7KW DC Inverter Ground Source Heat Pump
Brand:RFJ
Model:RFJ-WW-7DC
Heating capacity:7KW
Refrigerant:R32
Voltage:220V/1/50Hz
OEM/ODM:Support
Description
Mitsubishi DC Inverter Rotary Compression Technology
Powered by a premium Mitsubishi DC inverter rotary compressor, the RFJ-WW-7DC ground source heat pump dynamically modulates motor speed to match real-time space heating demand. This stepless inverter technology eliminates energy-wasting on/off cycles, maintaining ultra-stable water temperatures while cutting seasonal electricity consumption by up to 60% compared to conventional fixed-speed heating systems.
4.3-Inch Color Touchscreen with Smart WiFi Control
Designed for modern smart-home integration, the unit comes equipped with an intuitive 4.3-inch color touchscreen controller featuring built-in WiFi connectivity. Users and facility managers can remotely adjust target supply temperatures, set operating schedules, monitor system parameters, and receive real-time operational alerts directly through a mobile smartphone application.
High-Efficiency R32 Plate Heat Exchanger & Flow Safeguards
Utilizing eco-friendly R32 refrigerant, the RFJ-WW-7DC delivers high thermodynamic efficiency and a low Global Warming Potential (GWP). Its compact brazed plate heat exchanger maximizes thermal energy recovery from constant 4°C–12°C subsoil temperatures, while an integrated water flow control module protects the circuit against freeze-up or low-flow conditions. Designed without an internal water pump, the system provides installers total freedom to select external pumps tailored to site hydraulics.
Applications
