Vaisala will present a session on relative humidity and dew point theory in the ARBS exhibitor presentation theatre this week.

It will be presented by Anthony Ulrich, senior sales manager for ANZ at Vaisala.

He will explain humidity, fog, mist and steam as well as condensation and moisture.

Dalton’s Law will be covered by Ulrich as well as information on selecting the right humidity parameters.

The presentation theatre provides exhibitors with an opportunity to demonstrate technology or provide information on specific areas of HVACR.

Other exhibitors utilising the theatre include ebm-papst, Big Ass Fans, ABB, A-Gas and Midea.

Big Ass Fans engineer, Ario Narisworoputro, will use SpecLab software to map airflow.

The cloud-based, comprehensive configurator allows users to build and specify airflow solutions in a level of detail never before possible.

Narisworoputro will use computational fluid dynamics (CFD) and propietary airflow data collected at Big Ass Fans' research facility.

He will show how air speeds and air turnovers per hour (ATH) can create greater air distribution and occupant comfort.
