Load & Design第 20 / 110 题
Latent load in a cooling calculation refers to the energy required to do what?
a.Raise the dry-bulb temperature of the air
b.Remove moisture (water vapor) from the air
c.Overcome duct friction
d.Power the compressor motor
解析
Latent load is the heat associated with condensing water vapor out of the air, lowering humidity. Sensible load changes air temperature, while latent load changes moisture content. Both must be met for comfort, especially in humid climates.
