Description

Hello! Welcome to the one of the highest rated HVAC course in Udemy! If you are starting out in the HVAC industry, or wished to gain more knowledge in an area which seems complicated and confusing to most people, you have found the right course!

My strength and approach in training is simplifying the important knowledge into something you will be able to grasp easily. In this course, I cover the air side in building air conditioning systems extensively, and will build your knowledge slowly until you reach the competency of evaluating, selecting and sizing Air Handling Units (AHU) and Air Ducts.

Applying mechanical engineering theoretical concept such as thermodynamics, heat transfer, fluid mechanics, you will translate these theories into valuable and applicable knowledge specific to HVAC industry. They include psychrometry, equal friction method for duct sizing, analyzing heat gain in space and even controls application using BMS!

Join me to give yourself a head start in the HVAC career!


Learning Outcomes and Content

1) Introduction to Air Handling Systems

  • Explain the working principle of air handling and fan coil unit

  • Explain the controls for pressure dependent and pressure independent VAV

  • Interpret duct drawings and BMS graphics for air-side

2) Space Cooling Load

  • Describe the three mechanisms of heat transfer

  • Identify the heat gains in a building

  • Estimate the cooling loads of a building

3) Psychrometry

  • Define the thermo-physical properties of air

  • Analysis of various air treatment processes by applying the psychrometric chart

  • Explain air conditioning processes in the building

4) AHU and Duct Selection

  • Define the components of pressure loss in an air distribution system

  • Explain the use of the equal friction method on the sizing of air distribution duct work

  • Apply the procedure for determining pressure losses in air distribution duct work


⭐⭐⭐⭐⭐Some 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.

Hello! I graduated with a masters in mechanical engineering and I started off my career as a Heating Ventilation and Air-Conditioning engineer.

As a HVAC engineer, my job is to do the design and equipment selection for the water side and air side of the air conditioning system, such as chillers, cooling towers, pumps and piping. The air side includes air handling unit, fan coil unit and ducting system.

After years of experience and passing my PE exam, I decided to move on to a BMS company as an application engineer. It is one of the best decision I have made in my career life as I got to learn so much about the trade through this role, which I have never thought of as a HVAC designer.

And now, I provide consultancy services and training workshops to building owners and facility managers. I equip them with the knowledge on how to reduce their building energy consumption significantly through the air conditioning system. With my new found passion in teaching, knowledge sharing and online course creation, I hope to reach out to more people who are interested in my area of expertise globally!
