Weather in the house

Anna Bondarenko "are most important - the weather in the house" - sung in the famous song. Let's talk about the climate in a country house. And not in a figurative, but in fact that neither is a true sense of the word. Modern suburban houses are becoming increasingly tight: windows, quality doors, sealing interpanel joints - all this leads to the need for artificially creating the required indoor climate. This problem is not solved through open windows or switching on. Need installation of modern climate control systems. In its most general form can be divided into two large groups. The first - air conditioners (the so-called split systems) which are cooled, dried, heated and filtered air. The second component - the ventilation system to remove moist and polluted air from the room and serve in his stead filtered and heated outdoor air. Adjust the heat most common in country houses were split-system. This is a common name air conditioners, which consist of two separate blocks (split in translation from English - Separate). External unit (condensing unit) is located in front of the building. It can be wall, roof and balcony. Indoor unit (evaporator) is installed in the room itself. He maintains the desired temperature of air, distributes it around the room and runs almost noiselessly. Between the blocks are connected with electric wire and copper tubes in which circulates freon. Since the compressor is outside, in an external unit, the noise level in residential split-systems in the 8-12 times lower than that of air conditioners with combined condensing and evaporator units. Modern split-system can not only cool but also heat the air. They are equipped with remote control that lets you set the temperature in the room, set a timer to automatically turn on and off the air conditioner at a specified time, to regulate the air flow and more. Indoor units are fine filters and strainer to filter the air of dust, smoke, pollen, etc. The indoor unit split systems can be wall, floor, ceiling, columns and embedded in the ceiling (tape or channel). Variety of split systems indoor unit wall split systems installed anywhere in the wall. Power wall system is from 2 to 7 kW and allow to cool (warm) room from 15 to 70 m ?. Pluses wall types: reasonable price, take up little space, low noise, do not require a suspended ceiling, a large selection of options. Floor and Ceiling air conditioners are used where there is no possibility to use the system of the wall type and there is no ceiling. They are installed either at the bottom of the wall or ceiling. Air flow in the first case is directed upwards, in the second - along the ceiling. There are models of ceiling air conditioners, distributing the cooled air on four directions, and the power flow is regulated separately in each direction. The principle of air-conditioners of this type is the same as that of wall split-systems, only the floor-ceiling significantly greater breathability. They are more powerful, as calculated by one or more rooms of medium and large size (up to 160 m ?). This equipment has a very shallow depth (18-25 cm), which allows you to fit into the design space. Columns of air conditioning in appearance like a refrigerator or cupboard and placed on the floor. This high capacity air-conditioning (14 kW) from the upper part of which is blowing cold / warm air. It is commonly used in large rooms, restaurants and showrooms. In suburban homes it is practically not used - because of the awkwardness (which affects the design) and noise. Outdoor unit air conditioners cluster hidden behind a false ceiling, and its outer part - decorative lattice with distributive blinds - located at the ceiling, and corresponds to the size of ceiling tiles. Pluses cassette air-conditioner: silence and invisibility (visible only grid ceiling), so that fits in any interior. In addition, the cassette air conditioner evenly distributes the air flow in four directions, which is very effective for cooling large spaces. Installation of air conditioners usually cluster is held during the work on the suspended ceiling. Indoor unit channel-type split-system hidden in the ceiling (if large - is in the back room). The indoor unit of the system of ventilation ducts in the ceiling space air is supplied to multiple rooms through decorative lattice (diffusers) installed in the ceiling. Hence the name - channel. In this type a few pluses. It is negligible in the interior - in the room are visible only grid supply and exhaust ducts. Channel power conditioners - 12-25 kW, which is sufficient to cool 4.5 rooms. In addition, most models allow mix with fresh air from the street within 30% of the transmitted volume. However, the installation of "kanalnika" - it is very complicated, which requires highly skilled installers and serious elaboration of the project - must be accurately calculate the cross section ducts, or in one room will be cold, and the other is hot. If you always cool / heat a few rooms (two to seven), will require installation of multi-split-system. From the usual split-system, they differ in that they have not one but several indoor units with one outdoor. In most cases, the internal components are mounted on the walls of the premises, but not eliminated options with a free layout of blocks (floor, channel, cassette) on different capacity - depending on the particular premises. Installation of multi-split-system saves space on the outer wall of the building and not spoil the appearance of the house with numerous drawers outdoor units. However, we must be alert to the possibility that the failure of the external unit will cease to operate all domestic. Additional features modern split