Management fridge door opening and installation features
Today, it is simply impossible to imagine a modern house, apartment, office, and even without such an important functional component, as a refrigerator. Technological developments leading manufacturers in the field of household appliances downright dazzling ordinary buyer. A variety of models, their functionality and design solutions presented so pervasive that the question of how to choose a good refrigerator, a layman is difficult to answer. But let's try to deal with this difficult task at first glance. So, what should you look for when choosing a refrigerator?
Free-standing and built-in refrigerated cabinets
To begin with, it should look like the modern equipment to properly fit into the size and interior of your kitchen. Refrigerators are both free-standing and embedded in furniture design. Of course, they have fundamental differences, which will be mentioned below.
Freestanding models are different from their counterparts embedded in the first place, easy installation and deployment. They are quite mobile, allowing you to rearrange them if necessary, and also have a wide selection of colors and striking flight of design ideas.
Refrigerators, installation of which involves installation of components in the kitchen units or special niche called embedded. Their main characteristics and undeniable advantages - is the preservation of the overall interior design kitchen and a substantial savings of its useful space. Here are just a selection of the necessary in this case, the model will require you some time-consuming and patience.
It must be said that free-standing and built-in refrigerators do not differ in their functional characteristics. The difference may amount to a price - embedded equipment is always more detached. This also applies to the rest of the equipment for the home.
The design and size of refrigerators
We now turn to such an important issue as the size of the model and its design. When choosing a new refrigerator and assuming install it in place of the former, consider not only the dimensional characteristics, but also the direction of the door opening. Also it is necessary to determine the possibility of trouble-free delivery of the selected model to the apartment because of its size relative to all encountered on the way doorways: entrance of the building, the elevator, the apartment and, most importantly, food.
Under the structure of refrigerators meant an amount it doors. In this regard, the model may be:
one-door (one common door in refrigerators and freezers);
two-door (one separate doors to refrigerators and freezers);
mnogodvernymi (there is a third additional door to the zone of freshness).
According to the number of door models it can be judged on how many cameras there.
In refrigerators with one door usually one camera. But they found the model number and options with a separate small freezer. Single-door refrigerators in height usually not less than 85 and not more than 160 cm, width of about 55 cm and a depth of 60 cm. The volume of no more than 250 liters. Refrigerator such dimensions better viewed as a summer residence, office or hotel options and it is fine the owner of a small-sized apartment or small house with a small kitchen.
The most common in our models - two-door height and a half to more than two meters and an average volume of 350-400 liters, and in some cases to 600. In such models are usually two mutually independent chambers - refrigeration and freezer - a separate door for each.
There are three-compartment options with so-called "zone of freshness", which creates an optimal temperature conditions, stopping the process of the growth of bacteria. They can store food for a long time without freezing. Agree, it is very convenient technological boon for the modern home. There is also a large and very roomy model consisting of several refrigerators and freezers.
Departments in domestic refrigerators are assembled in one of the following options:
A large freezer is at the bottom, under refrigeration. This so-called "European" option.
A small or medium-freezer is located above the refrigerator. It looks like "Asian" option.
Refrigerators and freezers are adjacent to each other along the entire height of the refrigeration unit. Option Side-by-Side, or "the American."
As a rule, the top location of the freezer, it looks like the inside of a hollow compartment. If it is down, it is usually divided into several boxes or containers - it's made for greater capacity.
Classes energy consumption of refrigerators
One of the most important criteria when selecting a refrigerator is a class of its power
. Since there is evidence that about 30% of the electricity consumed in the home accounts for this particular household appliances, the question of efficiency is always important for consumers and producers
. Until recently, the market refrigerators most convenient in this respect considered as a model class A
. The second place was held machinery Class B, and the third placed the least cost options - the class consumption G
. This distribution existed for a long time and seemed firm
. But in its endless pursuit of perfection of the market leaders of refrigeration equipment presented to the consumer of the new technique of the sample - the class A + and A ++
. And now it is considered to be the most economical in terms of energy consumption
. But who knows what new and exciting solutions in store for us tomorrow? Yes, choose a good refrigerator is not easy!
Classification of refrigerators for climate classes
And did you know that the refrigerator, except for the levels of power consumption, there are also climate classes? What is it? Everything is explained very simply. These classes mean by a clearly defined design features in the production of refrigerators, allowing the technique to work effectively in different climatic zones. Now, 4 major climatic class:
Class N - it means that the equipment is designed to operate in a normal temperate zone with a range of temperatures 16 - 32 ° C;
class SN - implies operation in moderately cold climate zone with temperature control 10 - 32 ° C;
Class ST - optimal for humid tropical climate where the temperature is 18 - +38 ° C and high atmospheric humidity;
Class T - provides for work equipment in the dry tropics and air temperature up to + 43 °
This separation makes it possible to select the refrigerator, the most appropriate way or another climatic characteristics of the country in which it will operate with the highest impact and lowest power consumption. Appliances all four classes differ from each other structural features of the compressor, condenser and insulating characteristics. However, the device provides many of today's refrigerators and mixed double the value of their climate-Class - SN-ST or N-ST. So manufacturers have significantly expanded their use temperature limits.
Each modern refrigerator - quality compressor!
The main role in this classification, and indeed in the refrigerator, playing his heart - the compressor. On how the quality of this important mechanism, depends on the life of the equipment, and its main function. It is through the compressor coolant (coolant or freon) performs a closed loop inside the sealed system, thereby cooling the refrigerating chamber. The most common one compressor model, in which both chambers are cooled at the same time. Although, in the presence of the compressor in two independent cooling circuits, the temperature mode and in another of the chambers may be different. Opening the door of the compartment can be sure that the temperature in the other remains unchanged - it saves electricity. Single-compressor refrigerators of this type are the brands Liebherr, Bosch, Siemens.
