Introducing the Psychrometric Chart – How we create the psychrometric chart from the thermodynamic properties of moist air tables and scale for the eight different properties.

Properties of Moist Air – The nature of air-water mixtures, indicators of moisture concentration in air, plus the 8 properties that we use in psychrometric analysis.Introduction to Psychrometrics – Understand the concept of temperature change, moisture change, enthalpy and the volumetric airflow equations and calculations.You will be tested at end of each section with Skill Development Exercises so you can truly feel confident about your progress and understanding of the presented material. You will also learn about s few of the special HVAC systems and the psychrometric analysis that is required to understand these systems, plus design suggestions these special systems. After completing the course, you should know how to: use a psychrometric chart properly design an HVAC system based on psychrometric principles conduct a psychrometric analysis of HVAC components such as air handling units, heating and cooling coils, humidifiers and de humidifiers evaluate the needs of individual spaces within a building and determine energy reduction opportunities for HVAC systems. You will develop an understanding of the basic concepts of psychrometrics including moist air properties, evaporation, enthalpy, and temperature change, plus the basic HVAC processes.
