PURPOSE: A system for supplying a natural gas fuel is provided to manufacture a small heat exchanger by improving heat exchange efficiency by heat-exchanging with an engine heat which is a relatively high temperature comparing with seawater. CONSTITUTION: A system for supplying a natural gas fuel comprises a fuel supply line (100), a vaporizer (210) and a heater (310), a first refrigerant circulating line (200), a second refrigerant circulating line, and an engine heat transfer line (500). The fuel supply line supplies a fuel to a used place from a natural gas storage tank (1). The vaporizer and the heater are successively installed at the fuel supply line. The first refrigerant circulating line is connected to the vaporizer, and an air handling unit (220) is installed. The second refrigerant circulating line is connected to the heater, and a heat exchanger (510) is installed. The engine heat transfer line is connected to the heat exchanger. |
