HVAC, ANSYS Fluent Training Package for Beginners

HVAC ANSYS Fluent Training Package, 10 Practical Exercises for BEGINNER Users

Heating, ventilation, and air conditioning are the technology of internal and vehicular environmental relief. It aims to prepare thermal comfort and tolerable Indoor Air Quality (IAQ). HVAC system modeling is a mechanical engineering subfield based on thermodynamics, fluid mechanics, and heat transfer.

In the HVAC System design, you may meet considerable technological problems that affect your CFD simulations. Whether you model perfect HVAC systems or the generation of HVAC ingredients, computational fluid dynamics (CFD) software from ANSYS Fluent can support you in outreach your technical challenges.

This CFD Training Package helps you to overcome the following issue:

• Indoor Air Quality (IAQ)
• Energy Efficiency
• Minimize System Cost
• Reduce Design Time and Expense
• Understand and Diagnose Problems
• Improve Performance

This package includes 10 different practical exercises in the HVAC field by ANSYS Fluent software for BEGINNER users.

Practical exercise number 1 simulates the airflow around the outer body of swamp coolers as cross ventilation. The function of water cooler systems is such that the outside warm air is sucked into their building and meets the pumped water flows in the cooler. The water flow receives the latent heat it needs to evaporate from the perceptible heat of the incoming airflow, and as a result, it evaporates. In project number 2, the movement of the cooling airflow inside a room applying a swamp cooler is investigated. The air inside the room is cooled using a swamp cooler and is distributed inside the room space. The standard k-epsilon model is exploited to solve turbulent flow equations, and the Energy equation is activated to calculate the temperature distribution inside the computational domain. Problem number 3 simulates the heat transfer from a floor heating system into a room. In fact, this heating system is built into the floor of the room, which acts as a heat source. It is assumed that this heating system has a constant thermal flux of 166.6 W.m-2.

In practical exercise number 4, the heat transfer of an underfloor heating system in an enclosed space was simulated and analyzed by ANSYS Fluent. It is assumed that the underfloor heating system generated heat flux is assigned to the bottom wall (other walls are considered to be adiabatic). Since in this analysis, an underfloor heating system is used to generate heat, no fluid flow inlet is used in this project, and only a pressure outlet is defined.  Problem number 5 simulates the airflow inside a room and the process of air conditioning. There are three sections for the entry of fresh air on the roof of the room; So that the airflow enters the interior of the room with a speed equal to 0.4 m.s-1 and at a temperature equal to 295 K.  In project number 6, steady airflow in a storage container room with two walls is investigated. Container rooms are often used for the storage of industrial goods which are perishable and are required to be kept under influence of steady airflow for purpose of cooling and ventilation. In the present work, steady airflow is simulated in a 0.5 * 0.5 * 1 room with two walls against the airflow path, which represents containing chamber.

In practical exercise number 7, steady airflow over a ventilated air cavity is investigated. The simulated cavity has a hole that extends in flow direction all over the cavity length and makes the simulation more challenging. Fluid flow over objects is of great importance since the results are useful in several branches of fluid mechanics, such as aerodynamics.  To increase efficiency and reduce the risks of temperature rise in server rooms, the safe range offered by manufacturers is in the range of 10 to 32 degrees. Thus, decreasing the temperature below 10 degrees and increasing the temperature above 32 degrees creates unstable conditions in terms of thermal comfort in these rooms. Therefore, the airflow inside the server room was modeled using Ansys Fluent in practical exercise number 8. Problem number 9 simulates the process of heat transfer through the underfloor heating system by the spiral pipe. In this project, a room is designed for cold winter conditions, and a floor heating system is installed to heat the air inside the room. The underfloor heating system is in the form of a spiral tube that carries the flow of hot water.

Finally, practical exercise number 10 is to simulate the airflow and ventilation inside a windcatcher as the last product of this package for Intermediate users. The windcatcher is octagonal and has a relatively simple structure. The windcatcher consists of a column for pulling the out air to the inside or sucking up the air inside, room space for air circulation inside it, and a wall for the space around the building of this windcatcher, and also this windcatcher set is located in a large space of open airflow domain.