systems can be inverter and NON INVERTER. NON INVERTER model works on the principle of "turn-off." That is, if the system is programmed with the owners for permanent maintenance of the room 24 ° C and the ambient temperature reached 30 deg; C, air conditioner will cool the air. In establishing a set temperature the compressor turns off. Once the temperature begins to rise, the system will again come into effect. Inverter system, as opposed to NON INVERTER operate continuously. They automatically adjust the temperature in the room - after reaching the desired temperature air system is turned off, but only reduces performance. To cool or heat the room, the system first runs at full capacity, but as we approach a given temperature Power will gradually decrease. After reaching the desired temperature air conditioning system maintains efficient operation with minimal power consumption (thus saving up to 30%). Therefore, the inverter model no inrush current, there is no sharp increase in fan speed and noise produced by them. By the way, because of the minimal noise (around 22 decibels) inverter model, experts recommend installing in the bedrooms. The advantages of this system also include long lifetime, as exhausting excluded compressor constant switching on and off. There are also ventilating ventilation system, which, unlike air conditioners only cool the air, produce a replacement. Supply and exhaust system - it's the same split-system channel type, but with the difference that the air force is taken and removed from the premises. In the case of forced ventilation air flow is the outdoor unit "is taken" off the street, cleaned from dust, heated / cooled and served in the room. Ventilation, on the contrary, remove from the premises polluted air and draws it out. The best option - the installation of the house balanced ventilation when the air is blown into the room air-supply system (100% mix with air), and removed the exhaust. The system can be created either on the basis of independent subsystems of inflow and exhaust air (with their own fans, filters, etc.) or through one of the installation, working as a tributary, and on the hood. However, their performance should be identical to avoid differences of air pressure inside and outside, which leads to the effect "slamming doors". The main drawback of forced-air ventilation - the noise that is created by a duct. To get rid of him, is introduced into the design mufflers or use acoustic boxes. Dried and moisturizes iron, stove, television, monitor, light - all heats and dries the air. However, the main role in this play space heaters and air-conditioning system - air in this room contains from 20 to 35% moisture, whereas for the comfort a person needs humidity level of 40-50%. Dry air is bad for well-being of slum houses, and in particular - on the health of young children. In addition, dry air has a negative impact on domestic plants and animals, as well as the appearance of wooden furniture, flooring, musical instruments, artwork, etc. Humidifiers - special weather instruments, allowing to reach the required level of moisture in any room. Experts recommend installing humidifiers around radiators - the humidity quickly spread under the influence of warm air. Humidifiers come in several forms: traditional, ultrasonic, steam. There are also moisturizers, cleansers, in which the air from dust and dirt is cleaned through filters. High humidity in the room also did not affect positively on the inhabitants of a country house. For example, high humidity causes corrosion in the basins and decay of metals in the pantry and private libraries leads to mold and property damage. To solve this problem, use dehumidifiers - devices designed to control humidity in areas with high humidity levels. Dehumidifiers are used in swimming pools, basements, bathrooms, saunas, baths, showers, drying rooms, etc. Also, these devices are useful in the repair of the premises - for quick drying plaster and paint, when pokleyke wallpaper, etc. The principle of the majority of dehumidifiers such same as that of air conditioners. The fan delivers air from inside the evaporator (radiator with a low temperature), and the air cools, the moisture from the air condenses and flows into the pan. After this dried air is fed to the condenser (radiator with high temperature), where it is heated and fed into the room. Most dehumidifiers equipped with built-in or external humidistat, which automatically maintain the indoor relative humidity necessary. Household dehumidifiers can reduce humidity to 70% of their "performance" up from 7 to 25 liters per day. The higher the humidity and temperature, the faster the dehumidifier removes moisture from the air. Dehumidifier for the pool can handle from 25 to 200 liters a day - it all depends on the model chosen. Purchase and installation With a large choice in the market split systems and complexity of their installation, manually (and correctly!) Select the appropriate model, as well as independently mount it virtually impossible. Conditioner should be chosen, given the mass of nuances: in which room it will be located, the size and location of windows, furniture placement, the intensity of artificial lighting, the number of people in the room and appliances, and much more. Sloppy installation can ruin even the best-quality equipment. In addition, air conditioners require periodic maintenance, which the ordinary layman can not accomplish. Therefore, buy air conditioner is best in a specialized company providing the full range of services (ranging from assistance in selecting the model and ending with maintenance) and has qualified personnel and significant technical resources.
