Course Title: HVAC Fundamentals: Psychrometrics and Processes
Delivery Method: Live Online
Course Description: This three-hour course explores the fundamentals of HVAC psychrometrics and processes, focusing on air-water vapor mixtures and their impact on heating, cooling, and air conditioning design. The course will demonstrate how to calculate key properties such as humidity ratio, relative humidity, dew point, and enthalpy, as well as the utilization of psychrometric charts. The course also covers HVAC processes and considers the effects sensible and latent heat loads have on HVAC design.
Learning Objectives:
Learning Objective 1: Learners will be able to calculate key psychrometric properties of air-water vapor mixtures, including humidity ratio, relative humidity, dew point, and enthalpy.
Learning Objective 2: Learners will be able to utilize psychrometric charts to analyze air-water vapor mixtures and HVAC system performance.
Learning Objective 3: Learners will be able to analyze and describe HVAC processes such as heating, cooling, humidification, dehumidification, and air mixing.
Learning Objective 4: Learners will be able to assess sensible and latent heat loads and their role in HVAC system design.
