HVAC helps keep people comfortable and healthy by maintaining good indoor air quality, humidity and comfortable temperatures. Designing for comfort requires integrated knowledge of human physiology, heat transfer, psychrometrics, and mechanical systems. Most professionals don't learn this stuff in school or on the jobsite, but are expected unrealistically to meet your physiological needs and wants for indoor environmental quality based predominantly on the skills of assembling building components. This is the #1 reason why over 50% of occupants are unsatisfied with their thermal environments. This 6-hour course provides the basic concepts of human comfort, temperature - humidity relationships, the principles of psychrometrics and modes of heat transfer you need to design new HVAC systems and/or to retrofit existing systems. It also covers the methodology of heat loss/heat gain calculations and the concepts of noise and acoustic treatment. The second part of this course "HVAC Components and Systems" is separately listed. This quick book will focus on the HVAC heating and cooling equipment's, air and hydronic distribution and the various types of HVAC systems. This course is applicable to mechanical engineers, architects, energy auditors, facility managers, operation and maintenance personal and others in the design and renovation of facilities. The course is relevant to anyone needing to know more about HVAC fundamentals and processes. Basic knowledge of thermodynamics, fluid flow desired. The reader must take a multiple-choice quiz consisting of thirty (30) questions at the end of this course.
