Abstract
Abstract The present invention relates to a bag-like container, and a spherical container in which a latent heat accumulating meterial is enclosed, and a heat accumulating apparatus employing such containers. A heat accumulating mat material (A) is of a flat bag-like container divided into a plurality of sections, where a latent heat accumulating substance is enclosed. A spherical container (1A) has a heat transfer area enlarging portion of a recess (102), a groove (103). A solar heat accumulating greenhouse 2A has a radiator heat exchanging portion (2B, 2D), a heat accumulating tank 2C and a forced circulation liquid system.
