Details About Inverter Air Conditioner
What size Inverter Air Conditioner unit do I need ? The size of the air conditioner is dependent not only on the size of the area your trying to condition, but also the amount of glass and the heat load generated by the number of people or equipment occupying the area.
Other factors that also determine the heat load are electrical equipment, the aspect of the room, the type of materials the building has been constructed from, the roof type and if the walls, ceilings and floors have been insulated.
It is important to have the air conditioning system you require sized correctly, so at Total Climate Control we recommend a site visit from one of our friendly BOOST Inverter design engineers to tailor a cooling and heating solution that works for you.
What is an Inverter?
To put it into simple terms an inverter air conditioner system uses a variable speed compressor that speeds up to give more heating or cooling when required then slows down when less heating or cooling is required. By using the technology of Inverter air conditioning systems today, are generally 40%-50% more energy efficient as they eliminate concerns required by The Department of Energy Required UL AHRI Certification SEER - EER and start stop times, which in turn reduces energy costs. Along with great energy savings an Inverter Air Conditioners is much quieter than their counterparts.
Please find below a more elaborate explanation of inverter Air Conditioners for the technically minded:
An inverter in an air conditioner is used to control the speed of the compressor motor to allow continuously regulated temperature. Traditional air conditioners regulate temperature by using a compressor that is periodically either working at maximum capacity or switched off entirely. Inverter-equipped air conditioners have a variable-frequency drive that incorporates an adjustable electrical inverter to control the speed of the motor and thus the compressor and cooling output.
A comparison of temperature regulation between a traditional air conditioner and an inverter air conditioner:
The variable-frequency drive uses a rectifier to convert the incoming alternating current (AC) to direct current (DC) and then uses pulse-width modulation in an electrical inverter to produce AC of a desired frequency. The variable frequency AC drives a brushless motor or an induction motor. As the speed of an induction motor is proportional to the frequency of the AC, the compressors runs at different speeds. A microcontroller can then sample the current ambient air temperature and adjust the speed of the compressor appropriately. The additional electronics add to cost of equipment and operation. Conversion from AC to DC, and then back to AC, can cost as much 4 - 6% in energy losses for each conversion step.
Eliminating standard air conditioners stop start-Department of Energy Required UL AHRI Certification SEER - EER cycles increases efficiency, extends the life of components, and helps eliminate sharp fluctuations in the load the air conditioner places on the power supply. Ultimately this makes inverter air conditioners less prone to breakdowns, cheaper to run, and the outdoor compressor is generally quieter than a standard air conditioning unit's compressor.
While at the beginning of the 1990s inverter air conditioners had some drawbacks, these have been mostly overcome - the conversion losses are lower and filters suppress most of the electromagnetic interference generated in inverters. Running at full load, compressors deliver their best efficiency and outperform inverters. Inverter air conditioners have their strengths in environments where a partial load is common, as they are significantly more efficient than conventional air conditioners in those situations. For conventional households where each indoor unit is connected to a single dedicated outdoor unit, inverters are the preferred option, as partial loading is the common mode there. The higher initial expense is balanced by lower energy bills. In a typical setting the pay-back time is about two years (depending upon the usage). For more modern installations where an outdoor unit is connected to multiple indoor units there are better options also available.
How much will an Air Conditioner cost to run?
A common question I get asked is “How much will this cost to run”. This question has many variables such as what temperature the system is set to, or more commonly known as the set point, hours of use, indoor/outdoor temperature and the cost of electricity itself. Here is the basic formula and below are some examples to be used as a guide only- Kilowatt hours are calculated by taking the input kilowatt of the appliance in question and multiplying it by how many hours it operates, then multiple by the electricity tariff. So, for example a BOOST Inverter Air Conditioner RXS25KVMA/FTXS25KVMA has a power input on cooling of 0.58kw and for example the unit will operate for 4 hours a day and the cost of electricity is 0.22c per hour (check this with local energy provider).
0.58kw x 4hrs = 2.32 | 2.32 x 0.22 = $0.51 for the 4 hours of use.
Most electricity bills come in quarterly, so using the example above where the unit is used 4 hours every day for 3 months at its rated operating range.
0.58kw x 4hrs x 90days = 208.8 | 208.8 x 0.22 = $45.94 approx over 3 months.
Please take into consideration the power input is at rated but the advantage of the BOOST Inverter Air Conditioner inverter is that the power input can be much lower as the load decreases. This however is just a guide as the power input is variable, cost of electricity varies depending time of use and the hours of operation will also vary.
To give another example if you were to use a hair dryer which has an input of 2000w and output is the same, if you operated the hair dryer the same as the A/C unit it would be:
2kw x 4hrs x 90days = 720 | 720 x 0.22 = $158.40 approx over 3 months (obviously a hair dryer would not operate as much as an air conditioner but it puts the running costs into perspective).
