The invention relates to an Autonomous life support systems (ALJ) of land, mostly Autonomous objects - residential buildings, industrial and public buildings, private Autonomous settlements, towns. The invention is intended to provide heat, hot water and electricity with stable frequency and voltage of the above objects. Used for rapid deployment of Autonomous residential complexes in all starting conditions in the absence of buildings, heat, fuel, communications, water. Can find applications for mobile systems in emergency situations and to organize a tent military bases and barracks in the field.

Life support systems in emergency situations in winter or cold climates organize by setting the campgrounds, or when the remaining buildings, but a broken heating systems carry out urgent repairs communications.

Repair damaged communications systems heating in winter is fraught with high costs for repairs, needs a large number of building materials and sophisticated machinery and long term repair.

For ALJ can be used known vortex power plant with the conversion of wind energy into elec the historical energy being accumulated in accumulators associated with the conversion of this energy into electricity with stable parameters, which then, of course, can be used for electricity and heat supply of buildings and other objects [1].

The disadvantage of such systems is the low energy power and complexity of the installation. The impossibility of working windmills in the absence of wind.

For adequate heat and stay settlements up to 300 person would need to install about 20 windmills. This is a very expensive, long and risky. To reduce the risk of lack of wind is necessary to install energy-intensive batteries, which further increases the cost of ALJ and makes it meaningless.

Also known Autonomous life-support system for Autonomous objects, for example ALJ space station "MIR", which contains solar panels and a device converting the received energy into electricity with parameters sufficient to charge the batteries provided in turn with the conversion of stored energy into electricity with the parameters necessary for operation of equipment of this Autonomous object and its heating and hot water supply [2].

The General disadvantages of the known solutions are her work on the scarlet number of people. For the sustenance of a large number of people it is not.

The prior art Autonomous life-support system (ALJ) [3] buildings and other objects that contain at least one source of free energy, the transducer of this energy into electrical energy provided from the energy accumulator, and devices convert battery power into heat and electrical energy supplied to the accepted objects, characterized in that the energy accumulator is made in the form of at least two heat accumulators: one low-temperature liquid, the second high-temperature solid-state, and the first battery is hydraulically communicated with the heating system and hot water supply of buildings, second - containing heater and refrigerator heat machine drive an electric generator provided at least with the power supply system of buildings.

The disadvantage of this ALJ is a need for a source of free energy, which in conditions of emergency or military field conditions, for example in the mountains, may not be.

In addition, mobility and operational efficiency of this system not to deploy.

Under any circumstances it is possible to quickly establish a known heating systems, which are based on electric boilers.

In the prior art Izv the local electric boilers [4, 5, 6, 7], which contains a water tank, inside of which is installed heating Elements.

The disadvantage of such boilers is a special requirement to the quality of the chemical composition of the water. Water containing lime, forms on the surface of the heating elements scale and leads them into disrepair.

Replacement of the heating Elements is expensive and technically difficult. Requires a full analysis of the tank. In emergency and field conditions is invalid.

The closest solution is induction boilers [8]. They are more reliable, have higher efficiency, close to 95-98%. The same solution [8] also patented utility model RF # 87856 and describes a device for induction heating of a liquid medium containing a cylindrical housing with a lid and a bottom, an inner ring mounted above the plate and having a through hole for the passage of the heated liquid medium, the coil, the inlet for the heated liquid medium and the outlet for the heated liquid medium, characterized in that it further comprises a Central inner cylindrical channel, mounted coaxially with the casing, the upper part of the Central internal cylindrical channel is connected to the cover and on its surface is a through hole for passage of the heated liquid medium, and the lower part is connected with the output Petruk the m for heated liquid medium, the inductor is made in the form of a cylindrical cavity, mounted between the housing and the Central internal cylindrical channel, with the formation of the annular channel for the passage of heated liquid medium, within the cylindrical cavity installed coil hermetically sealed dielectric binder material, the upper part is connected with the cover, and the bottom with the inner ring.

Induction electric boilers are designed for use in stand-alone heating systems, hot water in technological processes associated with intermediate heat carrier heating. The lack of direct heating in contrast to ten and gas heaters boilers allows to work much longer (over 30 years) without losing its technical parameters.

The disadvantage of such boilers is the use of a closed flow-through tank. As a result, the device cannot be adjusted by the power of heat. The boiler operates continuously, which does not allow to save energy. One boiler set on a certain area of the heated premises.

The device can not effectively work with organizations operating system backup heating or when the need to urgently increase the heating power with a significant lowering of temperature on the action.

The technical result is the possibility of mobile and rapid deployment of long term ALJ that does not require any initial conditions (buildings, communications, water, fuel, electricity), to regulate the heating power and not demanding to the choice of electrodes, which may be any steel pipes.

