Question 1

What does the acronym HVAC stand for in building systems?

Accepted Answer

Heating, Ventilation, and Air Conditioning

Answer

HVAC is the standard industry acronym for Heating, Ventilation, and Air Conditioning systems used to control building climate.

Question 2

Which HVAC system type controls room temperature by varying the volume of conditioned air supplied to each zone?

Accepted Answer

Variable Air Volume (VAV) system

Answer

VAV systems modulate airflow volume to each zone rather than temperature, allowing efficient, individualized comfort control.

Question 3

What is the primary function of a cooling tower in a commercial chilled-water HVAC system?

Accepted Answer

To reject condenser heat from the refrigeration cycle to the atmosphere

Answer

Cooling towers dissipate heat removed by chillers by evaporating condenser water, completing the refrigeration cycle.

Question 4

What term describes the natural vertical air movement caused by temperature differences between indoor warm air and cooler outdoor air that can drive passive ventilation?

Accepted Answer

Stack effect

Answer

The stack effect occurs when buoyant warm indoor air rises and exits at upper openings, drawing cooler outdoor air in at lower openings.

Question 5

Which type of ventilation system both supplies fresh air and exhausts stale air in equal quantities to maintain indoor air quality without creating pressure imbalances?

Accepted Answer

Balanced ventilation

Answer

Balanced ventilation systems manage both supply and exhaust airflows equally, preventing pressure imbalances and ensuring consistent fresh air delivery.
