Description

 The invention relates to a power system, heat engineering and is intended for heat supply and heating of residential, administrative, agricultural, industrial buildings and their individual premises using failed electricity and electricity from non-traditional sources.

 Known electric heat accumulator / I / for individual use, used for heat supply and heating of individual rooms.

Known battery / 2 /, which contains:
solid state storage material consisting of blocks,
electric heating elements
insulated housing
heat conducting element.

 In the lower part of the body are openings for air inlet. In the upper part of the body is a volume for heated air. In the upper part of the housing are openings for the exit of heated air. Between the side walls of the heat-insulated casing and the heat-conducting elements there are vertical channels for the passage of air heated in them.

A disadvantage of the known device is the exit of hot air in its upper part, because at the same time / as noted above / the layer of air in the room is heated from floor to top ETA
Known is an electric heat accumulator containing a thermally insulated body, provided with an air inlet at the bottom and a regulating body, a heat storage nozzle with heaters and with vertical channels in it for the passage of heated air, as well as an additional thermally insulated unheated vertical channel for lowering air movement, placed outside case and connected in the upper part with a channel for heated air in the nozzle, and in the lower end equipped with an outlet pipe / 3 /.

 The disadvantage of this battery is the inability to work on the basis of the free convective movement of the heated air.

 The aim of the present invention is to provide heating of the air in a heated room not only above the battery, which does not have a fan assembly, but also in the air layer between the floor and the top of the battery.

 The invention is illustrated in the figure, which shows a General view of the battery.

 The device consists of a solid-state accumulating material 1, electric heating elements 2, a heat-insulating shell of the housing 3, a heat-insulating substrate of the housing 4, vertical channels 5 located between the blocks of the accumulating material, dampers 5 with a regulating mechanism, a channel 7 for lowering the movement of heated air provided with an external fin 8 to increase heat transfer to the heated room, the shutter 9, equipped with fins, adjustable shutter 10, which serves to dispense the flow of heated air and through the battery, the choke knob 10 November.

 The proposed device operates as follows.

 The air heated in the vertical channels 5 due to the lifting force of Archimedes moves up in them / free-convection movement /. Moving heated air passes the adjustable damper 10, bypassing the closed damper 9, and descends down the channel 7, losing some of the heat through the outer fin surface 8 of the channel 7, and enters the heated room through the protective grill at the bottom of the battery. The movement of air is shown by arrows 12. From the moment when the driving pressure in hot air begins to be insufficient for the downward movement of air, a shutter 9 opens, which continues to be open until the pressure in the hot air rises to a sufficient value for the downward movement in channel 7.

The lifting and lowering movement of air heated in the vertical channels 5 is possible subject to the following conditions. The lifting force in the air flow of the vertical channels 5 is greater than or equal to the sum of the forces, which is the lifting force of the air in the channel 7, plus the friction forces in the channels 5 and 7 and plus the friction forces arising from the local resistance / damper 10, 90 ^° turns, protective grill, battery input and output. The damper 9 is open when the air in the channels 5 is not sufficiently warmed up / i.e. ETA is not yet sufficiently charged or is already very discharged. The condition for the lifting and lowering air movement in ETA will be satisfied, i.e. the air in channel 7 is cooled.

 Thus, the proposed device, lacking a ventilation unit, provides heating of the heated room air not only above the battery, but also between the floor and the top of the battery. In addition, the proposed device by controlling the flow of hot air by the shutter 10 and the regulator 11 is able to provide, under the conditions of the calculated operating mode, the constancy of the heat dissipation power in the heated room.
