Title: Maximum and minimum

First of all I make a point of thanking the unit for the users for TRNSYS and in particular Mr David Bradeley.

I think that I have badly to put my question as a result I will reformulate the problems.

 

In fact I want to calculate the Outside temperature maximum you minimal during the month July

 

here an example: Text in Madison pendnat July is the following ones :

Text
1
12
13
14
15
13
15
30
12

14

13

14

..

..

ect

do I want to have a module which me Text calculation maximum and minimal?
maximum (text) =145
Minimum (text) =1.

 

Does no matter who have an idea on this subject?
Thank you in advance.

Bezeid,
  Type55 can be used to find the maximum and minimum value of an input over whatever time period that you want. However, it watches the input as the simulation progresses so can only tell you what the maximum and minimum values found up to the current simulation time. If sounds from what you describe as though you want to preprocess the weather file and find out what the maximum and minimum temperatures are before you run the simulation? I suppose that you could run the simulation for two years, find the min and max the first year and then set them in your control strategy at the end of that year, effectively using them in the second simulation year. It may be easier, however, to open your weather file in Excel beforehand and manually find out what the min and max temperatures are.
Kind regards,
 david

Dear users of Trnsys,

In my model, I want to calculate the maximum and the minimum of outside temperature to use them in a system of regulation.

here an example
Text
1
12
13
14
15
13
15
145
maximum (Text) =145
Minimum(Text)=1.
Does anyone have any idea about that? Thanks in advance.
