Abstract
A cooling circuit for a system for supplying and cooling a gas in a floating structure having a tank, the cooling circuit having a coolant flowing through it and including a main loop having: —a compression device; —a heat exchanger; —an internal heat exchanger; and —a turbocompressor, the cooling circuit includes a regulating branch connected to the main loop, the regulating branch having a valve that is configured to control the flow of coolant within the regulating branch, the main loop including a pressure sensor, the valve controlling the amount of coolant present in the main loop according to the pressure measured by the pressure sensor.
Claims11
A cooling circuit for a system for supplying and cooling a gas of a gas of a floating structure comprising at least one tank configured to contain gas in the liquid state, a refrigerant fluid intended to lower the temperature of the gas in the liquid state contained in the tank flowing through the cooling circuit, the cooling circuit comprising a main loop comprising:
- at least one compression device providing the compression of the refrigerant fluid;
- at least one heat exchanger configured to make an exchange of heat between the refrigerant fluid and the gas contained in the tank;
- at least one internal heat exchanger comprising a first passage where the refrigerant fluid circulates at a first pressure and a second passage where the refrigerant fluid circulates at a second pressure lower than the first pressure, the first passage being arranged downstream of the compression device and upstream of the heat exchanger, the second passage being arranged downstream of the heat exchanger and upstream of the compression device;
- and
- at least one turbo-compressor equipped with a compression member arranged between the compression device and the first passage of the internal heat exchanger and a turbine arranged between the first passage of the internal heat exchanger and the heat-exchanger, the compression member and the turbine being linked in rotation by a shaft,
- wherein the cooling circuit comprises a regulation branch connected to the main loop, said regulation branch comprising at least one valve configured for controlling the circulation of a refrigerant fluid within the regulation branch, the main loop comprising at least one pressure sensor, the valve controlling a quantity of refrigerant fluid present in the main loop depending on the pressure measured by the pressure sensor, the shaft only linking the turbine to the compression member of the turbo-compressor, the compression device being distinct from the turbo-compressor and being not linked to the shaft.