The way to rapid deployment of long-term Autonomous life support systems of many people in colder climates, characterized by the installation of heating systems, as the basis of which use high-voltage induction electric boiler, with a gasket from him pipeline connections to residential buildings or tent camp, characterized in that the power induction electric boilers use a diesel generator, the fuel which is delivered by tank, part of the produced electricity diesel generator divert communications on a residential building or a tent city, as the heat induction electric boilers use water, which is optionally delivered to the place of deployment of Autonomous systems the tank, and the induction electric boiler fulfill containing circulation pump, flow vertically mounted tanks, each of which isolated the van from another by means of feedthrough ceramic insulators, are you down voltage, and the inductor use electrodes made of stainless steel, which are mounted inside each flowing vertically installed tank with immersion into the tank at different depths.

In addition, the immersion of the electrodes at different depths provide by twisting or unscrewing from the body of the tank.

In addition, twisting or unscrewing from the body of the tank electrodes provide by means of the actuator with oil seals.

The inductor performed on the basis of the magnetic system and the primary winding consisting of coils, insulation class voltage. The coil is fixed to the frame using the adjusting elements, consisting of insulators (top and bottom of each coil) and the adjusting bolts.

On the outer surface of the inlet and outlet fittings sensors the temperature of the incoming and outgoing water, on the surface of the tubes of the heater - thermoswitches, and next to the input (bottom) flange - flow sensor.

The essence of the implementation of the heating system consists of the following. Electric boiler (see Figure 1) is an electric boiler indirect heating in which to get hot water is used, the heat released during the flow of induced electric current in the pipe wall (1) water heater, made the C corrosion-resistant austenitic steel, and inside the pipe passes the heated water. Through heated water, electric current does not pass, therefore the water requirements for specific electrical resistance is not produced.

For the water inlet and outlet are installed respectively input (2) output (3) flanges.

The inductor can be made on the basis of the magnetic system (4) and the primary winding consisting of coils (5)isolation voltage class. Coil fixed in the frame by using the adjusting elements, consisting of insulators (top and bottom of each coil) and the adjusting bolts. Pin the ends of the reels displayed on the insulators input unit (6). Input device made for cable connection. The magnetic circuit, the high voltage winding and the input device of the electric boilers are similar in design to the corresponding nodes of the dry transformer with air cooling. To intensify the cooling of the high-voltage winding in the lower part of the electric immersion heater installed centrifugal fans (7). Outside of the electric boiler is closed guard, preventing the active and current-carrying parts from the access to and ingress of foreign objects from the side and from above.

The water heater is connected to the grounded casing of electric boilers, plays the role of a secondary closed short-circuited winding of the transformer. From the supply network vodonagrevatel the eh separated by insulation voltage class. In any mode of operation, the voltage at the heater relative to the earth, and between the inlet and outlet flanges is equal to zero. In this regard, the electric boiler is allowed to be connected to the public electric network without isolation transformer and connect the pipelines of water supply to the electric boiler without insulating inserts.

To control thermal parameters on the outer surface of the inlet and outlet fittings installed temperature sensors (8) of the incoming and outgoing water. In addition, on the surface of the pipes of the water heater installed thermoswitches (9)intended for emergency shutdown of the electric immersion heater in case of overheating of the heater. Near the front (bottom) flange installed flow sensor (15)that is designed for emergency shutdown of electric boilers in case of violation of water circulation.

Lead wires from the cooling fans, and temperature sensors, flow and thermo switches connected to the terminals of the terminal block in the junction box connections (10)located on the side of the electric and closed panel protective cover.

To control the operation of electric boilers and protection from abnormal operating conditions in the kit with it comes the control Cabinet (SHU) with equipment control and protection. To SHU is connected to the wire connection, which should be under uedineny to the terminals of the box connection of electric boilers.

The operation of electric boilers is carried out automatically by the control equipment located in the control Cabinet. In emergency operation equipment protection disables the electric boiler.

Before enabling you to fill the hydraulic system, bleed the air from vozduhonosnykh devices in the system and on the electric. To release air from the heater electric immersion heater mounted faucet with drain tube (11), which should be open when filling and close after the appearance of the water in the tube. To turn on the circulation pump, to ensure the normal water circulation. Re-open vozduhonosnye device, ensuring no air in the system.

If necessary, emptying water heater electric boilers (for example, when the danger of frost), you must drain the water from the water system. For this purpose the lower ends of the manifolds may be provided by the stub (14), the opening of which will allow to drain excess water from the water heater.

Telesistema (see Figure 2), in which the electric boiler is a closed system with surge tank and a continuous forced circulation of coolant. Circulation can be provided by circulation pumps.

In addition to the heating produced by the electric heat can be used in order to find for heating water for household needs.

Electric boiler allows it to provide the feed control from an external water supply that maintains the required water volume in the system, by opening the valve to recharge and (when the pressure in the external water below the pressure in the system) the pump feed. From experience, in the absence of leaks in pipelines, the need to recharge the system occurs 2-3 times per month due to the evaporation of water from the expansion tank.

