An important memo from the author.
I was once had a chance to learn about the fundamentals of chilled water system from a reputable HVAC expert. We talk casually and he taught me a lot about how the system actually works and shared with me why many engineers misunderstood the system. From there, I did further research and put together this ebook to help other engineers to learn the true principle lies behind the chilled water system.
“Reason from first principle and seek for the fundamental truth in order to truly master a subject.”
