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 the highest development potential.
The perfect performance of the R290 FULL DC INVERTER Heat Pump meets the user's needs for house heating, cooling, and domestic hot water throughout the year (managed by a 3-way valve):
Under low ambient temperatures, the performance of normal heat pumps is often limited. Our R290 FULL DC INVERTER heat pump operates stably and efficiently in extremely cold regions down to -25ºC without EVI technology, maintaining a high COP and outputting 75ºC hot water.
Full DC inverter technology allows the unit to intelligently adjust operating frequency and control water temperature to keep rooms at a constant temperature. It can save up to 50% energy compared to ON-OFF units and up to 75% energy compared to traditional electric heat pumps.
Core Components: DC Inverter Panasonic Compressor, Stepless DC Inverter Fan Motor, DC Inverter Water Circulation Pump.
The IoT cloud management platform connects via Wi-Fi or DUT for remote monitoring. It records all operating parameters. If an error occurs, reports are synchronized to the service provider background to provide quick solutions, saving after-sales communication and time costs.
