| Summary: | 碩士 === 大華技術學院 === 機電研究所 === 99 === In general, containers are loaded and sealed intact onto ships, railroad cars, planes, and trucks. In recent years, a converted container used as an office at a building site. Shipping container architecture is the use of containers as the basis for housing and other functional buildings for people, either as temporary housing or permanent, and either as a main building or as a cabin or workshop. Containers can also be used as sheds or storage areas in industry and commerce. The widespread use of containers has driven modifications in ventilation, gradually forcing ventilated device into the concept of energy saving and carbon reduction, and changing completely the widespread use of air conditioner that fit into the window of containers. Containers are generally made of metal plate with high thermal conductivity, when the container is exposed to solar radiation under the sun, the temperature in the container will reach quickly above 50℃ as a result of the thermal radiation and heat conduction. The high temperature in the container harm seriously the human body's health. The high temperature in the container is also rather notable to the influence of energy consumption. The people use the container so frequently that the people pay great attention to thermal comfort of container compartment. In order to improve the thermal comfort within container compartment, people require a detailed understanding of the reducing temperature within container compartment.
This project present an creator to improve the thermal comfort of container compartment, the three methods include: Method 1 is to use the device design produce natural thermal convection, Method 2 is to drive fan produce forced thermal convection, and Method 3 is to use sprayer absorb heat of vaporization. The experimental results show that the three methods reduce the compartment temperature about 8.8℃~18.2℃ (Method 1), 20.6℃~24.6℃ (Method 2) and 14.9℃~15.7℃ (Method 3) respectively. Compared with the results in the same experimental conditions, the temperature within the automobile compartment of Method 2 is found to reduce greatly, the Method 1 and the Method 3 are relatively small. Hence, we can conclude that the thermal comfort is improved effectively by forced convection.
