1. A liquefied fluid supply system of supplying a nozzle with a liquefied fluid that vaporizes after spraying, the liquefied fluid supply system comprising:
a supercooler that cools the liquefied fluid to a temperature lower than a saturation temperature thereof and makes the liquefied fluid into a supercooled liquid; and
a booster that boosts in pressure the liquefied fluid made into the supercooled liquid by the supercooler and supplies the liquefied fluid to the nozzle,
wherein the supercooler includes
a supercooler heat exchanger that cools the liquefied fluid to be supplied to the booster by heat exchange with a cooling liquefied fluid having a temperature lower than that of the liquefied fluid,
a discharge pipe connected to a storage tank that stores the liquefied fluid,
a booster supply pipe that connects the supercooler heat exchanger and the discharge pipe to each other and guides, to the supercooler heat exchanger, the liquefied fluid to be supplied to the booster,
a cooling pipe that connects the supercooler heat exchanger and the discharge pipe to each other and guides the liquefied fluid as the cooling liquefied fluid from the discharge pipe to the supercooler heat exchanger, and
a cooling pipe orifice provided in an intermediate portion of the cooling pipe that provides resistance to the flow of the cooling liquefied fluid.
