INVENTION
Russian Federation Patent RU2096691
INSTALLATION FOR HOT WATER
Name of the inventor: Nedorezkov Paul Maksimovic
The name of the patentee: Nedorezkov Paul Maksimovic
Address for correspondence:
Starting date of the patent: 1995.08.03
Use: industrial and domestic hot water systems. The inventive installation comprises electric pumps, heat generator jet action, remote system control, piping with valves and tank-extender. In addition, it further comprises a cascade jet heat generators in series connected at the input with a water-jet elevator, and output - with the annulus of the heat exchanger having a partial selection heated water after each stage of the cascade, implemented waterjet elevator, but also the heat exchanger, which shell space inlet connected to the outlet of the heated water cascade, and the output of the annulus of the heat exchanger with the suction pump and the electric pump installation expander tank and pipe heat exchanger inlet space is connected to the cold water supply conduit, and the output - to the consumer through the network control device.
DESCRIPTION OF THE INVENTION
The present invention relates to a power system and can be used in industrial and domestic hot water systems.
Known invention "autonomous hot water system" [1]
The disadvantages of this invention is the complexity and bulkiness of the system, which requires a large area to accommodate large and communication.
Known and installation of hot water for space heating, which contains the electric pump unit, heat source of the jet action, piping, expansion tank and control panel heated water [2]
Said unit can be used both for heating and for hot water. It we take as a prototype.
The disadvantage of this system is that it contains one electropump one heat source unit and the jet action, which is not able to convert highly effective liquid jet kinetic energy into heat.
The proposed plant for producing hot water increases the efficiency of converting the kinetic energy of the jet of fluid into thermal energy by unit of the cascade jet heat generators connected in series, and a water-jet elevator, providing a predetermined pressure drop after each stage of the cascade.

The essence of the invention is as follows. Installation includes electric pump units, heat generator jet action, remote system control, piping with stop valves, expander tank. In addition, it further comprises a stage of heat generators, connected in series, having a partial selection heated water after each stage of the cascade, waterjet elevator implemented. Water-jet elevator works on centrifugal pump jet energy, which is connected to suction bakom- expander and injection coupled with a supply of water-jet elevator, feed partially heated water back into the cascade. This ensures that the pressure drop across each stage of the cascade and heated water in a closed loop to a predetermined temperature, and heating the water supplied to the consumer, is carried out in the heat exchanger. As water intake regulators from each stage of the cascade can be used chokes, valves and other regulating means. The invention is illustrated by a drawing, in which: electric pump unit 1, the control unit 2 electric pump unit 1, the intake pipe 3 of the electric pump 1, the injection nozzle 4 of the electric pump 1, a bypass line 5 with the valves 6 and 7, a supply conduit 8 to a water-jet elevator 9, valve 10 on discharge electric pump 1, a cascade of jet heat generators 11, a partial selection of the water pipeline 12 with the regulators 13. piping hot water 14 into the annulus of the heat exchanger 15, pipe 16 at the outlet of the heat exchanger annulus 15. The pipeline 17 on the expansion tank 18, the water level controller 19 the expansion tank 18, supply pipe heated water 20, to the tube space of heat exchanger 15. The pipeline system feeding 21 hot water pipeline to the consumer 22 with a tap 23. The hot water thermostat 24, the cable 25 from the thermostat 24 to the control unit 2 electric pump unit 1. |
INSTALLATION FOR HOT WATER WORKS AS FOLLOWS
All the valves are open, except for the tap 24. Filling the water installation is made through the expansion vessel 18 to establish the required level. After filling the system close the valves 6 and 7 on the bypass line 5. Start the electric pump unit to work 1 and pumping water through a cascade of heat sources 11 and annulus of the heat exchanger 15.
To pump the water to the establishment of a stable mode of operation of the electric pump unit 1. Then open the valves 6 and 7 on the bypass line 5 and thus launch the work of the water-jet elevator 9. Close the valve 10, and outputs a stable operation Waterjet elevator 9. Next, the pressure loss adjustment after each stage 11 stage 13 by means of regulators.
Thus, we conclude the installation work at the optimal mode. Then we provide the water heated to a predetermined temperature by the temperature sensor 23, the consumer, the spigot 24.
The proposed plant for producing hot water has the following technical and economic advantages.
1. Increases the efficiency of conversion of the kinetic energy of the jet of fluid into thermal energy.
2. Reduces the cost of capital investments.
3. Allows you to exercise with less choice of equipment for a variety of hot water supply needs.
CLAIM
1. An apparatus for manufacturing hot water containing electric pump units, heat generator jet action, remote system control, piping with stop valves, tank-extender, characterized in that it further comprises a cascade of heat sources connected in series, connected to the inlet to the water-jet elevator, and output from the annulus of the heat exchanger having a partial selection of heated water after each stage of the cascade, carried out water-jet elevator working on the centrifugal pump energy of the jet, suction is connected to the expander tank and pumping with a supply of water-jet elevator, which feeds partly heated water again cascade, thereby enabling the pressure drop across each stage of the cascade in a closed loop to a predetermined temperature, and a heat exchanger annulus which is connected at the inlet to the outlet of the cascade of heated water, and the output of the annulus of the heat exchanger with the suction pump electric pump installation and a tank -expander and tube side of the heat exchanger at the inlet to the cold water supply conduit and the outlet from the consumer through the network control means.
2. Apparatus according to claim 1, characterized in that as a water intake regulator from each stage of the cascade may be chokes, valves and other regulating means.
