The invention relates to the field of energy storage and discloses a combined cooling, heating and power compressed-air energy storage system. In the energy storage mode, according to the system, electric energy is consumed by the aid of a compressor set, compressed air is stored in an air storage device, and heat produced in the compression process is recovered by the aid of a cooler and is stored in a heat storage device; in an energy releasing mode, according to the system, the air in the air storage device is heated by the aid of a regenerator, a turbine generator set is driven by the hotair to generate power, and cold produced in the expansion process is stored in a cold storage device; in the heating mode, according to the system, heat is supplied to the outside of the system by theaid of the heat storage device; and in the cooling mode, according to the system, cold is supplied to the outside of the system by the aid of the cold storage device. The system can run in the singlemode or run in a multiple-mode-mixed manner. Meanwhile, the system can recover heat sources such as industrial waste heat, waste heat, solar energy and the like by the aid of a preheater or the heatstorage device, or the system can recover the cold such as industrial waste cold, LNG gasification and the like by the aid of an after-cooler or the cold storage device, and the simple system is usedfor meeting the diversified energy requirements.
