摘要:
Zur Ausnutzung mechanischer Energie aus Windener gieanlagen oder von elektrischer Energie aus dem Netz in Zeiten schwacher Belastung vornehmlich im Sommer wird eine chemische Wärmepumpe mit einem chemischen Lang zeitspeicher zur Aufnahme der zugeführten Exergie in Form mechanischer oder elektrischer Energie eingesetzt, wobei der chemische Speicher Exergie zum Pumpen von Anergie in die zu beheizenden Räume bei Bedarf abgibt.
摘要:
Accumulateur constitué d'un grand volume de masse solide, tel que le sous-sol, dans lequel sont disposés un nombre d'échangeurs de chaleur, qui comportent chacun un premier tuyau en contact avec la masse du sous-sol, et un deuxième tuyau disposé à l'intérieur du premier. Système de cimentation ou engagement d'une nappe hydri que. Parois extérieures d'immeubles comportant des cou ches d'isolation et des réservoirs plats (r, s) à circulation d'eau. Les réservoirs (r, s) font fonction de capteurs solaires et d'éléments pour le chauffage dans une installation de chauffage à basse temperature.
摘要:
A method at a heat pump process and a heat pump device where a hydrophilic liquid and a hydrophobic cooling medium, which is chemically and physically inert in presence of the hydrophilic liquid, are mixed. The mixture is fed into an evaporation chamber where the cooling medium is brought to boil while taking up heat from the hydrophilic liquid. If for instance water is used this can be allowed to freeze, whereby the phase conversion heat is used.
摘要:
A self-contained heat pump system comprises mounted with an enclosing housing a fossil-fueled engine (6), a compressor (7) and a heat pump circuit including the compressor and comprising a condenser receiver (10), an ; expansion valve (15) and an evaporator (2). Means (11,27) are provided for circulating water to be heated through the condenser receiver (10) and through heat exchangers (9,8) connected to the engine coolant and the engine exhaust. Air (1) is passed through the evaporator (2) to be cooled thereby . after having been drawn through the housing over the exterior of the condenser receiver (10), the compressor (7), the engine (6) and the heat exchangers (8,9) in order to absorb excess heat therefrom prior to being cooled in the evaporator. The system is particularly of use for controlling the environment in a glasshouse with humid air being drawn from the glasshouse space and being mixed with fresh air drawn in from the atmosphere in the housing before being passed through the evaporator for extraction of heat therefrom. The engine speed is continuously variable across a suitable operating range and controlled so as to vary across that range in between compressor loading and unloading steps.
摘要:
A heat exchanger comprising a heat-conducting structure (2), e.g. sheet, supporting a continuous heat-conducting pipework (4) e.g. of serpentine shape, through which liquid can pass. There are ducts with pervious walls (3) spaced from and adjacent to the pipework (4). Solid material (5) is housed adjacent to but external of the ducts (3).
摘要:
A solar panel having an interior insulated heat storage means, a solar radiation collector wall mounted on a first side of the storage means having a collector surface for exposure to solar radiation and a heat emitterwall mounted on a second side of the heat storage means opposite the first side having an emitter surface for exposure to a space to be heated. The panel further includes a collectorfluid conducting path forthe conduction of collector fluid around an endless loop from a primary portion where there is heat exchanging contact with the collector wall to a secondary portion where there is heat exchanging contact with an emitter fluid in the interior heat storage means. Emitter fluid is contained within an emitter fluid conducting path which moves around an endless loop from a primary portion where there is heat exchanging contact with the collector fluid and the heat storage means to a secondary portion where there is heat exchanging contact with the emitter wall. A heat exchanger panel located within the interior heat storage means has an outer surface in thermally conductive association with the collector fluid in the secondary portion of the collector fluid path and an inner surface in thermally conductive association with the emitter fluid in the primary portion of the emitter path. The collector and the emitter walls each are made of a heat conducting sheet material. The panel construction provides an improved heat collection and transfer efficiency to an interior space to be heated.
