A system and method for making ice is provided. The system may include a tray for containing a water to be used for making ice, and a refrigerant pipe positioned so that at least a portion thereof is submerged in the water contained in the tray. A refrigerant of relatively low temperature flows through the refrigerant pipe to cause ice to be formed on surfaces thereof. A heater may be provided on the refrigerant pipe and operated during an ice-releasing process. This system and method may eliminate the need for an additional duct to supply cold air to the ice maker, thus simplifying a manufacturing process and reducing manufacturing costs.
