help DATA TO BE ANALYSISED BUT DO NOT KNOW HOW?
(OP)
Hi
The is a theatre design I have built, with two levels on it and two platforms either end, at mid height. picture a long retangular space, divided into two levels with aplatform at each end. this is all one enclosed space. I have a temperature data for several areas inside it. The room has to perform in a specified ranges. the readings i have are for every 5 seconds when the ac starts from cold. I need so way of analysing this data using stats. the majority of the said data for the temperature is out side the desired range. what should I do...

Prior to doing any of that, I would agree with GregLocock and corus to take a look at the initial basics of what your data is telling you over time. Does one point come into spec before others? Is response fast enough? Are the room sensors placed in a location that makes sense for controlling room temp?

Is the air actually getting to where it's supposed to?
Is the control system even working?
Is the temperature at the control sensor even correct?
Sounds like you have design or implementation problem, not a statistics problem.

What the data set I have seems to tell me that the process parameters need to be moved or the tolerance adjusted. But thats a a client issue.Anyhow

Large excursions are usually a sign that the control loop is incorrectly tuned for the application. Your EE should be looking at adjusting his control parameters.

I dont have much experience in this field but I would think the test should be run for a period of say 3 hours at least in something that is used all day long.
Is there something I should be doing with the sensors? The time period of dedection is every five seconds and the temperature goes up and down alot in the five seconds any where from 0.2 degrees to 0.7 degrees.
Lets just say it ocillates in the local picture and the overall picture also.
Any good books or articles I should read that may help me make sense of this. I am more into stress and strain stuff but due to having done some work in HVAC b4 I was landed inn this area... but my hvac was in buildings and just envolved the installation of consultants .
Its driving me mad?
