How to Dissipate Heat in Container Houses

Container houses can achieve effective heat dissipation through optimizing insulation structures, increasing ventilation designs, using temperature control equipment, and reasonably arranging sunshade facilities.

1. Optimize Insulation Structures

The insulation performance of container houses directly affects heat dissipation. The outer layer uses anti-corrosion color-coated steel sheets to reflect sunlight, the middle layer is filled with polyurethane foam layers over 50mm thick to block heat conduction, and the inner layer uses fireproof gypsum boards and moisture-proof films for coordinated temperature control, which can significantly reduce heat transfer. For example, the national 'Technical Standard for Steel Structure Integrated Houses' requires that the heat transfer coefficient of residential container walls be ≤0.45W/(㎡·K), which is 1.8 times the insulation efficiency of traditional brick-concrete walls, effectively delaying the temperature rise inside the container. In addition, increasing the foam thickness or selecting materials such as rock wool and silicate wool can further enhance insulation performance and reduce heat accumulation.

2. Increase Ventilation Design

Ventilation is a key means of heat dissipation. Setting ventilation slots at the bottom and installing adjustable sunshade roofs at the top can create natural convection and accelerate the expulsion of hot air. For example, a café in Mogan Mountain uses sandwich panels with aluminum foil reflective layers, combined with bottom ventilation slots, to keep the interior cool even under direct afternoon sunlight. When designing staggered floors or stacking containers vertically, leaving recreational courtyards or aisle areas at the bottom can also improve ventilation and prevent heat retention.

3. Use Temperature Control Equipment

For scenarios with high equipment heat generation or sensitivity to ambient temperature, installing dedicated air conditioning systems is an efficient solution. For example, the BattCool-AF series energy storage container air conditioner uses DC inverter technology, supports wide-temperature operation from -30 to 55℃, and can quickly cool down and stabilize temperature and humidity. Built-in or external installation methods can be selected according to needs, ensuring complete isolation between the internal and external environments and preventing heat backflow.

4. Reasonably Arrange Sunshade Facilities

Roof eaves, terrace sunshades, or adjustable sunshades can block direct sunlight and reduce roof temperature. For example, when installing large floor-to-ceiling windows or roof skylights, combining them with sunshade facilities can ensure both light transmission and avoid summer overheating. Using paint spraying, themed murals, or glass curtain walls on the exterior facade can also reflect some sunlight and reduce heat absorption while beautifying the appearance.
