Fridge Ventilation Requirements for Campervans

A compressor fridge needs ventilation to work efficiently. Without it, the fridge runs continuously, drains your battery, and can overheat.

Why It Matters

Compressor fridges generate heat at the back (the condenser coil). This heat must be dissipated. If the heat builds up in an enclosed cabinet, the fridge works harder to maintain temperature, consuming up to 50% more power.

Ventilation Requirements

• Air gap: Minimum 100mm behind the fridge, 50mm above, 50mm below
• Vent openings: Total 200cm² (top and bottom), roughly 10x20cm each
• Grilles: Use dedicated fridge grilles (screwfix, £5-15)
• Fan: Optional but recommended for summer. A 12v computer fan (120mm, £8) wired to a thermostat switch.

Installation

1. Build the fridge cabinet with the required air gaps
2. Cut upper and lower ventilation grilles
3. Ensure the lower grille draws cool air from inside the van
4. Ensure the upper grille exhausts to the outside (or to a high point in the van)
5. Fit a 12v fan wired to a thermostat if desired

Conclusion

Do not skimp on fridge ventilation. A well-ventilated fridge uses half the power of one suffocating in a sealed cabinet.
