PROBLEM TO BE SOLVED: To provide a heat storage device for reducing working electric energy by increasing a cold amount (energy consuming efficiency) to be stored with the same electric energy, and to provide an air conditioning system using the same. SOLUTION: The heat storage device comprises an upper latent heat storage part (an upper latent heat storage member 13) provided on the upper layer of a heat storage tank 12, a lower latent heat storage part (a lower latent heat storage member 14) provided on the lower part of the heat storage tank 12, the lower latent heat storage part (the lower latent heat storage member 14) having a phase transfer temperature set to be lower than the phase transfer temperature of the upper latent heat storage part (the upper latent heat storage member 13), a cooling upper heat exchanger 38 installed on the upper part of the heat storage tank 12, and a heating lower heat exchanger 42 installed on the lower part of the heat storage tank 12, the heat storage tank 12 having a cavity filled with heat storage fluid. The air conditioning system using the same supplies fluid in the upper layer of the heat storage tank 12 directly from an upper fluid access or heat in the upper layer via the fluid in the heat exchanger to an air-conditioner during heating, and supplies fluid in the lower layer of the heat storage tank 12 directly from a lower fluid access or heat in the lower layer via the fluid in the heat exchanger to the air-conditioner during cooling.
