Характеристики хладагентов
R32 and R290 are both used in modern heat-pump systems, but they have different physical and safety characteristics. R32 is mildly flammable, while R290 is highly flammable and requires specific handling and system safety provisions.
Эффективность зависит не только от хладагента
Seasonal performance depends on the whole system: compressor, heat exchangers, controls, operating temperatures, climate, defrost strategy and hydraulic design. Comparing only the refrigerant does not determine the performance of a complete product.
