Low ambient temperature heat pumps are innovative solutions for efficient heating in colder climates. These systems are specifically designed to perform well in extreme cold weather conditions, while operating in an energy-efficient and environmentally friendly manner.
Why are low temperature heat pumps important?
Previously, the efficiency of traditional heat pumps decreased significantly as the outside temperature dropped, especially below -5 °C. Therefore, they were only economical and efficient in areas with milder climates. However, the new generation of low ambient temperature heat pumps can now operate stably and with high efficiency even at outside temperatures of -25 °C.
How do they work?
Special refrigerants : Low ambient temperature heat pumps use modern refrigerants (e.g. R32 or R410A ) that provide more efficient heat exchange even in extremely cold conditions.
Advanced compressor technology: These systems use high-performance, two-stage or inverter compressors that increase the efficiency and performance of the heat pump even at low temperatures.
Inverter technology adapts to temperature changes, consuming less energy while ensuring optimal operation.
No additional heating: While traditional heat pumps often required additional electric heating in cold weather, low ambient temperature models generally avoid this, making them more economical.
What are the benefits?
Energy efficiency even in cold weather: These heat pumps are able to achieve a high COP (coefficient of performance) even at low temperatures, which means they consume less energy to produce the same amount of heat.
Applicability in extreme climates: Such systems are ideal for those who live in regions with cold winters and want to reduce their heating costs.
Environmentally friendly operation: Low-temperature heat pumps reduce fossil fuel consumption, resulting in lower carbon dioxide emissions, which contributes to sustainable development.
Flexible installation options: Can be used in new construction and renovation of older heating systems. Can be combined with underfloor heating, radiators or fan-coil systems .
What should we pay attention to when selecting them?
Minimum operating temperature: We check whether the given heat pump can operate stably at the lowest temperature typical in the region.
SCOP value: The SCOP (Seasonal Coefficient of Performance) value shows how efficient the heat pump is over the entire heating season. A higher SCOP means better energy efficiency.
Capacity sizing: It is important that the heat pump capacity matches the building's heat demand. A heat pump that is too small or too large can reduce efficiency and increase costs.
Summary
Low ambient temperature heat pumps represent the pinnacle of modern heating technology, especially in colder climates. Thanks to their innovative design and advanced technology, they provide stable and economical heating even in extremely cold conditions. These systems not only reduce heating costs, but also contribute to sustainable and environmentally friendly energy use.
