Abstract:
A study has been made of various absorption cycle cooling units and associated components which would be required to maintain a habitable atmosphere in certain identified civil defense fall-out shelters, independent of any external energy sources. Of the many criteria which could be applied to these systems, four were selected as the bases for the final evaluation, e.e., cost, electrical requirement, volume and weight. The selected system consists of the aqueous ammonia absorption cycle cooling unit with heat rejection directly to ambient air from finned-tube condenser and absorber. This unit produces chilled water which is circulated through a finned-tube conditioning coil within the shelter area. Shelter heat is transferred to the chilled water by blowing shelter air and ventilation air through the conditioning coil. Heat to operate the absorption unit is supplied by combustion gases from a furnace designed to burn a volatile-producing fuel with coal as the preferred fuel. Manual power is applied to pump the chilled water and to circulate shelter air and cooling air. A suitably designed furnace needs to be developed, and the normally gas-fired absorption unit must be adapted to the furnace.
