To reduce carbon emissions to the environment and curb global warming, an R290 Full DC Inverter Heat Pump has been developed. Compared to R410A refrigerant with a GWP of 2100 and R32 with a GWP of 675, R290 has a GWP of less than 20 and is recognized by the industry as the most eco-friendly refrigerant with significant development potential.
The R290 FULL DC INVERTER Heat Pump meets diverse needs throughout the year, including house heating, cooling, and domestic hot water (via 3-way valve):
Under low ambient temperatures, normal heat pump performance is often limited. Our R290 FULL DC INVERTER heat pump operates stably and efficiently in extreme cold regions down to -25ºC without EVI technology, maintaining high COP and outputting 75ºC hot water.
Full DC inverter technology allows the unit to intelligently adjust operating frequency and control water temperature. It can save up to 50% energy compared to ON-OFF units and up to 75% compared to traditional electric heat pumps.
Key Components: DC Inverter Panasonic Compressor, Stepless DC Inverter Fan Motor, DC Inverter Water Circulation Pump.
Equipped with three-layer sound insulation and noise reduction technology, the unit runs smoothly and quietly. The integrated IoT cloud platform allows for remote monitoring of data via Wi-Fi, facilitating quick technical support and reducing maintenance costs.
