Inverter split systems, outwardly, do not differ from ordinary wall-mounted air conditioners, except for stickers. In fact, there are cardinal differences, but they are all inside.
Many people ask the question, what does an inverter split system mean? This concept comes from the Latin concept “inverto”, which means to turn over, change. It was the change that formed the principle of operation of such compressors, which can operate at a variable speed. Thanks to this, the air conditioner has become more economical. In addition, such a split system can operate at sub-zero outdoor temperatures.
Inverter system: principle of operation and features of the device
The principle of operation of the inverter split system is to regulate the operation of the compressor depending on the air temperature in the room. When the set air parameters are reached, the compressor does not turn off, but continues to work, maintaining the temperature of the air mixture.
Thanks to these features, less noise is generated and the life of the compressor is significantly increased, as there are fewer starts. Running by itself wears it out quite a lot. The thing is that after the compressor stops, the oil in it to lubricate the rubbing parts flows into the crankcase, and when starting, the compressor works for some time in “extreme” conditions.
The main device of a split-system with inverter control is a compressor. Most often it is called the “heart of the air conditioner.” Thanks to him, freon is compressed. In addition, thanks to the compressor, gas moves along a closed pipeline pipeline. But without other devices, the operation of the air conditioner is also impossible.
- Evaporator. It is in it that the transition of freon from a liquid state to a gaseous form occurs. In this case, the temperature of the heat exchanger itself decreases, and, accordingly, the ambient air. The evaporator is located in the indoor unit of the split system.
- Capacitor. In this device, the reverse process of transition from the gaseous state of freon to its liquid form takes place. During condensation, the gas gives off heat to the outdoor air masses.
- Throttle, or as it is also called — a throttling device. It is designed to sharply compress freon in front of the evaporator. This device is located in the indoor unit of the air conditioner.
- Fans. As a rule, there are two of them, one is located in the external, and the second in the internal block of the split system. They are designed to create air currents that blow over the evaporator and condenser.
There are also inverter-type multi-split systems. Their main difference from conventional air conditioners is the presence of several indoor units. They are designed to create comfortable conditions in several rooms at once. Depending on the type of multi split system, it can work perfectly with two, three, and even seven indoor units.
Advantages and disadvantages
Like any climate technology, such systems have their undeniable advantages, but also some disadvantages that will be considered. Advantages:
- More accurate temperature maintenance within the specified limits, compared to conventional air conditioning.
- Lower noise level compared to classical type air conditioners.
- They cool the room much faster, since from the moment of start-up until reaching the set temperature regime they work at full capacity.
- It is much more economical than its classic “compatriots”, due to the absence of peak loads during compressor starts.
- They have a longer service life. This is due to fewer compressor on/off times.
- Can work at rather low outside air temperature.
The disadvantages include their high cost, compared with classic air conditioners. In addition, they are very sensitive to voltage surges, so if there is such a problem in the home, care must be taken to install devices that smooth out power surges.
When Should You Buy Inverter Air Conditioning Systems?
There are several main reasons why people choose such climate technology for themselves.
- One of the main reasons for purchasing such equipment is their increased service life. The abundance of brands, and various fakes confuse most buyers when choosing. And since the split system is already not cheap, many people prefer to overpay for an inverter about 50% of the normal cost of an air conditioner, for its reliability and durability.
- The second reason for the purchase was the economy. It is known that inverter climate technology consumes less electricity.
- This type of air conditioner has a significant reduction in noise levels.
The purchase of such systems should be considered by those who are planning redevelopment in their home, in connection with which, the heat load may increase.
Inverter climate control technology is quite expensive. It certainly has its advantages and disadvantages. In some cases, such an air conditioner is simply necessary, and in some it is a waste of money, so take their purchase and installation seriously.
