recordVitocal251A08
A2W Vitocal 251 by Viessmann
Extends from GenericAirToWater (Partial record for air-to-water heat pump devices).
Information
Data from the planning book (Planungshandbuch) from Viessmann.
While the product exists in different sizes, this record contains the data for the subtype 251-A08. If you want to model the pressure losses of the device, check out the data sheet and the installed pumps. The pressure loss depends mostly on the hydraulic system according to the datasheet.
The nominal mass flow rate is calculated for the nominal point A7/W35, with a temperature spread of 5 K.
