App for refrigeration and air conditioning with twelve technical calculators, refrigerant datasheets and a searchable formula collection. Works completely offline, no account, no tracking.
The app grew out of my web tools collection that used to live at klima.malura.de. The individual browser calculators turned into a proper app that works without a connection and that you can take along to the site or into the plant room.
It has calculators for superheat and subcooling, pressure-temperature conversion, COP, mass flows and pipe friction losses, plus a cooling-load wizard with room-type presets. The substance data comes from CoolProp and sits in 14 refrigerant datasheets with PT and log p–h diagrams. The app speaks four languages with regional number formatting. The basic calculators are free, the advanced features come as a Pro version.
