What You Need to Know About Inverter-Type ACs

What are Inverter Type AC units?

Inverter Type ACs are the latest in air conditioning technology, which use 20-40% less energy to operate than conventional AC units.

Why?

They are equipped with special compressors which operate at different speeds based on the room temperature or running cycle; conventional AC units are either off or running full speed.  As with any motor, whenever possible, running at lower speeds means burning less power and thereby saving energy.  This also implies that the compressors work less, causing them to last longer than conventional motors.

How?

Inverter type AC units convert the conventional power from your home (AC) into DC, to then recreate frequency and amplitude variable power to drive the compressor and evaporator units in a controlled electrical environment.

What is ‘SEER’?

SEER stands for Seasonal Energy Efficiency Ratio.  In short, it’s the energy efficiency of an AC as the MPG is to an automobile; the higher the SEER, the more energy-efficient the AC unit will be.  We suggest the use of AC units in the order of SEER 16 to 22; higher SEERs are difficult to justify their added cost as compared to their energy savings.

What is ‘BTU’?

BTU stands for British Thermal Unit, and basically it’s the AC unit’s rated cooling/heating capacity.  The most common BTU sizes for residential homes are 12000, 18000 and 24000, or the equivalent to 1, 1.5 and 2HP.

NOTE: If you own or are planning to use your AC unit in a renewable energy powered system, it’s obvious that the more you can save on power consumption, the more cost-effective or efficient your system will run.  But more importantly, knowing that these units do NOT have “hard electrical starts” as conventional units do, means your RE system components will not be unnecessarily stressed, improving the life of your inverters and battery banks.
