AHH is Mollier HX Diagram and Carrier XH Diagram for air humid. Calculate all air technical processes. We offer climate, comfort and control areas to facilitate the planning of complex systems. Interfaces for global meteorological data and office applications are available.

The software is available as a single license as well as floating license for server. The price of a floating license depends on how many clients want to work simultaneously with it.

About using the Mollier HX diagram, you can quickly and accurately represent graphically and numerically changes in the state of humid air by heating, humidification, dehumidification, cooling and mixing of different air flows (so-called thermodynamic processes). The software solution is interactive and shows the process sequences according to Mollier.

The Mollier HX diagram is valid for a specific air pressure, respectively for a defined height over sea level. Temperature, humidity, enthalpy and density are defined in a graphic way. The HX diagram was named in 1923 after  Richard Mollier.

The following values are listed by the Mollier HX diagram in tabular form:

• Temperature
• abs. humidity
• rel. humidity
• Enthalpy
• Density
• Temperature difference
• abs. humidity difference
• Enthalpy
• Capacity

The comfort zone is represented according to DIN 1946 part 2 or to ASHRAE, separated for summer and winter. For the purpose of documentation, any number of text fields can be putted in the Mollier HX diagram.

AHH software works with following ranges:

Temperature:           -100 to 300 ° C,  
Water:                     0 to 1000 g / kg,
Pressure:                 0,1 to 16 bar,
Hieght over sea level:     -5000 to 15000 m.
