Abstract

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.

First claim

What is claimed is:

1. A trigeneration energy supply system comprising:
a vacuum pump;
a vacuum chamber in which a vacuum is formed by the vacuum pump;
a condensate water storage tank located above the vacuum chamber and provided to store condensate water formed by transferring vapor formed by evaporating water which flows into the vacuum chamber to an inside by the vacuum pump;
a cooling pipe disposed to pass through an inside of the vacuum chamber cooled while the water is evaporated and provided to transfer cold air produced through thermal exchange to a cooling load; a second vacuum pump different from the vacuum pump;
a second vacuum chamber located above the vacuum chamber;
a second condensate water storage tank located above the second vacuum chamber;
a second cooling pipe disposed to pass through an inside of the second vacuum chamber cooled while the water is evaporated and provided to transfer cold air produced through thermal exchange to the cooling load;
an evaporating pipe which connects the condensate water storage tank with the second vacuum chamber; and
a small hydro power generation system which generates power by dropping condensate stored in the second condensate water storage tank from at least a height of the second condensate water storage tank.

2. The trigeneration energy supply system of claim 1 , wherein the small hydro power generation system comprises a small hydro power generation water storage tank located at a top level of a building, and
wherein the small hydro power generation water storage tank stores the condensate water.

3. The trigeneration energy supply system of claim 2 , wherein the small hydro power generation system further comprises a circulation pump provided to transfer the condensate water of the second condensate water storage tank located below the small hydro power generation water storage tank to the small hydro power generation water storage tank.

4. The trigeneration energy supply system of claim 1 , wherein no additional pump is installed at the evaporating pipe and the condensate water is transferred from the condensate water storage tank to the second vacuum chamber due to a pressure difference between the condensate water storage tank and the second vacuum chamber.

5. The trigeneration energy supply system of claim 1 , wherein the small hydro power generation system comprises a circulation pump and a small hydro power generation water storage tank, to which condensate water stored in the second condensate water storage tank is transferred by the circulation pump, the small hydro power generation water storage tank located above the second condensate water storage tank.
