Key concepts in HVAC

 Here are some key concepts in HVAC (Heating, Ventilation, and Air Conditioning): 1. Thermodynamics:  Study of heat transfer, energy, and work. 2. Psychrometrics:   Study of air properties, humidity, and moisture. 3. Airflow and Pressure Drop:   Understanding airflow rates, pressure losses, and duct sizing. 4. Refrigeration Cycle:   The process of heat transfer and cooling in refrigeration systems. 5. Heating and Cooling Loads:  Calculating building heat gain and loss for HVAC system design. 6. Zoning and Control Systems:   Dividing buildings into temperature zones and controlling HVAC systems. 7. Indoor Air Quality (IAQ):  Maintaining healthy indoor air through ventilation, filtration, and air cleaning. 8. Energy Efficiency and Savings:  Optimizing HVAC system performance to reduce energy consumption. 9. HVAC System Design and Selection: Choosing the right HVAC system for building type, size, and application. 10. Installation, Maintenance, a...
