2 cards from this section. Quick, good the night before a test.
Define the Humidity Ratio.
Think about the measurement units for water and dry air.
What does RH stand for?
Consider what you measure in relation to saturation.
What measurement does Humidity Ratio (HR) express?
Think about how it's measured.
True or False: An increase in HR generally improves comfort in summer.
Consider what humidity does to our perception of temperature.
You have an air conditioning system that currently has an HR of 0.012 kg/kg. Describe how you would adjust the system to lower the HR to enhance feel in a summer setting while minimizing energy usage.
Consider both temperature adjustments and moisture extraction techniques.
Calculate the change in enthalpy if HR increases from 0.005 kg/kg to 0.015 kg/kg at a constant temperature of 25°C. What implications does this have on the cooling load?
Examine the role of moisture in enthalpy through HVAC performance metrics.
