Air Conditioners – Comparing Split Systems and Inverters

best split system air conditioner brands

In this article, we look at the advantages brought about by inverter technology.  We do this by comparing non-inverter and inverter split air conditioners.  Our main goal is really to Compare two types of air conditionersthe Split System air conditioning unit and the Inverter air conditioner, but first we discuss some main types of air conditioners to provide a general background for the comparison.

Main Types of Air Conditioners

We may group air conditioners into arbitrary “types” which are characterized by installation and principle of operation.

  • Split System.  This is so called because it “splits” the air conditioners into two.  One part, the cooling part lies outside the wall, which is advantageous because this part is also the noisy component of the system.  The split system is the most commonly known.  It may or may not require a ducting system and is used in most homes.  Ductless split systems are most efficient for use in rooms with open floor plans.
  • Single-Package.  As its name suggests, this type contains all its components in one package which is usually installed in a roof.  This type of air conditioner is commonly used in industrial facilities.
  • Portable Air Conditioners.  This type of air conditioning has a number of advantages.  First, it can be moved easily on wheels to provide cooling to a small space. In addition, it does not require creating a hole in your wall or ruining the beauty of a window. It is also very economical.  Downsides include having to open a window to let out condensate and noise.
  • Evaporative Air Conditioners.  This type provides cooling by making air pass through water-logged pads.  As the water evaporates, it absorbs heat from the passing air, lowering its temperature.  The system works well when the air is dry but is not efficient in humid places.

Comparison of Non-Inverter and Inverter Split Systems Air Conditioners

One issue about air conditioners, no matter the type, is high energy consumption.  To reduce this, manufacturers are now using the so-called inverter technology.  In this section, we try to comparing the difference between split systems and inverters.

With the non-inverter split air conditioners, the compressor almost immediately goes to its full capacity upon switch-on.  Once the required temperature it turns off. It turns on again when the temperature rises.   As a result, there is an on-off cycle which results in peak voltages and wide fluctuations of temperature.  Because the compressor turns on and off repeatedly, a lot of power is used up.  In addition, the system contributes to peak loads.

On the other hand, the inverter split air conditioner uses a microprocessor-based intelligent sensor to check how conditions (temperature) are changing.  This relays the information to an “intelligent” compressor.  Unlike its conventional counterpart, this compressor is able to vary its rpm (revolution per minute) depending on the need for change.  Instead of turning off, it merely reduces its operation.  As a result, split systems that make use of inverter technology have the following advantages:

•    Both startup time and the time to reach temperature required for comfort is reduced by 1/3.
•    Power consumption is reduced by 30%.
•    There is no cycling of the compressor, and hence, voltage peaks.
•    Temperature fluctuations are minimized.
•    Quieter operation because of reduced rpm.

In conclusion, when we compare the split system and  Inverter air conditioners we find the inverter-based models to be more energy-efficient and closer to the green technology required by more environment-conscious consumers.  It is also clear that the advantages of this technology are not limited to split type systems.
