Why do smart lockers have air holes?

Smart lockers incorporate air holes (ventilation slots) for critical functional and safety reasons, detailed below:

1. Prevent Temperature/Humidity Buildup
Condensation Avoidance: Trapped warm air meeting cooler locker surfaces causes moisture buildup, risking mold or damage to paper/electronic items.
Heat Dissipation: Electronics (e.g., power banks) left inside could overheat without airflow, creating fire hazards.

2. Ensure Basic Air Circulation for Living Organisms
Accidental Pet/Insect Entry: Small animals or insects may enter lockers during loading. Ventilation provides oxygen to prevent suffocation.
Biological Safety: Perishable items (food, plants) decay faster in stagnant air, producing odors or harmful bacteria.

3. Pressure Equalization
Door Operation Stability: Sudden air pressure changes (e.g., slamming doors) can create suction/vacuum effects. Vents allow air intake/escape, easing door closure.
Altitude Adaptation: In high-elevation areas, vents prevent air pressure imbalances that could warp doors or strain locks.

4. Chemical Fume Dispersion
Material Off-Gassing: Newly manufactured items (e.g., plastic, treated fabrics) may release volatile compounds. Ventilation dilutes concentrated fumes.
Cleaning Residue: Residual disinfectants used on locker interiors could emit irritants without airflow.

5. Compliance with Safety Standards
Child Safety Protocols: International standards (like ISO) mandate ventilation to mitigate suffocation risks if children enter lockers.
Transport Regulations: Lockers used for logistics must align with cargo-container ventilation norms.
