PURPOSE: A method for producing steam using a vacuum pump, for obtaining high temperature using the produced steam, and for using the high temperature for desalination is provided to change low-grade heat into high-grade heat using low energy costs. CONSTITUTION: A method for producing steam using a vacuum pump, for obtaining high temperature using the produced steam, and for using the high temperature for desalination is as follows. A vacuum pump is attached on a vacuum heat exchanger. The vacuum pump discharges steam. External air heat, water heat, or waste heat is transferred to the vacuum heat exchanger, and the vacuum heat exchanger discharges low-temperature steam by operating a screw vacuum pump.
