🔧 Air heating private house: composition, advantages and disadvantages

It was warm and comfortable in every room, you should pay attention to the air heating private houses. Such systems have a number of advantages, advantageously excreting them among alternatives. Offer to deal with them and distinctive features of the device.

The structure and operation of the air heating system

The composition of air heating systems includes the following main elements:

• heater. Depending on the location of the private house and the availability of fuel selection can be made in favor of electric, solar, any type of heater, a gas boiler or other heater;
• heat exchangerProviding a direct heating of air;
• duct systemBy which provided the distribution of warm air masses throughout the home;
• control device. It adjusts the equipment operation for forming a suitable temperature.

The operating principle of air heating system is quite simple. Cold air passing through the heater, warms up to a predetermined temperature. Ducts allow its distribution in all rooms. After mixing of air masses inside the living rooms, comfort temperature is reached therein. In the process of heating equipment possible to avoid excessive pressure that can cause slamming doors or cause difficulties when windows are open.

Methods for air circulation

The movement of air over the elements air heating system may be implemented in various ways. Choosing a suitable option for a particular private home, meet with the distinctive characteristics of each. This will allow to make an informed decision.

natural

The basis of the natural circulation of air is necessary physical phenomenon in which hot air is always upward. As rise, it begins to displace cold layers, providing a gradual heating of the entire air space of the room. To ensure the operation of air heating system with natural circulation heater positioned in the lower part of a private home, usually in a basement. This allows to generate an adequate flow of warm air which will enter the space situated above, warming them to the optimum level. At the same time, the cold air will sink down to warm and rise up again.

The advantages of this process include the lack of multiple recirculation air, in which it is gradually saturated with carbon dioxide and dust.

compulsory

With forced circulation manages to provide a more accurate adjustment of the degree of heating of air mass flowing in each separate room. the fan is introduced to ensure the movement of air into the system. Thanks to his presence manages to stabilize the rate of coolant flow, to create constant pressure to stabilize the flow rate.

To ensure the efficiency of the additional equipment is introduced into the air heating system. The disadvantage of this method is attributed volatility. In the event of disruptions in the supply of electricity of a private house heating is stopped. Also heated difficulties may arise in case of failure of equipment. To avoid this, it is necessary to provide an alternative version of heating private houses, for example, water.

implementation of the heat exchange

The principle of operation of the heating system may be different. All depends on the heat exchange circuit. Each option has its own distinctive features. We offer to meet with the characteristics of each.

supply

In the system of forced-air heating is carried out in the following sequence:

• heat generated by heat source is supplied to the air heat exchanger;
• by a fan forced air inside private homes. After it enters the heat exchanger pre-filtering;
• distribution ducts provide hot air mass through the house;
• exhaust air hoods removed via the street.

The ratio of volume of air masses flowing into and output out, selected according to the required ventilation rate and squaring the room. To create a high-pressure air supply it to do more. Installation costs of such a system is relatively inexpensive. However, operating costs are obtained quite large.

recirculating

Such air heating private houses is carried out without the air vent on the street. The cooled air through air ducts to the heat exchanger and heated again. Are indoor air masses repeatedly pass through the heating system. For heating energy required minimum, which significantly reduces the cost of heating. Replenished only natural heat loss.

The disadvantage of such a system is closed. The air increases the concentration of dust and carbon dioxide. This option does not meet the requirements of hygiene.

Recirculating heat transfer happens with natural and forced ventilation system. In the first case, the hot air supply from the heat source is carried out through the ventilation channels. Then, as the cooling begins under the influence of gravity to descend. With minimal initial investment, easy installation and energy independence, the system allows you to maintain a comfortable microclimate. Indoors, there is considerable difference between the degree of warm air near the floor and the ceiling.

When selecting air handling system will be able to achieve maximum effect and to ensure full control of the climate in a private home. Air in the recirculation system misses passing the coarse and fine filters purification. Then, a certain amount is reset on the street, and in its place comes a fresh batch. This is followed by heating, and, if necessary, humidifying or dehumidifying.

Combined

Normally, when the heating device provides two different, unrelated circuit. However, in some cases, they do combined. They have as a heat source can be a diesel or electricity. The fan provides the injection of heated air. In private homes, such systems rarely mounted. Most often they are used for heating garages, workshops, industrial facilities.

Hardware requirements for air heating system

To-air heating has created a comfortable environment inside a private home, you should take a responsible approach to the choice of equipment.

Heat generators

When selecting the heat source selection can be made in favor of the air of a private house heating:

• electric heater;
• solid fuel boilers;
• gas equipment;
• devices running on liquid fuel (diesel).

When choosing a heat generators for air heating private houses should be aware that they must:

• switched on and off automatically;
• maintain air heating degree in the predetermined range.

Tip! If the choice is made in favor of the gas generator, it is worth considering some of the gas can run a particular device from the reduced or trunk.

Solid fuel boiler should allow to adjust the combustion rate.

ducts

Ducts provide a supply of heated air to the various rooms. Manufacturers offer products of different sizes. They can be square, rectangular, round. The choice is made taking into account the required capacity and the installation procedure. May be rigid or flexible.

Other elements

In addition to the heat source and the duct need additional equipment. Supply air fan should be to cope with the task. Together with the fan should buy a filter device, which can clear the air of fine dust and other impurities.

Air heating private house: advantages and disadvantages

Opting for air heating for private homes is due to its main advantages. To those should include:

The disadvantage is:

Engineering and design

Design of air heating systems of private houses should be given special attention. If there are errors, difficulties arise at the stage of installation and subsequent operation. Incorrect calculations can result in excess or insufficient power equipment, uneven warming of all or individual rooms, an abnormality in the air. To avoid these shortcomings in the work of the air vent of a private house, the following nuances should be considered when designing:

• heat loss is calculated for each flat separately. Their value affected by the number of windows, doors and a number of other parameters;
• heat loss by ventilation are determined by taking into account the number of people living in the house. This will determine how well the system can ensure the timely supply of sufficient fresh air volume;
• in the preparation of the basic elements of layout into account the location of other utilities, structural elements of the house and the interior;
• fuel type and capacity of the heat source are determined in advance. When calculating the power take into account not normalizable winter temperatures, a significant deviation from the established parameters in the event of abnormally cold winter;
• selection of optional equipment with the appropriate parameters.

Calculation of air heating for private homes in the following order:

• definition of heat premises;
• power selection heat source in view of the previously determined value;
• determining the volume of air that has come into the room;
• calculation of the duct;
• and determining the performance of the fan pressure.
