Abstract
Provided is a hydrogen station that supplies hydrogen to an external hydrogen tank, the hydrogen station including: a reciprocating compressor that is driven by a driver of which revolution is controllable; a cooling device that is capable of cooling hydrogen supplied from the reciprocating compressor to the hydrogen tank; a temperature sensor that detects an internal temperature of the hydrogen tank or a temperature of the hydrogen supplied to the hydrogen tank; and a control unit that controls the revolution of the driver based on the temperature detected by the temperature sensor.
Claims12
A hydrogen station for supplying hydrogen to an external hydrogen tank, the hydrogen station comprising:
- a reciprocating compressor driven by a driver of which revolution is controllable;
- a cooling device for cooling hydrogen supplied from the reciprocating compressor to the external hydrogen tank;
- a temperature sensor for detecting an internal temperature of the external hydrogen tank or a temperature of the hydrogen supplied to the external hydrogen tank;
- and
- a control unit for controlling the revolution of the driver based on the temperature detected by the temperature sensor.
A hydrogen station for supplying hydrogen to an external hydrogen tank, the hydrogen station comprising:
- a reciprocating compressor driven by a driver;
- a cooling device for cooling the hydrogen supplied from the reciprocating compressor to the external hydrogen tank;
- a return passage comprising an adjustment valve and causing a discharge side of the reciprocating compressor at an upstream side of the cooling device to communicate with a suction side of the reciprocating compressor;
- a temperature sensor for detecting an internal temperature of the external hydrogen tank or a temperature of the hydrogen supplied to the external hydrogen tank;
- and
- a control unit for adjusting an opening degree of the adjustment valve based on the temperature.
A hydrogen station for supplying hydrogen to an external hydrogen tank, the hydrogen station comprising:
- a first reciprocating compressor driven by a driver of which revolution is controllable;
- an intermediate passage through which hydrogen compressed by the first reciprocating compressor flows;
- a second reciprocating compressor connected to the first reciprocating compressor through the intermediate passage;
- a cooling device for cooling the hydrogen supplied from the second reciprocating compressor to the external hydrogen tank;
- a pressure sensor for detecting an internal pressure of the intermediate passage;
- and
- a control unit for controlling the revolution of the driver driving the first reciprocating compressor based on the internal pressure.
