The inventive system is an Autonomous power and heat supply of residential and industrial premises operates as follows.

Power SUPPLY SYSTEM

The main source of electricity for the operation of a heating system, hot and cold water supply, and power household appliances is wind installation 1. Uninterrupted power supply is ensured through the use of the battery 2. Control power supply system is an automatic control system 9 through the sensor controller 29 for monitoring the condition of the batteries 2 and regulation of the electricity system. In the case of discharge of the rechargeable battery 2 controller 29 provides the power supply for charging the battery 2. In case of lack of power generated (for example, at low wind) controller 29 provides the flow in the network of consumers of missing energy from the battery is nuclear biological chemical (NBC battery 2 through the inverter 6, converts a DC voltage of the battery 2 in a variable.

HEATING SYSTEM

The main source of heat is a device for converting solar energy into thermal energy 3. Coolant, for example, the coolant heated in the solar collectors 10 transfers heat through the heat exchanger 11 to the coolant in the heat accumulator 4. Circulation in the kennel installation for the conversion of solar energy into thermal energy 3 carries out the pump 21. Depending on the sensors 24 outdoor air temperature sensor 28, the temperature of the coolant in the heat accumulator 4 the following modes: a) t° sensor 24>t° sensor 28: pump 21 is continuously on and the coolant is continuously circulated along the contour; b) t° sensor 24≤t° sensor 28: pump 21 is turned off, the system goes into standby mode. When the temperature in the solar collector 10 values t° sensor 28+Δ°included With the pump 21; t° sensor 21>90°and t° sensor 28>100°With: a three-way valve 33 switches the solar collector 10 to the heat exchanger 12 and includes pumps 21, 23, which provides the excess heat in the ground. The circulation of coolant between the heat accumulator 4 and the radiators shall pump 22. As heating devices use what is the system “warm floor”, superior to traditional heat “heat sinks”. Additional sources of thermal energy when the wind turbine 1 is the heat pump 5, carrying out, if necessary, heating of the coolant supplied to the network of consumers of thermal energy.

In the warm time of day (day) or year (summer) is the accumulation of heat in the heat accumulator 4, wherein the heating devices are disabled: the valve 31 is open and the valve 32 is closed. If the temperature in the heat accumulator 4 below 60° (in the absence of the sun or at night), turn the pump 22 to circulate the coolant of the heat accumulator 4 through heat exchanger 20, which is embedded in the capacitor 18 of the heat pump 5 to heat.

In the cold season (winter) is the return of the accumulated heat in the network of consumers. Heating appliances included, for which the valve 31 is closed and valve 32 is opened. The operation of the heating system controls automatic control system 9. The circulation of coolant between the heat accumulator 4 and the radiators shall pump 22. The temperature at the inlet of the heating devices is determined depending on the outdoor temperature and monitored by the temperature sensor 25. Adjustment and support is of the required temperature provides PCs controlled three-way valve 30 by adding coolant from the back of the collector to the input of the system. When operating the heat pump 5, the outlet temperature of the heat exchanger 20 is increased. Compensation of the temperature increment is managed by the automatic control valve 30, increasing the share of “reverse” cold coolant inlet of the heat exchanger 20, and hot from the heat accumulator 4 is decreasing, and, in certain conditions, can stop fully. It allows you conserve thermal energy battery 4

HOT WATER supply SYSTEM

The hot water system provides heat pump 5. When the temperature in the hot water tank is below a certain value that is recorded by the sensor 26, enables the heat pump 5 and the pump 23 of the circulation fluid in the circuit formed by the collector heat of the Earth 8, placed in the ground, and the heat exchanger 13, where the dissipation of heat generated by the evaporator 15 and passed through the condenser 17 water in the tank 19. The day when turning on the heat pump 5 heat source becomes a solar collector 10, which significantly increases the efficiency of the process of preparing hot water. The three-way valve 33 switches the solar collector to the heat exchanger 12, a built-in heat exchanger 13, where after filling his coolant transfers heat to the evaporator 15, and the pump 23 is not included.

Complement is determined as being the source of heat in the production of hot water is the heat exchanger wastewater 7. Before discharge into the sewage system, wastewater flows into the heat exchanger 7, where the dissipation of heat generated by the evaporator 16 of the heat pump 5 and return it through the condenser 17 in the hot water tank 19. Heat recycling wastewater allows up to 80% to reduce the cost of hot water.

The CONTROL SYSTEM power SUPPLY

Control power supply system is fully automated. Automatic control system 9 operates on the basis of a computer with appropriate software. Input system signals from sensors 24-29. The received information is processed and determined by the behavior of all system elements. Then the output of the ACS produces signals for the switch 36, the control of the main devices of your system. The ACS power is supplied from a separate battery (not shown).

SUBSTANCE: invention can be used for converting energy of air flows into electric energy. Proposed method includes passing of first on-coming air flow between two conversing and diverging aerodynamic surfaces in direction of flow to form zone of reduced pressure and transmitting of second air flow along pipeline from surrounding space into zone of reduced pressure. Converter is installed on way of second air flow. Space is made in zone of reduced pressure in, at least, one of aerodynamic surfaces to provide swirling of second air flow by wall of said space. Swirling of second air flow is formed tangentially in direction of passing of first on-coming air flow. Device contains two plates. Pipeline is designed to transmit second air flow. One end of pipeline is made open and it is connected with surrounding space, and other end is connected to outer surface of one of plates. Converter is installed in pipeline. AT least one of plates is provided with space to swirl second air flow. Space communicates with pipeline. Space is made orthogonally relative to direction of first on-coming air flow tangentially in direction of first on-coming air flow.

EFFECT: improved efficiency of energy conversion.
