Malfunction Forecasting
Thanks to the Al cloud server, malfunction can be forecasted when system running parameter is abnormal.
-
Technician can be sent to site to check the system before it stops.
Refrigerant Cooling DesignWe use refrigerant to cool down inverter modular board tokeep it in a safe condition even when outdoor temperature isupto55°C
Wide Outdoor Operation Range1. Due to EVI technology, CHV PRO heating performanceincreased by 35% compare to conventional VRF system.2. Due to EVI technology, CHV PRO still has 85% of ratedcapacity even in -15°C.
Power Saving Mode
According to power usage, realize 7-level power limit setting.
Refrigerant Status Detection
1. Built-in with smart refrigerant auto check function, which can give suggestion about refrigerant status.
2. Different code means different refrigerant status:
High Efficiency DC Inverter Compressor
1. From Hitachi, famous inverter compressor manufacturer.
2. R410a ECO friendly refrigerant.
3. Small torque fluctuation, low vibration and quiet operation.
4. High efficiency due to its patent internal structure design.
5. Internal oil circulation structure.
High Efficiency DC Motor
1. High efficiency DC fan motor is from well-known brand.
2. Low noise and high efficiency because of high-density wire winding engineering.
3. Brushless with built-in sensor.
Stepless Control
DC fan motor can be stepless contolled by outdoor PCB according to system's operating pressure. And it is able to reducethe energy consumption and maintain the system in the best performance.
180° Sine Waveform Control
The perfect combination of 180° Sine waveform rotor frequency drive control technology and excellent IPM inverters, reduces the reactive loss of motor-driven, increases motor efficiency by 12%.
2-in-1 Refrigerant Flow Path Design
Supercooling Flow Path Design
Supercooling flow path design, separates the refrigerant inlet and outlet, increase the supercooling degree, reduce the effect of high temperature inlet gas refrigerant to low temperature outlet liquid refrigerant, therefore,the system efficiency will be greatly increased.
Wide Operation Range
VRF has a wide ambient temperature operation range, cooling at -5-55℃, and heating at -30-30℃
Snow-proof Function
In the cold weather, outdoor fan will start to run for a while at intervals to prevent the snow to accumulate on fan blade, because accumulated snow will freeze and block fan blade rotating, even worse it will damage the motor.
Module back up function.
When some modules are failure, the others can keep running by simply settings.
Compressor back up function
When one compressor is failure, the other one can keep running by simply settings.
Fan motor back up function.
When one fan motor is failure, the other one can keep running by simply settings.
All Outdoor Units Cycle Operation
1. In one combination system, any outdoor unit can run as master unit.
2. Cycle operation equalizes the running time of the outdoor units, greatly extending the lifespan of outdoor units in one system.
IDU and ODU Positioning Function
Turn on the positioning function through the controller, and all the IDU and ODU of the same system will beep through the built-in buzzer, which is convenient for quick positioning during system commissioning, troubleshooting and after sales maintenance.
Intelligent Defrosting Program
5 special defrosting mechanisms
The dedicated temperature sensor monitors the temperature of the condenser coil of the outdoor unit in real time, intelligently selects the defrost mechanism and judges the timing of defrost, effectively prolongs the normal heating time, improves comfort, and achieves energy-saving effects.
Outstanding Comfort Ability
1. VRF system have excellent cooling&heating performance, thanks to the high efficiency DC fan motor, DC compressor and optimized refrigerant flow control logic.
2. Precisely room temperature control by adopting 2000 pulse EXV. Indoor temperature fluctuation can be maintain within 0.5℃, offers outstanding comfort ability
Environment Friendly
Refrigerant R410A(HFC),low carbon footprint, no harm to Ozone.
Silent Mode, Night Time Noise Control
1. Compressor and fan motor rotating speed can be reduced to lower the noise at night.
2. Maximum 10dB(A) decrease.
Remote ON/OFF Control Function
1. Indoor units standard build in with ON/OFF control port.
2. It can be used for hotel card control and also can be used for long distance remote ON/OFF control. And no need additional hotel VRF indoor unit control module.
3. When contactor is open(card pulled out), indoor unit will be off can not be controlled, current running parameters will be saved in indoor PCB.
4. When contactor is close(card insert), indoor unit will recover previous running state.
