Daikin’s dedicated After Sales SupportTeam is second-to-none in providing you with thenecessary coverage for your continued comfortbeyond purchase.9015031924Daikin is the global leader in the HVAC market for over 90 years.*Data presented here are as of 31st March 2017.There are two main technologies to be considered when purchasing a split air conditioner:You always want the best for your home: best TV, best phone etc… This approach should be the same when it comes to purchasing an AC knowing that you will use it almost every day in the year!What is the difference between the various technologies available in the market and why are some of them are more expensive than the others?At first look, both systems offer similar functionality: cooling the air. But, in reality, they are different in terms of compressor drive. Old technology systems use a fixed-speed (Non Inverter) and advanced systems use variable speed (Inverter).»ON/OFF systems, so called "Non-Inverter", used in conventional air conditioners.»Inverter systems, variable speed using the latesttechnology in the air conditioningWhy Inverter?Saving money – we all want that!Do y ou k now t hat c onventional s plits (Non I nverter) are using compressor running at high (maximum) fixed speed all the time? This, combined with the repeated restart of the compressor, will lead the air conditioner to consume a lot of energy. In reality, an ON/OFF system is very inefficient and costly to use.The variable speed compressor of the Inverter split adjusts the power according to the temperature in the room;in simple words, the unit will run at higher speed when you need more cooling and at lower speed when you need less . The electricity you will use then depends on your actual needs, not more! Inverter technology will lower the consumption of the air conditioner down to 50%, so you pay less money for your electricity bills!Tip 2Tip 3Fastest and most powerful coolingDaikin Inverter technology speeds up at the start-up time so the room is cooled down quicker.With Daikin Inverter, the cooling is quick andpowerful, even under extremely high outdoortemperatures.Because Daikin Inverter is smart, it's capableof adjusting the cooling power accurately toyour actual needs. You will have a comfortabletemperature all year round and you will never feeltoo warm or too cold.Eco-friendlyAs you can see all around you, it is all about howwe can reduce our impact on the environmentand reduce the energy use! You can contribute tolowering the environmental impact by making asmart choice for your AC.Longer lifeAs the compressor does not turn on and off all the time and runs at lower speeds and pressures, it makes the AC’s life longer as you will reduce the stress on the compressor, which is the heart of your AC.Quieter operationAs the Daikin Inverter is the most recent technology, it also offers the most silent operation.You will no longer experience disturbing ON/OFF and high fan noise.Tip 4Tip 5Because Daikin Inverter can adjust speed and cooling capacity according to your needs, it uses less energy than traditional AC. Less energy use means lower carbon footprint (CO 2 emissions), which is more friendly to the environment.Also, Daikin uses the latest refrigerants with amazing cooling performance, specially selected for our hot and harsh climate, and less impact to the environment compared to other brands. Refrigerants used by Daikin do not deplete the ozone layer!How long has the inverter compressorbeen used in the world?Inverter AC has been invented in 1980! Today, itis the most selling technology in many countries!First inverter AC has been launched in 1980 butthe spread of the technology over the world onlystarted after 2005 when every market startedto realize the importance of saving electricityconsumption through air conditioning.Today, Inverter is the most selling technology inJapan, Australia, Europe and China.FAQQ2Why do you need Inverter in Middle East?Your cooling needs are different in summer and winter; your AC should adjust to that!The amount of cooling (heating) capacity required depends on the outside temperature and the heat inside the room to be treated. Since the outside temperature varies all year long, the cooling requirements will also vary all year round. Only Inverter has the inner intelligence to adjust the speed to deliver the exact amount of cooling required.Why Inverter is more expensive?Inverter is not expensive! It is a real cost-effective solution.Although Inverter solutions will require a higher investment cost compared to traditional systems, the total life cycle cost is much less and allows you to make real savings throughout the year: inverter units pay by themselves after a short period! When you purchase a unit, the real cost that you pay is not only the unit cost but also the electricity cost that it will consume! To make real savings, you always need to compare the total cost, including the operation cost. Inverter will help you save on your energy bill.Why Daikin is more expensive?Daikin is not expensive!Equipment cost reflects technological expertiseand quality of components used.»Unlike other brands, Daikin does notcompromise on Quality for Price!» Daikin designs and selects carefully all thecomponents of the air conditioner, to ensuredurability and long lifetime.» As Daikin equipment is extremely efficient, initialinvestment is