Gas automation aogv 23. Heating systems for country and country houses. Boilers, geysers, water heaters - Repair, service, operation. Recommendations for assembly and installation. Safety Requirements


The most affordable energy resource with a minimum level of harmful emissions in the modern world is gas. The use of AGV for space heating is the most effective option in terms of efficiency and safety. Independence from power supply and low cost maintenance allow water heaters to take their rightful place among similar devices.

Water-heating boilers AGV, using gas as an energy carrier, began to be produced by ZhMZ (Zhukovsky Machine-Building Plant) since 1967. The new generation of gas heaters is capable of heating homes up to 140–200 m², and the equipment can also be used to provide hot water. TO The catches are equipped with a reliable automatic gas supply control system.

ZhMZ products are now represented by about 30 types of boilers. Among them are modifications with power from 11 kW to 68 kW - AOGV, KOV, AKGV. Certified devices that have permission to manufacture and use are capable of heating up to 610 m² of area.

The principle of operation of the AGV

The basis of the design of AGV devices is a cylindrical tank connected by a pipeline system to the entire heating network of the house. Inside the cylinder there is a heat exchanger - a flame tube heated during gas combustion. In the AGV-80 and AGV-120 devices, a turbulator was placed inside, which slightly increased the efficiency of the installation.

The heating system is a network of ascending pipeline, radiators, expansion tank and return pipeline.

This system provides full cycle of the device which includes:

  • heating of the coolant - water;
  • the rise of the heated coolant through the ascending pipeline to the heating devices - radiators;
  • heat transfer;
  • return of water to the device for subsequent heating.

The thermosiphon heating system (or natural circulation system) does not require additional installation of pumps, and compensation for water losses occurs from the expansion tank. Waste products of gas combustion enter the chimney and are removed into the atmosphere.

IMPORTANT! The AGV system allows you to install a pump to ensure forced circulation of water. Such a boiler will no longer be considered non-volatile, since electricity is required for the operation of the pump.

The AGV-80 and AGV-120 devices were equipped with an automatic device that prevented the supply of energy carrier when a certain temperature was reached, when the burner wick spontaneously went out, the draft in the chimney decreased, or when the gas pressure in the main was reduced.

When the coolant temperature drops, the automatic sensor is triggered, including the gas supply to the burner.

New generation AGV devices are distinguished by a more efficient design, but all heat and water heating systems operate in the mode of a conventional gas boiler. Structural differences are in the division of the flame tube into separate sections. A coil for hot water preparation is also mounted in the water jacket.

The technical parameters of the first and one of the latest modifications of AGV boilers are presented below:

Thermal power Heated area tank capacity efficiency Maximum water heating temperature
AGV-80 7 kW up to 60 m² 80 l 75% 90˚ 85 kg
AOGV-23.2 23.2 kW up to 200 m² 35 l 89% 95˚ 55 kg

Advantages and disadvantages

A major significant advantage, which distinguishes AGV gas boilers from similar equipment, is their independence from the supply of electricity, in other words, there is no need for. Others "pros" the use of devices are recognized:

  • affordable price;
  • high efficiency indicators: the effect obtained from the use significantly exceeds the costs of ensuring the operation of the boiler;
  • reliability and safety of boiler operation;
  • ease of maintenance.

Available Benefits cannot smooth out the characteristic "Cons" that negatively affect the characteristics of the equipment:

  1. This is a low efficiency;
  2. Equipped with unreliable automation;
  3. Significant dimensions of the devices themselves and large diameter pipes;
  4. The need for strict observance of pipe slopes during their installation.

Knowing the strengths and weaknesses of the equipment, you can reasonably approach the choice.

We choose AGV (gas boiler) for a private house

Features of the house (area, building materials used) and the climatic characteristics of the area - one of the main criteria for a successful choice heating and hot water equipment. The second important feature is the power of the boiler.

Important! Multiplying the power value by 10 m² of area will tell you how much area the boiler can heat. For regions with a harsh climate, it is necessary to provide a power reserve of 25%.

The criterion determining the choice is the price of the equipment, as well as the cost of the materials necessary for operation. Compared to imported analogues, domestic devices are cheaper by ≈ 35%, the cost of maintenance is also three times lower.

