Description

(54) HEAT BATTERY

I

The invention relates to the field of solar technology and can be used to accumulate heat in solar heating systems.

A heat accumulator is known, comprising a housing with inlet and outlet nozzles for charging and discharging, the discharge nozzle of charging is located in the lower part of the housing, and the air inlet pipes are located in the upper part of the latter,

The height distribution of the heat transfer medium entering the specified battery is determined by its temperature, temperature conditions in the battery, the geometry of the partitions located in the housing, as well as the speed of the heat transfer medium at the battery inlet.

The disadvantages of this battery are caused by the fact that, due to the openness of the compartments formed by partitions, the incoming heated heat carrier is mixed, which, when lifted, partially gives off heat to the environment, and consequently reduces its

temperature does not reach the height of the level corresponding to its initial temperature at the entrance to the battery.

At the same time, the stratification conditions in the battery deteriorate and its diode capacity decreases, and the thermal characteristics of the battery deteriorate.

As a result, a significant number of stratifying factors also makes it very difficult to calculate the required geometric shape and size of partitions, the distribution of the heat carrier along the height, depending on its temperature,

The purpose of the invention is to improve the thermal characteristics of a battery by automatically supplying the heated heat carrier to the required height, depending on its temperature.

Claims (2)

The goal is achieved by the fact that the battery additionally contains a feeding chamber located inside the housing, connected by an inlet to the charge charging inlet through a flexible hose and provided with a check valve at the outlet. KaMepte is supplied with a non-perforated partition inside otvakumuroyroyshyy. W FIG. 1 shows a battery in the absence of a supply of coolant; FIG. 2 - the same, when the coolant is supplied with a temperature exceeding the temperature of the heat accumulated medium in the battery; FIG. Figure 3 shows a nutritional chamber containing perforation, a septum; FIG. 4 shows a heat accumulator with a feed chamber containing a check valve and a hermetic cavity; FIG. 5 - section aa of FIG. 4. FIG. 6 shows the option of mounting the feeding chamber. The heat accumulator contains a housing 1 with inlet and outlet connections 2 and 3 for charging and 4 and 5 discharge, with the discharge connection for charging 3 located in the lower part of housing 1, and pav 4 of 5 discharge in the upper part last one. The battery further comprises a feeding chamber 6 located inside the housing 1, connected by an input to the inlet 2 to charge the intermediate flexible hose 7 and provided with an outlet check valve at the outlet and 8. The feeding chamber 6 is provided with an perforated partition 9 located inside it and equipped with an airtight container 1O filled with air or otiacuomatised. The battery contains guide posts 11 mounted vert: crazy inside the case. The rings 12 are attached to the feed chamber 6 and are put on the pillars 11. The flax feed chamber may contain a counter 13, connected to it by a cable 14, thrown over the pulleys 15, mounted on the racks 11 (Fig. B). The heat accumulator operates as follows. Before starting the operation, the heat accumulator is discharged, the supply of the heated coolant is absent; the temperature of the coolant filling the feeding chamber 6 is equal to the temperature of the heat storage medium, the check valve 8 is closed. The nourishing chamber 6 at the same time occupies the lowest position in the corus. When the heated coolant is supplied through the pipe 2, the flexible hose 7 into the feed chamber 6, the check valve opens under the pressure of the heating medium, and the cold heat carrier is displaced from the feed chamber 6 into the housing 1, the cold heat carrier through the pipe 3 is heated by the heat carrier, the backup chamber starts under the influence of the emerging buoyancy force, move upwards. The dimensions of the feeding chamber are chosen in such a way that its weight, with its heat transfer medium, is less than the size of the heat storage medium transported by the chamber. Since, at the initial moment, the temperature of the thermally accumulated medium throughout the whole volume, the feeding chamber b rises into the uppermost part of housing 1, and the heated heating medium goes up the accumulator and goes through the branch pipe 4 to the heating needs, and the spent heating medium returns to the accumulator pipe 5. As a result of the simultaneously occurring processes of discharge and charging of the battery, temperature separation occurs in the battery through the height of the housing 1. When the temperature changes of the heat carrier entering the nutrient chamber 6, it will be mixed in height to the level at which the temperature of the heat-accumulating medium will be equal to the temperature of the heat-transfer fluid leaving the feed chamber 6, with each temperature value of the heat-exchanging fluid exiting chamber 6, will correspond to a certain height at which the coolant will flow into the housing 1, the feeding chamber b will be at this height until the temperature of the incoming coolant changes, i.e. eye nutrient chamber filled with weight b yuYu11; they will be equal to its coolant weight augoy it displaces part of heat storage medium. When the supply of coolant through the pipe 2 stops, the valve 8 closes and the reverse circulation through the feed chamber 6 turns out to be impossible, in whatever position it is located. This eliminates the loss of heat from the battery and ensures its diode. In order to eliminate the influence of the weight and size of the feeding chamber itself on its movement depending on the temperature of Tjpbt, it can be performed with opposite J, equal in weight and connected to it by a flexible cable 14, thrown over the pulleys 15, attached to vertical racks 11 installed inside the housing 1 of the battery. Thus, in a heat accumulator, thermal characteristics are improved by supplying the heated coolant to a height determined by the conditions of stratification in it. 1.