returned back quickly throughlow running costs.» Daikin is a global company with strong localpresence and unmatched after sales support.How can I compare efficiency betweenInverter and Non Inverter?I nverter savings: beyond declared EER or starrating!Today, the only official way to compare performanceof the AC is to look at EER or star rating But what is thereal meaning of EER? EER stands for "Energy EfficiencyRatio"; it will give you an indication on how yoursystem performs at one fixed temperature condition.Using this methodology can be considered asacceptable to assess efficiency of non-inverter systemas it provides a fixed capacity throughout the year andthe average power consumption. Thus efficiency, willbe on average the same over the entire year.The situation for Inverter is different as it has theability to adjust capacity to meet the applicationrequirements. Adjusting capacity is done throughthe regulation of compressor speed; thus powerinput will constantly be adjusted.So, representing efficiency of inverter through EER that is measuring efficiency at full capacity at one fixed condition is not really correct.In order to measure the real efficiency of an air conditioner, the formula must integrate the full weather conditions (all temperatures) at which the system will operate in a certain location. The global trend is towards using "Seasonal Efficiency Ratio" (SEER) as an indicator of the efficiency of an air conditioner: it will measure efficiency of the system at all temperatures and capacity conditions. Different regions have different measuring formulas adapted to their local weather pattern in Europe, US or Japan etc. Now, a Technical Committee of ISO TC86 is working on a SEER calculation standard for Hot Climates that could be adapted to specific cities' weather bin in the region. SEER will then apply to both Inverter and Non-Inverter systems and will greatly help the consumer to know a realistic figure of his estimated yearly energy consumption.What does it mean when I nverter canreach up to 130% capacity?Inverter can modulate capacity from aminimum to a maximum level!You have to remember that inverter is a smartsystem equipped with variable speed motors.It can modulate the capacity output from aminimum level to a maximum level by varying itsspeed accordingly.Inverter can usually cover a capacity range from30% (minimum level; this level can reach down10% on VRV systems) to130% (maximum level)against the capacity declared in the commercialbrochure.For example, Daikin Inverter R 32 split FTKM24PVM can modulate its capacity between 6.5 kBtuup to29.5kBtu while catalogue data is showing24kBtu.When you select your inverter AC, in order toreduce your investment cost, you can selectit based on maximum capacity. However, ifyou select it based on the rated value, theperformance and lifetime will be optimized as theunit will work less time at full load.Is Inverter air conditioner morecomplicated to maintain?Not really!Thanks to the built-in intelligence implementedin the electronics that will allow achieving hugesavings by regulating the compressor, inverterunits are considered more sophisticated systems.Daikin technicians and installers are experienced and extensively trained by Daikin on installation, maintenance and troubleshooting. In fact, cause and type of failure can be faster and easier diagnosed on Inverter thanks to the self-diagnosis function.What is important to remember, to keep your air conditioner lifetime as long as possible, is to conduct periodical maintenance, as per manufacturer recommendations.What about spare parts cost for Inverter? Equivalent parts have similar cost except for the compressor.The main differences in terms of components between inverter and non-inverter are:» Compressors (drive)» PCB (Printed Circuit Board; electronics)The cost of Inverter compressor is of course more expensive than traditional non inverter compressor as it is the latest technology. But lifetime of inverter compressor is estimated to be longer than traditional non inverter: less start / stop cycle and lower inrush current and speed vs non inverter. Also, thanks to the inverter compressor, your system will realize huge energy savings. The higher purchase cost will be compensated by the reduction of electricity cost.To prevent your air conditioner from major failure, it is crucial to periodically maintain your AC as per manufacturer recommendations.Can we install inverter units near to sea? Does salty environment affect the inverter components?Daikin I nverter air conditioners are equipped with anti-corrosion protection as standard.All Daikin standard equipment, regardless of technology, are equipped with anti-corrosion protection.In very harsh environment, regardless of the technology, if the outdoor location is less than 500m from the sea shore and the unit is facing direct wind, Daikin requires purchasing additional heavy anti-corrosion protection option. The type of treatment will depend on the environment. For more details, please contact a Daikin representative.What about the lifetime of Inverter compressor?Longer lifetime for Inverter!The variable speed operation of inverter allows extension of compressor lifetime compared to non-inverter equipment. Non inverter system must repeatedly turn ON and OFF its compressor,resulting in a higher stress on the motor.Do you have any questions?
