What do you think are the most important things to know about ductwork design?

There are many factors that go into ductwork design in order to create an efficient and effective HVAC system. The interviewer is likely asking this question to gauge the candidate's knowledge and understanding of the various aspects of ductwork design. In order to properly answer this question, the candidate should be familiar with topics such as air flow, pressure drop, duct sizing, and routing. Additionally, the candidate should be able to explain why these factors are important in designing an effective HVAC system.

Example: “There are several important factors to consider when designing ductwork for HVAC systems, including:

1. Airflow: The amount of airflow required for a space depends on a number of factors, including the size of the space, the number of people using it, the type of activities being conducted, and the climate. When designing ductwork, it is important to ensure that the system will be able to provide the correct amount of airflow.

2. Static pressure: This is the pressure difference between the inside and outside of the ductwork. It is important to consider static pressure when designing ductwork, as it can affect how well the system works.

3. Velocity: The velocity of air flowing through the ductwork can also affect its performance. If the velocity is too high, it can cause noise and vibration, and if it is too low, it can result in poor airflow.

4. Materials: The type of material used for ductwork can also impact its performance. For example, metal ductwork is more durable than plastic ductwork but is also more expensive.

5. Installation: The way in which ductwork is installed can also affect its performance. Poorly installed ductwork can result in leaks and drafts,”

What do you think are the most important things to know about ductwork installation?

There are a few reasons why an interviewer might ask this question to an HVAC design engineer. One reason is to gauge the engineer's understanding of the installation process.
