Compressor for split air conditioner is one of the most important working bodies. And the most expensive. Its price is sometimes 75% of the cost of the entire device. Read on what compressors are installed on the best split-system air conditioners.
Functions and types of compressor split air conditioner
A compressor is required to compress the refrigerant and increase its pressure and temperature.
This is the main element of any air conditioner or refrigerator. In an air conditioner with split system, the compressor is located in the outdoor unit. The average compressor life is from 7 to 10 years.
According to the method of action and power, the following types of compressors for split-system air conditioners are distinguished:
- rotational;
- screw;
- spiral;
- piston
- centrifugal.
In household and semi-industrial air conditioners, split compressor systems are most often installed rotational tight. The power of such installations does not exceed 9 kilowatts.
Centrifugal and screw compressors are used in very powerful and productive plants. They can be disassembled and repaired, unlike the rest, which can only be replaced.
Piston compressors
Inexpensive split-type air conditioners are usually equipped with reciprocating compressors. The low cost indicates the low reliability of such systems. Knowing this, the manufacturer gives a guarantee on his brainchild for only 12 months.
The system is outdated and does not withstand the power of modern units, however, acquiring the cheapest split air conditioners, you can run into such a design. The unreliability and low efficiency is explained by the intense friction to which the internal parts of the device are subjected. All parts wear out much faster. Already in the second year of operation, owners will notice that the piston split air conditioner cools the air much weaker.
If the refrigerant pressure is exceeded, the parts experience even greater loads, at the risk of breaking.
Experts recommend buying a split-system air conditioner with a reciprocating compressor to choose a model with a good power reserve.
Thus, the entire resource of the equipment will not be developed and its service life will somewhat extend.
Rotary compressors
They are very easy to produce, they are lightweight, inexpensive and very powerful. Therefore, rotary compressors are equipped with most modern air conditioners with split systems.
The best split-system air conditioners receive a compressor that changes the speed of the engine, that is, the cooling capacity changes.
