The grains of moisture difference in the weather data tables are used for calculating:
A) The latent heat loss. B) The latent heat gain.
C) The cooling temperature difference. D) The sensible heat gain.
Question 2
Why should caution be exercised when replacing a low-efficiency air filter with a higher-efficiency air filter?
A) Higher-efficiency filters have a higher pressure drop, which can cause poor airflow.
B) Air-conditioning coils depend on a certain amount of small particulates to help moisture precipitate out of the air.
C) It is possible for air that is too clean to increase the occupant's sensitivity to allergens.
D) The lower pressure drop across high-efficiency filters can cause the blower motor to draw high amps.
