System and method for making ice

A system for making water, comprising:

• a compressor;
• a condenser for allowing a refrigerant having passed through the compressor to flow in the condenser;
• an expansion unit for expanding a refrigerant having passed through the condenser into a refrigerant of relatively low temperature and low pressure;
• an ice-making pipe for allowing at least a portion of a refrigerant having passed through the expansion unit to flow in the ice-making pipe, the ice-making pipe being curved or bent several times to form a plurality of protrusions;
• a heating member provided on surfaces of the protrusions;
• and
• a tray for allowing the protrusions to be positioned in the tray, the tray containing water to be used for making ice and being rotated when ice is completely made.

A method for making ice, comprising the steps of:

• storing water to be used for making ice in a tray;
• forming ice on a surface of a refrigerant pipe by causing a refrigerant of relatively low temperature to flow in an ice-making pipe;
• rotating the tray to remove remaining water;
• and
• releasing the formed ice from the ice-making pipe.
