FIELD: devices for heating of individual buildings used in regions where there are no central heating systems, or such a system is severely worn out and disabled.
SUBSTANCE: the device has a compression pump for pumping up water into the chamber - accumulator, pipe-lines for water delivery, set of parallel tubes with a low inside diameter for water delivery to the large-capacity chamber-heater at a high rate, providing for a slow passage of water and, due to it, flapping of cavitation bubbles and water heating, and a set of parallel-connected calorifers heated by this water for heating of rooms. The compression pump pumps up water into the accumulator at a pressure of 5 to 10 MPa, from which water at a rate of 90 to 100 m/s passes through 50 to 100 and more parallel tubes with an inside diameter of 5 to 10 mm and comes to the chamber-heater, where the cavitation bubbles are flapped at a pressure of 5 to 10 MPa and heat the water to a temperature of 100 to 150 C and higher. Then the water comes to the calorifers, and from the calorifers to the heat exchanger heating the water for the domestic needs. Then, the cooled water comes to the compression pump again thus completing the working cycle.
EFFECT: enhanced efficiency of the heating system operation of the basis of the experimental results, enhanced reliability of system operation.
