RE: [EnergyPlus_Support] Problem with results of a simulation





I am not sure what is your "air heating rate".

 

As your heating load is high during the day, from 6 am, may be you are reporting some roof temperature related variables. 

 

A 750m2 roof can be  receiving 750kW of heat from the sun.  (Assuming 1KW/m2.)  The variation of this intensity can be found by listing the solar radiation related variables in your simulation.

 

If you will post or send  me the IDF, I will have a look at it.

Subject: [EnergyPlus_Support] Problem with results of a simulation

 
Hi,
I'm having some strange results from a simulation in Energy+.
The building is composed by 2 zones,each one of 50X15(m)and a height of 5 meters.
//////////////////

/ 750m2 / 750m2 /

//////////////////
The results of "Ideal Loads Air Heating Rate" are very high,the peak is almost 750000W for each zone.The peak value occurs at 6:00am when the thermostat change the temperature target.(Almost all the days I have this peak).
The results of "Ideal Loads Air Cooling Rate" are normal, the peak is near 25000W for each zone.
I can send the files if someone needs it to help me.
Thanks
P.S.:The simulation is for Malaga(Spain)
