Japanese Patent JPS4956446
Kind Code:
A
Abstract:
Air may be dehumidified in an apparatus, comprising, in combination, a primary heat exchanger provided with a variable volume primary coolant for environmental cooling for thereby dehumidifying air in process, a secondary heat exchanger provided with a circulating secondary coolant for cooling the primary coolant, and means for controlling the circulation of the secondary coolant according to volume variations of the primary coolant. Suitable primary coolants include admixtures of a suitable liquid, for instance water, or an aqueous solution of a freezing point depressant, and ice. Volume variations of the primary coolant occur as ice in the admixture melts and liquid freezes and accumulates as ice.
