Abstract:
A heat exchange system providing a heat medium in a loop circuit circulating heat exchanger to transfer heat, which mainly uses a water as base material, and the liquid state heat medium is formed by mixing the water with an improving agent or heat carrying particles. The heat medium is filled in a loop circuit heat exchange circulating path having an internal pressure space, and the internal pressure space is used to raise the boiling point and reduce freezing point phase transition temperatures of the water to comply with implementation needs. Hence, the present invention is able to achieve satisfactory strength of heat transfer and unequivocally resolve environmental issues.

Abstract:
This invention relates to an electrically heated radiator with heat-accumulating properties. For accumulation of heat in the night-time and for giving off the heat under determined conditions, the radiator according to the invention comprises a heat-insulating container (1) which has an inner space (2) and one or more heat accumulation vessels (3) therein. One or more electrical heating elements (4) for heating the heat accumulation vessels (3) are also housed in the container. The container (1) is surrounded by a jacket (5), so that an air gap (6) is formed around the container (1). A regulator (7) is adapted, in dependence on the ambient temperature of the radiator, to first open one or more passages (8, 9) between the inner space (2) of the container (1) and the air gap (6) in response to the ambient temperature of the radiator having fallen to a first level and to subsequently open at least one passage (10) between the air gap (6) and the surroundings of the radiator in response to the ambient temperature of the radiator having dropped fallen to a second level lower than the first level by moving at least one damper along the outer side of the jacket (5).
Abstract:
A heat storage device is disclosed in which grooves for supports supporting heat storage vessels, each vessel storing therein a heat storage material, are defined on the lower surface of each of the vessels so that the supports do not project from the bottom surface of each vessel.
