A method of controlling the injection of hydraulic fluid into a high pressure diaphragm compressor having a hydraulic system, the method including: measuring a representation of pressure in a high-pressure part of the hydraulic system of the diaphragm compressor, and maintaining a desired pressure in the high-pressure part of the hydraulic system by adding hydraulic fluid to the high-pressure part of the hydraulic system under the control of a controller on the basis of the measuring of pressure.

Method of controlling the hydraulic fluid pressure of a diaphragm compressor

A high-pressure compressor having a hydraulic system and a gas chamber, where the hydraulic system includes a reservoir, connected to a hydraulic fluid chamber by a hydraulic flow path and a pump assembly positioned in the hydraulic flow path, and the compressor furthermore includes a control element controlling the flow of hydraulic fluid in the hydraulic flow path and thereby the pressure in the hydraulic fluid chamber, where the control element and the pump assembly is configured for controlling the pressure of hydraulic fluid in the hydraulic fluid chamber when the compressor is not in operation.

Control of a high-pressure compressor

The invention related to a system for control of a hydrogen refueling station. The control of the hydrogen refueling station is optimized according to a high frequency tank profile in a time period between time A and time B. The high frequency tank profile includes selecting a first of the plurality of vessels as supply to the compressor during at least part of the refueling of the vehicle tank, the selection is based on pressure of hydrogen gas in one or more vessels of the supply storage. The control of the hydrogen refueling station is furthermore optimized according to a low frequency tank profile in a time period between time C and time D. The low frequency tank profile includes preparing one or more hydrogen refueling station components to enable a plurality of vehicle tank refuelings in the subsequent time period between time A and time B.