The two-compressor models are available not just different temperature chambers, but they are independent of each other work. This is convenient to defrost the refrigerator, because there is no need to worry about the safety of food in the refrigerator. But if you happen to damage one of the compressors, the repair of this model can not do much more than fix one compressor.
After contact with warm air in the chamber of the refrigerator, when we open and close it doors, the temperature rises there. This can not but affect the safety of products. That is why just need to keep the temperature in the cells immediately return to the original performance. To this end, manufacturers of refrigerators have developed three basic cooling and thawing:
static;
vented;
no frost, that is, without frost.
The static system, the so-called "weeping wall", we know well, because pieces of ice that form on the back of the inside of the refrigerator when the compressor is running, it is visible and tangible. When the compressor is stopped, the frozen crystals turn into drops and flow down the drain, then into a special container and already there are vaporized cooling element chamber. Such a system is called the dropping defrosting. Refrigerators with her very much, and the price is relatively low.
In a ventilated, or dynamic cooling system and a defrost cycle is better due to the fan. It is in the upper part of the system design and is operated so that the air flows along on the rear wall of the refrigerator evaporator. And the compressor and the fan operate simultaneously. The movement of air through the rear wall improves the heat exchange between her and reaching streams.
In some models of heat transfer is accelerated by the fact that the air moves at the heat exchange surface. It is drawn from the chamber and enters the evaporator, which has an independent element refrigeration structure. Such models are defrosted automatically, they do not condensate and the products are always kept in optimum conditions.
No Frost system is arranged in such a way as to prevent the appearance of icicles and frost inside the refrigerator and freezer. The essence of her work lies in the timely removal of humidity and condensing it in the designated places. No Frost system can be in both chambers of the fridge and freezer separately. This technique should be thawed only once a year. Frost Free system provides a complete absence of frost and ice, and does not require defrosting. And it improved model Fresh Frost Free cooling product occurs through the dynamic air Multiflow air circulation in separate chambers (so-called system TwinTech).
What's in the closet?
Among the less important and affecting more comfortable operation to a refrigerator than on its technical parameters and quality, constituting a correct choice, of course, should include how it looks from the inside than its manned the camera. After all, any owner wants maximum convenience and ease of use of household appliances. So what we can see at once, opening the refrigerator door:
different kinds of shelves of plastic, special glass and even wood (for alcohol);
retractable containers;
containers for ice;
boxes for eggs;
compartments for instant freezing;
Shelves on the door;
boxes for storing fruits and vegetables;
built-in light bulb, providing illumination.
All this is a standard set of internal configuration of refrigerators. It may be better or worse in quality, but in principle it is the base for most low-cost and medium-cost versions of its. More expensive models can be equipped with a sensor "open door" built-in monitor for easy control of the TV or music player.
Components same invisible eyes of the buyer, can include an independent battery that is activated in the event of a power failure or breakdown in the refrigerator
. This power supply will ensure the safety of products, and will help accelerate the process of freezing chambers
. Also very pleasant and superfluous addition to the basic configuration will be cooler antibacterial silver ions
. It will help prevent the proliferation of harmful microorganisms in foods, leading to food spoilage and occurrence of unpleasant odors
. Also, do not interfere, and an alarm system that will notify the owner in time Bad change of temperature indicators in the camera or let you know if there is an emergency shutdown of the refrigerator
. There is a function such as automatic generation of edible ice and a lot of different options that affect the price, but do not change the quality of household appliances
.
Management fridge door opening and installation features
Modern cooler may be mechanical or electronic control. In the first case, the level required under this model, and the cooling is controlled manually by means of a thermostat. Precise temperature regimes for this kind of control can not be set. The electronic system may be equipped with a remote control. If any temperature data set with maximum precision.
Increasingly, there are models of refrigerators, enabling outweigh the door to a comfortable accommodation and operation side. There were also options for two-way door opening from the company Sharp. This exciting feature called Dual Swing Door is a series of models SJ-WM and SJ-WP.
Move the refrigerator allow special rollers. They are located behind and not be seen as the technique itself stands on adjustable legs. If you need to move or relocate the refrigerator, it is tilted back it can easily move in the right direction.
On the main characteristics is perhaps understood. Let's try to clarify what options exist today at specialty stores and online spaces. And there are plenty to choose - price and design are presented for every taste and budget.
Budget models produce such brands as Nord, Atlant, Beko. Samsung and LG also have in its lineup a few Budget proposals.
But in the mid-priced Korean company LG has an opportunity for a wider choice. It is also well represented here refrigerators Slovenian brand Gorenje. Many buyers of household appliances is well appreciated design and build quality offered by this brand models.
The most expensive are of refrigerators Side-by-Side, and regardless of the manufacturer, since they are the most technological, roomy and functional.
We should also be said about the specific issue of design engineering lines. It is worth noting Pininfarina models and very interesting from the point of view of a series of classic interior Retro. Manufacturers thus try to adapt their technique for anyone, not just a modern interior. This desire and different brands such as Toshiba, Zanussi, Whirlpool.
Here, perhaps, and all the important points that had better pay attention to the question of how to choose a refrigerator. It only remains to add something: in the first place Decide how much money you are willing to spend on this purchase. Then think of the size and characteristics of the required model.
A family of two to four people is fine refrigerators up to 300 liters. If family members more, and need an appropriate cooler. It is also the aspect ratio cameras: if your family has fans compotes from frozen berries and fruit, give preference to models with a large freezer. Want to save energy? Choose the technique is not lower than Class A, but do not forget that the back of the refrigerator should be any space for good ventilation. This will not only save electricity, but also significantly extend the life of your cooling equipment.
