Low Temperature Heat Pump for Cold Climates | High Efficiency

Low temperature heat pumps are specifically engineered to operate efficiently in cold climate conditions where conventional heat pumps experience reduced performance. These systems utilize advanced technologies such as two-stage compression, enhanced vapor injection, and cascade systems that maintain high coefficients of performance (COP) even when outdoor temperatures drop to -25°C or lower. Design features include larger heat exchanger surfaces, low-temperature optimized refrigerants, and sophisticated defrost systems that minimize energy consumption during icing conditions. Sidite's research in this area has developed systems that deliver heating water at 35-45°C with COP values above 2.0 at -20°C ambient temperature, making them ideal for underfloor heating and low-temperature radiator systems. A residential project in Norway achieved 60% energy savings compared to electric resistance heating, with the system providing reliable space heating throughout Arctic winter conditions. These units include weather-compensated controls that optimize system operation based on outdoor temperatures and heating demand.
