The spatial variations of temperature field around the room air conditioner
model were measured using the LIF(Laser Induced Fluorescence) temperature
field measurement technique. The room model and air conditioner model are s
caled down by 1/20. And rhodamine B was used as a temperature indicator. Th
e intensity variations of LIF signal from Rhodamine B excited by the laser
light sheet were captured with an optical filter and CCD camera. Laser ligh
t sheet of an Nd-Yag laser illuminated a two-dimensional cross section of t
he discharge region of air conditioner. The true temperature field data wer
e derived from the intensity information acquired from LIF temperature cali
bration. The measured results for propagation of heat and flow in the room
model are discussed in this paper.
