Canadian building heating technology - a more economical alternative to water and electric methods. It is based on the circulation of warm air in a closed conduit system, promoting uniform heat distribution throughout the building volume. Among the positive aspects of the techniques may be called the integration with the ventilation system, the addition in the form of filter elements, air conditioners and humidifiers.
In most cases, the method is used in the buildings of frame construction, which are widespread in Canada, because of what and the technology got its name. Due to insufficient wall thickness, compared to brick construction, the frame is not so good at trapping heat, produced by batteries, while air heating creates an optimum microclimate home with minimal financial expenditure.
design principles
Air efficient heating House on the Canadian methodology should ideally be formed on the building design stage to all pipelines were harmoniously entered in architecture. First, a draft is determined by what kind of cross-sectional area should have a tubing. Exceeding the optimum value will lead to unnecessary financial cost, insufficient cross section - in a low efficiency.
Of course, the master will be able to build the system in existing buildings, but in such a situation, the challenge is to make pipe unnoticeable, engineering design of the pipeline is not too well advanced and corresponds to a classic interiors.
A set of equipment
The following devices are required for correct operation:
- air heater running on gas.
- The heat exchange circuit in which the flowing air reaches a predetermined temperature, separated from combustion products.
- Pipes for supplying heated air into the room. About the types of tubes used should later tell apart.
- Air vents placed on the ceiling, walls and floor. With their help, the heated air is supplied to rooms. Movable shutters on the grids allow to adjust the power of the thermal air flow to achieve the necessary climate conditions.
- Fan, provides system efficiency, which guarantees a constant flow of air into the circuit.
- Mechanical cleaning of filters, air conditioners, humidifiers, i.e. mechanisms and consumable items that contribute to improve air quality, variation in the settings providing environmental parameters.
- Electronic sensors automatically maintain the basic operating parameters, prevent dangerous accidents.
varieties of pipes
several types of pipes used in the formation of the system:
- Rectangular profile is considered to be the most common, perfectly compatible with suspended ceilings.
- The cheapest round tubes are considered. They are very easy to mix, there is no need to use special hardware. Unfortunately, the working area of such a profile 12 percent lower than that of the square tube section of a similar live.
- It is also used and flexible pipes, which are based on synthetic material. They are divided into non-insulated and insulated, enclosed in a special frozen foam, reducing the dependence of the internal environment from the external environment.
working principle
The action of the whole circuit is based on the fact that the fan is exposed to cold outside air to the generator, where the its heating, cleansing, moisturizing and sending to the pipe to further evenly distribute over the entire volume home. As we know from school physics course, natural convection involves the rise of warm air upward, and therefore the feed lattice is better positioned closer to the floor.
If say, a fuel is preferable for the generator, the best option - gas. This embodiment is economical, requires the almost total absence of combustion products, is safe.
Optional equipment
Adjustable ventilation allows you to determine exactly how much of the cold air will come from the street to warm up in the system. Some options include work extremely closed cycle, ie the inflow of fresh outside air is completely absent, but a more preferred embodiment, when such a function supported.
No harm will be also the presence of the thermostat, adjustable manually and automatically. Automatic equipment allows the formation of the whole climate programs, varying temperatures, depending on the time of year, time of day.
Finally, the experts also strongly recommended to install the moisture sensor. To achieve the desired level varies the ratio between the outdoors and the room air.
Advantages and disadvantages
Positive features of the Canadian method is as follows:
- System efficiency is often up to 90 percent, which is almost one-third higher than that of water analog. This is due to the low energy consumption.
- Economic benefits. Heating circuit does not involve the installation of expensive pipes, radiators from specialized alloys.
- Saving room interior. Ducts are under suspended ceilings, can be placed inside the walls, so imperceptible.
- The combined operation with ventilation, humidification, cleaning, air conditioning.
- The minimum level of inertia, after 10 minutes of operation, the desired temperature is reached.
- Automatic control, no accidents.
- The absence of water which may freeze when an extraordinary situation (failure of the heat source, the deliberate disconnection of the heat generator, the heat generator volatile unintentional disconnection and the like)
- The lack of antifreeze, which must be replaced periodically. In fact, many manufacturers do not give guarantees on the boiler if the system is filled something other than water.
- It becomes accessible air recuperation system (waste heat to preheat the fresh air). system efficiency increases.
- Installation of the system is simple, there is no need for costly plumbing services, as air mikroutechki virtually no effect on the system.
If we talk about the shortcomings, that their number is minimal. In case of wrong calculation, for example, the system works with some noise. Another minus - poor location gratings sometimes leads to the rise of the dust from the floor, which makes most engaged wet cleaning. The third drawback - a man comfortable with air heating from 18 degrees Celsius when water or furnace heating from 16 degrees Centigrade (due to radiation). The fourth negative - the designer needs. Fifth minus - an open question: "How to rinse the pipes if they accumulated dust?". Sixth negative - if the pipelines are under the ceiling, it is necessary to lay the project stage higher ceiling heights, for the diameter of the pipeline.
Thus, in many situations it is a way to heat the building is preferred. The main thing - to entrust the settlement of accounts professionals to during the operation did not have any problems.
