Development of a Psychrometric Test Chamber

Michael J. Swedish

Associate Professor Mechanical Engineering Department Milwaukee School of Engineering


The design of the Psychrometric Test Chamber was done as a Senior Design Project by undergraduate students Brent Losey and Joseph Stellbrink, under the supervision of Professor Swedish.

Funds for the construction of the Psychrometric Test Chamber were provided through a grant from the A. O. Smith Foundation.

I. Introduction

The purpose of this paper is two-fold:

- To illustrate the incorporation of the capstone design experience into the development of laboratory equipment.

- To describe the capabilities and operation of the psychrometric test chamber.

II. Engineering Design and the Energy Laboratory at the Milwaukee School of Engineering

The Energy Laboratory at MSOE serves undergraduate students in the Mechanical Engineering, Mechanical Engineering Technology, and Architectural Engineering programs. The Lab is a collaborative arrangement between MSOE and Johnson Controls, Inc., which operates a large HVAC system for training purposes.

The philosophy behind the continuing development of the Energy Lab is to allow the undergraduate students themselves to design and develop the equipment wherever possible. In this way, the Lab better fulfills its potential as a teaching facility. The primary vehicle for this work is the senior capstone design project. Several pieces of equipment have been designed in this way: a 140 ft/sec wind tunnel, a smoke tunnel for flow visualization, and most recently the psychrometric test chamber.

A team of two students was given the chamber design project. The stated purpose for the chamber was to demonstrate the basic psychrometric processes of heating, cooling, humidification, dehumidification, and mixing. A number of criteria were defined, and a cost target specified. The design report was used as the basis for construction of the chamber, and is on file at the school.
