Accumulator-exchanger device

Abstract

An accumulator-exchanger of the filling-body type, the rigid spherical shells of which are partially filled with a heat and/or cold storage agent having a high liquid-solid transformation latent heat, such as water, salt hydrates or paraffins, and with a compressible material for absorbing the variations in the volume of the storage agent during its phase change. Projections for increasing the exchange surface area consist of raised features inscribed on the shells of the filling bodies, which raised features all have an axis of symmetry passing through the center of symmetry of their base and through the center of the filling body. The bases of the raised features are all equal and identical and the raised features are uniformly distributed over the entire surface of the shell.
