One Person's Opinion: The Case For Tchebycheff (November 1999)
I am a mechanical design engineer that prepares hvac construction documents as plans and specifications for schools, office buildings, laboratories, etc. I have no interest in earning a living by the hvac test and balance (T&B) business, but then again, I never want the type of T&B that I have received in the past.
The purpose of this article is to prevent any further T&B reports that unknowingly state misleading and incorrect results that always jeopardize the hvac systems' ability to operate safely and as designed.
