Executive Designer Interview Questions and Answers

Designing a heat exchanger involves selecting appropriate materials, determining size and shape, and optimizing heat transfer efficiency.

• Consider the type of fluid being used and its temperature range

• Select materials that can withstand the operating conditions

• Determine the size and shape based on the required heat transfer rate

• Optimize the design for maximum heat transfer efficiency

• Consider factors such as pressure drop and fouling potential

Designing AC systems involves determining the cooling load, selecting appropriate equipment, and optimizing airflow.

• Calculate cooling load based on building size, orientation, insulation, and occupancy

• Select appropriate equipment such as air handlers, condensers, and ductwork

• Optimize airflow through proper duct design and placement of vents

• Consider energy efficiency and environmental impact when designing the system
