The implementation of the invention

A device for heating water using a high ambient temperature in the spring-summer period consists of a roof surface 1, which is a heat exchange surface, distribution pipes 2 mounted on the roof ridge (not numbered in Fig.) And having openings along the entire length of the drain pipes 3 of the inner rainwater gutter, water riser 4, water-water heat exchanger 5, receiving tank 6, thermotransformer 7, storage tank 8 located in the recess of the floor, while the receiving tank 6 contains town 9, the overflow pipe 10, the solenoid valve 11, and thermotransformer 7 comprises a heat exchanger 12 heat the water pipes 13 and 14 for circulating the aqueous solution pump binary mixture 15 connected to the water-water heat exchanger 5.

A device for heating water works as follows.

Before putting the thermotransformer 7 into operation, the internal cavity of the water-water heat exchanger 5 is filled with a binary mixture, for example, water with ammonia under pressure, and the storage tank 8 is filled with water, then the water from the storage tank 8 is pumped into the distribution pipes 2 installed on the roof ridge, through the holes in these pipes, water flows to the surface of the roof 1, on which it is heated by heat transfer through the surface of the roof 1, which has a high temperature, and when heated, enters the drain pipes 3 of the internal water and through the riser 4 to the water-water heat exchanger 5, where it transfers part of the heat of the binary mixture and enters the receiving tank 6 and then through the solenoid valve 11 to the storage tank 8. During rain, the amount of water coming from the roof exceeds the amount of water supplied on the roof, which causes the filling of the storage tank 8 to the upper level, the automatic control of the electromagnetic valve 11 closes it, the water rises to the level of the partition 9, overflows and through the overflow pipe 10 is removed outside Turning off the pump 15, and through the nozzle 13 of the thermotransformer 7, a liquid binary mixture is supplied to the water-water heat exchanger 5, the binary mixture at the bottom of the thermotransformer 7 has a temperature lower than the ambient temperature, since the heat exchanger 12 takes part of the heat of the binary mixture, and heated water through the pipe 14 is directed to the consumer. The binary mixture supplied under pressure of the pump 15 to the water-water heat exchanger 5 is heated with water heated to ambient temperature, which is 10-15 ° C higher than the temperature of the incoming binary mixture, the refrigerant partially evaporates, removes heat from the heating water and the mixture of water and vapors under the pressure of the pump 15, the refrigerant flows further through the nozzle 14 into the thermotransformer 7, the nozzle 14 has a hole along its entire length and is immersed in the binary mixture, the refrigerant vapors are actively mixed and absorbed by water, and heat is generated (reaction isothermal) and the binary mixture is heated to a temperature of 50-90 ° C, heats the water in the heat exchanger 12 to the required temperature, the heated water from the heat exchanger 12 is sent to the consumer, the binary mixture in the thermotransformer 7, is cooled, is lowered down and fed through the pipe 13 to the pump 15 heat exchanger 5. The cycle repeats.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- cheaper water heating production due to the use of high ambient temperature in the spring-summer period;

- simplification of the design;

- improvement of the ecological environment.
