[TRNSYS-users] The Front convective Heat Transfer Coefficient of Wall in TYPE 56

[JUAN FRANCISCO BELMONTE TOLEDO]

Hello Yasmina.

 

I think it can be interesting in case you choose the “internal calculation” option in TRNBUILD for the heat transfer coefficient, and you want to know its value. Otherwise the output value must be the same that you entered as an input value.

Dear Mika, 

 

Thank you for you quick answer. 

 

On the TRNSYS manual (chapter 5 –MultizoneBuilding page 5-34) , it’s written that the HCONVI unit is [kJ/hm2K]. I am not sure it’s  a heat transfer rate from the selected surface.

Dear Yasumina,

 

I think HCONVI is not a heat transfer coefficient [kJ/hm2K] but a heat transfer rate [kJ/h] from the selected surfce.

 

Best regards,

Mika

Dear TRNSYS users, 

 

Does anybody know what is the difference between the front convective Heat Transfer Coefficient that you enter in type 56 and the type 56’s output called NType 108 : HCONVI ( eff.inside cinv. Heat transfer coeff (FRONT) ) ?

 

Kind regards,
