1,1,1,2-Tetrafluoroetana - Wikipedia bahasa Indonesia, ensiklopedia bebas
The refrigerants used in this system are generally hydrofluorocarbon (HFCs), such as R-134a. Meanwhile, the secondary refrigerant that is often used is propylene glycol. R134a is a refrigerant that is often used in refrigeration systems because of its good performance as a medium for conducting heat.
Thermodynamic properties of refrigerant R-134a
Uses. 1,1,1,2-Tetrafluoroethane is a non-flammable gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. These devices began using 1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for the more environmentally harmful R-12. Retrofit kits are available to convert units that ...

R134A PT chart is a standard table. Basically, this 134A PT chart tells you what is the pressure of R134A refrigerant at certain temperatures. The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F). Example: What is the pressure of 134A freon at 85°F? You just chart the chart (found below) and ...
