Energy-saving air conditioning device

The invention discloses an energy-saving air conditioning device. The energy-saving air conditioning device comprises a shell body, a semiconductor refrigeration sheet, an energy storage box, a storage battery, a power supply for charging the storage battery and a solar battery, wherein the shell body is provided with a sliding rail; sliding wheels are arranged at the bottom of the energy storage box; the sliding wheels are matched with the sliding rail; the energy storage box comprises a cold storage box and a heat storage box; a first through hole and a second through hole are formed in the bottoms of the cold storage box and the heat storage box respectively; a first thermoelectric generator and a second thermoelectric generator are clamped in the first through hole and the second through hole respectively; a hydraulic cylinder is arranged at one side of the energy storage box; a piston rod of the hydraulic cylinder is connected with the cold storage box; a first temperature sensor, the hydraulic cylinder and the storage battery are connected in series. According to the energy-saving air conditioning device disclosed by the invention, one face, which is not utilized, of the semiconductor refrigeration sheet is sensed through the first temperature sensor; the hydraulic cylinder is controlled to push the energy storage box to collect energy of the face which is not utilized; the thermoelectric generators can be used for converting the energy into electric energy for continually refrigerating or heating, so that the power utilization amount of the air conditioning device is greatly saved and the environment is protected.
