GREE 10HP DC Inverter Cooling & Heating Floor Standing Type Split Air Conditioner Model RF28WPd/Na-M | 1 Year Full 5 Year Compressor Warranty

(1) High Efficiency

GREE 10HP Split Air Conditioner RF28WPd/Na-M

1. Firstly ; The system adopts DC motor, which greatly improved efficiency.
2. Secondly; High-efficient magnetic reluctance inverter compressor:
3. Thirdly; High-efficient magnetic reluctance compressor is adopted to take advantage of the magnetic reluctance torque of compressor.
4. Under the same output capacity,the efficiency can be improved by 5%.
5. Advanced torque control technology: minimum current and maximum torque control technology adopts 
6. the most optimized control principle to realize maximum torque output with minimum current and
7. reduce loss of motor winding and intelligent power module for higher energy efficiency.
8. Closed-loop start-up technology of compressor: Self-innovative closed-loop start-up control is applied to enable output torque follow with load torque,
9. whose start-up current is small and start-up is more reliable.180° sine wave DC variable speed technology: 180º current output waveform is smooth sine wave with small harmonic wave content
10. , small torque pulsation, wide adjustable range and stable operation of motor, 
11. which can satisfy the temperature requirement in various occasion, save electricity greatly and ensure user’s comfort in maximum

.

(2) Latest CAN Bus Communication

GREE 10HP Split Air Conditioner RF28WPd/Na-M

1. Furthermore; The latest communication way-CAN bus communication is adopted,
2. Moreover; which greatly improves ant interference ability,
3. Additionally; precisely controls the indoor unit and improves the reliability of system.Conventional Communication wire can be used to increase the flexibility of project installation.
4. Widely apply to public places such as shopping mall, restaurant,
5. ball room, meeting room, supermarket,
6. etc., creating a comfortable and pleasant environment for you.
7. This series unit adopts side air discharge design,
8. with compact size, decreasing installation environment
9. limit greatly.Features for the complete unit system are as below:

(3) Long Connection Pipe and Big Height Difference

1. Firstly; The connection pipe between indoor unit and outdoor unit can be as long as 70m.
2. Secondly; Project installation
3. condition is wider while the limitation of installation distance is smaller.
4. Lastly; The max allowable height difference
5. between indoor unit and outdoor unit is 30m.

(4) Wide Operation Range

1. The system can operate constantly and reliably in a wide temperature range(cooling: -7~52°C, heating:
2. -15~24°C), which is not affected by atrocious environment.

(5) PID Intelligent Capacity Adjustment

1. The system applies the original technology of PID intelligent capacity adjustment, which quickly and
2. precisely controls indoor ambient temperature according to set temperature, with small temperature fluctuation
3. and great comfort.

(6) Convenient For Installation

1. Also; The size of side discharge casing is smaller and the weight is lighter, which saves space greatly, the floor
2. Moreover; space will decrease 30% and loading quantity will increase 20%;
3. Besides All;Flexible transportation, move in/out the passenger elevator directly; convenient for installation, and it can
4. be installed in wall.
