Re: [TRNSYS-users] building model for a cold load simulation

[David BRADLEY <d.bradley@tess-inc.com>]

Leona,
  I would recommend using Type56, not Type19. I think you only need to model 1 zone; the one whose cooling load you want. If you know the temperature of the lobby and the upper room (which I think you can get from the temperature differences) then you define BOUNDARY walls between your zone and those two zones, select a "known temperature" for the BOUNDARY walls' back side condition.
Kind regards,
 David

Dear all,

i want to make a building model for the simulation of cold load.It is just one room with one external wall and 2 unair-conditioned next rooms(one is the lobby the other is the upper room).

Questions are
1. Which Type should i use? 56 or just 19?
2. if i use 56, should i make 5 zones? i need the cold load from one room , and i just have the temperatur differences of this room from 2 other rooms.

Can anyone help me?

 

Thanks and best regards,

Leona
