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...
