Abstract
A properly designed room air diffusion scheme ensures that when conditioned air is supplied into a room, it causes no discomfort to the occupants. To confirm the design characteristic of an air diffusion arrangement a measurement of different parameters of air movement pattern like jet geometry, air temperature and velocity or humidity must be done. IR thermography can be successfully applied for quick determination of the air jet geometry, not only for new and existing systems, but also in the design phase of air inlets and outlets. The paper presents the possibilities for the determination of jet geometry, radius and spread by means of IR thermography.Ispravno projektiran sustav za distribuciju zraka u prostoriji osigurava stanje ugode osobama koji u njoj borave. Da bi se potvrdili parametri koji karakteriziraju tu distribuciju, potrebno je izvršiti određena mjerenja poput geometrije mlaza, temperature, brzine i vlažnosti zraka koji se ubacuje u prostor. IC termografija se može uspješno primijeniti ne samo za brzo određivanje mlaza kod novih i postojećih sustava već i kod konstruiranja usisnih i odsisnih elemenata. Radom su prikazane mogućnosti određivanja geometrije mlaza kao što su domet i širina upotrebom IC termografije
