Container House Temperature Test Chart
Currently, there are no directly publicly available temperature test charts for container houses, but their temperature performance can be indirectly understood through their insulation structures, measured data, and experimental research.
Impact of Insulation Structures and Materials on Temperature
The insulation performance of container houses mainly relies on their 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 humidity and stabilize temperature. For example, Zeyu Housing uses 50mm-thick Class A fire-resistant rock wool color-coated steel sandwich panels, paired with galvanized steel plates to form double-layer protection. The outer wall is coated with nanoscale reflective materials, with a sunlight reflectance of over 85%, which can reduce the surface temperature of the container by 22℃. The overall heat transfer coefficient K value is ≤0.38W/(m²·K), and the temperature difference inside the container is controlled within ±3℃ under extreme temperature differences of 100℃.
Temperature Changes Reflected by Measured Data
Measured data shows that the temperature rise inside a container house is 22 minutes slower than that outside at noon in summer, and the indoor temperature only drops by 1.3℃ after being sealed for 8 hours in winter. This delayed response characteristic makes the body feel more stable. For example, a café in Moganshan uses sandwich panels with aluminum foil reflective layers, paired with adjustable sunshade canopies and bottom ventilation slots. When exposed to direct sunlight in the afternoon, the interior can remain comfortable without air conditioning. In addition, experiments on radiation cooling coatings for metal containers show that under Hong Kong's climatic conditions, the surface temperature of a container office using radiation cooling coatings can be reduced by 18℃, and air conditioning power consumption can be saved by 23.5%.
Temperature Monitoring Technology in Fire Experiments
In container fire temperature measurement experiments, multi-channel temperature testers are used to monitor the temperatures at multiple points in real-time, providing fire information to support fire prevention and control. This equipment features high precision, multiple channels, and real-time monitoring, and is capable of recording and storing temperature data to help analyze fire development trends. Although this application scenario is different from residential temperature testing, it demonstrates the technical feasibility of temperature monitoring inside containers.
