To reduce carbon emissions to the environment and curb global warming, the R290 Full DC Inverter Heat Pump has been developed. Compared to R410A refrigerant (GWP 2100) and R32 (GWP 675), R290 has a GWP of less than 20 and is recognized by the industry as the most eco-friendly refrigerant.
The perfect performance of the R290 FULL DC INVERTER Heat Pump can meet house heating, cooling and domestic hot water needs throughout the year (via 3-way valve):
Under low ambient temperatures, normal heat pumps face limited performance. This R290 FULL DC INVERTER heat pump can operate stably and efficiently in extremely cold regions of -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 water temperature. It saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers.
Core Components: DC Inverter Compressor, Stepless DC Inverter Fan Motor, DC Inverter Water Circulation Pump.
The unit has passed the ERP A+++ energy class test. Efficiency reaches A+++ at both 35°C and 55°C water temperatures. The SCOP can reach as high as 4.86, ensuring ultra-high energy efficiency.
The IoT cloud management platform connects via Wi-Fi or DUT for remote monitoring. If an error occurs, reports are synchronized to the service provider for rapid solutions, saving time and maintenance costs.
