Description
380V Three-Phase Mitsubishi DC Inverter Drive
Driven by a high-efficiency Mitsubishi DC inverter rotary compressor, the RFJ-WW-12DC ground source heat pump delivers a nominal 12 kW thermal output for residential and light commercial projects. Running on a balanced 380V / 3Ph / 50Hz power supply, the variable-speed drive continuously modulates compressor rpm to match real-time building heat demands.
4.3-Inch Color Touchscreen with Smart WiFi Connectivity
Equipped with an intuitive 4.3-inch color touchscreen interface, the system gives users complete visual control over supply/return water setpoints, compressor operating frequencies, and system diagnostics. Integrated WiFi smart control, allowing homeowners and facility engineers to adjust temperature schedules, monitor energy usage, and receive real-time operational alerts from anywhere.
System Flow Safeguards
A high-efficiency brazed plate heat exchanger maximizes thermal recovery from constant 4°C–12°C subsoil energy sources. Built with an internal water flow control module, the unit protects against low-flow or freeze-up conditions while omitting an internal water pump to give installers full freedom to size external circulation pumps to site hydraulics.
Applications
Large Residential Estates
Provides efficient 12 kW hydronic underfloor radiant heating and central domestic hot water for homes ranging from 120 m² to 180 m².
Commercial Office Suites
Delivers low-noise, consistent space heating for commercial office floors, boutique retail shops, and medical centers.
Geothermal Ground Source Arrays
Connects seamlessly with deep vertical rock boreholes, horizontal soil loop fields, groundwater doublet wells, and lake water loops.
