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.
The R290 FULL DC INVERTER Heat Pump meets house heating, cooling, and domestic hot water needs throughout the year via a 3-way valve:
Under low ambient temperatures, performance is often limited. This R290 FULL DC INVERTER heat pump operates stably 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 control water temperature. It can save up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boiler electric heat pumps. Components include a DC Inverter Compressor, Stepless Fan Motor, and Water Circulation Pump.
Passed the ERP A+++ energy class test. The SCOP can be as high as 4.86, ensuring ultra-high energy efficiency at both 35°C and 55°C water temperatures.
The IoT cloud platform allows remote monitoring via Wi-Fi or DUT. It records all operating parameters. If an error occurs, reports are synchronized to the background for quick solutions, saving after-sales costs.