Gas boiler AOGV-11.6 and AOGV - 23

The AOGV-11.6 apparatus is a floor modification of equipment from the range of single-circuit boilers of the Zhukovsky Machine Plant (ZHMZ). Designed exclusively for heating needs. Its marking stands for "gas water heating apparatus". The next figure in the brand designation indicates its power - 11.6 kW.

Models AOGV-11.6-3 ("Economy" and "Universal") are double-circuit boilers and can provide the consumer, in addition to heating, also with hot water. With single-circuit devices, these boilers differ in the presence of a steel coil in the design.


They differ from each other in the features of automatic systems (the first of these is equipped with domestic automation, "Universal" works with the Italian system).

Modern gas boiler AOGV - 23 is distinguished not only by an improved appearance, but also by the modernization of some structural elements:

  • durable Italian thermometers were installed instead of unreliable domestic-made glassware;
  • automation system of the American company Honeywell allows you to control the smoke exhaust system, maintain heating, turn off the gas in case of breakdowns in the system, in the absence of a burner flame, it blocks the operation of water-heating equipment;
  • complete set with an injection burner allows for the most complete combustion of gas without residue.

The use of a new coating technology on the metal surface of the boiler body provided an attractive appearance of the equipment. This makes AGV (gas boilers) a good choice for a private house or summer cottage.

Important! The boiler room can be located anywhere, but not in a residential area. It is imperative to provide for the possibility of air inflow and exhaust in the furnace.

Installation of equipment in accordance with certain technical standards and safety requirements can be carried out by a specialized organization. The exact implementation of all rules, instructions and recommendations for installing the boiler is checked by a representative of the gas inspectorate.

Important! The inspector will give permission to connect the equipment to the main in case of full implementation of all the requirements of the project documentation, security.

    DEVICE AND PRINCIPLE OF WORK.

    The device consists of the following components and parts: a heat exchanger tank, a main burner, an ignition burner block with a thermocouple and an ignition electrode installed in it, a combined gas valve (multifunctional regulator), a draft stabilizer, lining parts.

    In the upper part of the tank - heat exchanger, a temperature controller sensor is installed, connected by a capillary tube to the thermostatic valve actuator ("bellows - thermoballoon" system), and a thermometer sensor

    The design feature of the 630 EUROSIT combined valve is the presence of a device for stabilizing the outlet gas pressure, as well as the combination of valve control in one handle with the designation of the positions by the corresponding symbols and numbers on its end face and the pointer on the valve cover. The dependence of the temperature of the heated water on the position of the control knob scale is shown below:

    The principle of operation of the temperature controller is based on the expansion of the liquid when heated. The working fluid, heated in the sensor (thermoballoon) from the water in the heat exchanger tank heated by the combustion of natural gas, expands and flows through the capillary tube into the bellows, which converts the volumetric expansion into a linear movement of the mechanism that drives the system of two valves (instantaneous and metering ). The design of the mechanism provides protection against thermal overload, which protects the "bellows - thermal bulb" system from damage and depressurization.

    1. When setting the desired water temperature in the apparatus with the control knob to increase, the instantaneous (click) valve first opens, then the dosing valve.
    2. When the water temperature in the device reaches the set value, the dosing valve is smoothly closed, switching the main burner to the "small gas" mode.
    3. When the temperature rises above the set value, an instantaneous (click) valve is activated, completely shutting off the gas to the main burner.
    4. In the absence of draft in the chimney, the exhaust gases from the furnace heat the draft sensor, the sensor is triggered by opening the normally closed contacts of the thermocouple circuit. The electromagnetic (inlet) valve closes and shuts off gas access to the main and pilot burners. The draft sensor is designed to operate during the absence of thrust for at least 10 seconds.
    5. When the gas supply from the network is interrupted, the pilot burner instantly goes out, the thermocouple cools down, the electromagnetic valve closes, blocking the gas access to the main and pilot burners. When the gas supply is resumed, the passage through the apparatus is completely blocked.
    6. When the gas pressure in the network drops below 0.65 kPa, the gas pressure on the pilot burner will also drop, the thermocouple EMF will drop to a value insufficient to hold the valve. The solenoid valve will close and cut off the gas supply to the burners.

    POSITIONING AND INSTALLATION

    Placement and installation of the apparatus, as well as gas supply to it, is carried out by a specialized construction and installation organization according to a project agreed with the operating enterprise (trust) of the gas facilities.
