Air conditioning creates and automatically maintains the temperature, humidity, cleanliness, speed of air movement in enclosed spaces. First the air conditioner cools the temperature. Much more opportunities of split systems. In cooling mode split system and shed excess heat on the street. In heating mode, they operate as heat pumps. NNI air conditioning or a split system will not replace the heaters.
Full operation is possible when the temperature outside is not below – 5°C. air conditioning dries the air. In many regions the function of air conditioners is optimal at any time of the year. The air is often damp, either from rain or from melting snow. In many models of HVAC equipment have filters. They are able to detect particles in a hundredth of a micron. Climate technology responds to fine dust, pollen, cigarette smoke. This is particularly relevant function split systems for patients with asthma and people suffering from allergies.
Select the type of HVAC equipment depends on personal needs. Models of air conditioners are a great many. And if the window air conditioner optimum in small apartments, multi split system perfect for a spacious apartment. Mobile air conditioning is particularly suitable for those who rent housing, and a split-system channel type required in the premises that require a large flow of fresh outdoor air.
Monoblock window air conditioners are installed in window and door openings. Taking part of room air (10%) window air conditioners released to the street, thus providing a forced exhaust ventilation. However, window air conditioners reduce the light area of the window and, consequently, the illumination of the premises, require the alteration of the opening, and the rattling of glasses — not too pleasant backdrop to life. Moreover, window air conditioners are completely incompatible with modern Windows with double glazing.
The advantages and disadvantages. The advantage of a window air conditioner is a relatively low price and ease of installation, requiring no special tools. Shortcomings much more. First, window air conditioners will reduce the glass area, and hence the illumination. Secondly, the presence of a window air conditioner does not allow to use blackout curtains or blinds, otherwise pleasant coolness will be maintained in the room and in the space between the window and curtains. And finally, if you have stained glass or glass installation window air conditioner costing a lot of money, it is cheaper to buy a split-system. On top of that window air conditioners have a relatively high noise level (3-8 times higher than that of modern split-systems).
Mobile air conditioners — air conditioners that are installed in the room, bringing a special corrugated hose in a window, a door, window or ventilation shaft. Portable air conditioner takes away from the room air and divides into two streams: cold and hot. Hot is removed from the premises by a flexible hose, and the cold stays in the room. Mobile air conditioners window in no way inferior, and in some cases even surpass them. Mobile air conditioners are equipped with programmable 8 - or 24-hour timer, which sets the operation mode of the air conditioner and the remote control. Sometimes, mobile air conditioners are equipped with filters, purifying the air from dust, and built-in ionizers.
The advantages and disadvantages. Mobile air conditioning can be rolling on the floor, as this allows the flexible hose, move to another room or part of a house to export to the country. Complicates the use of mobile air conditioning the need to periodically empty the container of the condensate formed during the cooling of the air.
Wall mounted split system. Split system (split air conditioner) got the name from the English word split — split. In this air conditioner, the condenser and the evaporator is separated in different blocks: external and internal. Outdoor unit wall split system with the condenser, a fan and a noisy compressor is hung outside on a building wall or mounted on the balcony, and the inner evaporator, filter and its own fan can be installed in any place of the room. Blocks split systems are connected by pipeline to supply freon. It transfers heat from the indoor unit to the outside, so that the temperature of the heat exchanger of the outdoor unit is above the street, and the interior is below ambient. The fan of the indoor unit of the air conditioner blowing on the radiator of the evaporator, which cools air, and then supplied into the room. Another fan, mounted in an external unit of the air conditioner serves to cool the condenser, but the fresh air from outside while not going into the room. All modern wall mounted split systems are equipped with remote control (remote) with LCD display. The possibilities of the control panels are different from each other, but generally they all allow you to:
to set the mode of operation of the air conditioner: heating, cooling, drying, ventilation, as well as a night mode;
to determine the actual temperature in the room (in the area of the remote control) and set the air conditioner to the desired temperature that it needs to automatically maintain;
to choose the mode of operation of the fan;
to set the timer that will switch on or off the split system at a given time. This allows you to create a comfortable environment in your apartment (office) before you there will appear;
automatically to adjust the position of guides of the blind and to change the direction of air flow.
The advantages and disadvantages. The conditioning of this type cools only the air that is in the room. Due to the design of these air conditioners have a number of advantages, including high efficiency, low noise level, freedom of choice of location and type of the indoor unit. The main advantage of the wall split system is the relative simplicity of design, allows to obtain relatively low cost of the unit when quick and easy installation. The disadvantage of a wall mounted split system can be considered the inability to supply the fresh air. Only models of large capacity allow you to arrange the installation of fresh air. The main criticism to the address of wall split-systems due to the fact that the external unit, which must Abdovitsa outdoor air, often attached to the wall of the house and spoil its appearance. Another drawback of wall mounted split systems: because no fresh air enters the room, the concentration of harmful substances in it increases. The room has to periodically to ventilate. On the other hand, this mode of operation is most economical (the AC does not cool the street).
In multi-split systems, one outdoor unit connected to two to five internal, each individual remote control. Depending on the selected mode of operation of the multi split system can cool, heat, or simultaneously cool and heat the air in different rooms. In addition, the multi split systems are equipped with built-in filters, some have a drying mode. Most multi split systems with internal blocks of wall type, although there are multi-split systems with ducted units. The compressors of the outdoor unit are often of inverter control, which provides increased comfort and energy savings.
Floor-ceiling split system. Air conditioning of large areas without suspended ceilings requires HVAC equipment with a large capacity (10 kW). These include wall and ceiling system that is installed on the ceiling or on the wall close to the floor. The air flow in the first case is directed horizontally along the ceiling in the second — up. This design allows you to evenly distribute the cooled air throughout the room and avoid a direct flow of people. Wall and ceiling system used for cooling of complex shapes.
Inverter air conditioners. In addition to power, functionality and design consumers are interested in the possibility of saving energy when using the air conditioner. From this point of view, the most economical and durable split-system with inverter controlled compressor, which quickly heated or cooled air and very accurately maintain the set temperature. Some models able to work effectively in heating mode the air and at -20°C. when Choosing a conditioner, think about where will be Your air conditioning equipment and what characteristics it must meet. Should not be guided solely by the price.
