Quaternity Energy-Efficient
Extraordinarily Energy-Efficient

The inverter technology, developed by Daikin is a true innovation in the area of climate control. The principle is simple: inverters adjust the power used to suit the actual requirement. No more, no less. This technology provides you with two concrete benefits:

1. Comfort The inverter repays its investment many times over by improving comfort. An air conditioning system with an inverter continuously adjusts its cooling and heating output to suit the temperature in the room. The inverter shortens system start-up time enabling the required room temperature to be reached more quickly. As soon as that temperature is reached, the inverter ensures that it is constantly maintained.
2. Energy efficient Because an inverter monitors and adjusts ambient temperature whenever needed, energy consumption drops by 30% compared to a traditional on / off system.

Daikin develops and optimizes every component within our unique system, making sure each element works flawlessly with the next. Optimal performance is delivered from the time a project begins to the moment of experiencing Absolute Comfort. We use the most up-to-date technology to build products that not only elevate the level of high performance but are equipped with advanced built-in intelligence and flexibility.

Less Frequent Stop/Start Cycles

Conventional air conditioners run compressors at a fixed rate — meaning they must stop and start all the time. As a result, they make lots of noise and use up plenty of energy. Daikin® inverter duct-free systems run continuously at varying speeds, delivering hot or cool air only as needed. This innovative technology allows Daikin to achieve up to SEER 26.1 (up to HSPF 11.0) and generate further energy savings during partial load conditions. What’s more, with continuous operation, the room experiences better dehumidification and the compressor incurs less stress. And because you can control each room separately, you can lessen or even shut down the flow to areas not in use.

Fully optimized for maximum performance

Daikin’s Split and VRV-S® systems operate with R-410A refrigerant, fast becoming the industry standard of the future due to its energy-efficient and zero-ozone-depleting properties. Daikin not only produces R-410A but also optimizes every major system component to work with it, resulting in higher performance, higher EER ratings and lower energy costs.

Inverter technology. What is it?

Inverter technology can be compared to the technology in a car: “The harder you push the accelerator, the faster you go.” An inverter unit will gradually increase the compressor speed based on the capacity needed to cool down or heat up the room. A system without inverter technology can be compared to turning on or off a lamp. Turning on this type of unit will start to run on full load.

Advantages of the inverter technology

1. The system operates at the required capacity, delivering the amount of cooling or heating to maintain the desired comfort condition.
2. Start-up time is reduced by one-third (compared to normal on/off units).
3. Avoids cycling operation of the compressor, thus reduced costly current (amp) peaks.
4. Minimizes temperature fluctuations.

Reduces the energy consumption by one-third (compared to normal on/off units).

The Quaternity system produces more sensible capacity and better dehumidification than a standard split system allowing in some instances a smaller nominal capacity system to be selected.

If we compare the sensible cooling capacity of a nominal 9MBH Quaternity system we can see that it has 164% of the equivalent 9MBH Standard Split Systems capacity and 121% when compared to the 12 MBH.

This is consistent throughout the range of Quaternity and can be seen above when comparing the 15MBH Quaternity to the 15MBH standard Split System. It has 120% of its capacity and the same sensible capacity when compared to the 18MBH.

It is not only the sensible capacity where the Quaternity unit excels. When you look at the moisture removal rate the Quaternity also exceeds most of the equivalent standard split system and one size up.


Thermal comfort is maintained when the heat generated by human metabolism is allowed to dissipate, thus maintaining thermal equilibrium with the surroundings. It has been long recognized that the sensation of feeling hot or cold is not just dependent on air temperature alone.

Humans are sensitive to humid air because the human body uses evaporative cooling as the primary mechanism to regulate body temperature. Under humid conditions the rate that perspiration evaporates from the skin is lower than it would be under dry conditions. Because humans perceive the rate of heat transfer from the body rather than the surrounding temperature itself we feel warmer when the relative humidity is high than when it is low.

Under conditions of high humidity, the evaporation of sweat from the skin is decreased and the efforts to maintain an acceptable body temperature may be significantly impaired which causes us to feel sticky or start to sweat.

DEHUMIDIFICATION without lowering the temperature

Dehumidification has many beneficial effects on comfort levels. During the summer, where there is an infiltration of high humidity ambient air, even during mild ambient conditions, the room can feel very hot and stuffy. With "Quaternity controlled dehumidification" the system controls the indoor humidity level by mixing the cool dry air with warm air via its intelligent indoor heat exchanger technology. Also, this feature prevents inefficient overcooling, which helps to save on energy use.

Without Quaternity Room Temperature 77 F Humidity 80%	Room Temperature 77 F Humidity 50%
UNCOMFORTABLE Hot and stuffy with high humidity. Room Temperature 70 F Humidity 45-50%	COMFORTABLE Decreasing humidity while maintaining the temperature increase comfort. How is the Quaternity Dry Operation Achieved?
COLD DRAFT The room is over cooled down to 70 F to achieve satisfactory dehumidification. It results in an uncomfortable cold sensation.	The evaporator of the indoor unit is divided into two sections and solenoid valves are provided in between. In cooling mode, the expansion valve between the condenser and the evaporator works to send low-pressure refrigerant to the indoor side, but in Quaternity Dry Operation, the expansion valve is kept open and a part of the indoor unit is used as a condenser by working the solenoid valve.

Quaternity purifies and removes allergens from the air

Increase indoor air quality with Daikin Flash Streamer technology!

Quaternity reduces the presence of the following substances much faster than other technologies: Virus Bacteria Mold

An industry first- Daikin’s Flash streamer air purifying function removes both allergens and adjuvants from the air you breath.

Flash Streamer technology is proven to deliver over 1,000 times faster purification versus normal "plasma" type systems.

Air is a transportation device for microorganisms which can cause infections or allergic reactions. A method to reduce the effect of microorganisms is to reduce the amount of time a person is exposed to them. This can be achieved with filtration but sometimes the wrong type of filtration can act as a breeding ground for the microorganisms. This is why Quaternity uses a multi-stage filtration and air cleaning system which incorporates the"Flash Streamer" to break down and decompose the microorganisms in a timely manner.

How is Quaternity Air Purification done?

The multi layered air purifying function powerfully decomposes and removes molecules of allergens and odors. In the indoor unit, the air will be filtered out of dust and pollen and the photocatalytic air purification filter will further decompose odors. The streamer discharges high energy electrons which analyzes, powerfully decomposes and removes molecules of allergens, odors, unwanted bacteria, and other hazardous chemical material by collision with high-speed electrons discharged from streamer unit.

Independent laboratory testing was conducted on the Flash Streamer module in the United States showing the following results:

	The MS2 coliphage was used to simulate a virus; this is an extensively studied method and is used as an indicator of a virus survival. It was released into the space and the Flash Streamer was activated. This was then compared to the same concentration of MS2 and the decomposition with natural ventilation. Within 120 minutes, 95.2% reduction compared to natural ventilation was observed.
	The same test was carried out for E. coli and a reduction rate of 91% was realized.
	The mold Aspergillus, which grows in high moisture climates was tested with the same method and achieved a reduction rate from natural ventilation of 75% over a 90 minute period.

All Daikin systems in North America utilize inverter compressors which can run at speeds greater than that used at nominal conditions. This aids the system performance especially during low ambient heating. This can be seen in the following chart displaying the maximum heating capacity of each system when operating in powerful mode or at the optimum compressor speed.

You can see that the Quaternity system exceeds the standard Split System capacity with results of up to 164%.
