PURPOSE: To obtain a heat storage apparatus which stably extracts heat from a heat storage tank at a high level, without a decrease in the quantity of heat extracted therefrom even when the temperature of the heat reservoir changes and which is free from local corrosion in the heat-transfer tube in a regenerator. ;CONSTITUTION: A heat storage cooling/heating apparatus is equipped with an absorption refrigerator 2 for effecting cooling and/or heating and a heat storage tank 1 for storing thermal energy used for the power source of the refrigerating machine; the heat storage tank 1 is filled with a heat storage material and has an electric heater 22 and a heat-transfer tube 21 inside; the thermal energy is supplied to the absorption refrigerator 2 by using as the heat medium passed through the heat-transfer tube 21 a fluid whose phase changes between vapor and liquid. The heat-transfer tube 21 in the tank 1 is connected to a heat-transfer tube 24 in the generator 11 of the absorption refrigerator 2, which receives thermal energy from the tank 1, to form a closed circuit. In the line from the heat-transfer tube 24 of the generator to the heat-transfer tube 21 of the heat storage tank a flow-rate control valve 41 is provided. To this valve 41 a flow-rate control part 42 is connected in a setup to detect the temperatures at the outlet and inlet respectively of the heat-transfer tube 21 and to control the flow rate of the fluid so that the temperature at the outlet is higher than at the inlet.;COPYRIGHT: (C)1995,JPO
