Q: What is SCOP and how is it different from COP?
A: COP is the instantaneous efficiency under a single working condition. SCOP stands for Seasonal Coefficient of Performance, the annual average heating efficiency, which is the key index for EU ErP certification and heat pump selection.
Q: What is the difference between air-source heat pump and ground-source heat pump?
A: Air-source heat pumps extract heat from ambient air, lower upfront cost and easier installation. Ground-source heat pumps use stable underground heat, higher efficiency but require land for boreholes or ground loops.
Q: Heat pump vs air conditioner: what are main differences?
A: Air conditioners mainly focus on cooling. Heat pumps are designed for year-round heating, can supply stable low-temperature heating and domestic hot water, and adopt water circulation system for space heating.
Q: What is GWP? Why choose low-GWP refrigerant like R290?
A: GWP means Global Warming Potential. R290 has an ultra-low GWP of 3. It complies with EU F-Gas regulations and upcoming refrigerant restrictions, with high heat transfer efficiency.
Q: Are your R290 heat pumps CE / ErP certified for EU market?
A: Yes. Our heat pumps carry CE, ErP, TUV and other required certifications, fully meeting EU market access requirements.
Q: What is the difference between R290, R32 and R410A refrigerants for heat pumps?
A: R290: low GWP, natural refrigerant, flammable and requires safety design. R32: moderate GWP, widely used, mildly flammable. R410A: high GWP, being phased out under F-Gas rules.
