Reservoir for storing latent heat

摘要

The reservoir is used to store latent heat, and has reservoir material in an inner tank (3) through which a heat-carrying medium flows, without making direct contact with the material. The medium preferably flows through a number of pipes which pass through the tank, and which open into a collecting space at both ends. The tank is enclosed in an outer container, in order to form an insulating space. A pressure limiting valve (6) is sealed directly into an opening (1) in the tank wall (2), so that one end (61) of the valve projects into the expansion volume (7) of the tank, and the other end (62) opens into the collecting space for the medium. The valve may preferably be soldered into the opening in the tank wall.
