Which Best Ducted Air Conditioning System Are You Investing?

ActronAir vs Panasonic vs Mitsubishi – Which Ducted Air Conditioning System is Best?

When it comes to determining which ducted air conditioning is best for you, there are many factors to consider. Whether you’re building a new home/building or renovating your current one, there are a lot AC brands to choose from such as ActronAir, Panasonic, and Mitsubishi.

How To Evaluate An Aircon: The Metrics

How do you choose which aircon to invest in? Well, first you need to understand how to measure performance. Key performance metrics include the following:

  • Energy Efficiency Ratio (EER)
  • Seasonal Energy Efficiency Ratio (SEER)
  • Integrated Energy Efficiency Ratio (IEER)
  • Heating Seasonal Performance Factor (HSPF)
  • Coefficient of Performance (COP)
  • British Thermal Unit (BTU)

Firstly, it is vital to understand the term “British Thermal Unit” (BTU), which is “a measure of the heat content of fuels or energy sources” according to the EIA. They note “It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit).”

The Metrics Explained:

The Energy Efficiency Ratio (EER) is an energy performance rating representing a ratio of cooling output in BTU to electric energy input in watt-hours within set conditions. An EER of at least 12 is generally excellent for portable AC units. The Seasonal Energy Efficiency Ratio (SEER) is similar to the EER but instead accounts for varying outdoor temperatures such as through summer and winter. To give you an idea, AC systems require a minimum SEER value of 13.

For commercial and industrial settings the most reliable metric is the Integrated Energy Efficiency Ratio (IEER). It is calculated using the AC unit’s EER at varying load percentages. Heating Seasonal Performance Factor (HSPF) is the counterpart of SEER in the unit’s heating mode. An HSPF of at least 8.2 is an ideal rating. Lastly, the Coefficient of Performance (COP) is a ratio of heating and/or cooling output to energy input. The COP value is calculated by averaging all the previously mentioned metrics; the greater the COP value is more energy efficient it is. Generally, this value lies between 2.3 and 3.5 for aircons. However, you cannot compare the COP for aircons that run on different energy sources i.e. electricity, gas or oil.
