The following disclosure relates to a compression tool for compressing a substack of electrochemical cells having a first plate, a second plate, and a plurality of electrochemical cells positioned between the first plate and the second plate. The compression tool is configured to be maintain on the substack after the substack is added to the electrochemical stack assembly and the electrochemical stack assembly commences operation of an electrolysis reaction.

A refrigeration system is provided. The refrigeration system (900, 923, 931) comprises: a gas cooler (908) or a condenser configured to reject first heat from a first fluid stream of a fluid that is at a first pressure and that is in a supercritical state or subcritical state; an evaporator (910) configured to absorb second heat into a second fluid stream of the fluid that is at a second pressure that is lower than the first pressure and that is in a liquid state, a vapor state, or a two-phase mixture of liquid and vapor; and a rotary pressure exchanger (40, 902) comprising: a first manifold (52) forming: a first manifold inlet (56) configured to receive the first fluid stream via a first path from the gas cooler (908) or the condenser; and a first manifold outlet (58) configured to output the first fluid stream in the liquid state or in the two-phase mixture of liquid and vapor to the evaporator (910); a second manifold (54) forming: a second manifold inlet (60) configured to receive the second fluid stream via a second path from the evaporator (910); and a second manifold outlet (62) configured to output the second fluid stream in the supercritical state or the subcritical state to the gas cooler (908) or the condenser [para. ; and a rotor (46) forming channels (70), wherein the rotor (46) is configured to: receive the first fluid stream via a first distal end of a first channel (70) of the channels from the first manifold inlet (56); receive the second fluid stream via a second distal end of the first channel from the second manifold inlet (60); exchange pressure between the first fluid stream and the second fluid stream; provide the first fluid stream from the first channel to the first manifold outlet (58); and provide the second fluid stream from the first channel to the second manifold outlet (62)

A pressure exchanger (300) configured to exchange pressure between a first fluid and a second fluid is provided. The pressure exchanger comprises one or more flushing outlets (346A, 346B) configured to couple to one or more first valves (390A, 390B), wherein the one or more first valves (390A, 390B) in an open position are associated with a flushing operation.

Es wird ein Parksystem (2) zum Parken von Zweirädern (6) bereitgestellt. Das Parksystem weist mindestens eine Parkeinheit (12) auf, die zur Aufnahme eines Zweirads (50) ausgestaltet ist, und das ferner zumindest eine verschließbare Einfahröffnung (6) zum Einfahren eines Zweirads (50) in einer Einschubrichtung (A) in die Parkeinheit (12) aufweist. Die Parkeinheit (12) weist eine Parkvorrichtung (19a, 19b) mit einem Schlitten (30) auf, wobei der Schlitten (30) zum Auffahren zumindest eines Rads des Zweirads (50) ausgestaltet ist, wobei der Schlitten (30) so ausgestaltet ist, dass er in und entgegen der Einschubrichtung (A) horizontal bewegbar ist, und wobei der Schlitten (30) eine Feststelleinrichtung aufweist, die ausgestaltet ist, um das Zweirad (50) auf dem Schlitten (30) zu fixieren, so dass das fixierte Zweirad (50) in Einschubrichtung (A) in die Parkeinheit (12) unter Verfahren des Schlittens (30) einbringbar ist.

A method is provided. The method comprises: obtaining, by a processing device, a first indication of a speed of operation of a pressure exchanger, (PX), of a heat transfer system; determining, based on the first indication of the speed of operation of the PX, a target speed of operation of a low-pressure booster, wherein an outlet of the low-pressure booster is coupled to provide fluid to a low-pressure inlet of the PX; and causing, based on the target speed of operation of the low-pressure booster, an adjustment to a speed of operation of the low-pressure booster.
