The object of the present invention is a water heater (1) comprising:- a casing (10) wherein at least one water storage tank and at least one heating means are arranged and housed,- at least one electrical junction box (3) wherein exclusively passive components, comprising at least the terminals of the main power cables (60) of the said water heater (1) and possible terminals of the auxiliary wiring cables (61) are housed,characterised in thatsaid junction box (3) is movable between a housing position, wherein it is removably fixed to an installation surface, and a remote position, wherein it is released from said installation surface.

The object of the present invention is a heat pump water heater (1), comprising a pump group contained in a casing (3) above a housing (2) containing one or more storage tanks for the volume of water to be heated and related heat exchangers. Said casing (3) of the pump group comprises openings (4.IN, 4.OUT) for the inlet and exhaust air.According to the invention, said opening (4.IN) for the inlet air comprises a ventilation grid (7.IN) whereon an air filter (5) is placed, removably fixed to an annular flange (7.1) of said grid (7.IN).

The object of the present invention is a heat pump water heater (1) comprising a lower casing (11) containing one or more tanks for accumulating the volume of sanitary water and the related heat exchangers, generally condensers, an upper casing (10; 10.A, 10.B) containing a pump group comprising at least one fan (5) and a first heat exchanger (8), generally an evaporator (8). Said fan (5) and evaporator (8) are constrained to each other by fixing means (3) which comprise at least: first fixing elements (30) capable of fixing a base (53) of the volute (50) of said fan (5) to a partition wall (12) of said upper (10; 10.A, 10.B) and lower (11) casing, second fixing elements (31) capable of fixing said volute (50) to the front side (81) of said evaporator (8). Said upper casing (10; 10.A, 10.B) comprises: a front shell (10.A) and a rear shell (10.B), mutually coupled to each other by means of releasable coupling means, while said fixing means (3) further comprise a releasable constraint system (32) fixing said volute (50) of the fan (5) to the rear side (82) of said evaporator (8).

The object of the present invention is an apparatus (1, 1') for heating or cooling and storing a liquid comprising:- a set of tanks including two tanks (31, 32) of substantially cylindrical shape, placed side by side with parallel axes so as to define a passage region (33) comprised between the mutually facing surfaces (313, 323) thereof, the tanks (31, 32) in mutual fluidic connection and preferably stiffly constrained with each other,- at least one heat exchanger (4, 4a, 4b, 4b', 4c) preferably of the microchannel type comprising channels configured to allow a refrigerant fluid to flow, the channels being placed side by side and substantially coplanar so as to define a heat exchange surface having a winding length defined along a winding direction perpendicular to the axes of the tanks, and a height a, defined between an upper end and a lower end of the at least one exchanger, said height a being substantially perpendicular to the winding length,wherein each channel preferably includes a plurality of microchannels, and wherein the at least one exchanger comprises two lateral portions (41, 42) wrapped around at least part of the outer curved surface of each tank (31, 32), respectively, and a connecting portion (44) defined between said two lateral portions (41, 42) and which fits into the passage region (33), forming in cross-section a loop of opposite curvature with respect to the portions (41, 42) wrapped around part of the outer surface of the tanks (31, 32).

The object of the present invention is a hydraulic separator (50) configured to enable the hydraulic and functional integration of a boiler (3) and of a heat pump (2) of a hybrid system (1) adapted to serve at least a heating and/or cooling system of the environment (4). Said hydraulic separator (50) comprises and/or cooperates with a bypass (6) capable of compensating for any malfunctions or failures or breakdowns of the heat pump, in particular of the circulator (20) thereof, ensuring functional continuity for at least the environmental heating service.

The object of the present invention is a combined system (1) adapted to serve a thermal system (4) for indoor heating and/or cooling and/or a sanitary system (4') for the preparation of sanitary water comprising at least a heat pump (2), at least two storages (3; 3.M, 3.V) for the preparation and storage of said sanitary water to be allocated to a user and a connection kit (5) capable of hydraulically and functionally connecting said heat pump (2) and said at least two storages (3; 3.M, 3.V).

The system relates to an internal-reflux distillation column that integrates a rotating heat exchanger as the structured filling. The column (container 10) is a vertical vessel (axis X) with a lower vapour inlet, a condensate outlet, and a top vapour outlet (15) connected to an external condenser (22). A distillate-reflux inlet (18) near the head allows part of the condensed product to be returned to the column. A heat exchanger (5) is mounted inside on a shaft (6) that rotates around axis X, driven by a motor (60); it operates in counter-current mode with a refrigeration fluid supplied through internal ducts (610,620). The rotor may be a finned tube, the fins having a helical structure.The system is suitable for batch or continuous fractional distillation of multicomponent mixtures in pharmaceutical, fine-chemical, biotech and food processes.
