Abstract
Abstract An improved cooling and ventilating system for removing metabolic heat, waste gases and water vapor generated by a wearer of an hermetically sealed spacesuit. The cooling system is characterized by a body suit having a first circuit for simultaneously establishing a cooling flow of water through the thorax and head sections of the body suit including circulation patches mounted in the thorax section and head section of the body suit, a second circuit for discharging a flow of gas throughout the spacesuit and a disconnect unit for coupling the circuits with a life support system externally related to the spacesuit.

In combination with a hermetically sealed spacesuit including a bulbous helmet affixed to a thorax section of a rigid, tubular configuration, an improved cooling system for removing metabolic heat and gaseous wastes generated by a wearer comprising: an elastomeric body suit including a thorax section, leg sections, arm sections and a head section adapted to be donned by a wearer and received within said spacesuit; a quick disconnect unit having a first section mounted on said spacesuit interior in reach of said wearer and a second section mounted on said body suit and adapted to be mated in a releasably coupled relationship with said first disconnect section, said first section having first and second inputs and an output mating with first and second outputs and an input, respectively, on said second section; circuit means for channeling a flow of water through the thorax section and the head section of said body suit, said circuit means coupled between said first outlet and said inlet of said second section of said disconnect unit; said spacesuit having a water inlet orifice, a water outlet orifice, a gas inlet orifice, and a gas outlet orifice grouped in said thorax section, said orifices being adapted to link to a life support system external to said spacesuit; means for ducting gas from said gas inlet orifice to the interior of said helmet and to said second inlet of said first section of said disconnect unit; means for ducting water from said water inlet orifice to said first input of said first section of said disconnect unit and for ducting water from said output of said first section to said water outlet orifice; a gas distribution network comprising a manifold mounted on said body suit and a flexible conduit connecting said manifold to said second outlet of said second section of said disconnect unit; and flexible tube means secured to said body suit for channeling gas from said manifold to all arm and leg extremities of the wearer.
