[TRNSYS-users] solar radiation units of weather data type109

[Dimas Firmanda Al Riza]

Hi Laia,

for type 109 I think the input data should be in Watt/m^2, but the output of
type 109 is in kJ/hr.m^2,
you can easily convert the output (kJ/hr.m^2) to (kWatt/m^2) using type 57
(unit conversion routine),
by setting Type 57 parameter as follow:
Table number : 11,
id number for input : 1 and
id number for output : 2

to convert it to Watt/m^2 just use the equation (multiply with 1000)
hope this can help you
