HVAC ANSYS Fluent Training Package, 10 Practical Exercises for EXPERT Users
This training package includes 10 various practical exercises in the HVAC field by ANSYS Fluent software for EXPERT users.
We start this training package with practical exercise number 1, which simulates the ventilation, air circulation, and solar radiation heat transfer in an office. The heat is emitted by people, objects, and electrical equipment inside the room. A man, a computer, and two lamps are modeled inside the room. In project number 3, radiation heat transfer inside a room with a balcony is investigated. The balcony has a glass roof and one glass wall. Due to the radiation of sunlight, both room and balcony become warmer and natural convection plays an important role in circulating the flow inside these spaces.
Problem number 6 simulates the radiation of solar rays into the room’s interior considering the effects of a wooden partition as solar shading, and a double glazing glass offaçade. Argon gas has accumulated in the space between the two glasses of the double glazing. Because argon gas has low thermal conductivity. Practical exercise number 8 simulates the process of air conditioning in an office with several computers and simulators. The air conditioning system in the current model is of floor heating and ceiling cooling. In this way, the effect of buoyancy causes free heat transfer inside the computer room space.
In project number 2, based on the CFD method, an attempt has been made to simulate the respiration of viral air from the mouth of sick coronavirus carrier students in the classroom. This model includes a computational domain in the form of a classroom and chairs inside which a student is modeled on each of the chairs. For each of these students, a surface is defined as the mouth as the source of the virus’s respiration and transmission. In practical exercise number 7, three different HVAC models were analyzed to compare the effect of different types of ventilation inside a room. A corona patient breathes on the breathing particles coming out from the patient’s mouth and how they spread inside this room. These types of HVAC include one-sided (single-sided), cross-sided, and lateral ventilation.
Problem number 4 simulates the air conditioning inside a transformer room where three transformers are located. In this project, a two-piece room is designed with a divider in the middle, made by a wooden wall with thermal conductivity of 0.173 W.m-1.K-1. Inside the room, there are three transformers made of aluminum with thermal conductivity of 202.4 W.m-1.K-1, each of which has a constant heat source equal to 6060.606 W.m-3.
Phase Change Material (PCM)
Practical exercise number 5 simulates phase change material (PCM) for a room passive air conditioning. In general, phase change materials are materials with organic compounds that can absorb and store large amounts of latent thermal energy. Thermal energy storage in these materials is achieved during the phase change process (solid phase to liquid or vice versa).
Problem number 9 simulates the air conditioning inside the car park. In this project, a stacker parking is designed, with three floors and two cars located on two floors. The structure of this type of parking lot is such that there are moving platforms on which the cars are placed, and then these platforms with the car are lifted vertically up between the two columns and placed at a higher height so that the space under it, to provide the next car park on the lower platform.
Paper Validation (HVAC)
Finally, practical exercise number 10 simulates the HVAC process through a side supply air conditioning system in an office. This simulation is based on the information of a reference article [Comparison of air-conditioning systems with bottom-supply and side-supply modes in a typical office room] and its results are compared and validated with the results in the paper. The simulation is performed for a state of the paper where the side-supply air conditioning system is designed.
