Description

This course provides an introduction to HVAC systems including a deep dive on core key topics of thermal comfort, indoor air quality, ventilation rate standards, contaminants, healthy buildings, system types, air-side and thermal-side equipment, chillers, refrigeration cycles and Psychrometrics. This knowledge provides a solid foundation of understanding HVAC systems and ensures an ideal knowledge base from which to move onto deeper learning of design methods & techniques. The course is ideal for those wishing to upskill for moving into the much in demand HVAC industry and those aiming to transition into this area. As it starts from fundamentals it is also beneficial for current students, technicians and practitioners. Generally the course is designed for beginner to intermediate level e.g., from beginner up to 2nd or 3rd year Bachelor degree level.The content is generally presented in SI metric units but where appropriate the related IP imperial units are also provided. Relevant HVAC standards and codes are noted, particularly international standards and codes that are adopted in many countries around the world. The content also covers issues related to sustainability, e.g. the implications of thermal comfort and indoor air quality on occupants health and well being; the atmospheric impacts of a wide range of refrigerants used in chillers.It includes a self-assessment quiz and completion certificate which can be valuable evidence for career development. Students can start-stop-rewind-fast forward lecture sessions at any time making it easy to keep your place, retrace your steps or review your understanding in your learning journey.The course has been developed by an experienced academic who has designed, managed and delivered undergraduate Bachelor and postgraduate Masters programs in Architectural Engineering, Building Services Engineering and Architecture between Ireland, United Kingdom and United Arab Emirates with students from India, Malaysia, Philippines, Saudi Arabia, Egypt, Iran, Jordan, UAE, Ireland, Scotland, Germany, Wales & England.
