Department of Architecture University of Florida Environmental Technology I ARC 3610 Morgan | Gold | Ogoli | Kim | Paek Spring, 2001 Homework Assignment 2 Psychrometry This homework provides students with an opportunity to investigate and understand the thermodynamic properties of moist air. It is due at the beginning of the lab on Thursday, January 25 th 2000. Psychrometry is the study of the properties of air. A psychrometric chart graphically describes the interactions between air, moisture, and heat energy. As air temperature rises, its ability to hold moisture rises; also warmer air becomes less dense. The part of the chart that describes the conditions at which most people are comfortable is called the comfort zone . The psychrometric chart, which may be used to graph a wide variety of processes, is actually a series of graphs superimposed on each other. They are described below. 1. Dry-bulb temperature lines are plotted vertically along the horizontal axis of the psychrometric chart. Dry-bulb temperature is a measure of sensible heat. Sensible heat is what is felt or sensed and is measured by a dry-bulb thermometer. Sensible heat is the kind of heat that increases the temperature of air; an open fire in the fireplace of a living
