The Daikin Difference for Engineers & Architects

Since mini splits have no ducts, they avoid the energy losses associated with ductwork used by forced air systems. Per ASHRAE’s “Top Ten Things About Air Conditioning – Ducts Matter A Lot”, “Duct leakage can zap 20 to 40% of the energy out of even a well-operating air conditioner.” Additionally, ductless mini splits come with a remote control that has been designed, tested, and proven to operate the unit instead of forced air systems wired in the field with another brand of thermostat. Operating each indoor unit separately with a remote offers superior zoning and energy savings. Un-zoned forced air systems typically heat and cool several rooms or even an entire home with one thermostat in one room.

The largest inefficiencies of forced air heating and cooling systems come from the simple fact that they are assembled on-site with various brands and many different parts and pieces that have never been assembled in the same way before and, therefore, never tested to perform as specified. The performance of forced air systems is, therefore, highly dependent on the varying skill level of the installer and the quality of their work. Most homeowners and homebuilders are unaware that it is common for HVAC installers to use a 3rd party evaporator coil – evaporator coils that are not manufactured by the same company as the outdoor unit or indoor air handling unit.  The evaporator coil is a key component within the HVAC system. Systems that are “matched” have all the main components produced by the same manufacturer and have the same brand name.  A matched system is superior as it has been “tested” as a “matched system” to meet the efficiency (SEER) performance specified.  Due to installation inconsistency and related performance issues, home performance testing is becoming more common as the government and consumers continue to seek higher efficiencies. 

Conversely, a ductless split system is a factory-engineered solution. All key components required to assemble the system are provided, with the installer only needing to obtain piping, insulation, and wiring/breaker components. The final assembled system will meet the specified system performance and is less dependent on the installer’s skill level, though trained installer personnel are always required.

There is no need to perform any home performance testing as there is no opportunity for leaky ductwork or energy inefficiency of any sort.

Select Daikin systems offer high heating capacity at low temperatures, down to -4°F, without turning to alternative heat sources.

Heat pumps are around 300% efficient. This means that for every unit of energy used by the heat pump in operation, three or more heat units are generated for use in a building.
As heat pumps work by extracting available heat from the outside air, they are far more efficient than even the most efficient fossil-fuel-based heating systems. Heat pumps featuring Daikin’s inverter technology are particularly efficient for indoor heating.

Using an integrated heat pump solution to both cool and heat a building can also mean a lower initial investment and simpler operation and maintenance procedures.

Individual temperature control provides comfort for the entire space. Each system is equipped with a wireless remote control, providing the ability to change the settings anywhere in the comfort of the conditioned space. A large display provides an overview of the unit's operation, and user-friendly buttons offer advanced capabilities from temperature control to energy-saving features.

Daikin systems operate at the required capacity, delivering the exact amount of cooling or heating to maintain the desired comfort.

• Start-up time and energy consumption are reduced by one-third (compared to normal on/off units).
• Avoids cycling operation of the compressor, reducing costly current (amp) peaks.
• Minimizes space temperature fluctuations.

The Right Solution…from Start to Finish

A major advantage of selecting a Daikin system is having Daikin as your service partner. The Split and VRV-S systems are delivered 80% complete, virtually eliminating the installation, commissioning and service problems that can arise with a conventional air-conditioning system. If issues occur, the systems have built-in self-diagnostics that accurately identify trouble spots for quick repairs.

Daikin systems also come with one of the best warranties in the industry. Best of all, most of the major components and refrigerant, down to the controllers, are made by Daikin – contractors never have to worry about getting the runaround. One supplier. One phone call.

Daikin systems are designed for reliability and durability. The standard warranty provides a solid level of protection, and our Warranty Plus program offers additional protection – one of the best warranty programs in the ductless industry.

• Optional extended labor warranties are available for 5 and 10 years.
• Optional extended parts warranties are available for 5 and 10 years, depending on the product.
• Please refer to warranty documents for full warranty conditions.

Our product focus is always on performance and quality. Some examples:

PE Fin Coil  
Our PE fin coil coating protects the outdoor unit coil from corrosion and reduces friction to allow water to drain quickly from the coil during defrost.

Daikin-Designed Compressors  
Unlike many other air conditioning manufacturers, Daikin manufactures our compressors from our factories worldwide. This is important because the compressor is the very heart of the air conditioning system.

Daikin has always been at the forefront of developing compressor technology and now offers a comprehensive range of swing, scroll and single-screw compressors. Inverter compressor control is applied throughout our product range, delivering enhanced comfort and system efficiency. Daikin-designed compressors are optimized to work reliably and efficiently under all load conditions.

• Reverse design-to-cool windings with discharge gas instead of suction provide more constant temperature and reduce thermal shock to windings of the constantly changing suction gas.
• More reliable High thrust oil to reduce friction, which increases reliability, and improves performance.
  

All manufacturing bases in the Daikin Group have obtained the globally recognized ISO 9001 (quality management system), and ISO 14001 for environmental performance certification. We also provide customers with the information they need to use our products safely. Company divisions maintain high levels of product quality and ensure proper management of each department, such as development, materials and parts procurement, and production.

Our responsibility goes beyond simply satisfying customers; we believe that we also have a duty to society to offer products and services that are safe, high quality, and environmentally conscious.

Equipped with the adaptive inverter drive system, the compressor varies its speed (instead of just turning on and off) to closely match the heating or cooling demand, reducing energy consumption and maximizing savings.

Designed with Daikin's swing type compressor, integrated parts reduce friction, resulting in smoother and quieter rotation and increasing performance and longevity. Systems are backed by the best warranty in the business.

Special anti-corrosion treatment on the outdoor unit heat exchanger increases resistance to salt damage and atmospheric corrosion, ensuring greater durability.

Long piping runs increase flexibility. All RA units come pre-charged with enough refrigerant to supply 33 ft of piping, minimizing commissioning time and cost.
