Electricity has become such an integral part of life in the house that sometimes they begin to notice its need only when a malfunction occurs. Often this makes us helpless, because without it it is impossible to do even the most basic things. To prevent such situations, create additional power sources. Often in their role are current generators that provide electrical energy to the house. They can operate on diesel, gasoline and gas fuels.
A gas generator is an electric energy device that operates on gas and serves for the main or emergency electrical supply of homes, enterprises and summer cottages. The principle of operation of such an aggregate is to transform the energy of gas combustion into mechanical energy, and its energy into electrical energy.
It is recommended to choose a gas generator for a home with auto start. This option will be the best. What is its structure, principle of operation and features, we learn from the article.
Gas generator for home with auto start
Gas units have advantages over other types of devices. For gasoline work, it’s only enough for a few hours, a “trouble” in winter can happen with a diesel engine if summer diesel fuel is refueled. But gas can be enough even for four years of operation, and when connected to the trunk line, the need for refueling will disappear completely.
Ensuring autorun is a difficult engineering task. It’s still not enough to buy a gas generator for a home with a Honda auto start or any other specific model of this manufacturer. The operating conditions, as well as the features of the operation and installation of additional equipment, must be taken into account.
Device
Modern generators can supply electrical energy for lighting devices, equipment, and heating boilers. Moreover, additional stabilizers for them will not be required. They are connected directly from the home network. A gas generator for a home with auto start can have different power: from two to three hundred kilowatts. Three to five kilowatts is enough for everyday life, in large cottages - ten to fifteen. Advanced models can adjust the voltage automatically. They have a protective system against overloads and monitoring devices.
The household gas generator for a home with auto start is equipped with an internal combustion engine, which operates on liquefied gas or fuel from the main pipeline. Motors can be two-stroke or four-stroke. The pressure in the line is the same as in a regular home network. Connection is carried out using a gearbox and a stopcock. Units are characterized by economical consumption and relatively low noise level.
Operating principle
The simplest gas generator consists of a compressor, a turbine and a combustion chamber. Gas here is a working fluid. Air enters the compressor where pressure rises. Then it goes to the combustion chamber, where it ignites.
Combustion is carried out at constant pressure, and the combustion chamber serves only to raise the temperature. At high rates, gas will flow into the turbine, where the blades rotate due to energy. Approximately sixty percent of the electrical energy is used to move the compressor, and the rest goes to turn on the device.
Installation and Connection
The device is installed in rooms with good sound insulation. It is also necessary to provide good ventilation in order to vent exhaust fumes. Stable ventilation will be forced electric system. Its launch should be included automatically together with the gas generator. However, natural ventilation should also be provided. The exhaust pipe is connected tightly to the gas outlet, which is released into the street.
The temperature must be above the zero mark so that the oil in the engine does not freeze and it is easier to start. The size of the room should be more than fifteen cubic meters. It should be above ground level and easily accessible.
You also need to control the pressure, which should be from two to six kPa. This task is carried out using a manometer. It is not necessary to connect a gas generator for a home with auto start to the main pipeline. Feedback from many users suggests that for such capacities, a cylinder that is connected via a gearbox is sufficient.
General recommendations
So, when connecting a gas generator, it is necessary to take into account all the above points, as well as ensure environmental safety and noiselessness.
To summarize a few points.
- Forced heat removal from the unit is necessary so that the engine does not jam from overheating. At the same time, when installing an electric fan, it should be borne in mind that it will consume part of the electric power from the generator.
- In a room with a generator, air exchange must be provided, for example, using automated electric blinds. Then there will be enough fresh air to operate and cool the generator.
- To suppress noise, additionally install soundproof covers, automatic fire extinguishing, lighting systems and provide thermal stabilization.
Manufacturers and their generators
For all systems to function normally, the power in the gas generator for a home with auto start, 5 kW is considered quite enough. Such devices are typically single phase. But sometimes they acquire more powerful units. As an example, you can take any gas generator for a home with auto start. The three-phase apparatus from Green Power is widespread and is trusted by Russian consumers.
Well-established products are companies REG, Russian Engineering Group, as well as GAZLUX. The joint developments of the Russian manufacturer Gaslux and the Chinese company Shangai Chenchang Power Technology (the leader among manufacturers of low-power generator) deserve positive feedback. An excellent gas generator for a home with a 10 kW auto start is offered by Generac. Its distinctive characteristic is the presence of noise-protective covers. Such devices are able to work directly on the street.
Advantages and disadvantages
The gas generator has the following advantages over other models:
- lack of need for refueling;
- clean burning;
- low fluid consumption;
- access during failures in electric energy;
- no need to purchase an additional tank;
- the ability to connect a switch and a control meter.
But also he is not without some drawbacks, among which:
- there is no opportunity to work in natural disasters;
- low power;
- large volume;
- the complexity of the design, because of which the repair will cost a lot;
- high cost of connection.
Thus, the installation, despite the presence of certain shortcomings, is an excellent option for a private house or cottage, distinguishing itself from other types of generators.
