Abstract

The invention relates to heat supply systems and improves reliability by reducing heat loss in the consumer circuit. The hot water supply system contains a reverse 1 and 2 supply pipelines, an elevator 3 installed on the latter, to the entrance of which a return pipeline 1 is connected, heaters of the upper 4 and lower 5 stages of water conductivity, flow controller 6 connected to the entrance of the elevator 3, sensor 7 , 8 temperatures, installed on the return pipeline 1 and the pipeline 10 of the heated tap water, the water distribution unit 9 of hot water, installed on the pipe 10 after the preheater 4 upper stages. After preheater 4, a pipe in pipe heat exchanger 11 is installed, the internal cavity of which is connected to the heated water pipeline 10 and the water dispensing unit 9, and the external cavity to the outlet and inlet of the elevator 3. Using a pipe in pipe heat exchanger allows you to keep warm in one hundred hot tap water. 1 il.

The invention relates to heat supply systems, in particular to protective systems.

 The purpose of the invention is to increase reliability by reducing the heat loss in a customer's culture.

; The drawing shows the system of mountains of water supply, general, and view.

 The hot water supply system contains a return I and supply 2 pipeline, an elevator 3 installed at the last HJEM, to the input of which a return pipeline 1 is connected, heaters 4 and 5 in the upper and lower stages of the water supply, controller 6 flow with temperature sensors 7 and 8 and a water dispensing unit 9 of hot water installed in the pipeline 10 of the heated tap water after the preheater 4 of the upper stage. After the 4-stage preheater, a heat exchanger 11 of the “pipe in pipe” type is installed, the internal cavity of which is connected to the pipeline 10 of heated tap water and the collecting unit 9, and the external jjocTb - to the outlet and inlet of the elevator J, and the flow controller 6 is connected S to the inlet of the elevator 3, and the sensors 7 and 8 of the temperature are installed on the return pipeline and the pipeline 10 of the heated water-1 {1 conductive water. The return pipe 1 is connected to the elevator 3 via jumpers 12. The tap water is supplied from (source through pipe 13. The heat exchanger 11 is used as a towel warmer.

 The hot water supply system works as follows.

Water from supply 2 and return 1 pipelines is mixed in elevator 3. Mixed water enters the heater 4. The flow regulator 6 controls the amount of this mixed water depending on the temperature of the heated tap water and the temperature of the water behind the heater 4 sensors 7 and 8. If the amount is heating more water than necessary to heat tap water consumed by residents

Then, the temperature of the heated tap water and the temperature of the supply water behind the preheater 4 begin to rise. The flow regulator 6 will begin to decrease the capacity of the elevator 3 until this temperature returns to normal. The mixed water from the outlet of the elevator 3 also enters the circuit of the heat exchanger 11. The heated tap water flowing inside the heat exchanger 11 never cools even if the tap water is not consumed. Circulating water along the contour, mixed in the elevator 3 to 65 ° C, maintains tap water at a lower temperature (will not allow to cool), besides, the water passing through the circulation contour and jumper 12 heats the towel-driers day and night, regardless of the consumption of hot water. tap water.

The use of a heat exchanger of the type "pipe in pipe" allows to retain heat in the standpipe of heated tap water.
