LATENT HEAT UTILIZING HEAT STORAGE DEVICE

摘要

PURPOSE:To provide a device in which the temperature of a medium is constantly and suitably controlled in conformity with a predetermined heat using condition and which is controlled easily and simply by detecting an actual temperature of a heat transfer medium extering into a heat exchanger on the side of a heat using apparatus at the time of a heat radiation mode and operating the flow quantity of the medium passing through a heat storage tank as an operating signal therefor. CONSTITUTION:In a case where an actually detected temperature (t) of a heat transfer medium, at a position 15 on this side of a heat exchanger 3 exceeds a control target set temperature T, a flow quantity control valve 3 is controlled of its opening degree using a deviation DELTAt as an operating signal at the time of a heat radiation so that a part of the medium leaving the heat exchanger 3 via a bypass pipe 13. The ratio between the diameter D of the heat storage tank 7 and the full length L corresponding to the horizontal length is determined in a range of 1:3-6 and in the sectioned tank inside 30 are closely accommodated small spherical heat storage bodies 29. Draining means 33 are formed on the lower part of a drum body 27 so as to permit the passage of the medium within a gap between heat storage bodies 27.
