Biagio Lamanna, CAREL’s Head of the HVAC/R Knowledge Center, addresses various questions about heat pumps in his latest blog. He focuses on the efficiency of this technology, aligning with the first-ever Heat Pump Day (October 21), launched by the European Heat Pump Association (EHPA).
Here are the questions that he answers in detail:
1. How can the real efficiency of a heat pump be calculated at low outdoor temperatures, such as -20°C?
2. At what temperatures is there a significant decline in heat pump COP in heating mode?
3. What is the COP of a high temperature R-290 residential heat pump?
4. What is the efficiency of monobloc R-290 heat pumps at -20°C outside temperature working with a water-glycol mixture?
5. Which refrigerant pipes should be thermally insulated in a heat pump?
