R134a Cycles is an App developed for secondary and university students, focused mainly in the area of Thermodynamic Engineering. My goal is to facilitate the resolution of problems and exercises of the topic "Refrigeration Cycles", integrating internally the tables corresponding to R134a Refrigerant (1,1,1,2-Tetrafluoroethane).
What does the FREE version include?
- Smart Mode, with 4 cycles: Simple-Stage Vapor Compression, Waterfall, With 2 Stages, and with 2 Evaporators *, indicating the refrigeration load (QFF) and the limit temperatures (evaporation and condensation).
- Resolution of States Table, indicating the phase, temperature, pressure, entropy, enthalpy, volume, mass and volumetric flow.
- Graphics of the Installation and Diagram T-S of the cycle.
- Final Results: COP, Power and Heat given to the Environment.
- Energy Balance in Heat Exchanger and Mixing Chamber.
- Compressor performance adjustable between 75% and 100%.
- Change of temperature units to degrees Celsius, Fahrenheit or Kelvin.
- Change of pressure units to Kilo-Pascals, Atmospheres, Bar, Pounds per square inch or Mega-Pascal.
- Change of units of volume to cubic centimeters, cubic decimeters, cubic meters or liters, for each kilogram or gram of mass.
- Search for Values, indicating Pressure and some other variable, such as enthalpy, entropy, temperature or title.
- Credit System to unlock certain specific values.
* For the resolution with 2 Evaporators, you shold use an exclusive section called "Fridge" in which the refrigeration loads corresponding to the Freezer and the Internal Space must be indicated.
Frequent questions:
Q: Where is the enthalpy and entropy zero?
A: In this App, it is located in the saturated liquid state for a temperature of -40 ° C. In future updates, this zero can be modified in the Tools section.
Q: How can I earn credits? **
A: Currently, the method used by the App to generate credits is simply by the use of the user (1 credit is won for each minute), or by the display of ads, with +150 credits in the videos rewarded. In future updates, in-app payments will be included.
Q: Can I avoid loading ads if I use mobile data?
A: Yes. To disable rewarded videos without Wi-Fi connection, enter the Tools section, and activate the option "Data Saving".
Q: How can I see the privacy policy?
A: Enter the Tools section. At the bottom of the "About" section, shortcuts to that policy are available.
Q: If I have any suggestions, how can I contact you?
A: You can write to my email ([email protected]). Your opinion is very important for the continuous improvement of this application.
Q: When will the PRO version be available?
A: As of December 2018. It will be free of ads and will have new tools!
