I have a few queries about the ambient temp usage but ill wait ubntil ive tried the program. Right just tried it. Im not quite happy with the way ambient is dealt with. The values that come with the peltier modules such as 27 degrees with mine are not really anything to do with ambient temperatures. All it is saying is that the supplied specification are correct when the hot side of the peltier is at 27 degrees.
Of course the hot side of the peltier is going to be a bit above ambient hence they usually give example figures at about 27 and 50 to give example figures for very good and relatively poor cooling of the modules. I wonder if anyone knows any equations that take into account the hot side of the TEC and alter the resistance and other specs of the peltier appropriately.
If I have misunderstood or anyone knows any better, please feel free to correct me, im very new to all this. Edit: looking at your other modules, they all have ambient figures qouted at around ambient. I wonder why there is a difference. Fare enough. Yip your correct Heres some numbers on a watt TEC at different temps. A TEC at I had planned to ask you lot to get accurate numbers for me.
I believe the and the watt TEC to be the same thing but at different temps.. I believe can work out the equation to predict correct Qmax based on "X" Th temp. Can some one find correct data for the and TEC's please. Im glad I understood things correctly. This is where I struggled to find the equations I wanted to get everything worked out precisely.
All I can say about the Th is as ive already said most manufacturers qoute values at 27 degrees and 50 degrees. However, sellers often qoute the 50 degrees values to make the modules sound more powerful.
I'll have a quick look aorund for numbers. Edit: being a bit stupid at the moment, they use 27 degrees c because thats kelvin why they use k im not yet sure but its a nice number and I now assume they sometimes use 50 as an expected normal hot side temperature in the average system. After a quick look I find alot of references to saying the w and w modules are the same but at different temps. It seems to be a CP The specs page doesnt give much info though such as the crucial temperature.
