According to an embodiment of the present invention, a cold heat utilizing method using a cold heat system exchanges heat with fuel supplied to a source of demand from a liquefied gas storage tank, and includes a PCM cold heat storage tank for storing a phase change material whose phase is changed to store cold heat of the fuel, and a cold heat supply line connected to a cold heat receiving device from the PCM cold heat storage tank so as to supply cold heat, and the method comprises: a step of measuring an amount of cold heat stored in the PCM cold heat storage tank; a step of measuring a required amount of the cold heat per apparatus; a step of calculating an amount of the cold heat which should be transferred from the PCM cold heat storage tank to each of the apparatuses; and a step of transferring the cold heat in the PCM cold heat storage tank to each of the apparatuses. According to the cold heat utilizing method in accordance with the present invention, when cryogenic liquefied gas is heated to be used as fuel, cold heat discharged from the liquefied gas is stored in a phase change material and used for cold thermal energy of an air conditioning unit or cooling a heating element, immediately or at intervals. Accordingly, energy can be saved because the cold heat is utilized rather than discarded. In addition, output of cold heat required from the air conditioning unit and the heating device can be reduced, thereby minimizing energy required for driving a vessel or an offshore plant.
