15KW Geothermal Heat Pump For Home Use
Brand:RFJ
Model:RFJ-WW-15X
Heating capacity:15KW
Refrigerant:R32/R410
Voltage:220V/1/50Hz
OEM/ODM:Support
Description
High-Efficiency GMCC Rotary Compression
The RFJ-WW-15X geothermal heat pump is built around a heavy-duty GMCC rotary compressor, delivering continuous 15 kW thermal output for residential and light commercial heating. By utilizing stable year-round subsoil energy (4°C to 12°C), the system achieves superior seasonal heating efficiency (COP), reducing reliance on traditional electrical heating elements and lowering annual energy bills by up to 60%.
52B-46 High-Performance Dual Plate Heat Exchangers
Fitted with model 52B-46 dual-side brazed plate heat exchangers, the unit optimizes refrigerant-to-water heat exchange efficiency across both the ground collector side and the hydronic distribution side. The high-turbulence plate design enhances heat transfer rates while keeping internal liquid volume low, enabling rapid heating reaction times and compact overall equipment dimensions.
Integrated Flow Protection & Flexible Hydronic Sizing
To prevent operation under low-flow or dry conditions, the RFJ-WW-15X includes a factory-installed internal water flow switch. Designed without an internal water circulation pump, this unit allows HVAC contractors complete freedom to select and size external primary/secondary pump stations tailored to the precise hydraulic head and flow resistance of the ground loop array.
Applications
Multi-Story Residences
Delivers constant hydronic radiant floor heating and domestic hot water for larger single-family homes and estates.
Commercial Eco-Resorts
Serves small hospitality installations requiring quiet, continuous space heating with minimal operational carbon footprint.
Greenhouse Installations
Provides low-cost baseline heating for commercial greenhouses, aquaculture ponds, and temperature-sensitive storage spaces.
