Variable Refrigerant Flow

Brand: Gree

Variable refrigerant flow system work for both cooling and heating for all applications. VRF system is available to connect more indoor unit with different model and capacities. Temperature controlled by individual, centralized or automation as BMS for higher efficiency and more energy saving. VRF system give independent and individual control possibility. Building can design zon by zone depends on architectural requirements. The system can record the highest outdoor temperature. At night, the system will automatically turn to quiet mode. Maintenance is easy and operation cost is lower than other system. System operate user friendly. All DC Inverter Technology to Improve Compression Efficiency.VRF system make accurate control (+-0,5C ) in order to realize high comfort. VRF system desing as flexible and has long distance piping advantages for high rise buildings. With compact design, the outdoor unit can be carried to the roof of building through elevator, with no need of crane. It is easier for delivery and installation. Non-polar CAN Technology to improve communication efficiency. Sensorless control technology guarantees lower noise, less vibration and steadier operation. Wider range of voltage and operation condition. Intelligent defrosting control. Sub-cooling control technology to ensure optimal cooling and heating.
