The
U-Value Calculator is used for rapid calculation of U-Values for layered
constructs.
Data of the layered structure can be saved into a layered construct file (.LayeredConstruct).
Data can also be loaded from material layers file (.MaterialLayers)
or layered construct file (.LayeredConstruct).
A layered construct contains a list of material layers surrounded by two surface
(exterior and interior) boundaries.
For the two surface boundaries one can enter its surface heat transfer
coefficient or transfer resistance. The Menu Edit→Surface
transfer coeffs provides a choice of
normative standard values.
Both name fields of exterior and interior surfaces also provide same choices of
standard normative values.
Material layers are input by the entry of their heat conductance and layer's
thickness. Based on this values the program calculates heat resistance for each
material layer.
The reciprocal value of the sum of resistances of all material layers and both
surface transfers are displayed in the U-Value field.
Actually selected data line is marked by an arrow symbol at its left (data
record mark). Multiple selection is also possible (e.g. for deletion of line
which can be initiated with DEL key).
The complete layered construct can be placed onto the clipboard by the menu
function Edit→Copy to be
pasted later.
