Book Description
A thermoelectric heating and cooling module was constructed for installation in a water to water air conditioning system aboard a submarine. This module has a cooling rating of 2550 BTU/hr. at a coefficient of performance of 0.75 and an operating current of 35 amperes dc. This rating was based on a 85 F sink water temperature and a chill water temperature of 55 F. The unit was designed to withstand submergence pressures and the corrosive effect of sea water in all water passages. It occupies a volume 1 ft. by 1 ft. by 3 inches and was designed for ease in stacking into larger capacity units without additional space being required for coupling between units. It has a weight of 50 pounds.

Book Description
A single-tube subunit of the one-ton model has been constructed and successfully operated for a period of 35 hours. Performance was very close to that predicted in the design. The results established the adequacy of the basic design. All components for the one-ton unit have been fabricated. However, the complete unit has not been assembled because the thermoelectric modules required further work and modifications. The major problem with the thermoelectric modules was marginal-to-unsatisfactory high voltage insulation especially in the presence of moisture. A substantial number of modules have failed under these conditions. It appeared that most of these failures could be attributed to poor quality control of the hard-coated aluminum plates, specifically, insufficient care in making the radii on the edges and otherwise preparing pieces for the hard-coating process. In addition, inadequate protection at the edges from moisture appeared to be a contributing factor. It was felt, however, that the hard-coat insulation scheme adopted was fundamentally adequate and that proper process control would yield satisfactory modules. Several modules have been assembled to evaluate these improvements which consist mainly of minor changes in the structure and configuration, tightening of tolerances, and improved control of the anodizing process.
