5 Simulation Projects for Heating, Ventilation, and Air Conditioning (HVAC)
HVAC systems are essential for a wide range of applications, from thermal comfort in office spaces and automobiles, to data center ventilation.
Simulation provides a method for engineers and HVAC specialists to design, analyze, and optimize these systems.
Let’s take a look at some examples available in the SimScale Public Projects library:
A natural convective heat transfer analysis was performed assuming fixed temperatures at the walls and air conditioning inlet. Other boundary conditions could, however, be applied, such as heat loss at windows or adiabatic walls. The room temperature and airflow throughout the room were determined.
A passive scalar transport analysis was done to show how gas enters a room via the climate system. The results show the concentrations of the gas as it spreads throughout the room.
A natural convective heat transfer analysis was done to determine the airflow velocity and temperature fields of a server room. Based on the results, the room layout and positioning of the ventilation and air conditioning units can be optimized for better performance and energy savings.
For this simulation, a steady-state natural convective heat transfer analysis was done. The indoor part of the hall, as well as the outdoor environment, was modeled with fixed temperature and zero-gradient boundary conditions assigned, assuming a cold weather condition. Results include pressure and velocity fields, volume flux, and final temperature in the hallway.
A steady-state natural convective heat transfer analysis was done to simulate internal airflow in a car cabin. The cabin has a 4-inlet air conditioning system located in the front dashboard and an outlet vent on the hood. The initial car temperature was 30 degrees Celsius and the temperature of the airflow was set at 10 degrees Celsius. The final results demonstrated the airflow velocity through the cabin and the rate of cooling in the vehicle.
The projects described above can be imported into your own workspace for free, to help you start your own simulation with minimum effort. If you have any questions regarding the platform or simulation in general, the SimScale Forum and the workshops are the perfect places to ask them. See you there!
