🔍 Key Concepts

• Liquid desiccant dehumidification cycle – how the desiccant picks up moisture, then how it is dried again • Difference between evaporation and condensation in HVAC/refrigeration processes • Role of heating coils vs. cooling coils in changing the state of water

💭 Think About

• When a desiccant is "regenerated," is the system trying to add more water to it or remove water from it? How is that usually done in drying systems? • Does heating generally cause water to evaporate or condense? What about cooling? Apply that to the water inside the desiccant. • In a regeneration chamber, what is the main purpose: to concentrate (dry out) the desiccant or to dilute it? Which coil action (heating or cooling) best supports that purpose?

✅ Before You Answer

• Be clear on what regeneration means: the desiccant should come out of that chamber drier, not wetter. • Match the correct change of state of water (evaporation vs. condensation) with the correct type of coil (heating vs. cooling). • Check which option describes removing water from the desiccant, not adding water to it.
