Introduction:

The field of Heating, Ventilation, and Air Conditioning (HVAC) is the science of controlling the indoor climate to provide healthy and comfortable indoor conditions. It involves adjusting temperature, humidity, air distribution, and noise levels in the indoor spaces of buildings.

The Engineering of Refrigeration and Air Conditioning Systems course aims to provide trainees with the fundamentals of air conditioning, refrigeration, and their applications. It covers the principles of thermodynamics, explaining the thermal phenomena and laws of fluids in both static and dynamic states. Additionally, it explores essential laws for calculating heat loads, determining the appropriate selection and design of air conditioning systems. Participants will gain knowledge of the history and evolution of air conditioning and refrigeration, understanding the physical properties of fluids in static and dynamic states, heat transfer methods, types and calculations of internal and external heat loads, psychrometric chart, its reading method, internal and external design conditions, factors affecting human comfort, and a study of the comfort zone map characteristics. The course also covers air properties, ventilation requirements, as well as the laws governing the calculation and selection of air conditioning and refrigeration systems, along with an introduction to measurement units in the international and British systems.
