interpolate

Linear interpolation in the table, as CombiTable2Ds (rows: condenser, columns: source)

FastSmoothBuildings.Hydronics.HeatPumps.Vitocal251A08.interpolate, function (source)

Purpose

Heating capacity (heating = true) or electrical power of the Vitocal 251-A08 at a condenser outlet temperature and a source temperature, by linear interpolation in the table: first along the source temperature TSou in each row, then along the condenser outlet temperature TCon between the rows. Beyond the first and last breakpoints of either axis the value is held at the edge of the table.

Use

The value of the table at design conditions, for the scaling scaFac of HeatPump. It is evaluated from parameters only; the model itself uses the differentiable smoothTable.

Relation to Buildings

Within the table, the linear interpolation of CombiTable2Ds (rows: condenser, columns: source).
