Abstract:
L'invention se rapporte à un récipient de condensation (9), adapté à la condensation de produits de purge d'un réseau de vapeur, tel qu'un réseau de chauffage urbain, le récipient comprenant : - un orifice bas (1 1 ) d'entrée d'eau et un orifice haut (12) de sortie d'eau, ces deux orifices étant prévus pour être connectés à un circuit de refroidissement; - un orifice d'alimentation (13) en vapeur, relié à un diffuseur (15) de vapeur disposé entre les deux orifices bas et haut; la vapeur d'eau introduite dans le récipient de condensation (9) via le diffuseur (15) se condensant au contact de l'eau contenue dans le récipient de condensation (9) qui se réchauffe et circule à travers le récipient de condensation (9) par effet thermosiphon.
Abstract:
L'invention concerne un dispositif de sécurité pour une installation de chauffage comprenant : une chaudière (3), un bac (5) de réception de condensats équipé d'un capteur (6) d'un niveau de sécurité; un circuit (1) primaire de chauffage de l'habitation; une boucle de remplissage reliant le circuit (1) primaire à une arrivée d'un fluide dit secondaire (F2), caractérisé en ce qu'il comprend un dispositif (8) de commande d'une vanne de sûreté agencée en amont de la boucle de remplissage et adapté pour commander la fermeture de ladite vanne (7) de sûreté dès que ledit capteur (6) détecte que ledit niveau de sécurité est atteint dans ledit bac (5) de réception. L'invention concerne également une installation équipée d'un tel dispositif de sécurité et un procédé de sécurisation d'une installation de chauffage.
Abstract:
A combined system (10) for the production of hot water which comprises : a solar apparatus (11); a wall -mounted gas boiler (13); a hydraulic network (14); and a mixer/diverter valve assembly (15; 15*; 15**; 15***). The system (10) is characterized in that the mixer/diverter valve assembly (15; 15*; 15**; 15***) is substantially contained as a whole in the casing (20) of the second apparatus (13). Furthermore, the valve assembly (15; 15*; 15**; 15***) is compact and comprises circuit elements (EL1, EL2, EL3, EL4) reciprocally interconnected so as to form a single block.
Abstract:
A hydraulic device (1) for feeding and controlling a fluid stream towards users, comprising a delivery branch (2) of the stream towards users, a return branch (3) of the stream from users, a measuring instru¬ ment (4) of the instantaneous flow rate of the stream in the return branch (3), a first hydraulic path (5) put- ting the delivery branch (2) in fluid communication with the return branch (3), a shut-off valve (6) placed on the delivery branch (2), which can be operated between a first operating configuration in which it allows the stream to get through the delivery branch (2) so as to reach the users and a second operating configu¬ ration in which it diverts the stream from the delivery branch (2) towards the return branch (3) without get¬ ting through users, a first balancing valve (10) placed on the delivery branch (2), and a second balancing valve (11) placed on the first hydraulic path (5), wherein the first hydraulic path (5) fits into the return branch (3) upstream, with respect to the flowing direction (R) of the stream in the return branch (3), from the measuring instrument (4).
Abstract:
A method for automatically feeding a closed liquid system from a liquid source according to need by creating between the liquid source and the closed liquid system a feed buffer formed from liquid, in which between the liquid source and the feed buffer only liquid flow in the direction of the feed buffers is allowed and from the feed buffer to the closed liquid system only dropwise liquid transport is admitted. The feed buffer can be realized with a cylindrical drip feeder with inlet, outlet and freely movable plunger, which can close the outlet in an abutting position while leaving clear a minuscule leakage channel and is provided with a passage with a non-return valve in the direction of the inlet. Such a drip feeder can, with or without insertion of a storage container for liquid, be connected with, for instance, a liquid system, such as a central heating system with pipe system, boiler and expansion tank.
Abstract:
A valve (6, 100) comprising an inlet (42, 108) and an outlet (110) and a path of fluid communication between the inlet and outlet, means for selectively allowing fluid to flow along the path of fluid communication and means for preventing fluid from flowing along the path of fluid communication, and an opening (9, 104) from the valve to atmosphere, whereby when fluid is prevented from flowing along the path of fluid communication, an atmosphere gap is created between the inlet and the outlet.
Abstract:
The invention relates to a heat pump system (1) which is configured particularly to facilitate servicing of the system. The system (1) is accommodated in a floor-standing cabinet (10), in which the refrigerant circuit is combined to form a compact unit (4) mounted on a bottom plate (11). This unit (4) can be readily removed from the heat pump in general, and can be lifted from its attachments or supports (12) with the aid of an arrangement particularly developed for this purpose, and withdrawn from the cabinet (10) for service or replacement. The refrigerant unit can be exchanged in such a simple fashion as to obviate the need to employ workmen specialized in this art or the need to use special tools, and can be carried out by the unskilled person while conforming with current regulations.
