Sir, I want to download this chart,if free.I want to study only.Can u pass e mail to me?Thanks ,Marlar

I tried to use the psychrometric diagram and frankly speaking I had quiet some problems with it.1. As I realized it's based on a chinese software and not all characters are well exposed (SI units).2. I couldn't find a way to adjust the height above sea level. I live in Mexico and we are 2250m above sea level. Most of the projects and HVACR application are at heights of 1500, 2200 and 2600m above sea levels, hence I consider it as a must to have to choice to switch between different heights.3. I prefer a way to key in the values I ...

i need to calculate this space for the following conditions:volume of the space is:V= 331 m3(room volum)sommer:DB=34 grad celciusRH=45%i need in the room DB=18 grad celciusRH=45-50%winterDB=-1 grde celciusRH= 75%I NEED IN THE ROOM AGAIN :DB=18 grad celciusRH=45-50%RESPECT FROM ING .LORENC MALKAi need to calculate the dehumifierand

Temperature range. Your calculator is pretty good and simple to use, but like I'm searching for RH% in a higher temperature range ( over 100в°c) your product donesn't help me enough. If any upgrade created, please tell me. Thank you.
