HVAC (Heating, Ventilation, and Air Conditioning) System Design

HVAC (Heating, Ventilation, and Air Conditioning) System Design is a specialized discipline within mechanical engineering that applies principles of thermodynamics, fluid mechanics, and heat transfer to create and maintain comfortable, safe, and energy-efficient indoor environments. The process involves calculating the heating and cooling loads of a building by analyzing its architecture, materials, climate, and occupancy. Based on these calculations, engineers select, size, and integrate a cohesive system of components—such as furnaces, chillers, air handlers, ductwork, and controls—to effectively regulate temperature, humidity, and air quality while adhering to building codes and energy conservation standards.
