This Video Lecture contains Introduction to Psychrometry, Properties of Air. It also introduces Psychometric chart.
This video lecture covers the definition, Classification of Air Conditioning System.
Note: This video is a recording of a online lecture series hence the video is interrupted in between. Please follow the next two lectures on Air Conditioning System part 2 & Part 3 to maintain the continuity.
Classification of AC systems. Representation of Ac system processes seasonally on Psychrometry chart
This Video lecture covers concept of the Sensible Heat factor, RSHF, GSHF & ESHF. Also Numerical on basic load calculation using psychrometric chart.
This video lecture explains the Air Conditioning system design Numerical: RSHF- Room Sensible Heat Factor line plotting on psychrometric chart and load calculation.
This course is helpful to Undergraduate Mechanical Engineering Students as well as Practicing HVAC Engineers for :
Understand and calculation of properties of air
Air Conditioning system types and
Sizing of Air Conditioner.
The course is designed for beginners to start with the basics of Psychrometry then actual air conditioning systems are explained. At the end of the course students will be able to design and size the air conditioner required for their specific application.
For practicing HVAC engineers this course will refresh their basic concepts and will help to precisely size the AC instead of thumb rule based practice.
Content:
