• Our intent is to measure the ambient radiant temperature and the dry bulb temperature of the main living space.  For reference we also recorded outdoor temperature and the surface temperature of the stove.
  • We used eight Hobo XT Dataloggers to record our data.  The Hobo XT is a portable, self-contained datalogger the size of a box of matches.  These miniature data acquisition systems have many applications.  They record dry bulb temperatures that can be down-loaded and interpreted using specialized computer software.
  • Three Dataloggers were adapted to record mean radiant temperature by inserting the sensor into a black plastic toilet floater.  The short-wave radiation is absorbed by the black mass of the floater.  The act of absorbing converts this radiation to heat.  As the floater heats up it transfers heat to the surrounding air through convection.  The air temperature inside the floater then increases and is a good measure of radiant air temperature of the room.
  • The measurements will be taken in four stations(each with two Hobos, one measuring radiant and one dry bulb temperature), starting at the stove and moving to the back wall at six foot intervals.  The sensor of the Hobo at the stove was taped to the front surface of the stove.  The eighth Hobo was used to measure the outdoor temperature.
  • The Hobos were set to record data every two minutes for a twenty-four hour period.
  • We expected to observe a difference between the radiant and dry bulb temperatures where the dry bulb would be lower.  We also expected the zones closer to the stove to be warmer than the outer zones.  Furthermore, we expected the ambient radiant temperature to remain within the parameters of the comfort zone as defined by the psychrometric chart.  We anticipated a correlation between the surface temperature of the stove and the radiant temperature of the room.
