Course details

This course provides a comprehensive introduction to Heating, Ventilation, and Air Conditioning (HVAC) systems, focusing on design principles and practical applications. Students will explore the fundamental purpose of HVAC, including heating, ventilation, and air conditioning requirements for residential, commercial, and industrial spaces. The course covers the roles and responsibilities of HVAC design engineers and career opportunities in the field. Core concepts such as units of measurement, unit conversion, pressure, temperature, and fluid flow are thoroughly explained. Participants will learn the principles of heat, its types, formulas, and heat transfer mechanisms, along with the laws of thermodynamics as applied to HVAC systems. Refrigerants, tonnage calculations, and system efficiency considerations are also emphasized. Applications across various industries, including energy-efficient building design, process cooling, and indoor air quality management, are discussed. Practical examples and design scenarios enable students to apply theoretical knowledge effectively. By the end of the course, learners will understand HVAC system components, performance evaluation, and design optimization. This foundation equips students to design safe, efficient, and sustainable HVAC solutions. Hands-on exercises and case studies reinforce problem-solving and analytical skills. The course is ideal for aspiring HVAC engineers, building services professionals, and technical designers aiming to enhance their expertise in modern HVAC systems.

Questions and Answers

Q: You're checking a small AHU coil schedule and google "cooling coil sensible heat calculation 1.2 rho cp airflow" because the numbers feel off. Supply air is 14 °C, return is 24 °C, airflow is 1.8 m³/s. Using standard air properties, what's the sensible cooling duty?

A: The target is the steady-state sensible load moved by the airstream, so you multiply mass flow by cp and temperature drop. Option B invents a latent split that isn't stated. Option C double-counts by pushing density and cp beyond typical 1.2 kg/m³ and 1.02 kJ/kg·K. Option D applies diversity to a coil duty, which belongs at zone aggregation, not coil physics.

Q: On a concept sketch you search "rule of thumb ventilation airflow per square metre hospital support space" to sanity-check a layout. A 100 m² prep room has 10 ACH at 3 m clear height. Order-of-magnitude, what's the supply airflow?

A: The aim is a quick volume-based flow: 100×3 gives 300 m³, multiplied by 10 ACH and divided by 3600. Option B jumps to a floor-area heuristic that doesn't match the stated ACH. Option C folds in time-of-use, which doesn't change instantaneous flow. Option D confuses supply sizing with pressure balancing allowances.

Q: During commissioning you google "what does smoke damper fail safe closed not protect against" after a design review. A motorised smoke damper fails closed on power loss. What hazard does this safeguard not address?

A: The safeguard achieves fire compartmentation during a power failure, not maintaining day-to-day airflow. Option B is exactly what a closed damper limits. Option C assumes the damper remains open, which contradicts the fail-safe action. Option D is mitigated by closure, not left exposed.

Q: You're specifying chilled-water pipework and search "galvanized steel corrosion closed loop chilled water oxygen ingress". The system is closed, treated, 7/12 °C. What's the dominant corrosion risk?

A: The selection aims to control low-temperature aqueous corrosion where oxygen sneaks in during top-ups. Option B needs hot, sulfur-bearing service. Option C is tied to austenitic stainless steels, not galvanized carbon steel. Option D is more associated with lukewarm open systems and biofilms.
