Project Innovation + Advantages:

Zephyr Innovations is developing an alternative to the standard, vapor-compression (VC) driven air conditioner that uses no synthetic refrigerants. Zephyr’s solution employs evaporative cooling preceded by efficient liquid desiccant dehumidification. The key challenge in any desiccant-based dehumidification system is the removal of moisture from the desiccant so it can be reused. This is typically done by heating the desiccant to boil off water. Zephyr’s differentiator is its desiccant regeneration system which avoids direct desiccant heating and doubles dehumidification and cooling efficiency over today’s most efficient VC systems.
