Air conditioners are becoming more and more part of our everyday life, and it is difficult to imagine a modern home without them. And this is not a tribute to fashion. With the onset of a hot summer, only if there is an air conditioner eco-servis.com.ua Your house or apartment will be more comfortable. Various models are presented on the market, starting from the simplest to modern split systems.
First, you need to decide on the type of air conditioner. If you want to buy equipment for the summer house or you have rented premises where the integrity of the walls cannot be violated, then the best option is a mobile air conditioner. Its advantages include light weight, the possibility of rearrangement and a low price. And the only minus is a flexible corrugated hose with a length of 1,5 m, which must be led out the window.
But the hot air from the street gets back into the same gap. Although there is a way out - to make a hole in the wall with plugs through which this hose will be removed. In winter, when the room does not need to be cooled, this opening can be closed.
For small rooms, a monobloc window air conditioner is intended, installed in a window opening or on the wall so that its rear part goes outside. In these models, it is possible to extract the exhaust air from the room.
Some only cool the air, the more expensive ones also heat it. Due to the ease of installation, they can be installed independently. The disadvantage is that during installation, the thermal insulation in the room is broken, as a result of which air penetrates through the air conditioner, so such models are not suitable for regions with cold winters.
Split systems, consisting of an internal evaporative unit and an external compressor-condensate unit, connected to each other by copper tubes, in which freon circulates and an electric cable is located, are becoming more popular every day. The indoor unit can be placed on the wall, on the floor, on the ceiling and even built into it. The outdoor unit, which is more noisy, remains behind the wall of the building, where the hot condensate is blown by atmospheric air.
Air conditioners of this type work continuously until the set temperature is reached, after which, switching to reduced power, they maintain the temperature regime. This is the so-called inverter system. As a result, energy consumption is reduced by 20-40% compared to a conventional air conditioner.
The power of the split system is usually 2-7 kW and the recommended cooling area is 15-70 sq.m. The temperature can be set with an accuracy of 1 C, it is possible to set the time of turning on or off the air conditioner in advance, and regulate the direction of the cooled air.
In addition to the wall-mounted split system, modern industry produces air conditioners of the cassette type, intended for rooms with suspended ceilings. The lower part of the block distributes cooled air and is covered with a decorative lattice with blinds. Air is supplied in four directions at once. The angle of the blinds can be changed using the remote control. For connoisseurs of refined style, there are prestigious corner air conditioners designed for rooms with an area of up to 35 square meters.
For cooling several rooms at once, a channel air conditioner is intended, the internal unit of which is installed behind the suspended ceiling. Conditioned air is distributed through air ducts, which are also located in the interceiling space. The power of such a unit is 12-25 kW, which is enough to cool 4-5 rooms.
The disadvantage of this system is the impossibility of regulating the temperature in different rooms. For this, it is necessary to purchase valves with electric drives and thermostats for temperature regulation, and these are additional expenses. In this case, it is possible to install a multi-split system, when several internal ones with different power from 2 kW to 5 kW are connected to one external unit. Types of air conditioners can also be different. As a result, each room maintains its own temperature.
There are fixed and set multisplit systems on sale. In fixed ones, a certain set of internal blocks is attached to one external block, which cannot be changed. Usually it is 2-3 blocks. Types of air conditioners are also specified. In the recruitment system, there is a maximum limitation on the number of blocks (usually 4-5) and the total power.
The multi-split system is ideal for saving space on the outer wall, if there is no possibility of installing several external units. The equipment cost of one multi-split system or several split systems is approximately the same, but in the latter the cost of installation increases due to longer communications. The disadvantage of multisplits is that in the event of a breakdown of the outdoor unit, the entire system will stop working.
In order for the air conditioner not to work to the point of wear and tear, it is necessary to correctly calculate the power required for cooling. Usually it is 2 kW - 8 kW, but it should not be confused with the power consumption, which is approximately three times less. It is better to pay attention to energy efficiency, denoted by EER. The higher this coefficient, the better. Air conditioners with high energy efficiency are often used to heat the room.
This function is denoted by SOR (thermal coefficient). The value of SOR should be higher than EER. This is due to the fact that during the operation of the air conditioner, during heating, the compressor transfers additional heat to the freon. According to energy efficiency, air conditioners are divided into categories, which are denoted by the letters A (the best) and G (the worst).
And the approximate power calculation consists in the fact that with a room height of 3 m for every 10 square meters, 1 kW is needed.
Most modern air conditioners can not only cool the room, but also heat it in winter. But such models are more expensive. The heat taken from the outside air and heated in the air conditioner is pumped into the room, i.e. the outer and inner blocks seem to change places.
But it should be remembered that air conditioners with a heat pump work only at an air temperature not lower than zero. In order to be able to heat the room at a temperature of -20 C, a compressor crankcase must be built into the air conditioner, which affects the operation of the fan. But it is not economical to use such an air conditioner, because Ego should be warmed up 1 hour before work. In addition, a decrease in the air temperature outside reduces the power of such an air conditioner.
Modern models have the ability to automatically clean filters in the internal unit. After a certain time of operation, it stops working and the filter cleaning period begins. If necessary, this cleaning can be carried out from the control panel.
Currently, there are so many models of air conditioning equipment that the process of choosing an air conditioner is quite complicated. But after weighing all the "pros" and "againsts", having studied a lot of literature, you will acquire such a technique that will please you with its effectiveness and will last a very long time.
