Moliere diagram 2

[gabriels]

Hi,
does anyone knows something about Mollier Diagram for humid air?

 

[MintJulep]

It isi more commonly referred to as a pyschrometric chart.

There is a Mollier Chart for steam. What specifically do you want to know?

BronYrAur,
do u know where i can eventualy download the Molliere diagram.I'm interested in enthalpy on certain temp.of moistured air.
thanx

I sounds to me that you need a psychrometric chart as MintJulep suggested. You can get enthalpy of air and various dry bulb and humidity points.

I'm sure if you do a google search, you will be able to find a free one to download.

Per quark's attached links, I have had personal experience with the handsdownsoftware psych chart, and it is very user friendly and you can easily plot all the typical air conditioning processes

Which one joejoedancer? There are several on that site.

 

[joejoedancer]

psychormetric analysis version 5.1.2.

If you only want the enthalpy of moist air you can use the formula:

h = (1.007t – 0.026) + w (2501 + 1.84t)

Where t is ambient temperature in C and w is specific or absolute humidity. h is specific enthalpy kJ/kg. This equation is valid between 0 and 60C.

I must be missing something, joejoedancer. When I go to the handsdown site, I see several downloads - Trane, Carrier, York, marlo, etc. None are identified at version 5.1.2. Am I in the right place?

Pick the one on the top left corner (i.e Heatcraft Visual Psy Chart). The free version is of atmospheric pressure type.
