A portable experimental setup for demonstrating air-conditioning processes was designed, developed and constructed by a multidisciplinary capstone senior design team. This experimental apparatus is currently being used to demonstrate to undergraduate students air-conditioning processes such as cooling, heating, and humidification. The level of cooling, heating, or humidification is being monitored and controlled using a PC-based control system which consists of LabVIEW and data acquisition unit. This article provides details about the integration of the electrical/electronic component and the control system. © 2009 Wiley Periodicals, Inc.
