12kW 380V 3 Phase R410A Split DC Inverter Air Source Heat Pump
12kW air source heat pump
,380V 3 phase heat pump
,R410A DC inverter heat pump
Engineered to deliver powerful 12kW thermal output in sub-zero winter climates, this split-type air-to-water heat pump isolates all hydronic components inside the building to prevent freezing. Driven by a high-efficiency Panasonic DC inverter compressor operating on 380V/3Ph power, it modulates operating frequency dynamically to ensure reliable heating performance with ultra-low vibration and operating noise.
Designed for compact installation, the RFJ-AW-12DS features an integrated circulating water pump and a built-in 3kW auxiliary electric heater directly inside the indoor hydronic unit. The auxiliary heater provides automatic supplemental thermal capacity during extreme cold snaps, while concealed shut-off valves maintain a clean aesthetic footprint.
Equipped with an electronic expansion valve (EEV) regulated by intelligent PID control algorithms, the system precisely adjusts refrigerant flow to adapt to changing ambient temperatures and heating loads. This dynamic matching minimizes supply water temperature fluctuations, improves seasonal energy efficiency, and lowers operating costs.
- Panasonic DC inverter compressor
- High-efficiency plate heat exchanger
- Built-in circulating water pump
- Built-in 3kW auxiliary electric heater
- Concealed stop valves
- Electronic expansion valve
- Intelligent controller with WiFi
- Split-Type Protection: Indoor positioning of the plate exchanger and water loop prevents outdoor freezing hazards; connecting refrigerant piping between units is excluded.
- 380V Three-Phase Power: Powered by 380V/3Ph/50Hz supply to ensure balanced electrical phase loading across commercial and large residential installations.
- Cold-Region Residential & Light Commercial Heating: Ideal for large villas, detached residences, and light commercial buildings using underfloor heating grids, low-temperature hydronic radiators, or fan coil units in cold climates.
- All-in-One Space Heating & Domestic Hot Water: Provides high-temperature water for space heating and domestic hot water generation, ensuring reliable warmth throughout winter.
- Clean Energy Boiler Retrofits: Replaces fossil-fuel or direct electric boiler systems, reducing household energy consumption and greenhouse gas emissions.
