Abstract
Abstract A cooling system for a deep submersible vehicle having a cabin and a false floor. The cooling medium of the cooling system has a high specific heat and is stored in the normally unused space beneath the false floor. The cooling media is super-cooled or frozen by the refrigeration system of a mother ship. One heat exchanger is located in the cooling medium and another heat exchanger is located in the crew department of the cabin. A circulation system is provided between the two heat exchangers. Heat for the vehicle is provided by the vehicle passengers, electric equipment, a CO2 scrubber and a heater if required. The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A cooling component control of a system for sustaining life in a submersible vehicle, said vehicle including a cabin with a false floor, and a life sustaining system including a cooling component comprising in combination: a. medium of high specific heat positioned below the false floor; b. external refrigerating means for super-cooling said medium to its freezing point; c. a first heat exchanger located in said medium; d. external refrigerating means being intermittently operatively connected to said first heat exchanger; e. a second heat exchanger located in the cabin; f. an accumulating tube operatively connected between said first and second heat exchanger; g. said accumulating tube containing a heat removing fluid; h. pump means operatively connected between said first and second heat exchangers and the accumulating tube to control the circulation of said fluid.
Claim 2
Dependent Claim
