Untersuchung der Ausströmungshomogenität einer klimatisierten Matratze - Investigation of the airflow homogeneity of an air-conditioning mattress

Abstract

Air-conditioning mattresses are used in the treatment of sleep disorders, as temperature and humidity discomfort are among the most common complaints of those affected. In the devel-opment of a new type of air-conditioned mattress with an integrated control function, the aim is to achieve a homogeneously distributed air outflow to ensure a cooling effect with simultane-ous removal of humidity caused by sweating. This paper describes the experimental approach for the optical measurement of the air velocity above the surface of the mattress. For the eval-uation of the raw images, a transit-time method is presented as an alternative to the conven-tional stereoscopic Particle Image Velocimetry (stereo PIV). The results of both methods are discussed to analyze the air flow of the mattress.
