Abstract: The invention relates to a method for operating a liquefied gas storage tank (1) having a tank volume (2) for receiving LNG and boil-off gas (BOG), wherein a gaseous BOG stream and a liquid LNG stream are fed to the tank volume, and wherein the BOG stream is introduced into the LNG stream, and wherein subsequently the resulting BOG-LNG mixture is introduced into the tank volume. The invention also relates to a corresponding liquefied gas storage tank.

Abstract: A method for operating a vapor compression system is disclosed. The vapor compression system comprises a compressor, a condenser, at least one expansion device, an evaporator, said evaporator comprising at least two evaporator paths arranged fluidly in parallel, and a distribution device arranged to distribute refrigerant among the evaporator paths. The method comprises the steps of obtaining at least two predefined distribution keys, each distribution key defining a distribution of available refrigerant among the evaporator paths, detecting one or more operational settings of the vapor compression system, selecting one of the at least two predefined distribution keys, based on said detected operational setting(s), and distributing refrigerant among the evaporator paths in accordance with the selected predefined distribution key.

Abstract: The invention relates to an axial piston drive with a continuously adjustable piston stroke, which comprises a drive shaft (10, 12) on which a swash plate (16) is supported in a crank chamber (14) in such a way as to be tiltable and displaceable in the axial direction, as well as a controller (18, 20) by means of which an tilt angle and an axial position of the swash plate (16) can be adjusted, and at least one piston (26, 28) connected to the swash plate (16) so that it can be actuated to move within a cylinder (22, 24).

Abstract: An air conditioner for motor vehicles has a refrigerant circuit in which the refrigerant is brought into a wet vapor state. The refrigerant circuit is comprised among other things of at least one compressor (37) and a pressure ramming machine (14′) which serves as an expansion device. By means of the pressure ramming machine (14′), energy is recovered during the expansion process which can be used in the circuit for compressing the refrigerant. In addition, a method for operating an air conditioner for motor vehicles is described, according to which a pressure ramming machine is integrated into the refrigerant circuit and refrigerant is brought into a wet vapor state in the pressure ramming machine (14′).
