The invention is intended for individual buildings of type cottage, but can be used for heating of private apartment buildings in areas where no Central heating.

It is known device is a heat pump used for heating of individual buildings containing the compressor, evaporator, condenser and choke [1, 2]. As the heat is often used freon. In this device, the compressor, evaporator creates a reduced pressure, so that the freon quickly evaporates and absorbs heat from the water environment with a temperature of 5-10°With: sea, lakes, rivers. Evaporated refrigerant at high pressure created by the compressor is condensed and heat due to the condensation heat can be used for water heating water heating to a temperature of 40-50°C. through the reactor liquid refrigerant returns to the evaporator, completing the operating cycle.

The main drawback of the heat pump is that it is more difficult to use in severe cold, typical for Russia, and because they are primarily used in the southern regions for heating facilities in the coastal cities of the Crimea and the Caucasus.

An additional disadvantage of the heat pumps is their structural complexity in a real application.

A known system of water heating is of [3], containing heated gas or fuel oil, or electricity to the boiler, from which pump hot water by pipeline to the radiators heated space and leaving them for re-heating, is returned to the boiler, thus completing the operating cycle.

The main disadvantage of this device is quite complex and time - efficient water boiler [3].

The closest in technical essence and the achieved technical result is a device for heating of individual buildings, containing a compressor for compressing coolant, which is driven by the engine, heaters, installed in heated spaces, and piping coolant with taps to adjust [4].

The aim of the present invention is to provide a simple device for heating buildings, in which there is no boiler, and which can be used in any climatic conditions.

This is due to the fact that the device for heating of individual buildings, containing a compressor for compressing coolant, which is driven by the engine, heaters, installed in heated premises, pipelines coolant valves to adjust, characterized in that it is made with a closed circulation of coolant, the coolant I had is compressed air, o adiabatically heated in the compressor, and the device further comprises a balloon with air at a pressure of 10-150 at to fill their devices and control the pressure therein, insulated drive hot air installed between the compressor and the coils connected to the heat exchanger for heating water used for domestic purposes, and as the engine uses an internal combustion engine on natural gas or liquid fuel or electric motor, is connected to the mains and pipelines are made insulated.

A device with an open circulation differs in that after the heat exchanger is made faucet to release exhaust air into the environment, and the valve opening access of air from the environment into the compressor.

The method of operation of the device when closed, the brine is characterized by the fact that the air at an initial pressure of 1-3 at temperature 25-30°and o adiabatically compressed by pressure increase in 1,5-3 times and heated at 35-110°With up to a temperature of 60-140° [5, 6], and enters the radiators for heating buildings, the comfort of which he forwarded to the heat exchanger, cooled by flowing water, where water is heated and used for domestic purposes, and cooled to the initial temperature of the air enters the compressor, completing the operating cycle.

The method of operation of the device when open the brine is characterized by the fact that the air-coolant through a special valve is continuously sucked from the environment, and after exiting the heat exchanger through a special valve is released into the environment.

The second method is less preferred, because in the winter to heat the cold air will need more energy, resulting in greater degree of adiabatic compression in the compressor.

The essence of the invention is that the compressor adiabatic relatively little air is compressed, 1.5-3 times, allows you to simply heat the air to temperatures used in devices for heating buildings. Boiler for heating fluid becomes excessive, and the energy consumption for heating is the same or less because there are no heat losses with flue gases.

The drawing shows a diagram of the device.

The device consists of a compressor 1, a heat-insulated pipeline 2, the drive hot air 3, the heat-insulated pipe 4, valve 5, regulating the total flow of hot air, valves 6, which regulates the flow of hot air in each air heater 7, insulated pipes 8, 9 and 10, providing a reverse flow of hot exhaust is otdyha in the compressor 1, heat exchanger 11 for cooling the exhaust air and hot water for household needs, the pressure sensors 12 and temperature 13 (thermocouple), leaving the compressor and entering the compressor 14 and 15. To control the temperature of the water heated in the heat exchanger 11, a sensor 16. For intake of outside air to a certain pressure made pipe with a valve 17. To transfer the device from the closed circulation of the coolant in the open made the valve 18, which opens the exit of exhaust air into the environment and the closing of its access to the compressor 1 from the environment through the pipeline 10.

The compressor operates with an internal combustion engine running on natural gas or liquid fuel, or the motor is plugged in. If necessary, the internal combustion engine can be attached to the generator. In this case, the proposed device provides not only the heating of the building, but can also Autonomous to supply the building with electricity.

The operation of the device when closed, the circulation of the coolant occurs in the following way. Initially the air tank with a large (10-150 at) pressure through the reduction gear and the valve 17 is attached to the device and fill it with air to a pressure of 1-2 at. Further, the valve 17 is closed and the compressor 1. To mpressor sucks the air from the pipeline 10, o adiabatically compresses it, increasing the pressure in 1,5-3 times, i.e. up to 2.2-6 antibody, depending on the set temperature of the air used for heating. Due to the adiabatic compression of the air temperature in the compressor is increased from the initial 25-30°60-140°and the air pipe 2 is directed to the insulated drive 3, which softens the pressure changes when changing operating modes of the device.

Next, the hot air through the pipeline 4 through the valve 5 and cranes heaters 6 is supplied to the heaters 7, warming the room. Exhaust hot air through the pipes 8 and 9 is fed into the heat exchanger 11, where the hot air is cooled to a temperature of 25-30°heating this water to be used wholly or partly for domestic purposes, and then re-enters the compressor 1, thus completing the operating cycle.

Adjusting operation of the device after activation of the compressor by varying the power of the overall air flow through valve 5 and the valves 6 individual coils 7. Control over the pressure and temperature of the air leaving the compressor is performed by the respective sensors 12 and 13, and for the same parameters of the air entering the compressor, the pressure sensor 14 and temperature 15. The temperature of the hot water produced in the heat exchanger 11, measures the temperature sensor 16. Regulirovat is that temperature can be a temperature, coming into the heat exchanger, and the flow rate of water flowing through the heat exchanger 11. To change the working pressure when the device and thereby to adjust its work with crane 17, gently letting out of the Ballon additional portion of air or releasing part through the valve 17.

Using temperature sensors and pressure can be arranged to automatically maintain the desired operating modes of the device.

In the open mode air circulation in General, the operation of the device occurs, as with a closed circulation, the valve 17 is opened, and air is continuously sucked from the environment, and the valve 18 is turned to a position where the exhaust air from the heat exchanger 11 is released into the environment and closes his access to the compressor 1 via line 10. As sucked in from the ambient air during the heating season has a low temperature, to obtain air temperature necessary for heating, the degree of adiabatic compression should be more and can be adjusted automatically depending on the temperature of the ambient air.

The design of the proposed device is very simple, and its creation does not require a large investment. It will provide warmth and additionally electricity in buildings in which Yonah, where missing or collapsed extensive heating and electricity, but there are oil and gas fields, i.e. this device is very useful for areas of Siberia and the Far East. This device is very useful for the European part of Russia, because in these places there are extensive gas transportation network, and it is also possible to purchase cylinders with origianal gas, which is cheaper than other liquid fuels.

A very important advantage of the proposed device is the provision of heat and electricity, regardless of the existing energy companies, which have an approximate payers winter off the heat and power supply only, because the area in the middle has a significant amount of one company.

The economic effect of the proposed device is very large, but quantitatively it is currently difficult to estimate.
