title: Temperature control system for water-perfused suits.
abstract: A system used to control skin temperature in human subjects wearing water-perfused garments is described, It supplies 8 l/min at 10 psi with water temperature controlled within +/-0.1 degree C. Temperature control is facilitated by a low circulating thermal mass and a fast responding heater based on a commercially available quartz heat lamp. The system is open so that hot or cold water can be added from the building mains to produce rates of change or water temperature exceeding 5 degrees C/min. These capabilities allow semiautomatic control of skin temperature within +/-1 degree C of desired wave forms. Potential hazards and associated safety devices are described.
