The present invention relates to a trigeneration energy supply system having improved cooling and system use efficiency. The trigeneration energy supply system according to one embodiment of the present invention can comprise: a vacuum pump; a vacuum chamber inside which a vacuum is created by the vacuum pump; a condensed water storage tank positioned higher than the vacuum chamber, and prepared so as to store condensed water formed when steam generated by evaporating water brought inside the vacuum chamber is transferred to the inside of the tank by the vacuum pump; a cooling pipeline arranged to pass through the inside of the vacuum chamber cooled during the water evaporation and prepared to deliver cool air to a cooling load; and a small hydroelectric power generation system for generating electrical power by allowing the condensed water stored in the condensed water storage tank to be poured from at least the height of the condensed water storage tank.

A linear power generator has a gas pressure cylinder structure which causes reciprocating motion of a piston in an axial direction by supplying a high-pressure gas alternately to a left gas chamber and a right gas chamber of a cylinder which includes an electromotive coil, and alternately applying a gas pressure in the left gas chamber and a gas pressure in the right gas chamber to the piston which includes a permanent magnet in the cylinder, and which induces power generation of the electromotive coil by way of reciprocating motion of the piston which has the permanent magnet in the axial direction. The linear power generator encourages movement of the piston by supplying a first high-pressure gas into the left gas chamber and the right gas chamber, and keeps moving the piston by supplying a second high-pressure gas for supplementing the first high-pressure gas into the left gas chamber and the right gas chamber.
