2. This data indicates the size and capacity of the system. For an analysis of the econo mic and energy efficiency of the syste m, other parameters, such as, in particular , the defrosting
capacity, the bival ence point and regula tion, should also be take n into consideratio n. The specified values, e.g. A2 / W55, have the following meaning: 2 °C external air temperature
and 55 °C heating water flow temperature.
