Abstract
The invention provides a method for subcooling a cryogenic liquid (1), the method comprising providing a discharge element (2) comprising a first discharge element portion (23) comprising (i) a discharge element inlet opening (21), (ii) a throttle element (25), and (iii) a heat conductive wall (28); providing a cryogenic liquid (1) in an open container (10); immersing the first discharge element portion (23) in the cryogenic liquid (1) in the open container (10); and reducing a pressure in the discharge element (20) at a downstream side (26) of the throttle element (25), thereby inducing a flow of the cryogenic liquid (1) from an upstream side (24) of the throttle element (25) through the throttle element (25), wherein at least part of the cryogenic liquid (1) changes phase at the downstream side (26) of the throttle element (25), thereby providing a heat flow from the cryogenic liquid (1) surrounding the discharge element (20) to the first discharge element portion (23).
