Re: [TRNSYS-users] R: high temperature of building

Dear Toni

Thank you for your answer

The heat gains are tuned on , the 4 persons occupancy are considered , lighting , computer etc. I will turn it off and try again, also I have used whether data for the radiation on each wall as well as the roof. If I do not consider that, and Just I use ambient temperature from weather to building type, the temperature will be lower. should I consider radiation ? 

Also I don't know If ideal heating is implemented or not, but the heating option of building is off because I'm using an external HVAC to supply air to building. I have used the attached file to to implement an external HVAC system on my building. I mean that my HVAC system calculates the supply air temperature, flow rate and humidity ratio and it will used as the inlet conditions of ventilation to building. The procedure is explained in the attached file. If anything is wrong please send me your comments. 


Thank you

Hallo Ahmad,

  1. did you check carefully the internal gains? (In case switch them off and try again)
  2. did you check if the IDEAL Heating is implemented in the TRNBUILD File?

Dear all

I have used the type 56b for building. I have  designed a HVAC system and I used the HVAC supply temperature for building ventilation temperature. and I have used the weather type for calculating the radiation on each wall as well as the ambient temperature of building. But my building temperature is higher than both ambient and supply temperature all over the time !  what is the problem?


Thank you
