C (accuracy ±0.5°C), humidity 10% to 95% RH (accuracy ±2% to 5%). Floor must have waterproofing + drainage slope to prevent condensate accumulation.
Lighting System Installation: Reinforce ceiling to support full-spectrum LED plant light arrays (with PAR adjustment). Lights must have water-cooled or low-heat design. Wiring needs independent circuits with dimming/photoperiod programming interfaces to avoid heat radiation interference.
Gas & Fresh Air: Embed CO₂ supply and exhaust pipes in walls. Fresh air system air changes ≥10 times/h. Inlet must have filtration and temperature/humidity pretreatment to prevent external fluctuations.
Floor & Wall Materials: Use epoxy or anti-slip acid/alkali-resistant flooring (easy to clean, washable). Walls must be smooth, mold-resistant, and corrosion-resistant (avoid regular latex paint or wood finishes). Corners should be rounded to prevent dust accumulation.
Thermal Bridge Treatment: All panel joints and pipe penetrations must use foam filler + insulation tape sealing to prevent condensation and mold from thermal bridges.
Electrical Safety: All outlets and switches in high-humidity environments must meet IP54 or higher protection rating. Wiring conduits need moisture-proofing. High-power lights and AC units require independent three-phase power supply.
Zone Isolation: If including sterile operations or different climate zones, install buffer rooms and air showers, maintaining slight negative or positive pressure to prevent cross-contamination.
Smart Central Control: Reserve space for a central control cabinet, integrating PLC/SCADA systems for real-time data collection and automatic feedback regulation of temperature, humidity, light, and air.
The core of plant climate chamber renovation lies in high airtightness enclosure, precise independent environmental control systems (temperature/humidity/light/air), and anti-condensation and anti-corrosion structures, far from ordinary interior decoration.
