## 9.1. HVAC Simulations

HVAC studies range in scale from single components (such as a radiator) to large and complicated systems (such as a climate control system for a large building).

Physical processes that are commonly modeled in HVAC simulations include:

- Buoyancy

- Thermal radiation

- Conjugate heat transfer (CHT) between fluids and solids.

Typical HVAC systems include the following components:

- Heating/cooling units such as furnaces, heaters, air conditioners, and radiators

- Fans/pumps

- Thermostats.
