INVENTION
Patent of the Russian Federation RU2084768
METHOD OF HEAT SUPPLY
The name of the inventor: Vasily Ivanovich Maziev
The name of the patent holder: Vasilii Maziy
Address for correspondence:
The effective date of the patent: 1993.06.09
Use: to hydropower, in particular to the method of heat supply. SUMMARY OF THE INVENTION: With the help of a heat pump compressor, the heating of the water of the heat supply system is carried out in the heat exchanger, while a jet hydraulic turbine is used as the drive of the heat pump compressor with outlet nozzles made along arcs of a circle and attached to the diffuser body of the turbine tangentially; the turbine shaft is connected by a conical And planetary gearboxes with the heat pump shaft, and the latter installs the water pump of the heat supply system, while ensuring the compression ratio of the air in the compressor is 3.25-3.35, and the cold received in the heat pump is supplied to the consumer for domestic needs.
DESCRIPTION OF THE INVENTION
The invention relates to the field of energy and can be used for heat supply.
Electric water heaters with thermodynamic elements are known (see Figure 94, page 149 of the book "Fundamentals of Thermodynamics and Heat Engineering" by VG Erokhin, MG Makhanka and PI Samoylenko, M. Mashinostroenie, 1980). An important advantage Electric water heaters is the absence of smoke, dirt and soot, the lack of electric water heaters is that they consume expensive, scarce electricity. The essence of the proposed invention is that, for the purposes of heat supply, a cheap water head is used, without taking into account the losses, the water pressure efficiency is doubled. Those. There is a utilization of solar heat scattered in the earth's atmosphere.

FIG. 1 shows a kinematic diagram of a heat supply method, where 1 is a dam; 2 reactive hydraulic turbine; 3 conical and planetary reduction gear; 4 heat pump shaft; 5 heat exchanger; 6 water pump; 7 - consumers of heat and cold.
In Fig. 2 shows a diagram of a reactive hydraulic turbine, where 
- angular velocity of the turbine wheel; R is the radius of the turbine wheel; U rate of water outflow at the outlet of the hydraulic jet turbine outlet; H water head, m, 
The essence of the invention is expressed in the combination of the following features: in use for the drive of a conical and planetary reducer of a reactive hydraulic turbine with outlet nozzles made along arcs of a circle and attached to the diffuser body of the turbine along the tangent, in this case the efficiency of the turbine is calculated by the formula: 
In the use of a heat pump whose shaft is connected to the sun gear of a planetary gearbox.
The heat pump compressor operates with parameters that ensure the maximum efficiency of the heat pump 
Where 
Optimum parameters of the heat pump, 
C Efficiency of air compression 0.85, P Efficiency of expansion of air 0,95, T 3 320 K,
Compression ratio 
L = 1.4 1.43;
Q heat energy equivalent to the energy of the heat pump drive; 
Cp (T n- T h ) is the heat squeezed out by the heat pump from the solar heat scattered in the earth's atmosphere.
Taking into account the losses of the hydraulic turbine to friction H = 0.95, H Hydraulic turbine efficiency, the invention provides a technical result in the heat supply mode T = 0.95 · 2.44 = 2.08 g
CLAIM
The method of heat supply comprising the steps of: using a heat pump compressor, the heating of the water of the heat supply system is carried out in the heat exchanger, characterized in that a hydraulic turbine is used as the drive of the heat pump compressor with outlet nozzles made along arcs of a circle and attached to the diffuser housing of the turbine Tangential, the shaft of the turbine is connected by means of a conical and planetary gearboxes to the heat pump shaft, and the latter is fitted with a water pump of the heat supply system, while ensuring the compression ratio of the air in the compressor is 3.25 3.35, and the cold received in the heat pump is supplied to the consumer for domestic needs .
