The invention discloses a triple generation system. A gas motor, an afterheat furnace and a lithium boride refrigerator are adopted to form an energy center; the energy center performs the energy supply outputting of heat supply or cold supply to a transduction station through a pipe, and supplies electricity to each mechanism of the transduction station; the transduction station serves as a heatexchange place between the energy center and an user terminal; a temperature control RTU module of the transduction station can monitor present energy supply conditions, and can control equipment of the energy center, so that skills of each equipment are operated in a safe and stable range; and the energy consumption of each equipment is counted, so that the energy use efficiency is optimized.
