A leap forward in cooling efficiency

Greentown Alumni

About the Company

Zephyr is commercializing a refrigerant-free technology that independently cools and dehumidifies and halves the power consumption of today’s most efficient systems.

About the Solution

Zephyr is developing an alternative to the standard, vapor-compression (VC) driven air conditioner that will reduce energy consumption by 50% over today’s highest-efficiency ACs while using no refrigerants. This breakthrough is achieved by replacing conventional ACs’ inefficient VC method with one employing evaporative cooling in conjunction with a novel, high-efficiency liquid desiccant dehumidification system.
