Despite its impressive dimensions, the refrigerator is a sensitive household appliance. Its serviceability depends on the supply of electricity, and in the city, as you know, this often causes problems. As a result, service centers do not remain without work and every day, hundreds, “reanimate” refrigeration units. Is it possible to protect household appliances from "jumps" in the network? Of course! This will help you voltage regulator. And now let's figure out how to choose a voltage regulator for the refrigerator correctly.
Why do I need a voltage regulator?
Regardless of the brand and type of coolness, all refrigerators are powered from the network. But we know perfectly well what a disgusting quality the current "walks" through electric networks and highways. And every day its quality is getting worse and worse.
The main cause of constant voltage drops is congestion of networks, which has long passed the permissible norms. But for a refrigeration unit, it is not the voltage itself that is dangerous, but a “jump”, that is, the length of time between switching off and on. Imagine that turning on a refrigerator requires twice the power( nominal) than indicated in its passport.
The most vulnerable part of the refrigerator is the compressor, or rather the board placed on it, “responsible” for “cold reproduction”.Just think, its repair will cost you at least half the cost of the unit itself. How to avoid unwanted breakdowns? Install a voltage regulator.
Of course, you can say that your house has the latest generation of “frost giant” with built-in protection features, and you do not need additional equipment. You may not need, but it will not interfere with the refrigerator.
Remember, the built-in voltage regulator( if it is, of course, there) does not pull the protection of the refrigerator due to low power. So all these "loud statements" are no more than a simple marketing move to increase sales and raise the reputation of a particular brand. In practice, it is proved that any refrigerator must be connected to the network through additional protection systems. Otherwise, it will not serve you even the warranty period.
How to choose a voltage regulator
You came to the store. How do you plan to choose a voltage regulator for your refrigerator? Do not know? Then listen carefully. The most common mistake people make is buying protective devices based on brand and high cost. Like, more expensive - better. Well-known brand never “put a pig on”. ..
Forget about it once and for all. Today, the price is not an indicator of quality. And by the way, the name of the manufacturer, too. Yes, and leave the appearance of the device immediately to the background, "in people" with him you do not go. What is necessary to pay attention when choosing a stabilizer?
Single phase or three?
For your refrigerator, the stabilizer is protection. But what it will be, the second question. Today one- and three-phase stabilizers are very popular.
The single-phase stabilizer “pulls” only the refrigerator, three-phase will be able to protect several household appliances at once. Before making the final choice, be sure to weigh the pros and cons. Consider whether there is still “serious” household appliances in your home that need protection from voltage drops. If that is not available, it suffices to do with a single-phase device.
Especially since consumer home electrical networks often have only one phase, so buying a three-phase stabilizer, which is several times more expensive, simply does not make sense.
The most important criterion - power
The most important indicator of the efficiency of the unit is its power. It should be 20% higher than the capacity of the refrigerator itself. If the device has to "pull" any other appliances, you need to calculate the total amount of power of all connected appliances and add to it 20% of the total amount you received.
A 220v voltage stabilizer for a domestic refrigerator is not difficult to find. Yes, and calculate the necessary parameters, too. And for this there is no need to be a great mathematician. Moreover, the manufacturer took care of you in advance, and took over all the calculations. The main thing is to know the power of your refrigeration unit( available in the passport).And based on this data, buy an inexpensive but effective stabilizer.
Types of Stabilizers
Voltage stabilizers are:
- Electromechanical. Such devices are used only where voltage drops are the exception rather than the rule. Regulated input and output voltage by means of electronics.
Pros: high accuracy.
Disadvantages: low voltage conversion rate.
- Triac .Expensive pleasure with a lot of advantages, which is controlled by means of regulating levers with proximity switches.
- Relay. Power control occurs through relay switching activated by electrical pulses.
Do you need a stabilizer, of course? But do not forget that his purchase is an investment that will save you from troubles and big expenses in the future.
Each room has its own stabilizer.
. The stabilizer purchased for an apartment will not be suitable for giving. Country equipment is mainly equipped with an asynchronous "insidious" engine. No, the engine itself is not terrible. Its start is terrible. So in order to start up some 1.3 kW pump, you need twice the power, that is 2.6 kW.
Therefore, when choosing a power stabilizer to give, you need to find the sum of all household items that will be connected to the device and add another 45% of the result to it. Believe me, here it is better to choose more in order to surely protect your home appliances ort breakdowns.
With home stabilizers easier. Especially if you plan to buy a device exclusively for the refrigerator. Well, if you own a private house, when connecting a stabilizer, you need to take into account the network phase as well.
It is easy to measure It with the help of special devices that plug into the outlet. Analyze the data, find the errors, measure the power of all household appliances and go shopping.
