Description

112

The invention relates to a power system, namely to heat supply, and can be used in hot water supply systems.

The aim of the invention is to increase the economy by reducing hydraulic losses and intensifying heat exchange,

The drawing shows the proposed system.

The hot water supply system contains an inlet manifold 1, connected in parallel through lines 2, 3 and 4, respectively, of cold, warm and hot water and the corresponding water collecting pipes 5, 6 and 7 to the water intake 8 and mixing and water 9 fittings, let’s The hot and hot water sinks 6 and 7 are connected by ring bridges 10, the hot water main 4 is supplied in series with the heaters 12 and 13 of the first and second stages in the zone 14 between the last and valve 11 connected to the valve through the return valve 11 The connecting pipe 15 of the pump 16, and the hot water pipe 3 is equipped with a check valve 17 and connected behind the latter to the suction pipe 18 of the pump 16 and the bypass pipe 19 with the warm water temperature regulator 20 “The system also contains a battery 21 with an inlet and an outlet pipe pipelines 22 and 23, the first of which is equipped with a temperature controller 24, as well as a parallel bypass line 25 with a throttle diaphragm 26, and connected to the inlet manifold .J, and the output pipe 23 of the battery 21 is connected to the trunk 4 Op hot water heater 13 after the second stage and with nym bypass line 19, provided with an automatic shut-off device 27.

The hot water supply system works as follows.

In the absence of water pumping, the pump 16 operates and the system circulates water through the ring — the heater of the second stage 13 — the main line 4 — the stand 6 — the ring jumpers 10 — the stand 7 — the main line 3 the pump 16, and also the battery charge 21 along the ring - the heater 13 of the second stage - the pipeline 23, the battery 21 - the pipeline 22 with the temperature controller 24 - the pipeline 3 - the pump 16. At the same time, the locking device 27 of the pipeline 19 is closed. When filling the battery

21, with hot water, temperature controller 24 blocks the circulation in the charge ring, which prevents heat flow to the heat carrier of the first stage of the heater 12. When switched on

shutdown of the pump 16, the shut-off device 27 and the regulator 20 of the pipeline 19 open up, water flows from the inlet manifold 1 to the heaters 12 and 13 of the line 4 and with a temperature of 55-60 ° C and 6 to the fixture 9, and from the accumulator 21 mountains Water with a temperature of 55-60 C enters through pipelines 23 and 19 into line 3, where

mixed with cold water and with a temperature of 30-35 ° C enters through valve 7 to valve 9. At maximum drainage, the battery 21 is completely discharged through pipeline 23 to trunk 4 and pipeline 19 with the valve completely open 3

The use of the proposed hot water supply system makes it possible to further reduce the surface of the preheaters and the loss of pressure in them by 20–30%, as well as to reduce the temperature of the water entering the heating system at minimum water consumption.
