What is HVAC Engineering and Design?
HVAC stands for heating, ventilation, and air conditioning. It is one of the popular terms in mechanical engineering. The goal of HVAC engineering and design technology is to provide thermal comfort and good indoor air quality. The technology is highly based on the principles of thermodynamics, heat transfer, and fluid mechanics.
HVAC is an essential part of residential as well as commercial buildings. HVAC engineering and design can be put to use in single-family houses, hotels, apartment buildings, medium or large industries, skyscrapers, hospitals, and many more. HVAC is not only restricted to buildings and houses, but it can also be implemented in vehicles such as cars, airplanes, submarines, and other marine vehicles.
One of the most important aspects of HVAC engineering and design is ventilation. The ventilation system used in HVAC continuously replaces the inside air with the fresh outside air. It also involves temperature control, removal of moisture, smoke, odors, heat, carbon dioxide, and other gases. Ventilation keeps the interior building air circulation and prevents stagnation of the air inside.
What is Breaker Coordination?
Once the building has been constructed, the next important factor is the electrical fitting of the building. Electrical systems in a building commonly make use of fuses and circuit breakers to protect the electrical equipment. A circuit breaker coordination study is one to analyze the tripping times for a series of overload or overcurrent devices being compared.
The circuit breaker coordination study optimizes the selectivity of different devices. Selectivity means isolation of a faulty circuit such that the fault in one circuit does not affect other protective devices in the system. A proper study can lead to help in minimizing the negative impact of device failures.
Just imagine fault in a single motor resulting in shutting down your entire building's electrical facility? You definitely don't want that to happen! Therefore, a protective device coordination study is essential to prevent this kind of problem from occurring.
There are two types of standard circuit breakers, which are - single pole breakers and double pole breakers. Single pole circuit breakers protect one energized wire, supplies 120V to a circuit, and can handle 12-20 amps of current. On the other hand, double pole circuit breakers have a handle and a commonly shared trip mechanism. It can protect two energized wires, supply 120V to 240V to a circuit, and can handle 12-200 amps of current. The double pole breakers are used for large appliances like water heaters.
What is Power System Study?
When a building is made, it is expected to have the best power system facilities. For that, an electrical power system analysis of the building is needed. Power system studies consist of different engineering analysis investigations and findings.
A power system comprises of generation, transmission, and distribution. Power system studies are essential for finding out whether the building's power system is a reliable one or not. To avoid power failures, short circuits, or fault current, you will have to do a power systems study. The significant benefits of power systems review are a robust performance and maximized plant availability for all operating conditions, which will include transient conditions like motor starting, generator loss, and non-linear loads.
To study power systems, various software programs are available. Different companies use different software according to their need, budget, usage, and set criteria.
