The refrigeration available in a liquefied gas is utilized to refrigerate a fluid having a boiling point above the boiling point of the liquefied gas which is sprayed into an endless conduit such that the liquefied gas is vaporized. The resulting thermal currents and momentum of the spray are effective to provide the motive power for circulating the gas throughout the conduit and into indirect heat exchange with the fluid to be refrigerated. The temperature of heat exchange means in the vicinity of the location at which the fluid is introduced into such indirect heat exchange may be regulated by controlling the magnitude of the gas flow throughout the conduit to thereby avoid freezing of components of such fluid. The use of shaft power (such as a fan or blower) for circulating the gas flow throughout the conduit is avoided and the utilization of refrigeration available in the liquefied gas is improved accordingly.
