From the skin out, the Apollo A7LB spacesuit began with an astronaut-worn liquid-cooling garment, similar to a pair of "long-johns" with a network of spaghetti-like tubing sewn onto the fabric. ISRO’s liquid cooling and heating garment is meant to the worn as a one-piece lightweight comfort inner-wear. The model was utilized in the design process of an automatic controller intended to maintain thermal neutrality of an exercising subject wearing a liquid cooling garment. The role of the liquid-cooling and ventilation garment is, obviously, to keep the body cool. Our suit’s liquid cooling and ventilation under-garment consists of 300 feet of thin tubing that circulates cooling water around the astronaut’s body.
