Zusammenfassung: | The present invention relates to a liquefied hydrogen charging system to maximize energy efficiency. According to the present invention, a cold heat recovery-type liquefied hydrogen charging system is a liquefied hydrogen charging system vaporizing hydrogen in a storage tank where liquefied hydrogen is stored and supplying the hydrogen to a charger. According to the present invention, the liquefied hydrogen charging system comprises: a vaporizer connected to a storage tank to vaporize liquefied hydrogen; a heat exchanger connected to the rear end of the vaporizer to increase the temperature of gaseous hydrogen; a compressor connected to the rear end of the heat exchanger to compress the heated gaseous hydrogen; a rear-stage cooler installed at the rear of the compressor to cool and supply the gaseous hydrogen to a charger; a first circulation line supplying cold heat exchanged in the heat exchanger to a refrigerant cooling the gaseous hydrogen in the rear-stage cooler; and a second circulation line transferring heat at a predetermined temperature to the heat exchanger.