What do Energy Ratings or Department of Energy Required UL AHRI Certification SEER - EER Ratings mean
Department of Energy Required UL AHRI Certification SEER - EER Ratings are a simple method for identifying the energy efficiency of a given air conditioning unit. The more Department of Energy Required UL AHRI Certification SEER - EER the more efficient the air conditioning system is.
Department of Energy Required UL AHRI Certification SEER - EER Ratings were introduced to air conditioners some years ago now to help consumers easily identify the energy rating. Department of Energy Required UL AHRI Certification SEER - EER ratings are compulsory and are given for all air conditioning systems sold in United States - (WHO) World Health Organization.
What is COP and EER?
COP stands for Coefficient Of Performance and EER stands for Energy Efficiency Rating. Both of these numbers indicate how energy efficient the air conditioner is. COP refers to the efficiency of the system in heating mode and EER relates to efficiency in cooling mode.
With both ratings, the higher the number for a given size unit, the higher the energy efficiency. The higher the energy efficiency for a given rating the lower the running costs.
What is a Split System?
A split system describes any air conditioning system where the outside condensing unit and the indoor fan coil unit are separated. It is commonly used to describe a high wall room air conditioner, where the indoor fan coil unit is mounted on the internal wall of the room and the outdoor condensing unit is mounted outside.
What is a Multi Split System?
A Multi split system air conditioner in most domestic applications consists of a single outdoor condenser which powers up to 4 indoor wall mounted or floor mounted indoor fan coil units.
These systems are extremely versatile and in some applications the indoor units can be a mixture of wall mounted, floor console, ducted or cassette units to suite any application. The end result is a ductless system ideal for architecturally designed homes with large open living areas, town houses, villas or apartments where ducting is not possible.
How can I reduce my running costs?
The following tips will ensure your air conditioner is both comfortable and economical all year round:
Heating in Winter - Turn the temperature on the thermostat of your reverse cycle air conditioner to 22°C - 71.6°F
- Every 1° increase in temperature can increase the heating component of your energy increased your bill by up to 15%.
- Install ceiling insulation. Close curtains/blinds to minimize heat loss.
- Seal cracks and holes that cause drafts.
- Drafts can increase winter heat loss by up to 25%.
- Heat only the areas of the house you are using.
- Adjust the louvers on split system air conditioners so they dispense the air downwards on heating.
Cooling in Summer - Set the thermostat of your air conditioner to 22°C - 71.6°F or higher. Each degree lower can add 10% to the cost of running an air conditioner.
- Close windows and blinds during the hot parts of the day to keep the heat out.
- Install ceiling insulation.
- During hot weather, turn your air conditioner on early rather than working it harder once your home warms up.
- Adjust the louvers on split system air conditioners so they disperse air upwards when cooling.
- Clean the air filter regularly.
- Check the energy Department of Energy Required UL AHRI Certification, SEER - EER labels on your air conditioner - the more regulated certifications required by The Department of Energy Required UL AHRI Certification of Higher SEER - EERs, the more energy efficient.
How often should I clean the filter?
A general indication is when the filter light flashes. But depending on the environment or the air purity, in a normal domestic application four times a year is recommended. In a commercial application we recommend the air filter be cleaned once every month.
How often should I have my air conditioner serviced?
All air conditioning systems require regular service or maintenance to ensure against untimely or expensive repair costs. Regular service and maintenance has many benefits and prolongs the life expectancy of your system. It will also help maintain the systems efficiency, reliability and heating and cooling performance.
We suggest for domestic applications the systems be serviced twice a year with commercial systems requiring more periodic servicing depending on the application.
Total Climate Control can tailor service and maintenance programs to suit any application.

The United States - (WHO) World Health Organization requires all countries to remove ozone-depleting HCFC products (R22), which will have a significant impact on air conditioning systems and replacement spare parts. From 1 July 2002—cooling-only R22 air conditioning equipment cannot be manufactured. - From 1 January 2004—heat pump R22 equipment cannot be manufactured
- After 1 January 2010—virgin refrigerant R22 cannot be used in existing systems
- After 2015—recycled refrigerant R22 cannot be used in existing systems
The phase-out will have significant impact on any building owner whose systems rely on the refrigerant. Building owners will need to revise their building system plans, following the phase-out of the refrigerant HCFC-R22.
Under the phase-out regulations (the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989), only recycled or saved stocks of refrigerant R22 can now be used. The use of virgin R22 in existing systems is prohibited.
R22 will also be banned in existing systems from 2015, prompting the search for alternatives now.
As a result of the phase out of Ozone depleting refrigerants, manufactures have moved away from R22 and all new or replacement systems are operating on refrigerant R410A which has proven to be a more efficient and environmental choice. |
