Chapter hvac engineering Fundamentals: Part 1 Introduction

12.13
Summary
In building construction, HVAC design is interwoven with the electri-
cal design, and each discipline needs to be conversant with the other.
Electrical-mechanical interfaces need to be fully communicated for
complete designs to be achieved. The HVAC designer should have a
working background in the fundamentals of electricity and electric
control. Full presentation of the electrical needs of the HVAC system
must be part of the HVAC design work, as must a complete under-
standing of the impacts of electrical heat releases on the building en-
vironment.
