Abstract
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 scaled down by 1/20. And rhodamine B was used as at temperature indicator. The intensity variations of LIF signal from Rhodamine B excited by the laser light sheet were captured with an optical filter and CCD camera. Laser light sheet of an Nd-Yag laser illuminated a two-dimensional cross section of the discharge region of air conditioner. The true temperature field data were derived from the intensity information acquired from LIF temperature calibration. The measured results for propagation of heat and flow in the room model are discussed in this paper.
