This diagram shows lines of constant temperature, humidity ratio, relative humidity, enthalpy and specific volume.  - See immediate results of any change on the diagrams and the result panel shows detailed information about a point on the diagram.  The Mollier diagram is heavily used in Eastern Europe and Germany and shows the same lines as in the psychrometrics diagram.  - Select two air properties to define a point: dry bulb temperature, wet bulb temperature, humidity ratio, relative humidity, enthalpy, specific volume and moist air density.  However, this diagram shows the same constant lines as for the other two.  - Choose one of the diagram types (Psychrometrics, Mollier or Dewpoint) for the graphical results.  This is probably the oldest diagram to represent air properties and named after its inventor Richard Mollier (1863-1935).  Hide some constant lines on the selected diagram to simplify it.  Define colors for the diagram lines and the background gradient.  To get a psychrometrics diagram from a Mollier diagram, swap it along the vertical axis and rotate it 90°.  These four calculations show the results in a pane, but also graphically in a diagram.  - Zoom in (two fingers gesture) and pan (one finger gesture) to enlarge and move a part of the diagram.  This is the classic diagram representing different kinds of air properties into a single diagram.  Graphically shows the danger zones on a diagram.  - Click the explain tab to get a short explanation of a calculation or a diagram.  It is easy to read important weather data, such as temperature, dew point and relative humidity.  Given a temperature and a dew point temperature, calculates the probability of icing in an airplane carburetor.  The steps involved are cooling with a given sensible heat factor, dehumidifying, heating and humidifying (adiabatic or steam).  Calculates the required capacity to cool down or heat up a given amount of air (e.g. air in your room).  This diagram is meant for meteorologists and pilots.  - Define the efficiency properties of a heat exchanger, giving you professional results.  While heating up the ambient air, the heat exchanger cools down the room air, which may result in condensate.  Calculates how to convert a given ambient air to a required design air.  Calculates how warm room air heats up cool ambient air before supplying it as fresh air to the room.  Interestingly, the straight lines in the other two diagrams become curved lines in this one and vice versa.  When the ambient air would be too cold, this calculation dimensions an electric heater to prevent condensate.  Depending on the given and required air conditions, some of these steps may not be needed.  Enter data using buttons for small and large value increments.  - Supports five languages (English, French, German, Spanish and Dutch), which you can set in the preferences.  - Choose between metric or imperial unit dimensions, e.g. °C and °F or kW and BTU/h.  You find detailed descriptions in standard books about air treatment, such as ASHRAE.