As the heat carrier in the heating system uses water from an external water supply, without additional processing (cleaning, addition of substances which improve the electrical conductivity etc). Thus, the properties of water when it is used in the system do not change and a constant periodic replacement (to avoid the devastating effects on pipelines and electric boilers) is not required.

Electric boiler (see Figure 2) operates on the principle of current flow through the coolant (water)having a specific resistance of the water column. United in the "star" of the electrodes (13) of the boiler complete the electrical circuit through the water, which thus is cooled, and the heating element. For the supply of electricity to the heat carrier are isolated from each other by means of feedthrough ceramic insulators (12) vertically mounted tanks (1), which summed voltage and, preferably, at least three electrodes (13) in each of the stainless steel, immersed in the coolant (water), inside tanks in the center and connected at the center point across the water in a "star".

The electrodes are held inside the tank by a support device (15)resting on the edge of the tank.

Heat output is thus dependent upon the depth of immersion of the electrodes (contact area supplies the power elements and the heat carrier and the distance from the terminals to the grounded structures (second pole)). Deeper immersion of the electrodes (13) tanks (16) causes an increase in current, and therefore power, the rise of the electrodes is reduced. Cold water from the bottom, the output of the hot - top. To provide the necessary electric power to the electrodes immersed into tanks to a predetermined depth. The lowering (raising) of the electrodes is made by twisting (unscrewing) of the boiler shell.

In order to provide power control of electric immersion heater without disconnecting it possible to update by installing the actuator with oil seals that will allow you to change the position of the electrodes even when the boiler.

Note that when using a boiler of similar design at a high voltage (10 kV) mo is no need to increase the diameter and height of the tanks to increase the distance of the breakdown and of the liquid column. Also when increasing the capacity of the boiler, will need to change the flow rate of the flowing fluid (to avoid overheating) by replacement of circulation pumps for units greater productivity and working pressure.

Overcurrent protection may be provided on the basis of the relay ET-521 powered by current transformers extreme phases across test blocks. When triggered, the relay will output protection relay, which is the closure of its contacts is samoderzhavie and supplies plus on the coil off, this triggered the alarm and opening the normally closed contact is removed operational current thermal protection.

Also provided by the disconnection of the electric immersion heater when the coolant specified maximum temperature and the subsequent automatic switching when the cooling fluid. It is implemented may be in contact thermometer TCH-160Cr-M1-UHL2, which allows you to change, if necessary, set the temperature, on / off, depending on outside temperature. Thus, the mode of operation of the boiler is intermittent (only the circulation pump). Due to thermal inertia of the fluid temperature inside the heated space remains constant, but there is saving power is the power, because the boiler does not operate continuously as in the case of the prototype.

For comparative characteristics of electric boilers for utility models with a capacity of 6 kV and industrially produced boilers 0,4 kV were performed control measurements of time and frequency of operation and the power consumption of these boilers.

Results

When normal, comfortable temperature (20-25C (SanPiN-96 "Hygienic requirements for microclimate in industrial premises and GOST 12.1.005-88 General sanitary-hygienic requirements to the air of the working area") in rooms heated by electric immersion heater 6 kW (total 10140 m3), electricity consumption per month was 63000 kW/hour. Specific energozatrat 1 m3- 6,21 kW/h per month.

When the electric 0,4 kV to ensure the same temperature in the premises of a heated building area of 728 m2(the volume of the heated space 1820 m3) electricity consumption per month was 12960 kW/hour. Specific energozatrat 1 m3- 7,12 kW/h per month.

Thus, this method of forming the ALJ on the basis of the high-voltage induction electric provides the ability to save power by adjusting the load.

Mobile deployment ALJ is provided (see figure 3) through installation the heating systems, as the basis of which use high-voltage induction electric boiler (17). From electric boilers (17) conduct pipeline communications (26) to residential buildings or tent camp (22). Preferably, communication is isolated so as not to lose heat.

For power induction electric immersion heater (17) use diesel generator (19), the fuel which is delivered by tank (24). Part of the produced electricity diesel generator (19) assign communications (21) on a residential building or tent camp (22).

As coolant induction electric boilers use water, which is optionally delivered to the place of deployment of Autonomous systems tank (25).

Induction electric boiler (17) perform containing circulating pump (18), running vertically mounted tanks, each of which is isolated from the other by means of feedthrough ceramic insulators, which sum up the tension.

Thus, all ALJ is deployed to the desired location through the use of multiple machines machinery (23), carrying equipment (high-voltage induction electric boiler (17), diesel generator (19), communication (21, 26), the pump (18), tents (22) if necessary, lamps lighting, etc. And, if necessary, due to multiple machines machinery (24, 25), carrying fuel and water.

Quickly ALJ can be removed and used in another place.
