Container House Temperature Test
The temperature test of container houses requires a comprehensive evaluation based on their structural characteristics, material properties, and actual environmental conditions. Their thermal insulation performance is generally superior to that of traditional temporary buildings, but achieving a warm winter and cool summer effect requires reasonable design and material selection.
1. Thermal Insulation Structure and Materials Are Key
The thermal insulation performance of container houses primarily depends on their wall structure and materials. For example, residential container houses adopt a three-layer structure: 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 and moisture-proof film work together to control temperature. This structure results in a wall heat transfer coefficient of ≤0.45W/(㎡·K), equivalent to 1.8 times the thermal insulation efficiency of traditional brick-and-mortar walls. Measured data shows that in summer, the cabin warms up 22 minutes slower than the outdoors at noon, and in winter, the indoor temperature drops by only 1.3℃ after being sealed for 8 hours, providing a more stable perceived temperature. Additionally, Zeyu Container House's sandwich-structure walls (outer layer of color-coated steel plate + middle layer of rock wool insulation + inner layer of fire-resistant board) have been tested in high-temperature regions such as Africa and the Middle East, showing that the indoor temperature can remain stable below 28℃ in summer, with a temperature difference exceeding 18℃, demonstrating significant energy-saving effects.
2. Environmental Adaptability Affects Temperature Performance
The temperature performance of container houses needs to be considered in conjunction with specific environmental conditions. For example, in the earthquake-stricken area of Linxia, Gansu, where the minimum winter temperature reaches -17℃, container houses can quickly raise the indoor temperature to above 20℃ through pre-embedded water and electricity pipelines and the installation of temperature control equipment such as air conditioners or graphene floor heating. In high-temperature and high-humidity areas, such as outdoor container houses in Jiujiang, which adopt a composite structure of a 120mm thick reinforced concrete shell and a 30mm extruded polystyrene board, measured data shows that the indoor surface temperature in summer is 8.6℃ lower than that of color-coated steel plate houses, with a heat transfer coefficient of 0.41W/(㎡·K), surpassing green building standards.
3. Design Optimization Enhances Temperature Control
Through design optimization, the temperature adaptability of container houses can be further improved. For example, adding double- or triple-glazed windows and seals reduces heat leakage; using adjustable sunshades and bottom ventilation slots promotes air circulation; or forming family suites through modular combinations, utilizing spatial layout to improve ventilation and lighting. Additionally, Jiangxi Sixun Construction Engineering Co., Ltd. uses containers as mold carriers and implements full concrete casting inside, completely avoiding the issues of fast heat conduction and poor sound insulation of metal containers while retaining the advantage of rapid deployment.
