Heat storage device with a closed water circulation system

Abstract

The subject of the application is a heat storage device with a closed water circuit comprising a thermally insulated two-chamber water tank (1) in the form of a vertically oriented cylinder or a right prism, in which there is a horizontally arranged, rigid, thermally insulating movable partition (2) mounted on guides, sealed against the side walls and vertically movable, dividing the water tank (1) into a lower cold water chamber (A) and an upper hot water chamber (B). In addition to the water tank (1), the lower chilled water chamber (A) is connected to the upper hot water chamber (B) via a circulating pump (3) and a water heater (4). A water supply pipe is connected to the lower chilled water chamber (A), and a discharge pump (5) is connected to the upper hot water chamber (B) via a discharge pipe.Temperature sensors (6.1, 6.2) are located in the pipe supplying water to the lower chilled water chamber (A) and in the pipe draining water from the upper hot water chamber (B). The circulation pump (3), drain pump (5), and temperature sensors (6.1, 6.2) are connected to the controller (7). It is characterized by a fixed partition (8) with an adjustable deflector (9) in the upper hot water chamber (B). The drain pump (5) is connected through the upper wall of the water tank (1) to a telescopic tube, at the end of which a float (10) is mounted. The drain pump (5) is connected through a heat exchanger (11) to the pipe supplying water to the lower chilled water chamber (A). The heat exchanger (11) is connected to the heat transfer medium pump (12). A position sensor (13) of the movable partition (2) is located in the movable partition (2).The adjustable deflector (9) and the heat receiving medium pump (12) and the position sensor (13) of the movable partition (2) are connected to the controller (7).
