Generator Room Ventilation, Numerical Study, Industrial Application

Generator Room Ventilation,

Abstract Generator Room

In this project, the heating, ventilation, and Air Conditioning (HVAC) of a generator room are simulated using Ansys Fluent software. After completing the simulations, in which a generator room is initially simulated without a fan, it is observed that the room temperature with 32 generators is very high. 32 fans with 11,000 CFM are used, which decreases the Temperature considerably. But to improve ventilation and Temperature and obtain the desired thermal comfort between generator rows, 32 fans with 36,500 CFM have been added.

Purpose Generator Room

Generators are one of the most widely used and essential sources of Electricity in various industries. Generators generate much heat, affecting thermal comfort if several generators are together. Therefore, operators can not approach the generators in summer due to extreme heat. So to solve this problem, we used several fans to make the room temperature of the generator suitable for the operators.

Introduction Generator Room

In 1845, Michael Faraday, a prominent English physicist and chemist, showed that light and magnetic force are related and thus discovered Faraday’s work. Faraday’s discovery paved the way for the construction of the generator. About 50 years later, a German inventor named Carl Diesel revolutionized the electricity industry with the invention of the diesel engine. Diesel generator or diesel generator machine has been used for many years in all places, whether in hospitals or remote villages and in any place where access to Electricity from power plants is impossible.

Diesel generators generate emergency power and supply the necessary power continuously, either during peak consumption or even when the shortage of Electricity is felt. Ships and many large land vehicles, such as trains, also use diesel generators to provide lighting power and provide the propulsion they need. With electric propulsion, more constant and powerful movement can be done, and more appropriate use of space. Electric propulsion was used in ships before World War I and evolved during World War II. Power generation devices are classified and named in kilowatts based on average to maximum production capacity and based on generating power and are selected for continuous or emergency depending on the type of consumption.

A high-speed and robust industrial fan is one of the essential pieces of equipment in large industrial environments. Because despite the number of personnel, the presence of large devices, the entry of gases and pollutants, and other reasons, the oxygen in industrial environments is reduced. To increase the work efficiency of all departments, a high-speed industrial fan with high suction is needed.

An industrial fan or industrial ventilator is an important device in large work environments such as sheds, factories, greenhouses, industrial halls, clubs, large centers, etc. Since to increase work efficiency and better breathing, air circulation is needed to supply the required oxygen and create good air, the existence of devices that can rotate a large volume of trapped air and clean the air. A high-speed industrial fan device should be included in the agenda from this purchase.


A generator is a machine that converts mechanical energy into electrical energy through electromagnetic induction. A diesel generator is also a generator that uses diesel fuel to generate Electricity.

A diesel generator combines a diesel engine with an electric generator (often a dynamo) to generate electrical energy.

Diesel generators today have many applications in industry and even in everyday life. These motors are usually used in places with no access to Electricity. The primary purpose of diesel generators is to generate Electricity.

Diesel generators are usually produced and supplied in different dimensions for different applications. These dimensions are determined based on their apparent power. The generator used in this project is CAT C175-20 which has a power of 4000 kW.

Advantages of Diesel Generator

It is known that diesel generators require less maintenance than other generators on the market. Because the generator engine requires fewer components to start, you no longer have to worry about replacing spark plugs or rebuilding carburetors.

They are less sensitive to fuel and can use cheaper fuels such as diesel, oil, and fuel oil. Fuel should be one of the most important items for anyone buying a generator. Although diesel prices may be slightly higher than other fuel sources, these generators consume less than gas generators when doing the same job.

Diesel fuel storage is much safer than other fuel types, such as gasoline, which explodes quickly and catches fire easily if spilled. On the other hand, diesel has a much lower risk of ignition. It also lasts longer than gasoline to get better quality fuel from your stored source.

Increase life expectancy

Continuous power supply

When you experience a shutdown, an excellent and reliable diesel generator proves to work and your vital power systems for a long time. It minimizes downtime so that your facility does not experience significant financial losses while you wait for power to return.

Diesel generators can control larger loads and operate for longer than other existing generators. It makes them viable for remote sites where the power grid may be unreliable.

Disadvantages of Diesel Generators

Generator Room Result

This project aimed to provide suitable thermal comfort for the generator room. In the first simulation, when no fan was on, it was observed that the Temperature between the generators was more than 49 ° C. Therefore, it was decided to use a fan to reduce the Temperature. Thus, in the second simulation, 32 small fans are used, each with 11,000 CFM. We concluded that the room temperature is improved and reduced to 36 ° C. Then it was decided to use 64 fans (32 fans 11,000 CFM and 32 fans 13,500 CFM) to improve the thermal comfort of the generator room in the next simulation. The latest simulation results show that the airflow velocity inside the room has improved compared to the previous simulation, and the Temperature between the generators is equal to the outside Temperature (30 ° C).

    I found the study on the generator room ventilation fascinating! Can you elaborate on how symmetry was applied to reduce the computational cost? Also, what was the final distribution of Temperature across different parts of the generator room with all fans working?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Dear customer, we’re glad you found the study informative! For reduction in computational cost, symmetry allowed us to model only half of the actual physical space since the other half would behave identically, eliminating the need to calculate the entire space. Concerning the final Temperature distribution, once all fans were operational, airflow velocity was enhanced, creating a uniform temperature distribution equivalent to the ambient outside Temperature of 30 °C across the generator room.

    What does CFM stand for, and why is it significant for fans in the context of this simulation of the generator room?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      CFM stands for Cubic Feet per Minute, which is a measure of air volume flow rate. In the context of this simulation, CFM is significant because it indicates the efficiency of the fans in ventilating the generator room, ensuring the effective dispersal of heat generated by the generators and maintaining suitable thermal comfort.

    Great in-depth analysis on the generator room ventilation. The inclusion of both small and large-volume fans really demonstrates the improvement in air circulation and temperature control. Did the second simulation involving 32 fans at 11,000 CFM each also look at changes in humidity or just temperature?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The focus of the second simulation with the 32 fans at 11,000 CFM was primarily on improving the room temperature and ensuring effective air circulation for better thermal comfort. Changes in humidity were not specifically mentioned, but often, ventilation improvements can also help stabilize humidity levels indirectly.

    I’m curious about how the fans were specifically positioned and integrated into the simulation to reduce the temperature efficiently. It sounds like a complex scenario requiring precise distribution. How were the positions and angles for the fans determined?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this simulation, the 64 fans were carefully positioned to ensure efficient airflow through the generator room. The positions and angles were likely determined through preliminary tests and computational trials, optimizing air distribution to reduce hot spots and facilitate temperature homogeneity across the room. This is a standard practice in CFD analyses for HVAC systems, where both empirical data and simulation results guide the placement of ventilation equipment for optimal performance.

    The simulations provided insight into the ideal ventilation configuration needed for maintaining thermal comfort in the generator room. What evidence is there in the report to suggest that temperature reduction and improved airflow have a significant impact on the operational environment and safety?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The report demonstrates that without fans, the room temperature reaches above 49 °C which can lead to overheating and potential malfunctioning of generators or discomfort for operators. Adding fans lower the Temperature to safer, more comfortable levels, indicating enhanced operational safety and working conditions. Furthermore, the resulting Temperature after introducing fans is equal to the outside Temperature, confirming significant environmental improvement.
