Abstract: The purpose of the present invention is to provide a trigeneration system using dimethyl ether (DME), wherein the system produces electricity, controls heating and cooling, and supplies carbon dioxide as a fertilizer by driving a DME engine by using, as a raw material, DME which is clean fuel. A trigeneration system using DME according to the present invention may comprise: a DME tank in which DME fuel is stored; a DME engine driven by means of the DME fuel as a raw material; a DME fuel supply unit for supplying the DME fuel stored in the DME tank to the DME engine; a treatment unit connected to an exhaust line for discharging exhaust gas from the DME engine, so as to treat harmful components of the exhaust gas; a power generation unit for producing electricity by means of a driving force of the DME engine; and a cooling and heating unit for supplying or collecting heat by means of the driving force of the DME engine.
