    • PURPOSE: A regenerative heating and cooling device using midnight power service and method of the same are provided to heat and cool at inexpensive cost and to keep temperature of cooling water or heating water constant. CONSTITUTION: Heating water or cooling water in a cold and hot water storage tank(1) is heated by an electric heater(2) working by midnight power service and cooled down by a cooling device(3) as well. A temperature control tube(5) is installed between the cold and hot water storage tank and a cooling and heating piping(4). The cooling and heating piping is connected with the temperature control tube to send collected cooling and heating water to the cold and hot water storage tank by a first pump(6) or to the temperature control tube(5) by a second pump(7). A temperature controller(8) is installed on the temperature control tube near a point where cooling and heating water, supplied from the cold and hot water storage tank and collected after having circulated the cooling and heating piping, is mixed with cooling and heating water in the temperature control tube. The first pump and the second pump are operated by the temperature controller. The first pump is actuated and the second pump is not actuated when temperature detected by a temperature sensor(9) is lower/higher than the setup temperature on heating/cooling, respectively. The first pump is not actuated and the second pump is actuated when the temperature is higher/lower than the setup temperature on heating/cooling, respectively.
