BITZER REFRIGERANT RULER Avis

These include, for example, GWP and ODP values for the refrigerants, safety group, chemical composition or components in mixtures, CAS number, molecular weight, triple and boiling (bubble) points, critical temperature, critical pressure and information on the type of oil for the compressor.

▸ Ruler: By means of a slider, the values of pressure, dew and boiling (bubble) temperatures (temperature glide resulting from the difference) for the selected refrigerant can be determined.

With this setting, the atmospheric pressure can be entered either manually on the upper ruler or via the "barometer symbol" to correct the pressure values.

▸ Automatic Barometer: The app offers the possibility to determine the current altitude above sea level and/or the actual atmospheric pressure to correct the corresponding dew and bubble temperatures in case of overpressure settings.

Pressure and temperature values can also be entered manually - either by tapping on the respective field or via the symbol "123".

A change to absolute pressure values is possible under "Settings", the atmospheric pressure correction is then inactive.

▸ Settings: Under this menu all important parameters for the determination of the atmospheric pressure as well as for temperature and pressure values can be adjusted.

▸ Search filters and favourites: Under the navigation item "Search" or via predetermined "Search filters" or manual entry in the text field the appropriate refrigerant can be found and, if necessary, added to the favourites by tapping the "star symbol".

In the Setting psig / inHg displays the overpressure values in "psig" and the negative pressure values in "negative inHg" (e.g., -7.5 inHg).

The app contains all common refrigerants, including key fluid properties, safety group information, global warming potential (GWP), ozone depletion potential (ODP), and information on choice of oil type for the compressor.

▸ The app contains data and information on more than 100 natural and synthetic refrigerants, which can also be preselected by filter functions (under "Search").

▸ Temperature / pressure: Temperature and pressure units can be freely selected and combined, if necessary, a mix of SI and IP units is possible as well.

Furthermore, additional information on refrigerants, links to relevant online documents and other information are displayed (under "More..." in the menu bar).

Manually entering the atmospheric pressure or correction is possible as described under “Slider control”.
