Abstract

Danfoss Turbocor specializes in making HVAC compressors. The electronic parts of the compressors are tested in an environmental test chamber, with extreme temperatures that range from -40°C to 160°C. The design of the chamber makes it difficult to see the parts inside during testing. In order to achieve better failure detection, our team is designing an enclosure for a camera that is placed inside the chamber.

Tests inside the chamber can last up to 80 days, so basic insulation alone is not enough. Typical cameras work between 0°C to 45°C. To meet desired temperatures, we are using basic insulation and constant air exchange to help regulate the temperature inside the camera enclosure. Constant airflow through the enclosure removes and adds heat as needed, keeping the camera operational.

The camera records videos of the parts and stores them for later use. Camera view angles are adjustable for specific tests. With our design, Danfoss employees can determine when and how the parts fail.
