HVAC stands for heating, ventilating, and air conditioning, and it is one of the most important aspects of mechanical engineering. As a mechanical engineer, you are in an advantageous position because there are no other engineering branches that exclusively focus on HVAC or are directly related to it.

If you choose to study mechanical engineering, you will come across the term HVAC since it is directly related to fluid dynamics, thermodynamics, and heat transfer, which are the cornerstones of mechanical engineering.

To excel in the HVAC industry, you need to have a good understanding of these subjects. You will likely be involved in the development and production of air conditioning systems for various applications, such as automotive, industrial ventilating, and air conditioning systems, among others. There are many renowned companies in this field, such as Mitsubishi Electric and Daikin.


Also, the competition in the HVAC industry is not as high as in aerospace and automotive. This is because HVAC is a highly technical and detailed section of mechanical engineering.

In the HVAC industry, you can find yourself creating and developing fridge systems or deep freezing systems. So, if you take part in the HVAC industry, you can find yourself dealing with the substructures or subsystems of these air conditioning systems.

Defense Industry

The defense industry is closely related to the aerospace industry. This industry involves the manufacturing and design of various systems, such as fighter jets or unmanned vehicles. As a mechanical engineer, you can take part in designing the mechanical and electrical systems of these defense industry vehicles or systems.

In the defense industry, the manufacturing and design of ammunition or arms are also common. You can find yourself designing different systems, such as internal mechanical structures of arms or the landing gear systems of fighter jets, among others.

To enter the defense industry, it is important to graduate from reputable universities in your country. The income rates and responsibilities are high in the defense industry, and a good GPA from a reputable university is often required.

Mechanical Vibrations and Acoustics

Vibrations.

This is another highly technical aspect of mechanical engineering. You will focus on improving the vibrational characteristics of mechanical systems, such as reducing the vibrational effects of internal combustion engines on vehicles.

Acoustics is also important and directly related to the theoretical side of mechanical engineering. In many cases, noise levels need to be minimized in daily-use products. Take washing machines, for example. Washing machines create noise in your house, but as an engineer, your task would be to minimize that sound as much as possible. To achieve this, you need knowledge of the theoretical aspects of acoustics, which is a part of mechanical engineering, and apply sound control techniques to bring it to an acceptable level.

Classical Mechanics

This is also a fundamental branch of mechanical engineering. It encompasses dynamics, statistics, and the strength of materials, along with topics generally related to these areas. Materials and material information play a crucial role in classical mechanics.

Classical mechanics primarily focuses on the theoretical side of mechanical engineering. For example, you will deal with fatigue calculations of mechanical or engineering systems, as well as fracture calculations of various systems.

If you are inclined towards creating software programs or enjoy controlling hardware using different software systems, you can choose control engineering as a specialization while studying mechanical engineering.

You are creating control systems for various applications. Let’s consider an example: a diesel engine with a mass air flow sensor. The mass air flow sensor measures the airflow coming from the vehicle’s intake manifold and sends this information to the ECU (Engine Control Unit) system. The software inside the ECU determines the optimal fuel rate to send to the intake manifold.

A control engineer with expertise in the automotive industry develops software systems like this within the ECU. They have knowledge of the hardware components such as sensors, cables, and electronic systems. They must possess a deep understanding of software programming and how to manipulate parameters to create an optimal control system.

In recent decades, control engineering has become a distinct branch of engineering that you can directly specialize in. If you are studying mechanical engineering and prefer to focus solely on control systems, you can choose a control engineering specialization.

Quality Assurance and Control

Quality assurance involves ensuring that designed or manufactured systems comply with various standards. For instance, if you manufacture a household object and plan to sell it in Europe, there are strict standards and regulations to adhere to. A quality assurance engineer assesses the product’s compliance with these regulations.

Quality assurance and control engineers possess knowledge of technical drawings, including how to read and create them according to the standards.

Some may consider this branch of mechanical engineering to be boring, but it is far from it. Quality assurance and control engineers are constantly in contact with other individuals and engineers, ensuring that everyone follows the defined regulations and standards.
