PROCESS AND DEVICES FOR THE FREE MUTUAL CONVERSION OF HEAT AND WORK AND FOR THE APPROXIMATE EXCHANGE OF THE TEMPERATURES OF TWO HEAT CARRIERS BY HEAT TRANSFER

摘要

Heat and work are freely mutually converted by changing the temperature of a body by the application and abstraction of heat periodically between an upper To and a lower temperature Tu by the temperature exchange process of the invention, where a change in volume shifted in phase in relation to its isobaric change is imposed upon the body. In the process for the approximate exchange of the temperature of two heat carriers by heat transfer, two heat carriers are brought into mutual heat contact over a region and are mutually shifted in their general movement. The heat resistance inside the heat carriers in their general direction of movement is kept as high as possible while the heat resistance is kept as low as possible in the direction perpendicular to the general direction of movement.
