Abstract
A heat accumulator is provided which has a heat exchanger embedded in a crystalline substance and has a maximum operating temperature greater than the melting point of the crystalline substance. The latter and the heat exchanger are integrated in a moulding bonded by means of crosslinked plastic. Preferably, the crosslinked plastic is crystalline and, at the same time, forms the crystalline substance. There is also provided an installation for the utilization of solar energy. The installation comprises a heat accumulator as described hereinbefore, a useful-heat exchanger and a solar energy absorber, which are connected together to form a heat transfer circuit. The installation is of particular use for the production of warm water.
