What type of refrigerator compressor is better

Refrigerators belong to the category of necessary household appliances in the house. The refrigeration equipment market is represented by many different models that differ in appearance and technical characteristics.

The design of the design carries a purely aesthetic load, and the technical parameters are directly related to the quality of the refrigerator, its durability and efficiency. In addition to the fundamental differences in the compressor arrangement, refrigeration units are divided into single-compressor and two-compressor. It is important to distinguish between these parameters to select the optimal model.

Technical characteristics and features of a refrigerator with one compressor

Compressors in the refrigerator are of several types:

  • Ordinary - were installed in the very first units and are obsolete at the moment. The simplest pump shakes freon, forcing it to move through the tubes. It has two modes: "On" - maximum load and "Off." - full shutdown.
  • Linear - in the magnetic coil in the horizontal plane moves the piston of the pump, which pumps the pressure of the cooling agent in the tubes. Like the previous view, it can only work at full power or shut off.
  • Invertor - a motor with a coil that creates freon pressure in the system. It differs from the others in the smoothness of the work provided by the controlled shaft speed. The engine does not turn off, but simply reduces power.
  • Linear inverter - a magnetic coil with an adjustable frequency of the piston speed. The most silent and economic design.

The temperature sensor measures the number of degrees in the refrigerator compartment and instructs the relay to turn the compressor on or off. The last two types in the list are not permanently disabled, therefore the sensor signal about the temperature increase informs the compress about the need to only add power, and not reach the peak load, unlike the first two.

Having dealt with the basic structure of the compressor, you can determine the features of the refrigerator with one compressor. In such models, only one pump is used, even if the device is two-chamber (refrigerator and freezer). During their cooling, a single compressor works, which does not share the need to lower the temperature in a particular chamber, which means that it works constantly in both. Such samples do not have the ability to separately enable freezer or refrigerator compartment cooling.

What is the difference between a two-compressor refrigerator

There are refrigerator models on the home appliance market where two compressors are installed. Such samples have several pumps, each of which is responsible for maintaining the required temperature in a particular chamber. Freezer works separately, refrigeration - separately. Such a system allows faster cooling of products, as well as the convenient ability to turn off one of the compressors if it is not necessary to use it, for example, when a family goes on vacation.

Why, according to consumers, one compressor is better than two

Many buyers believe that one compressor in the refrigerator has advantages over similar models with two pumps, in that the former are more economical than the latter. The conviction of people in less noise emitted by a refrigerator with one compressor also speaks in this favor. Both of these observations may be objected to the following:

  • One compressor cooling both chambers does not choose which one to pump more cold into, which means it always just works at maximum. Perhaps the freezer at the moment does not require freezing, and warm foods were put in the refrigerator, but the compressor will still turn on by order of the thermometer and begin to cool both chambers. In addition, in the long absence of owners in the house, with the freezer turned on, the refrigeration compartment will also be cooled.
  • Modern linear inverter compressors are almost silent and operate without sudden starts, rattles and vibrations, so the number of installed compressors does not greatly affect the noise level.

An important parameter when choosing is the cost. Now on the market you can find inexpensive models of both types, but devices with two pumps will still be more expensive than models with one pump. Here, only knowledge of the expectations from the operation of the refrigerator will help. It is impossible to say unequivocally which one is better. You must first decide on the tasks that the refrigerator should solve and only then choose a model.

What usage parameters affect which compressor is best to buy a device with

For the right choice of model of the refrigerator, you need determine the necessary parameters:

  • The volume of chambers, the number of stored products - a large family requires a large amount of food that needs to be stored in the refrigerator, which means that it must cope with the rapid cooling of a large load of products. The reverse side - if a person lives alone, he does not need a large amount at all.
  • Frequency of prolonged absence from home - if the owner has been absent for a long time on business trips, but wants frozen food to be expected upon arrival, it makes sense to consider a two-compressor refrigerator that can provide cooling only for the freezer. Refrigeration at this time will be turned off in order to save electricity.
  • Electricity load - if small capacities are suitable for the house, and the load on them is high, then it is better to look at the inverter type of compressor. They are sensitive to voltage surges, but they create less load on the wiring. The differences can be leveled with an additional voltage stabilizer or protect the refrigerator with a separate "automatic" in the electrical panel.

Which is better - a refrigerator with one or two compressors, if you plan deep freezing of products

When deep freezing is planned, maximum power is required from the compressor. In order to effectively freeze a large amount of food, it is better to use a refrigerator with two compressors, because regardless of the temperature in the refrigerator, the compressor responsible for it in the freezer will focus on lowering the temperature in the negative compartment.

How the frequency of power outages is harmful to the device

Like any electrical appliance, refrigerators are harmful to energy drops. Strong power surges can damage the compressor. Its replacement is an expensive pleasure. Therefore, it is better to secure its operation by the methods described in the previous paragraph.

Important! If the room where the freezer will be installed is bad wiring, it is better to replace it with a new one. This will cost less than a possible replacement pump. It is also always important to remember the need for grounding - the refrigerator case is often made of metal and can easily be shocked by accidental contact, in the event of a malfunction.

Reference! An interesting argument in favor of the two-compressor unit is the following argument: in the event of a malfunction of one of the pumps, the second one will continue to work anyway, so the refrigerator can still be partially used.

Choosing a model by the number of products to be stored in the refrigerator

If there is a need for constant storage of a large number of products, then it is better to purchase an apparatus with two compressors. They will allow you to more effectively cool food, thereby extending its shelf life. This is the paramount task of the refrigerator, which means that it is important that it copes with it.

If the unit is not loaded "to the eyeballs", and used by a small family, then a single-compressor model is quite suitable. The main thing to remember is that the more products are loaded into it, the higher the temperature there and the more the pump will have to work to cool the chambers. Therefore, competent loading of the compartments will allow efficient use of models with one pump.
