Driven by a high-efficiency Mitsubishi DC inverter rotary compressor, the RFJ-WW-7DC dynamically adjusts output capacity to match real-time indoor thermal demand. This variable capacity regulation maintains stable room temperatures while eliminating energy waste from frequent start-stop cycles.
Features an intuitive 4.3-inch color screen controller paired with built-in WiFi connectivity for intelligent system management. Homeowners and property managers can monitor operational parameters, adjust temperature setpoints, and switch heating modes remotely via mobile app.
By tapping into constant underground thermal energy maintained between 4°C and 12°C year-round, this DC inverter heat pump cuts heating energy consumption by up to 60% and significantly reduces CO2 emissions compared to electric or gas boilers. Engineered with acoustically insulated housing, it operates at low noise levels for high indoor comfort.
Mitsubishi DC inverter rotary compressor, high-efficiency plate heat exchanger, 4.3-inch color screen controller, built-in WiFi module, and water flow control module.
