Abstract
In an aspect, a system includes a cryogenic tank having a cooling system including a para-ortho catalyst device and a chiller, wherein the cryogenic tank is configured to store a cryogenic fluid, and a controller storing instructions in non-transitory memory that, when executed, cause the controller to conduct a cooling operation for the cryogenic tank via one or more of the para-ortho catalyst device and the chiller as a function of operating conditions.
Claims20
A system comprising:
- a cryogenic tank comprising a cooling system, wherein the cooling system comprises a para-ortho catalyst device and a chiller;
- one or more sensors configured for sensing parameters of the cooling system;
- and
- a controller in communication with the one or more sensors and storing instructions in non-transitory memory that, when executed, cause the controller to conduct a cooling operation for the cryogenic tank via one or more of the para-ortho catalyst device and the chiller as a function of operating conditions;
- wherein the para-ortho catalyst device comprises a para-ortho catalyst;
- wherein the cryogenic tank is configured to store a cryogenic fluid;
- wherein at least a part of the chiller is located in a region comprising the cryogenic fluid;
- and
- wherein the one or more sensors comprise a temperature sensor, a pressure sensor. a fluid level sensor, and a flow sensor.
A method comprising:
- determining, operating conditions based on data received from one or more sensors of a vehicle, wherein the vehicle comprises a cryogenic tank and wherein the cryogenic tank is configured to hold a cryogenic fluid and an ullage gas in an ullage space of the cryogenic tank;
- sending a signal by a controller to operate, via one or more actuators, one or more of a chiller and a para-ortho catalyst device based on the operating conditions;
- and
- operating one or more of the chiller and the para-ortho catalyst device in response to the signal;
- wherein the actuators comprise one or more valves for controlling a passage of cryogenic gas through the para-ortho catalyst device and a bypass circuit;
- and
- wherein the signal to the controller is sent by a control logic based on a determination of the operating conditions being met or by a human operator via a user input activating the controller.
A non-transitory computer-readable medium having stored thereon instructions executable by a computer system to perform operations comprising:
- determining, operating conditions based on data received from one or more sensors of a vehicle, wherein the vehicle comprises a cryogenic tank and wherein the cryogenic tank is configured to hold a cryogenic fluid and an ullage gas in an ullage space of the cryogenic tank;
- sending a signal by a controller to operate, via one or more actuators, one or more of a chiller and a para-ortho catalyst device based on the operating conditions;
- and
- operating one or more of the chiller and the para-ortho catalyst device in response to the signal.
