Abstract

The invention makes it possible to regulate the temperature regime of the heat transfer medium in the collector by changing the active capacity and the heat radiating surface of the battery. The collector contains a transparent coating 5, an absorber 6 and a heat accumulator in the form of separate sections 7. The latter are placed behind the absorber 6 with a pitch from each other and arranged to move up to contact with each other and with the absorber 6. For circulation of the coolant in the collector, an inlet 2 and outlet 3 holes. When the coolant overheats, part of the solar radiation begins to accumulate in the heat accumulator, and when the coolant cools, the stored energy from the accumulator is returned. The capacity of the heat accumulator is regulated by the number of sections 6 in contact with each other and with the absorber. 3 Il.

The invention relates to solar technology, namely to the field of solar collectors f about means of accumulating solar radiation.

The purpose of the invention is to provide a set temperature mode of the heat carrier due to a change in the active capacity of the heat accumulator,

Figure 1 shows the solar count Lecturer, meridional section; FIG. 2-yhema of the solar collector operation in charge mode; fig. 3 - the same, in the mode of discharging a heat accumulator.

The solar collector contains a housing 1 with an inlet 2 and an outlet 3 for the circulation of heat carrier 4 and a transparent coating 5. The absorber 6 and the (heat accumulator) are installed parallel to the coating 5 in the case. (The last battery is made of heat-absorbing sections 7 parallel to the absorber 6 installed with the ability to move up to sopro- ((base between themselves and with the absorber 6. The collector works as follows.

The sun's rays 8, penetrate through the rotary coating 5, fall on the absorber and heat it. The coolant 4, directed by convection of radiant energy t of the absorber b, rises and leaves the outlet 3, and in its place cold coolant 4 enters through the inlet 2. If the coolant 4 heats up above the allowable temperature, the sections 7, the heat accumulator is moved to contact with each other and the absorber 6. As a result, some of the heat energy is transferred from the absorber 6 and stored in the heat accumulator.

The amount of heat withdrawn and stored by the battery is regulated by the number of heat-absorbing sections 7 involved. This maintains the temperature of the heat transfer medium within acceptable limits during the period when solar radiation reaches the collector

When the temperature of the coolant of the heat accumulator section 7 decreases, they are alternately disconnected and moved to the initial position (Fig. 3). The consequence of this is an increase in the heat-emitting surface and an increase in the heating intensity of the heat transfer medium, since the latter absorbs heat not only from the absorber, but also from sections 7 of the battery, spreading in the channels between sections 7.

The collector operation is controlled by varying the active capacity and the heat radiating surface area of the battery, thus avoiding overheating or underheating of the coolant without heat loss in the collector.
