type cooling system
SBIR select the refrigerator, it is important not to forget about its basic component - the cooling system. They can be several:
compression coolers In these devices, a coolant circulates under pressure compressor. These low fuel consumption models that are produced with any dimensions and volume. Nowadays the stores are mainly represented only compressor coolers, and it is about them we will talk more, but to expand the horizons briefly present other options for cooling systems;
absorption deep freezer price in Bangladesh. In the role of a compressor heat exchanger used here that is heated, causing the refrigerant to circulate. Such coolers are made of small and medium sizes, consume more energy than compression, but it can work not only on electricity but also on LPG, which define the scope of its use;
thermoelectric coolers These devices are provided with thermoelectric semiconductor wafers, and the direct current flow through them and cool. Part of plates arranged inside the camera, and the rest - the outside during the operation of the cooling mode, the internal parts cool, external - they warm up. The largest volume of the refrigerator, the excess energy is more remarkable compared to the compression and absorption of the refrigerators so that this method of refrigeration is used only in small refrigerators.
Our colleagues from the TehnoPanorama site as well as who know how to choose the best refrigerator, in your article, tips, and life hacking, and the bonus offer coolers rating by 2018.
Number of compressors
The vast majority of household refrigerators are equipped with a single compressor. Some modern single-compressor refrigerators support the "vacations", which allows a time to transfer the cooling chamber in the economic power mode (which is best to eliminate all products) and the freezer is still working like usual - convenience is obvious.
Refrigerator with two compressors - a convenient and functional solution, but commercially less common. In these devices, the cooling and freezing of the compartment completely independent of each other, so that it can conveniently adjust the operation of each one of them. The level of energy consumption and noise are not very different from the refrigerators with a compressor. If they cost a lot more expensive before, but now the price difference has narrowed significantly.
Many current models are supplied with an inverter compressor. It works all the time, but thanks to a special converter, the intensity of the work are different. Select the optimal way, required to keep the cameras in the refrigerator at a predetermined temperature. In this case, it avoids constant switching inside and outside the device, it is precisely in these phases of work the greatest wear and tears on the compressor. In addition, the compressor inverter coolers with more energy-efficient and less noisy, however, are a bit more expensive than usual.
