Abstract

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 paper provides details about the integration of the electrical/electronic component and the control system.

I. Introduction

The assessment results of the mechanical engineering program at Indiana University-Purdue University Fort Wayne have shown that the mechanical engineering curriculum lacks “high tech” equipment and experiments. The students have indicated that they would like to see more use of computer data acquisition systems and the availability of computers in the laboratories so they can perform on-site data analysis and calibration. Currently there is only one mobile data acquisition system that is rarely used in some of the laboratory courses. To address this concern, the engineering faculty at Indiana University-Purdue University Fort Wayne have integrated computer data acquisition in some of the existing and new experiments.

One of the new “high tech” laboratory experimental apparatus that was designed, developed, and constructed is a bench-top air conditioning processes demonstrating unit. 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. LabVIEW and computer data acquisition has been widely utilized to update and modernize equipment and laboratory experimental apparatus [1-5].
