In cold regions, a common question is, at what temperature do air source heat pumps fail? In short, it depends on the system design, the refrigerant used, and the control logic. But with current technology, most high-quality air source heat pumps remain effective at temperatures well below freezing.
Traditionally, standard air source heat pumps have difficulty operating efficiently below -5°C to -10°C. In this case, their coefficient of performance (COP) drops sharply and a backup heat source may be required. However, modern systems designed for low-temperature air source heat pumps can work properly even at temperatures of -20°C or lower.
Take Leomon's RS series, for example, which uses intelligent frequency control, cold climate adjustment, and adaptive defrost technology to operate effectively at temperatures as low as -25°C. At this temperature, the heat pump can still maintain a stable indoor temperature and high SCOP performance. The secret lies in the following points:
1. Inverter compressor technology, real-time output adjustment
2. Optimized refrigerants (such as R410A and CO2) for sub-zero heat exchange
3. Dual temperature sensors and active defrost algorithm
4. Microchannel heat exchanger for enhanced low-temperature heat absorption
Many people do not realize that in cold climates, air source heat pumps will only fail if they are not matched to the local climate or the installation size is not appropriate. In most parts of Europe and North America, the minimum winter temperature is usually between -5°C and -20°C, and systems like the BLN CO2 series or R290 environmentally friendly heat pumps can provide efficient and uninterrupted heating.
So, at what temperature will air source heat pumps fail?
In fact, below -30°C, most air source units need a backup heat source. But in 99% of residential and commercial use scenarios, especially in Europe, the right air source heat pump will perform well throughout the winter.
