APARATO CAMBIADOR DE CALOR PARA LA CALEFACCION Y LA CLIMATI-ZACION DE LOCALES Y LA PRODUCCION DE AGUA CALIENTE Y FRIA A PARTIR DE LA ENERGIA SOLAR

摘要

A heat exchange apparatus comprises a storage space (1) for primary heat exchange fluid surrounded by an insulating casing (2) within a casing (3). The casing (3) forms a heat-exchange surface which embodies a pipe (31) forming part of a closed circulatory circuit connected to the space (1), the casing (3) being of spherical or ellipsoidal shape. Two apparatuses can be connected in parallel for providing hot and cold water. Reflectors can be attached to supports for such apparatus.
