Marine energy storage unit with thermal runaway safety barriers to prevent cell temperature increase, said marine energy storage unit comprises at least one closed module cabinet (10) with a plurality of stacked battery cells (4) and an internal cooling system. The internal cooling system comprises an enclosed cabinet cooling circuit (3) with a water-to-air exchanger (20) for air cooling of the battery cells (4), and the water-to-air exchanger (20) is connected to a water-to-water heat exchanger (30) for receipt of water from an external source.

A raw water isolator for watercraft for providing treated fluid to loop of air conditioning units, freezers, ice makers, gyro stabilizers and the like systems. The raw water isolator provides a closed loop of treated fluid to prevent such systems from exposure to raw water known to contain biological material capable of fouling the units, and associated corrosion when salt water is used for the cooling mechanism. The apparatus employs a storage and expansion tank for holding a volume of fluid that is circulated through the marine units. A heat exchanger selected for ease of cleaning provides heat transfer between the cooling fluid and raw water.

A ventilation system is provided for persistent natural ventilation by circulation of air between an interior space and an external environment. In one example, the ventilation system includes an air intake including a domed upper cover with exterior windows which allow air to circulate through an upper chamber, a baffle around floatable elements, the baffle including an annular protective screen and valve windows, a lower chamber fluidly coupled to each of the upper chamber via the baffle and an interior duct via a main window thereof, wherein the interior duct is fluidly coupled to the interior space, and wherein the floatable elements are positioned on respective seats when no liquid is present, each of the seats spaced a distance opposite to a respective one of the valve windows. Responsive to liquid entering the upper chamber via the exterior windows, the valve windows may be automatically blocked by the floatable elements.

A passenger cabin air distribution system includes a ventilation system and an ejector-diffuser. The ventilation system is operable to provide a conditioned air. The ejector-diffuser is positioned to receive a flow of the conditioned air from the ventilation system. The ejector-diffuser includes an induction unit and a diffuser section. The induction unit includes a secondary inlet in communication with a cabin air from a passenger cabin and is configured to mix the flow of the conditioned air with an induced flow of the cabin air into a mixed air. The diffuser section includes a discharge to eject the mixed air to the passenger cabin. The diffuser section is shaped to provide for efficient mixing with low backpressure in order to maintain the low motive pressure in the nozzle.

The invention belongs to the technical field of ships, and relates to an aerogel heat preservation ship rescue cabin, which comprises a cabin body. The cabin body and arc-shaped plates are made of aerogel materials. Water pumping devices are symmetrically sleeved outside the cabin body near two sides. A straight pipe is connected between the two water pumping devices. Strip-shaped water outlet holes are formed at front and rear sides of the straight pipe in a penetrating manner. A heat insulation plate is sleeved on the cabin body and hollow, and two ends thereof are communicated with the water outlet holes at front and rear sides of the straight pipe. Multiple drainage holes are formed in the inner wall, opposite to the cabin body, of the heat insulation plate in a penetrating manner. Multiple evaporation holes are formed in the top of the heat insulation plate in a penetrating manner.
