According to the developer, “This app offers four different calculations and shows the results both in a pane and on a psychrometric diagram:
1. Air treatment
Calculates how to convert a given ambient air to a required design air. The steps involved are cooling with a given sensible heat factor, dehumidifying, heating and humidifying (adiabatic or steam). Depending on the given and required air conditions, some of these steps may not be needed.
2. Capacities
Calculates the required capacity to cool down or heat up a given amount of air (e.g. air in your room).
3. Heat exchanger
Calculates how warm room air heats up cool ambient air before supplying it as fresh air to the room. While heating up the ambient air, the heat exchanger cools down the room air, which may result in condensate. When the ambient air would be too cold, this calculation dimensions an electric heater to prevent condensate.
4. Carburetor icing
Given a temperature and a dew point temperature, calculates the probability of icing in an airplane carburetor. Graphically shows the danger zones on a diagram.”
