Re: [TRNSYS-users] problem of sky temperatures

Pauline,
  Type69 and Type15 use different algorithms for computing sky temperature. The algorithms are discussed in the 04 Mathematical Reference manual.
Kind regards,

Hello,

 

sorry to ask again the same question but I can’t understand why the values of sky temperature from  weather component type 15 and from component 69 (with inputs from the same type 15) are different.

 

Anyone could help me to understand?

 

Hanks a lot for your answers.

Hello,

 

For a project I would like to check if the effective sky temperature done by the weather type 9 (Meteonorm) is the same than the temperature calculated in the type 69 (with 4 inputs from the type 9).

In fact there are different.

How can we explain that whereas there is the same descriptions?

 

Thank you very much for your answers.

 

Best regards,
