LOW GWP R290 REFRIGERANT
To reduce carbon emissions to the environment and curb global warming, Power World has developed an R290 Full DC Inverter Heat Pump. 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 development potential and eco-friendly refrigerant.
Feature：
1. Multifunctional heat pump
The perfect performance of the R290 FULL DC INVERTER Heat Pump can meet the user's needs of house heating, cooling, and domestic hot water throughout the year ( by a 3-way valve):
• Heating Only
• Cooling Only
• Domestic Hot Water Only
• Heating+ DHW (Priority)
• Cooling+ DHW (Priority)
2. Reliable operation in extreme temperatures of -25°C.
3. Powerful heating can output 75°C hot water.
4. The noise is lower than 47 dB.
5. SCOP can be as high as 4.86
6. FULL INVERTER TECHNOLOGY
