Title (EN) METHOD AND APPARATUS FOR HEATING BY HEAT PUMPING
(FR) PROCEDE ET APPAREIL DE CHAUFFAGE PAR POMPE A CHALEUR
Abstract: front page image
(EN)Method and apparatus for heating by means of heat pumping. The heat pumping is effected in two separate pump stages (15-22-23, 16-24-25; 115-122-123, 116-124-125). In order to reduce the energy losses air is being circulated through a heat-insulated space (10; 110) which has a substantially adiabatic relationship to the surroundings thereof and includes the condenser (23; 123) of the first stage (15-22-23; 115-122-123) and the evaporator (24; 124) of the second stage (16-24-25; 116-124-125) and the compressors (15, 16; 115, 116) and drive machinery (12, 13, 14; 112, 113, 114) of the two stages. Heat absorbed by the air from the condenser of the first stage, the compressors and the drive machinery is supplied to the evaporator of the second stage. The pump stages have different pressure and temperature grants and are thermodynamically dimensioned in such a way that the total of the heat absorbed equals the heat of vaporization of the second stage.
(FR)Le pompage de la chaleur est effectue dans deux etages separes de pompe (15-22-23, 16-24-25, 115-122-123, 116-124-125). Pour reduire les pertes d"energie on fait circuler l"air a travers un espace d"isolation thermique (10; 110), espace qui est essentiellement en relation adiabatique par rapport a l"entourage et comprend le condenseur (23; 123) du premier etage (15-22-23; 115-122-123) et l"evaporateur (24; 124) du second etage (16-24-25, 116-124-125) et les compresseurs (15, 16; 115, 116) et les machines d"entrainement (12, 13, 14; 112, 113, 114) des deux etages. La chaleur absorbee par l"air du condenseur du premier etage, les compresseurs et les machines d"entrainement, est fournie a l"evaporateur du second etage. Les etages de pompes ont des gradients de temperature et de pression differents et sont dimensionnes thermodynamiquement de maniere telle que la totalite de la chaleur absorbee soit egale a la chaleur de vaporisation du second etage.
