Psychro Tools

This unique app allows you creating, simulating and analyzing psychrometric processes in three simple steps:
1. Create a psychrometric process by combining actions such as heating, cooling, humidifying, heat exchanging, mixing air, …etc.
2. Select a climate file with climate records for each hour of the year. There are climate files for each capital of the world, but you can also create your own.
3. Apply the climate records to the process, simulate the different actions and analyze the results.

The app shows you the results in tables at different levels of details, but also on a dynamic psychrometric or Mollier diagram: click on any process point in the diagram to get all information about the air condition of that point. Look up a specific period (hour, day, month, year) and instantly get the required heating and cooling capacities within that period, but also the hour during which there was a maximum need of capacity.

To define a psychrometric process, you have several actions at your disposal, which you can apply between two or more psychrometric points:
- Saturate: cools air from a given psychrometric point to a saturation point at 100% relative humidity. Enter a sensible heat factor (SHF) to let the app calculate the resulting saturation point.
- Condensate: cools the air along the saturation line and dries it through condensation.
- Heat: heats air using a given capacity, up to a given temperature or to a given psychrometric point. For the first two options, the app calculates the target point.
- Cool: cools air using either a given capacity and sensible heat factor (SHF) or up to a given psychrometric point.
- Humidify: humidifies air through steam or water evaporation, using a given humidification amount or up to a given psychrometric point.
- Mix air: mixes air adiabatically from two sources resulting in a mixed air condition.
- Heat exchange: heat or cool ambient air using the exhausted room air. You can choose between a total heat exchanger and a sensible one. Even better, you can also define the characteristics of the heat exchanger.

There are also two specific actions:
- Fixed or dynamic psychrometric points. Dynamic points change each time a new climate record is applied to a process, where fixed points define a steady air condition (e.g. the room air condition).
- Thermostat: a conditional action deciding whether to use a cooling, a heating or ventilation process. It uses temperature and humidity limits to select the process in use.

To let you take off in no time, the app offers demo projects. There is also a manual with a detailed explanation, that you can download for free. This is definitely the tool you need as an air conditioning professional.

Features
- Use demo projects to start from and use them as a template for more complex projects.
- Find a manual on https://www.micriconsult.be/Manuals/PsychroTools_UsersManual.pdf or tap the explain tab to get a short explanation of a calculation or a diagram.
- Enter values using a virtual keyboard or by pressing buttons to increase/decrease values.
- Uses the available virtual keyboard and makes sure the keyboard does not cover the data entry field. However, when using a GBoard keyboard, use its floating property to move the keyboard freely over the screen.
- Select one of the five languages (English, French, German, Spanish and Dutch) in the preferences screen.
- Choose one of the diagram types (Psychrometrics or Mollier) and select the lines to display.
- Choose between metric or imperial unit dimensions, e.g. °C and °F or kW and BTU/h.
- Define parameters for heat exchangers.
- Select colors for the psychrometric diagram, the climate graphs and the report headers.
- Supports light and dark themes.
- The app saves your latest settings and starts up with those settings. Adapts its user interface when you rotate your screen.
- Zoom in (two fingers gesture) and pan (one finger gesture) to enlarge and move a part of the diagram.
