Cooling Shirt for First Responders

TDA Research’s personal cooling shirt is useful for workers in hot environments, outdoor sports enthusiasts and first responders. It is designed to be lightweight, comfortable, affordable, durable and simple to operate. The design is based on a simple principal of many small channels attached to a wicking garment. Air is blown through the channels using a small battery powered fan. A small hydraulic diameter of channels increases the mass transfer rate so sweat can evaporate even in humid climates. This concept works well for both indoor and outdoor applications.

• Lightweight.

• Cools and dehumidifies.

• Transfers heat from the inside of the suit to the dirty environment, but keeps the clean and contaminated air streams separate.

• The dry (about 15% RH) clean air is cooled to about 77°F and returned to the first responder.

• The cool, dry air is distributed to the hands, head, and feet within the Personal Protective Equipment (PPE) with a lightweight fabric, internal duct system.
