Investigation of Methods of Inspired Gas Heating.

Abstract

Existing technology in both active and passive means of divers' gas heating was reviewed. It was found that there are very few firms engaged in the production of hardware for gas heating, but that the active hardware presently produced it generally successful in its operation. Although some passive devices are marketed for regenerative recovery of exhaled heat, no widely used breathing apparatus today employs regenerative heating, in spite of the obvious advantages. Specific areas where performance may be improved lie in reducing the heat lost between heater and the diver's head, in the active systems, and in design and construction of a regenerative heat-exchange insert for use in oral-nasal masks in the passive systems.
