Cooling Effect of Container Houses
The cooling effect of container houses is influenced by multiple factors such as insulation materials, refrigeration equipment, and structural design. With proper configuration, efficient cooling can be achieved to meet residential or storage needs.
Insulation materials are the fundamental factor affecting cooling performance. Conventional residential container houses adopt a three-layer structure to enhance thermal performance: the outer layer of anti-corrosion color-coated steel plate reflects sunlight, the middle layer of over 50mm polyurethane foam blocks heat conduction, and the inner layer of fire-resistant gypsum board combined with a moisture-proof film controls humidity and stabilizes temperature. 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-and-mortar walls. Measured data shows that in summer, the temperature inside the container rises 22 minutes slower than outside at noon, and in winter, the indoor temperature only drops by 1.3℃ after being closed for 8 hours. This delayed response characteristic makes the body feel more stable.
The selection and configuration of refrigeration equipment directly affect cooling efficiency. Professional mobile cold storages use Copeland semi-hermetic compressor units, which are energy-efficient and cost-effective. Paired with ceiling-mounted air coolers, they can achieve rapid cooling, and defrosting does not result in ice falling onto the goods. The intelligent control system can operate automatically and has multiple protection functions such as power phase loss, excessive current, and poor contact, effectively extending the service life of the compressor. For example, the mobile container cold storage produced by Lenglian Refrigeration has refrigeration equipment integrated into a standard container, with a compact structure and high cooling efficiency. It has flexible power requirements (both 380V and 220V are acceptable) and is suitable for scenarios such as construction sites and mobile restaurants.
Structural design optimization can further enhance the cooling effect. Some container houses reduce direct sunlight and hot air accumulation by adding aluminum foil reflective sandwich panels, adjustable sunshades, and bottom ventilation slots. For example, a double-decker container café in Moganshan adopts such a design, and the interior remains at a comfortable temperature without air conditioning even under direct sunlight in the afternoon. In addition, a closed design combined with an efficient refrigeration system and a power backup mechanism enables the container to adapt to complex environments such as high temperatures and high humidity, ensuring continuous and stable operation of the equipment.
