Participation reward: 2 Wealth. Reward for correct answer: 9 wealth. Which of the following statements about all-air variable air volume air conditioning systems is correct? ( ) A. The lower the air volume, the less energy is consumed; therefore, there should be no restrictions on the minimum air volume for such systems. B. Since the air volume in variable air volume air conditioning systems is reduced, indoor noise is usually lower. C. The amount of fresh air supplied to each room in a variable air volume air conditioning system cannot be adjusted independently. D. Because the air supply volume in variable air volume air conditioning systems can be controlled independently, it is not necessary to separate the interior and exterior areas.
