Heat Loss in the DeVries Hall Airlock
If you walk through the airlock at the main entry to the John "Doc" DeVries Hall on a sunny day you may notice the room is extremely warm. This webpage moniters the temperature in the room and calculates the amount of heat the radiator is contributing to the room. A single thermocouple measures the temperature inside the enclosure, while other sensors measure the outside temperature and the current solar flux.

The three main types of heat transfer: conduction, convection, and radiation are used on this page. The calculations performed with this information allows you to make a judgement as to whether or not Calvin needs to keep the heater on.
The data on this web page is generated by National Instruments LabVIEW software and FieldPoint data acquisition systems.
