Introduction: HVAC System Fundamentals

Understanding the components and operation of heating, ventilation, and air conditioning systems

HVAC systems are the heart of building climate control, responsible for maintaining thermal comfort while consuming significant energy. Understanding how these systems work is crucial for optimizing efficiency and reducing carbon emissions.

Modern HVAC systems combine heating, ventilation, and air conditioning through complex interactions between mechanical components, electrical controls, and thermodynamic processes. Each component plays a critical role in system performance and efficiency.

What happens: Fresh air enters → gets filtered → blower pushes it → heat exchanger conditions it → flows through ducts to your home

Why HVAC Efficiency Matters

🏢 Building Energy Use

HVAC systems account for 40-60% of total building energy consumption

💰 Cost Savings

Efficient systems can reduce energy costs by 20-50%

🌱 Carbon Reduction

Better efficiency directly reduces greenhouse gas emissions
