HVAC Psychrometry Air Handling System and Duct Selection


Some engineering or field knowledge in HVAC is preferable but not mandatory. All the concepts are explained in depth using an easy to understand language to allow students to build their knowledge from the ground up


Welcome to one of Udemy’s top-rated HVAC courses! If you’re new to the HVAC industry or looking to expand your knowledge in a complex and often perplexing field, you’ve come to the right place.My training approach focuses on simplifying critical concepts so that they’re easy to grasp. In this course, I delve extensively into building air conditioning systems’ air side, guiding you step-by-step to competency in evaluating, selecting, and sizing Air Handling Units (AHU) and Air Ducts.By applying fundamental mechanical engineering concepts such as thermodynamics, heat transfer, and fluid mechanics, you’ll learn how to translate theories into practical knowledge applicable to the HVAC industry. Topics covered include psychrometry, equal friction method for duct sizing, analyzing heat gain in space, and even control applications using BMS!Enroll in this course to gain a head start in your HVAC career!Learning Outcomes and Content1) Introduction to Air Handling SystemsExplain the working principle of air handling and fan coil unitExplain the controls for pressure dependent and pressure independent VAVInterpret duct drawings and BMS graphics for air-side2) Space Cooling LoadDescribe the three mechanisms of heat transfer Identify the heat gains in a buildingEstimate the cooling loads of a building3) PsychrometryDefine the thermo-physical properties of airAnalysis of various air treatment processes by applying the psychrometric chartExplain air conditioning processes in the building4) AHU and Duct SelectionDefine the components of pressure loss in an air distribution systemExplain the use of the equal friction method on the sizing of air distribution duct workApply the procedure for determining pressure losses in air distribution duct workSome 5 stars reviews from the students:Once again, I take the course about HVAC at mike academy. This course is a really good, detailed explanation, and it’s easy to understand.It’s an excellent course, and I really enjoyed the course. The concepts are detailed and clearly explained so that I could get a lot of valuable information. Very Good Job, Mike!This course is great! It goes in depth for understanding how to use psychrometry and what it means in a real life system. Learning a lot!Great course overall! As a HVAC Operations Engineer in the Pharmaceutical Industry, this course was a really good refresher for some basic but really important aspects and content of the HVAC Industry. Thanks Mike!Excellent course. All important concepts in related to the topic are presented in a manner it is easier to understand. Highly recommended course for building operation and maintenance professionals and techs.
