What type of air-conditioning system maintains air quality and lessens contaminants?
  1. Open-loop
  2. Closed-loop
  3. Both A and B
  4. Neither A nor B
Explanation
Answer: B - Closed-loop air-conditioning systems maintain air quality and lessen contaminants. Closed-loop means the air within the building is reused after it has been proper filtered, instead of bringing outside air in. Positive pressurization and ventilation should be used in addition to closed-loop systems to further control contamination. Positive pressurization allows air to go out while preventing outside air from coming when a door is opened.
