LATENT HEAT UTILIZING HEAT STORAGE DEVICE

摘要

PURPOSE:To provide a device in which the temperature of a medium is fitted and controlled in conformity with a predetermined heat using condition and which is controlled easily and simply by detecting the actual temperature of a heat transfer medium entering 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 23 on this side of a heat exchanger 7 exceeds a control target set temperature T, a three-way control valve 22 is switched 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 7 is again returned to the heat exchanger 7 via a bypass pipe 21, and the flow quantity of the medium passing through the heat storage tank 8 is adjusted. The ratio between the diameter D of the heat storage tank 8 and the full length L corresponding to the horizontal length is determine in a range 1:3-6 and in the sectioned tank inside 36 are closely accommodated small spherical heat storage bodies 37. Draining means 41 are formed on the lower surface of a drum body 27 so as to permit the passage of the medium within a gap 42 between heat storage bodies 37.
