WIDE OPERATION TEMPERATURE RANGE

The versatile operation range of the VRV Apt system works to reduce limitations on installation locations. The operation temperature range for heating goes all the way down to -20C, while cooling can be performed with outdoor temperatures as high as 54C. Both these achievements are due to the adoption of a high-pressure dome-type compressor which is specially designed for operation in extreme ambient conditions.

IMPROVED RELIABILITY AT HIGH AMBIENT TEMPERATURES

Refrigerant cooling technology ensures the stability of PCB temperature & improves reliability at high ambient temperatures. It is possible to cool the inverter power module stability even at high ambient temperature. This helps to keep air-conditioning capacity and also ensures efficient and reliable operation. In addition to stable cooling, Refrigerant Cooling Circuit prevents PCB board from dust, water, and small animal entering, making this design solution ideal for hot desert climate compared to traditional air-cooled PCB Boards.

Additional Coating is applied to PCB for strengthening to cope with high ambient environment & to ensure longer life of PCB.Wide Area Heat Exchanger is designed to ensure delivery of required capacity at high ambient conditions. Heat Exchanger Fins are covered with Blue Film which consists of corrosion resistance layer covered with hydrophilic surface treatment coating to withstand harsh environment conditions.

SWING COMPRESSOR

Thanks to its smooth rotation, the swing compressor decreases friction and vibration. It also prevents leakage of refrigerant gas during compression. These advantages provide quiet and efficient operation.

HIGH COP DURING BOTH COOLING AND HEATING OPERATIONS

One of the top features of VRV Apt is its energy efficiency. It achieves high COP during cooling and heating operations especially at part load.

COMPRESSOR EQUIPPED WITH RELUCTANCE DC MOTOR

VRV Apt Outdoor Units are equipped with the Reluctance DC motor for the compressor. The Reluctance DC motor uses 2 different types of torque, neodymium magnet*1 and reluctance torque*2. This motor can save energy because it generates more power with a smaller electric power than an AC or conventional DC motor.

*1 A neodymium magnet is approximately 10 times stronger than a standard ferrite magnet.

*2 The torque created by the change in power between the iron and magnet parts.

Note: Data are based on studies conducted under controlled conditions at a Daikin laboratory using Daikin products.

SMOOTH AIR INLET BELL MOUTH AND AERO SPIRAL FAN

Guides are added to the bell mouth intake to reduce turbulence in the airflow generated by fan suction. The Aero Spiral Fan features fan blades with bent blade edges, further reducing turbulence.

NIGHT-TIME QUIET OPERATION FUNCTION

Operation sound level selectablefrom 3 steps for the night mode.

 

MODE 1 AUTOMATIC MODE

Set on the outdoor PCB. The time of maximum temperature is memorized. The low operating mode will become active 8 hours*1 after the peak temperature in the daytime, and operation will return to normal 10 hours*2 after that. The operation sound level for the night mode can be selected from 47 dB(A) (Step 1), 44 dB(A) (Step 2), and 41 dB(A) (Step 3).

MODE 2 MANUAL MODE

Starting time and ending time can be input. (An external control adaptor for outdoor unit, DTA104A61 or DTA104A62, and a locally obtained timer are necessary).

MODE 3 COMBINED MODE

Combinations of modes 1 and 2 can be used depending on your needs.

*1. Initial setting. Can be selected from 6, 8 and 10 hours.

*2. Initial setting. Can be selected from 8, 9 and 10 hours.

Note:

• This function is available in setting at site.

• The relationship of outdoor temperature (load) and time shown in the graph is just an example.

*The capacity reduction rate differs depending on the operation sound level step selected.

Currently, the energy efficiency of cooling devices is measured in artificial and standardized conditions. For air conditioners, this is done at a constant temperature of 46 °C or 35 °C and at full cooling capacity. This results in T1 & T3 energy efficiency (EER), which is representing only two points to conclude on Energy performance.

In other markets, like in the US and Europe, seasonal performance is measured with IPLV, SEER or ESEER calculations based on real-life conditions. However, these calculation methods have not been adopted for high Ambient or hot climates. In order to correct this situation, a more realistic calculation method called Cooling Seasonal Performance Factor for Hot Climate CSPFT3 has been developed by the ISO Refrigeration and Air-Conditioning Subcommittee (SC6) for the testing and rating of air conditioners and heat pumps. This is the standard ISO 16358 -1 Amendment 1 issued in 2019 for the hot T3 climate zones.

The implementation of the Seasonal Efficiency calculation reflects a more realistic energy efficiency value through the entire cooling season at hot climate conditions compared to the currently used EER value.

Application

centralised_AC-removebg-preview.png

In a conventional split air-conditioning system, a house requires samenumber of outdoor units and indoor units. For example, a place withfour rooms will have four indoor units and four outdoor units.

An apartment or a house that does not have sufficient space will find difficult to accommodate numerous outdoor units. Even if the outdoor units are somehow crowded together they will consume a lot of space, look cluttered and ruin the aesthetics of the house.VRV Apt replaces all the outdoor units of the house with just one outdoor unit. A total of 9 indoor units can be connected to one outdoor unit to create the space you have always desired. Also you have different styles of indoor units like duct type and wall mounted type that can be connected with a single outdoor unit. Furthermore, actual piping length of up to120 meters coverage of widespread spaces is ensured.

The trunk-shaped outdoor unit can easily be installed on a balcony, realizing complete system installation within each floor. The compact outdoor unit can be hanged on the wall eliminating the need for floor space, which enables more useful utilisation of the space on the building rooftop. To hide outdoor units with the fence of the balcony or the outer wall of the Roof, the outdoor unit's height needs to be 1m or lower. VRV Apt has significant reduction in height (870mm only) thanks to 1 fan design. Now, the height including the frame for installation has been realized to be 1 m or lower, enabling installation of outdoor units without damaging scenery.
