Abstract
PURPOSE:To make it unnecessary to make uneven temperature uniform in a heat accumulating tank and keep it from having an energy loss by setting a plurality of temperature sensing points in the heat accumulating tank and obtaining the integrated value or the rate of change of the accumulated heat quantity of a medium in the tank. CONSTITUTION:Temperature sensors a-k are provided with a certain distance among them in a medium in a heat accumulating tank 14 in the direction of its height, and each detected value is outputted to a measuring instrument 26. The measuring instrument 26 calculates the accumulated heat quantity by a formula (I) based on the respective detected values of the temperature sensors a-k. In the formula (I) T is a base temperature of the medium, Ta-k is the temperature of the medium when a heat generator takes in the medium of temperature T and a necessary temperature difference was given (namely the energy level is raised relatively than T), that is, the temperatures detected by the temperature sensors a-k, Va-k is the volume of the medium which the medium occupies among respective temperature sensors, K is a constant (specific weight, specific heat, etc. are made constants), and Qa-k is the effective retained heat (accumulated heat) quantity which corresponds to the above Va-k. Incidentally it is also possible to know the rate of change by calculating the time in which the accumulated heat quantity is increased or decreased for each step among the temperature sensors.
