The DC Inverter VRF (Variable Refrigerant Flow) System is an advanced air-conditioning solution designed for commercial buildings, hotels, hospitals, offices, and large residential projects. It uses full DC inverter technology with intelligent capacity control to deliver precise cooling and heating, high energy efficiency, low operating noise, and reliable performance even under extreme ambient conditions. This system supports multiple indoor units connected to a single outdoor unit, allowing flexible design, long piping distances, and independent zone control. The catalogue highlights the use of enhanced vapor injection compressor technology, DC inverter compressor & fan motors, advanced oil management, intelligent defrosting, and R410A refrigerant, making the system suitable for both comfort and energy-saving applications.
