BITZER has introduced an iPhone app that calculates the pressure to temperature characteristics of refrigerants. The digital refrigerant ruler shows the most current refrigerants, can use imperial and metric units simultaneously and can display them in any desired combination.
The new iPhone app from BITZER, for calculating the pressure-temperature characteristics of refrigerants, is intuitive to use and the user can adapt it to his or her specific needs. With this application BITZER offers a modern alternative to traditional refrigerant ruler. The application features an intuitively operated reference wheel for saturation pressure and temperature.
The app defaults to the most common refrigerants; the user does not have to search through a mass of rare refrigerants but can rather look up those relevant to his or her requirements and sort these into a chosen order. Refrigerants available to date are: R11, R113, R114, R115, R116, R12, R123, R124, R125, R1270, R13, R134a, R14, R142b, R143a, R152a, R21, R218, R22, R227ea, R23, R236fa, R245fa, R290 (propane), R32, R401A, R401B, R401C, R402A, R402B, R403A, R403B, R404A, R405A, R406A, R407A, R407B, R407C, R407D, R407E, R408A, R409A, R409B, R41, R410A, R410B, R411A, R411B, R412A, R413A, R414A, R414B, R415A, R415B, R416A, R417A, R418A, R419A, R420A, R421A, R421B, R422A, R422B, R422C, R422D, R427A, R500, R502, R507A, R508A, R508B, R600a, R717 (ammonia), and CO2 (carbon dioxide).
A further highlight of the BITZER app is that the user can use imperial and metric measurement units at the same time. Moreover these can be displayed in any desired combination - for example, Celsius and psig or Fahrenheit and bar.
The application is also very easy to use. Each point on the pressure wheel represents a refrigerant. By sweeping from left to right over the refrigerant bottle shown the user reaches the desired refrigerant type. The app additionally displays oil types, global warming potential, safety group, and the appropriate pressure-temperature wheel. Touching the wheel also displays the saturation pressure and temperature values. The user sets the units using the buttons at the sides. If a unit appears green, the appropriate values are displayed on the wheel. Pressing on the arrow keys enables the user to jump to one or other end of the wheel. The left-hand arrow leads to the lowest available temperature and the right-hand arrow to the highest. Additional information such as molar mass, critical temperature or critical pressure for each refrigerant can be obtained via the "i" button.
This BITZER app is available now from the iTunes Store:
